The browser can then safely log into SignalWire using the **Project ID** and the **JWT**. + +To learn more about generating and using JWT, including all the options available to you, see [Authentication for JavaScript SDK Documentation](#authentication-using-jwt). + +### Authentication using JWT + +The SDKs that run on the client side, like the [JS SDK](/docs/browser-sdk/js) or React Native SDK, cannot safely use the **Project Token** to authenticate your users as you do in the other, server-side SDKs. + +SignalWire uses [JSON Web Tokens (JWT)](https://en.wikipedia.org/wiki/JSON_Web_Token), an open-standard, to authorize browsers and mobile applications without exposing your secure Project Token and Keys in client-side applications. + +### How Does It Work? + +You start by creating a token on your server and specify what capabilities and permissions you'd like your endpoint to have. You can then connect to RELAY within the SDKs using your `Project ID` and `JWT`. + +Think of it as if you are generating a long, temporary password for each endpoint you want to connect. There is no limit to the number of JWTs you can generate. + +### Security + +Security is one of the basic principles of SignalWire and RELAY, and we use JSON Web Tokens for client-side authorization because they are an open, industry standard method of securely representing authorization between two parties. + +RELAY JWT allows you to specify find-grained permissions, or _scopes_, to determine what access rights are granted, as well as expiration and identification. These settings are determined by you and signed by SignalWire when the JWT is created and cannot be altered or tampered with on the client-side. + +### Expiration + +All RELAY JWT have an expiration time, to protect from abuse. When a token's expiration is up, the client will be disconnected from RELAY automatically. + +By default, all RELAY JWT have an expiration time of 15 minutes, but you should create tokens with the shortest possible expiration that makes sense for your application. + +RELAY JWT can also easily be _refreshed_, updating an existing token with a new expiration time. This allows you to create tokens with short expirations that can be frequently extended as required by your application. + +### Resource + +When a client connects using the JavaScript SDK, they are creating an endpoint, in which (assuming they have been granted permission) they can send and receive calls to. This is referred to as the `resource`. + +When generating a token, you can specify the resource name of the client. For example, if a user logs into your application with the username `alice`, you might want to generate tokens for them with the resource name set to `alice`. Now, another application can simply dial "alice", to reach her, or calls made by Alice's app would be seen as coming from "alice". + +If a resource is not set when generating a JWT, a random UUID will be used. + +### Creating Tokens + +To create a new JWT you send a `POST` request to the JWT REST endpoint. The response will contain a JWT and Refresh Token, which are valid immediately. + +**Note:** The JWT is safe to expose to the client, but the `refresh_token` should be kept secret. + +| Parameter | Required | Description | +| -: | - | - | +| `resource` | optional | The endpoint's resource name.

With a few lines of code, you can even set up a full-fledged video conferencing system. Using the client-side SDKs you can add immersive, scalable communication — from video conferences and softphones to click-to-call and mobile gaming — all available right in your own **web pages** and **applications**. + +Depending on your **use case**, you can choose among **two different SDK versions**: + +- [RELAY Browser SDK v3](/docs/browser-sdk/js) +- [RELAY Browser SDK v2](/docs/browser-sdk/v2/js) + +Both SDKs are **JavaScript libraries** that run entirely on the **browser**. + +To help get you started, in the following we will introduce two broad and common use cases: for each of them, we suggest which of the two SDKs is the most indicated to the job. Keep into consideration that, in the near future, all functionality of RELAY Browser SDK v2 will be integrated into RELAY Browser SDK v3, which will become the reference SDK. + +## I am building an audio/video conferencing application + +If what you are building is closely related to an audio/video conferencing application, which for example should allow the existence of **multiple distinct rooms** for joining by multiple people, then the [**RELAY Browser SDK v3**][javascript_sdk] is likely to be the right tool for the job. This doesn't sound like your use case? Then [skip below][sec_relay_sdk]. + +With the **RELAY Browser SDK v3**, you will be able to build web pages that can stream your voice and video to other users connected to the same system. You can let your users join or leave virtual rooms with an extremely simple API. In other words, you can use the RELAY Browser SDK v3 to build your own personalized video conference experience. + +Moreover, you have full granular control over the permissions within your system. You can enable some of your users to only join conference calls, while others could list ongoing calls and jump in to assist from a support Dashboard. Permissions are handled jointly with the authentication system, which uses JWTs, allowing an easy and secure control of your users' capabilities. + +At the moment, the **RELAY Browser SDK v3** does not allow dialing PSTN numbers or SIP endpoints. This will become supported in the near future. For now, it means that all participants should access from a web browser. If you need to dial different endpoints, then perhaps the [RELAY Browser SDK v2][sec_relay_sdk] suits you better. Note, however, that with the RELAY Browser SDK v2 you will have no room support. + +#### Installing the RELAY Browser SDK v3 + +Starting to use the RELAY Browser SDK v3 is as easy as loading a script from a CDN. In fact, that's exactly how you do it: + +```html + +``` + +Then, you can use the global `SignalWire` variable in your application. If you prefer, the JavaScript SDK v3 is also available as a NPM package: + +```shell +$ npm i @signalwire/js +``` + +For getting started with the **RELAY Browser SDK v3**, take a look at our [API reference](/docs/browser-sdk/js). + +## I am building a one-to-one communication app that should dial other browsers or phones {#i-am-building-a-one-to-one-communication-app-which-should-dial-other-browsers-or-phones} + +If what you are building is an application that should allow your users, from their browser, to initiate an audio or video call towards other **browsers**, **phone numbers**, or **SIP endpoints**, then the [**RELAY Browser SDK v2**][relay_sdk] (Relay SDK) is the right choice for you. + +By exploiting SignalWire's powerful and flexible Relay API, the RELAY Browser SDK v2 gives you access to reliable low-latency communication over a broad set of endpoints in a seamless way, both for your users and for the developers. + +As an example, with the RELAY Browser SDK v2 it is extremely easy to build a web-based **call center** application from which the operator can both dial PSTN phone numbers, _and_ perform internal video calls. All with the same API. + +At the moment, the **RELAY Browser SDK v2** does not support the creation and management of virtual rooms. If you need a multi-room experience, the [RELAY Browser SDK v3][sec_javascript_sdk] might be more indicated for you. Note, however, that as of today the RELAY Browser SDK v3 only supports web browser endpoints, so you won't be able to dial PSTN numbers or SIP endpoints while using the RELAY Browser SDK v3.

This preserves important information without carrying over the full history: + +```python +billing = contexts.add_context("billing") \ + .set_consolidate(True) # Summarize previous conversation +``` + +The summary includes key facts and decisions, giving the new context awareness of what happened without the full transcript. + +### Full Reset Contexts + +`full_reset=True` goes further than isolation—it completely replaces the system prompt and clears all state: + +```python +escalation = contexts.add_context("escalation") \ + .set_full_reset(True) # Complete prompt replacement +``` + +Use this when the new context needs to behave as if it were a completely different agent. + +### Combining with Enter/Exit Fillers + +Fillers provide audio feedback during context switches, making transitions feel natural: + +```python +support = contexts.add_context("support") \ + .set_isolated(True) \ + .add_enter_filler("en-US", [ + "Let me transfer you to technical support.", + "One moment while I connect you with a specialist." + ]) \ + .add_exit_filler("en-US", [ + "Returning you to the main menu.", + "Transferring you back." + ]) +``` + +The AI randomly selects from the filler options, providing variety in the transitions. + +## Debugging Context Flows + +When contexts don't behave as expected, use these debugging strategies: + +1. **Check step criteria**: If stuck on a step, the criteria may be too strict. Temporarily loosen them to verify the flow works. + +2. **Verify navigation paths**: Ensure `valid_steps` and `valid_contexts` form a complete graph.

State is then cleared. + +**Timeout:** If the caller is silent for too long, the call may timeout. The post-prompt still executes, but the conversation may be incomplete. Design your post-prompt to handle partial data gracefully. + +**Network disconnection:** If the connection drops unexpectedly, the post-prompt may not execute. Don't rely solely on post-prompt for critical data—consider saving important state via SWAIG function webhooks as the conversation progresses. + +**Function timeout:** Individual SWAIG function calls have timeout limits. If a function takes too long, it returns an error. State updates from that function call won't be applied. + +### Memory and Size Limits + +While the SDK doesn't impose strict limits on state size, keep these practical considerations in mind: + +**Global data:** Keep global_data reasonably small (under a few KB). Large state objects increase latency and memory usage. Don't store base64-encoded files or large datasets. + +**Metadata:** Same guidance—use metadata for small pieces of function-specific data, not large payloads. + +**Prompt substitution:** When state is substituted into prompts, the entire value is included. Very large state values can consume your context window quickly. + +**Best practice:** If you need to work with large datasets, keep them server-side and retrieve specific pieces as needed rather than loading everything into state. + +### Structuring State Effectively + +Well-structured state makes your agent easier to debug and maintain. + +**Flat structures work well:** +```python +self.set_global_data({ + "customer_name": "", + "customer_email": "", + "order_total": 0.0, + "current_step": "greeting" +}) +``` + +**Avoid deeply nested structures:** +```python +# Harder to access and update +self.set_global_data({ + "customer": { + "profile": { + "personal": { + "name": "" # ${global_data.customer.profile.personal.name} is cumbersome + } + } + } +}) +``` + +**Use consistent naming conventions:** +```python +# Good: Clear, consistent naming +self.set_global_data({ + "order_id": "", + "order_items": [], + "order_total": 0.0, + "customer_name": "", + "customer_phone": "" +}) + +# Avoid: Inconsistent naming +self.set_global_data({ + "orderId": "", + "items": [], + "total": 0.0, + "customerName": "", + "phone": "" +}) +``` + +### Debugging State Issues + +When state isn't working as expected: + +1. **Log state in handlers:** +```python +def my_handler(self, args, raw_data): + self.log.info(f"Current global_data: {raw_data.get('global_data', {})}") + # ... rest of handler +``` + +2. **Check variable substitution:** Ensure your `${global_data.key}` references match the actual keys in state. + +3. **Verify update timing:** State updates from a function result aren't available until the *next* prompt or function call.

The server should now be running on port 3000. +Next, let's make an authenticated request to see the SWML generated by our boilerplate application. +For now, we'll use the basic auth generated by the server. +By default, the username is `signalwire`. +Copy the generated password from the terminal on the line starting with `Basic Auth`. + +```bash +curl signalwire:password@0.0.0.0:3000/assistant +``` + +You'll get back a payload of unstructured JSON. +That's right, SWML is JSON! + +To read it more easily, pipe the result into `jq`, or open +`0.0.0.0:3000/assistant` +in the pretty print view available in most browsers. + +This basic SWML script is how the SignalWire cloud platform interacts with your application. +When you configure a SignalWire phone number to call the application, +SignalWire requests and processes SWML from your server. + + + + + +To let SignalWire make requests to your server running locally, +we'll use Ngrok (or your tunneling service of choice) to expose port 3000. + +```bash +ngrok http 3000 +``` + +Verify that the tunneling is working with the same command as before. +Replace `0.0.0.0` with your temporary hosted URL. +You should get the same JSON response. + +```bash +curl https://signalwire:{{password}}@{{generated-url}}.ngrok-free.app:3000/assistant +``` + + + + + +We're almost done! +The final step is to purchase and assign a phone number in your SignalWire Dashboard. +In the Assign Resource menu, select **SWML Script**. +Under **Primary Script**, set **Handle Calls Using** and select **External URL**. +Here, paste the URL you just tested. + +```bash +https://signalwire:{{password}}@{{generated-url}}.ngrok-free.app:3000/assistant +``` + +Lastly, click **Save**. + + + + + +With your application created, server running, tunnel live, and phone number configured, +you can now call and talk to your brand-new Agent at its phone number. + + + + + +## What's next?

This typically reduces latency by 50-200ms compared to webhook-based handlers. For time-sensitive interactions, this improvement is significant. + +**API Rate Limits**: Your external APIs may have rate limits. Since DataMap calls don't go through your server, you can't implement custom rate limiting logic. Consider: +- Choosing APIs with generous rate limits +- Using fallback responses when rate limited +- Monitoring API usage through your provider's dashboard + +**Response Size**: DataMap works best with reasonably-sized JSON responses. Very large responses (>1MB) may cause timeouts or memory issues. If your API returns large datasets, consider: +- Using query parameters to limit response size +- Requesting specific fields only +- Using a handler function instead for complex data processing + +**Caching**: DataMap doesn't cache responses. Each function call makes a fresh API request. If your data doesn't change frequently, consider: +- APIs with built-in caching headers +- Using handler functions with server-side caching for high-frequency lookups + +### DataMap Best Practices + +**DO:** + +- Always set `fallback_output` for every DataMap—users should never encounter silent failures +- Use `${enc:args.param}` for any value in a URL to prevent injection and encoding issues +- Test your DataMap functions with `swaig-test` before deploying +- Store API keys in `global_data` rather than hardcoding them +- Use descriptive function names and descriptions to help the AI choose correctly +- Start simple and add complexity only when needed + +**DON'T:** + +- Put API keys directly in webhook URLs where they might be logged +- Use DataMap for operations that require transactions or rollback +- Assume API responses will always have the expected structure—test edge cases +- Chain multiple DataMap calls for operations that need atomicity +- Forget that DataMap has no access to your server's state or databases +- Use DataMap when you need to transform data beyond simple extraction + +### Debugging DataMap + +When DataMap functions don't work as expected, use these debugging strategies: + +1. **Test the API directly**: Use curl or Postman to verify the API works with your parameters +2. **Check variable substitution**: Ensure `${args.param}` matches your parameter names exactly +3. **Verify JSON paths**: Response field access like `${response.data.items[0].name}` must match the actual response structure +4. **Use swaig-test**: The testing tool shows you exactly what SWML is generated + +```bash +# Test your DataMap agent +swaig-test your_agent.py --dump-swml + +# Look for the data_map section in the output to verify configuration +``` + +### Migrating from Handler Functions to DataMap + +If you have existing handler functions that make simple API calls, consider migrating them to DataMap: + +**Before (Handler Function):** +```python +@AgentBase.tool(name="get_weather", description="Get weather for a city") +def get_weather(self, args, raw_data): + city = args.get("city") + response = requests.get(f"https://api.weather.com?city={city}&key=API_KEY") + data = response.json() + return SwaigFunctionResult( + f"Weather in {city}: {data['temp']}°F, {data['condition']}" + ) +``` + +**After (DataMap):** +```python +weather_dm = ( + DataMap("get_weather") + .description("Get weather for a city") + .parameter("city", "string", "City name", required=True) + .webhook("GET", "https://api.weather.com?city=${enc:args.city}&key=API_KEY") + .output(SwaigFunctionResult( + "Weather in ${args.city}: ${response.temp}°F, ${response.condition}" + )) + .fallback_output(SwaigFunctionResult("Couldn't get weather for ${args.city}")) +) +self.register_swaig_function(weather_dm.to_swaig_function()) +``` + +The DataMap version is more concise, doesn't require the `requests` library, and includes built-in error handling. + diff --git a/website-v2/docs/agents-sdk/swaig-functions/defining-functions.mdx b/website-v2/docs/agents-sdk/swaig-functions/defining-functions.mdx new file mode 100644 index 000000000..06b782dfe --- /dev/null +++ b/website-v2/docs/agents-sdk/swaig-functions/defining-functions.mdx @@ -0,0 +1,647 @@ +--- +title: "Defining Functions" +sidebar_label: "Defining Functions" +slug: /python/guides/defining-functions +toc_max_heading_level: 3 +--- + +# SWAIG Functions + +SWAIG (SignalWire AI Gateway) functions let your AI agent call custom code to look up data, make API calls, and take actions during conversations. + +## What You'll Learn + +This chapter covers everything about SWAIG functions: + +1. **Defining Functions** - Creating functions the AI can call +2. **Parameters** - Accepting arguments from the AI +3. **Results & Actions** - Returning data and triggering actions +4. **DataMap** - Serverless API integration without webhooks +5. **Native Functions** - Built-in SignalWire functions + +## How SWAIG Functions Work + + + SWAIG Function Flow. + + +## Quick Start Example + +Here's a complete agent with a SWAIG function: + +```python +from signalwire_agents import AgentBase, SwaigFunctionResult + +class OrderAgent(AgentBase): + def __init__(self): + super().__init__(name="order-agent") + self.add_language("English", "en-US", "rime.spore") + + self.prompt_add_section( + "Role", + "You are an order status assistant.

It only takes a few minutes to set up a basic example. + +### Connection + +To build your own chat application, you first need to include the SDK in your HTML. + +```html + + +``` + +Then you can interact with the SDK using the global variable `SignalWire`. We'll mainly be interested in the `SignalWire.Chat.Client` class for this guide, but if you'd like to explore this API, feel free to browse the [SDK documentation](/docs/browser-sdk/js/guides). + +To get started, we need to instantiate a `Client` object and then subscribe to the channels that we want to be part of. + +```javascript +const chatClient = new SignalWire.Chat.Client({ + token: token +}) + +try { + await chatClient.subscribe(channels) // channels is an array such as ['office', 'test'] +} catch (error) { + console.error('Error', error) +} +``` + +The `Client` constructor takes a `token` parameter. This is an authentication token that defines (among other things) the channels which the client is allowed to read and write. When you call `chatClient.subscribe`, you must make sure that the channels you're subscribing to are allowed by the token. + +### How to obtain a token? + +Tokens are provided to the client by your own custom server. Your server determines whether the user is actually authorized to access the chat and, if they are, asks SignalWire to emit a token. +The token is supplied to us by the [Backend](#the-backend) section of this guide, which we will explore shortly. For now, replace `` with the localhost address and port of your server. If you're using the code sample below, +replace `` with `http://localhost:8080`. + +```javascript +const reply = await axios.post("http:///get_chat_token", { + member_id: memberId, + channels: channels +}); + +const token = reply.data.token; +``` + +Notice how we specify a member_id (which can be any unique string of your choice) and a list of channels that should be allowed in the token. This interface is not specific to the SignalWire SDK: when you will write your own server, you will be free to specify any parameters you need for the `/get_chat_token` endpoint. + +## The Backend + +The backend is the proxy which should handle all your authentication logic. The backend is responsible to ensure the user requesting the token is authorized to access the chat and, if they are, ask SignalWire to emit a token. +The token from SignalWire is then sent to the frontend to be used to initialize the chat client. + +Consider the Express.js example below: + +```javascript +require("dotenv").config(); +const auth = { + username: process.env.PROJECT_ID, // Project-ID + password: process.env.API_TOKEN, // API token +}; +const apiurl = `https://${process.env.SPACE_URL}`; + +const axios = require("axios") +const express = require("express"); +const bodyParser = require("body-parser"); +const cors = require("cors"); + +const app = express() +const port = 8080 + +app.use(bodyParser.json()); +app.use(cors()); + +app.use(express.static('frontend')) + +app.post("/get_chat_token", async (req, res) => { + const { member_id, channels } = req.body; + + const channelsPerms = {} + for (const c of channels) { + channelsPerms[c] = { read: true, write: true } + } + + const reply = await axios.post( + apiurl + "/api/chat/tokens", + { + ttl: 50, + channels: channelsPerms, + member_id, + state: {}, + }, + { auth } + ) + + res.json({ + token: reply.data.token + }) +}); + +app.listen(port, () => { + console.log(`Example app listening on port ${port}`) +}) +``` + +The backend technology and stack is not relevant. The important part is that the SignalWire Chat REST API is called to [Generate a new Chat Token](/docs/apis/chat/create-chat-token) with the appropriate parameters. + +This is all you need to get the chat up and running. + +## Downloading the existing messages + +After you join a channel, you will likely want to download a list of messages that were sent into that channel. SignalWire stores the messages for you so that you can use the `getMessages` method of the SDK to get the JSON list. + +```js +/** + * Download a list of existing messages from the server. + * @param {string} channel + */ +async function downloadExistingMessages(channel) { + const messages = await chatClient.getMessages({ + channel: channel + }); + + if (!messages?.messages) return; + + for (const msg of messages.messages.reverse()) { + displayMessage(msg, channel); + } +} + +// Download the already existing messages +for (const channel of channels) { + downloadExistingMessages(channel); +} +``` + +For each of the channels we're subscribing to, we call `chatClient.getMessages`. For each message, we then call `displayMessage` to display it in the UI. + +## Receiving incoming messages + +If you want to receive incoming messages for the channels you've subscribed to, you just have to listen to the `message` event. For example: + +```js +/** + * Subscribe to the "message" event. + * This is triggered each time a new message is sent in one of + * the channels we're subscribed to. + */ +chatClient.on("message", (message) => { + displayMessage(message, message.channel); +}); +``` + +This will call `displayMessage` each time a new message is received. + +## Sending a message + +Sending a message is just a method call. This will send your message into the specified channel: + +```js +await chatClient.publish({ + channel: channel, + content: message +}); +``` + +Note that your message doesn't necessarily have to be a string! It can be any JSON-serializable object. + +## Displaying "is typing" indicator + +To display a "member is typing" indicator we can exploit the member state management of the SDK. Each member has an associated state, which can be controlled from the SDK. We can use this state to store a boolean which indicates whether a member is currently typing. The state is shared across all members, so they can update their UI to show the indicator. + +To set the typing state, you will need to subscribe to the `keyup` event for the textarea in which users type their messages. At the end, here is how the state is updated: + +```js +chatClient.setMemberState({ + channels: channels, // list of channels + state: { + typing: true + } +}); +``` + +You can specify any JSON-serializable object as your state. The other members can subscribe to the `member.updated` event to get the state updates. For example: + +```js +// Set of ids of the members who are typing +const typingMemberIds = new Set(); + +chatClient.on("member.updated", (member) => { + if (member.state?.typing) { + typingMemberIds.add(member.id); + } else { + typingMemberIds.delete(member.id); + } +}); +``` + +Here, we check the value of `member.state.typing`. If it's true, we add the member to the set of members who are currently typing. Otherwise, we remove it. + +Wrap up +------- + +We have built a basic chat application.

There +are a few ways to get their URL: some might be easier or better suited based on +your application. In the following sections we review the different methods, +namely REST APIs, JavaScript SDKs, and Programmable Video Conferences. + +### REST API + +If you have a proxy backend (as described in the [Simple Video Demo](/docs/browser-sdk/js/guides/build-a-video-app)), you can query the Rest API for the room sessions. You can either list all room sessions with the [`GET /api/video/room_sessions`](/docs/apis/video/list-room-sessions) endpoint. Or if you have the id of your current room session, you can [`GET /api/video/room_sessions/{id}`](/docs/apis/video/get-room-session). + +The URL for the preview image will be in the attribute, `preview_url` for the room session. If preview is turned off, there'll be a `null` instead of the URL. + +### Realtime API and Video Client SDK + +#### RELAY v3 + +For Realtime API (RELAY v3), you can add an event listener for +[`room.started`](/docs/server-sdk/node/reference/video/client/events#onroomstarted) +event to get new room sessions as they are created. + +#### RELAY v4 + +For Realtime API (RELAY v4), you can add an event listener for +[`onRoomStarted`](/docs/server-sdk/node/reference/video/client/events#onroomstarted) +event to get new room sessions as they are created. + +For the Video Client SDK running in the browser, the `previewUrl` is available in the same [RoomSession](/docs/browser-sdk/js/reference/video/room-session) object you create to start the video call. + +You will find the preview image in the `previewUrl` attribute of the RoomSession object. + +### Programmable Video Conferences + +If you're using SignalWire's Programmable Video Conferences to create and administrate rooms through the Dashboard, you can access the Video Preview by tapping into the [`setupRoomSession`](/docs/platform/video) parameter when setting up the video room in your web page. + +## Refreshing the previews + +### Vanilla HTML/JavaScript + +The previews of the room are regenerated a few times every minute. The content +changes, but the URL remains the same. To keep them up to date in your website, +you should keep on updating them using a timing mechanism like `createInterval`. +For example, using Programmable Video Conferences with AppKit: + +```html + + + + +``` + +### React + +If you are using React, you can use the +`@signalwire-community/react` +package which offers a handy component for rendering room previews.

+
+ + +The **API token** gives full access to SignalWire APIs. +Whoever owns the API token can, for example, delete any room, mute or unmute any participant, and so on without limitations. +You may only use the API token **in your server** to communicate with SignalWire. + +The **Video Room Token** is a limited-scope token that clients can use to access SignalWire APIs without knowing the API token. +Clients must ask your proxy server for a Video Room Token. +Your server will obtain it from SignalWire servers and pass it back to the client. +Video Room Tokens are associated with a given `<_user_, _room_>` pair, so you can think of them as a personal key for a given user to access a given room. +Your server sets the permissions for each Video Room Token, for example, whether they are allowed to mute other users. + + +### Getting a Video Room Token using cURL + +Let's take a look at how our backend will use the API token to get a Video Room Token. +To get a token from the REST API for a user with name "john" and a room "office" with only video muting permissions, we can use this call: + +```shell +curl --request POST \ + --url 'https://your_space_url.signalwire.com/api/video/room_tokens' \ + --user 'project_id:api_token' \ + --header 'Content-Type: application/json' \ + --data '{"user_name": "john", "room_name": "office", "permissions": ["room.self.video_mute"]}' +``` + +You can see a complete list of possible [permissions](/docs/apis/permissions) +and [video token parameters](/docs/apis/video/create-room-token) in our documentation. + +The JSON response from the API will look like this and can be safely sent to the client: + +```json +{ + "token": "eyJ0eXAiOiJWUlQiLCJhbGciOiJIUzUxMiJ9.eyJpYXQiOjE2MzI0OTE3ODAsImp0aSI6ImM2NmU3ODlkLTJmMjItMTIzNC1hNzMzLThlZjA2MzdmNWI2YiIsInN1YiI6ImExNmQ4ZjllLTIxNjYtNGU4Mi01Njc4LWE0ODQwZjIxN2JjMyIsInUiOiJqb2huIiwiciI6Im9mZmljZSIsInMiOlsicm9vbS5yZWNvcmRpbmciXSwiYWNyIjp0cnVlfQ.qYQwQ1PEnzGbAIb1RoVuYLf0mlqApi15wSC2n7QMCFP4M7jOjOIb_Ia_BhKnbnTHb7sI78d2jS7f_qsFV2OHLw" +} +``` + +### Getting a Video Room Token using your own server + +Instead of using `curl`, and to allow for more granular control over permissions alongside user authentication, +we'll create a server to accept an incoming request for a Video Room Token, obtain the Video Room Token, and send it back to the client. +Our server only needs to expose a single endpoint, which we will call `/get_token` (but it can be anything you want). + +```javascript +// Auth constants to be stored in a dotenv file (or equivalent) with gitignore +const auth = { + username: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx", // Project ID + password: "PTxxx...xxx", // API token +}; + +const apiurl = "https:///api/video"; + +// Endpoint to request Video Room Token for video call +app.post("/get_token", async (req, res) => { + let { user_name, room_name } = req.body; + + console.log("Received name", user_name); + + try { + // get the Video Room Token from SignalWire + let token = await axios.post( + apiurl + "/room_tokens", + { + user_name: user_name, + room_name: room_name, + permissions: [ + "room.list_available_layouts", + "room.set_layout", + "room.self.audio_mute", + "room.self.audio_unmute", + "room.self.video_mute", + "room.self.video_unmute", + ], + }, + { auth } + ); + console.log(token.data.token); + + // send the Video Room Token back to the client + return res.json({ token: token.data.token }); + } catch (e) { + console.log(e); + return res.sendStatus(500); + } +}); +``` + +Let's break this piece of code down. + +1. The user's `user_name` will be used to identify them in the video call, so the frontend will send this information when making a request to our `/get_token` endpoint. + Likewise, the `room_name` determines the name of the room to join. + If the room doesn't exist, it will be created automatically. + +2. We send a post request to the `room_tokens` endpoint of SignalWire REST APIs. + The `room_tokens` endpoint sends back a Video Room Token that we can forward to our client. + +Now we have everything we need to start building the frontend. + +## Frontend + +The SignalWire Browser SDK makes it surprisingly easy to integrate video calling into any web application. +It only takes a few minutes to set up the basics. First, we need to include the SDK in our HTML. + +```html + + +``` + +Then you can interact with the SDK using the global variable `SignalWire`. +We'll mainly be interested in the `SignalWire.Video.RoomSession` class for this guide, but if you'd like to explore this API, +please browse the [SDK documentation](/docs/browser-sdk/js). + +Before a user can join a room, we need to make a POST request for a Video Room Token to the backend server endpoint we just created. + +```javascript +const backendurl = ""; // Your backend server. If you server and frontend are in the same directory, you can leave this string empty +let token = await axios.post(backendurl + "/get_token", { + user_name: username, + room_name: roomname, +}); +console.log(token.data); +token = token.data.token; +``` + +Then, to start the video session, we instantiate a new `RoomSession` object and then we join it: + +```javascript +roomSession = new SignalWire.Video.RoomSession({ + token, + rootElement: document.getElementById("root"), // The HTML element in which to display the video +}); + +try { + await roomSession.join(); +} catch (error) { + console.error("Error", error); +} +``` + +The other important key-value parameter to pass is a `rootElement`. +The root element is an empty HTML element in your DOM (for example, a ``). +It will serve as the container for the video stream. +When `roomSession.join` is called, the SDK will join the room, and the video will appear in `rootElement`. + +These pieces are all you need to get the video up and running. +However, we can polish our application by using the Events included on the Room Session object. + +### Using Events + +The Room Session object supports the standard `.on()` method to attach event listeners and the corresponding `.off()` method to detach them. +**You should subscribe to events after the room is created but before joining the room.** Some of the events you might subscribe to are: + +- `room.joined`: you have joined the room +- `room.updated`: a room property has been updated +- `room.ended`: the room has ended +- `member.updated`: a member property has changed (e.g., video muted) +- `member.updated.audio_muted`: the audio_muted state has changed for a member +- `member.updated.video_muted`: the video_muted state has changed for a member +- `member.updated.visible`: the member is now visible in the video layout +- `member.left`: a member left the room +- `layout.changed`: the layout of the room has changed + +Find the complete list in our [API reference](/docs/browser-sdk/js/reference/video/room-session/events). + +Here's how we can use some these events in our example program: + +```javascript +roomSession.on("room.joined", (e) => logevent("You joined the room")); +roomSession.on("member.joined", (e) => logevent(e.member.name + " has joined the room")); +roomSession.on("member.left", (e) => logevent(e.member.id + " has left the room")); +``` + +### Putting it All Together + +All the above ideas can be combined to create the following function, which we'll use (with minor variations) in the frontend. + +```javascript +async function join() { + const username = $("usernameinput").value.trim(); + const roomname = $("roomnameinput").value.trim(); + gotopage("loading"); + + try { + token = await axios.post(backendurl + "/get_token", { + user_name: username, + room_name: roomname, + }); + console.log(token.data); + token = token.data.token; + + try { + try { + roomSession = new SignalWire.Video.RoomSession({ + token, + rootElement: document.getElementById("root"), + }); + } catch (e) { + console.log(e); + } + + roomSession.on("room.joined", (e) => logevent("You joined the room")); + roomSession.on("member.joined", (e) => + logevent(e.member.name + " has joined the room") + ); + roomSession.on("member.left", (e) => logevent(e.member.id + " has left the room")); + + await roomSession.join(); + } catch (error) { + console.error("Something went wrong", error); + } + + gotopage("videoroom"); + } catch (e) { + console.log(e); + alert("Error encountered.

When +streaming, a room can have two different kinds of participants: audience and +members. + +An _audience participant_ can only watch and listen: their own media is not +going to be shared. On the other hand, a _member_ is the typical videoconference +room member: they can watch and listen, but their own media is also shared with +all other participants in the room. Depending on their permissions, members can +also perform other actions, such as changing the layout of the room or playing +videos. + +When streaming, audience participants can be _promoted_ to members and, +vice-versa, members can be _demoted_ to audience participants. + + + + The source code for this application is available on GitHub. + + +## Joining a room + +When using the [Browser SDK](/docs/browser-sdk/js), the kind of +[Video Room Token](/docs/apis/video/create-room-token) that you +get determines whether you join the room as audience or as a member. + +### Joining as audience + +To join as audience, specify `"join_as": "audience"` when creating a token. + +{/* TODO: create examples to join as audience and member */} + + + +```bash +curl -L -X POST "https://$SPACE_URL/api/video/room_tokens" \ + -H 'Content-Type: application/json' \ + -H 'Accept: application/json' \ + -u "$PROJECT_ID:$API_TOKEN" \ + --data-raw '{ + "room_name": "my_room", + "user_name": "John Smith", + "join_as": "audience" + }' +``` + +Then use the returned token to initialize a +[RoomSession](/docs/browser-sdk/js/reference/video/room-session). + +### Joining as a member + +To join as an audience member, specify `"join_as": "member"` when creating a token. + +```bash +curl -L -X POST "https://$SPACE_URL/api/video/room_tokens" \ + -H 'Content-Type: application/json' \ + -H 'Accept: application/json' \ + -u "$PROJECT_ID:$API_TOKEN" \ + --data-raw '{ + "room_name": "my_room", + "user_name": "John Smith", + "join_as": "member" + }' +``` + +Then use the returned token to initialize a +[RoomSession](/docs/browser-sdk/js/reference/video/room-session): + +```js +import * as SignalWire from "@signalwire/js"; + +const roomSession = new SignalWire.Video.RoomSession({ + token: "", + rootElement: document.getElementById("yourVideoElement"), +}); + +roomSession.join(); +``` + +For more information about using tokens to join a video room, please refer to +our [Simple Video Demo](/docs/browser-sdk/js/guides/build-a-video-app). +Follow that guide to learn the basics about instantiating custom video rooms +using the SDKs. + +## Promoting and demoting + +Using the SDKs, you can programmatically promote and demote participants, +to allow the audience participants to interact with the room and vice-versa. + +To promote a member, use the +[promote](/docs/browser-sdk/js/reference/video/room-session/promote) +method: + +```js +await roomSession.promote({ + memberId: "de550c0c-3fac-4efd-b06f-b5b8614b8966", + mediaAllowed: "all", + permissions: [ + "room.self.audio_mute", + "room.self.audio_unmute", + "room.self.video_mute", + "room.self.video_unmute", + "room.list_available_layouts", + ], +}); +``` + +Only members can promote other participants.

In this guide, we will build an audio-only application inspired by the popular Clubhouse. Here is what we are going to build: + + + + + + + +## Overview + +We are going to build an audio-only application inspired by the popular Clubhouse. Our application will run on the browser and will be composed by a frontend written in React, and a small server in Node.js. We will use the SignalWire JavaScript SDK to provide high-quality communication functionality to our application. + +Before starting, a few resources: + +- `` — this repository contains the implementation of our application. The `master` branch contains the full implementation, while the `livewire` branch contains just the UI. +- [JavaScript SDK Technical Reference](/docs/browser-sdk/js) — find here all technical details about the JavaScript SDK. + +## Getting Started + +Clone the repository with the following command: + +```bash +git clone -b livewire https://github.com/signalwire/browser-audioconf-example.git +``` + +We will work from the "livewire" branch, which contains some basic UI to get started. + +To start the project: + +```bash +npm install +npm run start # starts both backend and frontend +``` + +Your server will listen at ``, while the frontend will be available at ``. + +## Server + +We need to build a small server to obtain Room Tokens from SignalWire, and to get the list of active rooms. In essence, the server will do the following: + +- listen on a `/get_token` endpoint for POST requests from the browser. Our server will obtain a Room Token for the requested user name and room name, and will send it back to the browser. +- send events on a WebSocket, to provide the clients with an updated list of rooms and participants whenever a change happens. + +We will write the server in Node.js. Node.js is not a requirement, but it allows us to use the handy SignalWire Realtime SDK. + +### Obtaining your SignalWire API Token + +First, we need to obtain some authentication information from SignalWire. +Login to your Space [here](https://signalwire.com/signin), +and from the left menu go to the "API" page. +Once you have navigated to the API page, click on "Create Token". +Give it a name so that you can identify it later, +and make sure that the "Video" scope is enabled. +Then hit "Save". +After the token is created, you will see it listed in the table. + +Here are the three pieces of information that you need to copy: + +- Project ID +- Space URL +- Token + + + +![The API page shows the active Project ID and Space URL, and a list of API tokens organized by Name, Token, and Last Used.](@image/dashboard/credentials/api-credentials.webp) + + + +You need to put these values in the `.env` file inside the `backend` folder: + +``` +PROJECT_ID=... +API_KEY=... +SPACE=... +``` + +We are now ready to make requests to the SignalWire REST APIs. + + + +It is important that the API tokens are kept confidential. They can be used to make API requests on your behalf. Take extreme care to make sure that the tokens don't get pushed to GitHub. Make sure that the tokens aren't publicly accessible, for example they must not be exposed in frontend code. For Node.js backends, you can use [dotenv files](https://www.npmjs.com/package/dotenv) or similar mechanisms to safely store confidential constants. + + + +### Endpoint: /get_token + +The code of the server is located in the file [backend/src/index.js](https://github.com/signalwire/browser-audioconf-example/blob/master/backend/src/index.js). + +We are now going to create a `/get_token` endpoint to be used by the client to obtain a Room Token for a given room and username. The core instructions in the `/get_token` endpoint look like this: + +```javascript +// Endpoint to request token for a room +app.post("/get_token", async (req, res) => { + const { user_name, room_name } = req.body; + + const response = await axios.post( + apiurl + "/room_tokens", + { + user_name, + room_name: room_name, + permissions: normalPermissions, + }, + { + auth, + } + ); + + const token = response.data?.token; + + return res.json({ token }); +}); +``` + +What we are doing is to listen on POST requests on our `/get_token` endpoint, for a message which contains a JSON-encoded payload such as `{"user_name": "...", "room_name": "..."}`. We use the user name and room name to request a Room Token from SignalWire by making a POST request on the `/room_tokens` endpoint. Note that in this code example, `apiurl` is a SignalWire URL such as `https://.signalwire.com/api/video`. Finally, we send the token back to the client that initiated the request. + + + +The **API token** gives full access to SignalWire APIs. Whoever owns the API token can for example delete any room, mute or unmute any participant, and so on without limitations. You must only use the API token **in your server** to communicate with SignalWire. + +The **Room Token** is a limited-scope token that can be used by clients to access SignalWire APIs without knowing the API token. Clients must ask for a Room Token to your own server, which in turn will obtain it from SignalWire servers and pass it back to the client. Room Tokens are associated to a given \<_user_, _room_> pair, so you can think of them as a personal key to access a given room, by a given user. Your server decides the permissions for each individual Room Token, for example whether they are allowed to mute other users. + + + +### WebSocket: rooms_updated + +The implementation for this feature is also located in [backend/src/index.js](https://github.com/signalwire/browser-audioconf-example/blob/master/backend/src/index.js). + +We use [Socket.IO](https://socket.io) to create a WebSocket over which to send a list of rooms and, for each room, the list of participants inside. We want to send the updates whenever there is a change. + +First, we write a function to obtain the list of rooms and participants using the REST APIs: + +```javascript +async function getRoomsAndParticipants() { + // Get all most recent room sessions + let rooms = await axios.get(`${apiurl}/room_sessions`, { auth }); + rooms = rooms.data.data; // In real applications, check the "next" field. + + // Filter to get only the in-progress room sessions + rooms = rooms.filter((r) => r.status === "in-progress"); + + // Augment each room session object with the list of participants in it + rooms = await Promise.all( + rooms.map(async (r) => ({ + ...r, + members: ( + await axios.get(`${apiurl}/room_sessions/${r.id}/members`, { auth }) + ).data.data, + })) + ); + + return rooms; +} +``` + +In this case we use two different SignalWire endpoints: the first, `/room_sessions`, gives us a list of room sessions. This however does not include information about the participants, so we use the endpoint `/room_sessions/:id/members` to get a list of members for the given room session id. We pack everything in an array, and we return it asynchronously. + +We use the `getRoomsAndParticipants` function whenever we detect an update using the SignalWire Realtime SDK. The Realtime SDK allows listening to events from rooms, sessions, and members. Here is how we do it: + +```javascript +// We create a SignalWire Realtime SDK client. +const realtimeClient = await createClient({ + project: auth.username, + token: auth.password, +}); + +// Function that sends a `rooms_updated` events over Socket.IO. +const emitRoomsUpdated = async () => + io.emit("rooms_updated", await getRoomsAndParticipants()); + +// When a new Socket.IO client connects, send them the list of rooms +io.on("connection", (socket) => emitRoomsUpdated()); + +// When something changes in the list of rooms or members, trigger a new +// event. +realtimeClient.video.on("room.started", async (room) => { + emitRoomsUpdated(); + room.on("member.joined", () => emitRoomsUpdated()); + room.on("member.left", () => emitRoomsUpdated()); +}); +realtimeClient.video.on("room.ended", () => emitRoomsUpdated()); + +await realtimeClient.connect(); +``` + +We use Socket.IO to emit a `rooms_updated` event that the clients will listen to and update their user interface. + +## Frontend + +### File structure + +We implement the frontend as a React application. We have structured the UI around three pages: + +- [frontend/src/pages/**LoginPage.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/pages/LoginPage.js): the initial login page +- [frontend/src/pages/**RoomListPage.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/pages/RoomListPage.js): the page that will display a list of rooms, allowing the user to join one or create a new one +- [frontend/src/pages/**RoomPage.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/pages/RoomPage.js): the page showing the participants within a room + +We also have several components, but we are mainly interested in two files: + +- [frontend/src/components/**Audio.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/components/Audio.js): contains the logic to connect with SignalWire by using the SignalWire JavaScript SDK +- [frontend/src/components/**Server.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/components/Server.js): contains the logic to connect to our own server and obtain information from the endpoints that we have prepared (i.e., getting a Rom Token). + +We will start by writing the logic in [Server.js](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/components/Server.js). + +### Server.js + +#### getToken + +First, we implement the getToken function. This function performs a POST request to our `/get_token` endpoint specifying a room name and a user name, and returns a Room Token. + +```javascript +export async function getToken(user, room) { + const response = await axios.post(`${url}/get_token`, { + user_name: user, + room_name: room, + }); + return response.data.token; +} +``` + +This is all we needed for what concerns the communication with the server. Indeed, refreshing the list of rooms is handles in RoomListPage.js, like this: + +```javascript +const socket = socketIOClient(Server.url); +socket.on("rooms_updated", (rooms) => { + setRooms(rooms); + setIsLoading(false); +}); +``` + +The above code connects the WebSocket and, whenever it receives a `rooms_updated` events, refreshes the list of rooms in the UI. + +We can now connect to a room using the SignalWire JavaScript SDK. + +### Audio.js + +In [frontend/src/components/**Audio.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/components/Audio.js) we have the logic to connect with SignalWire by using the SignalWire JavaScript SDK. In particular, we have a function declared as follows: + +```javascript +async function Audio({ + room, + user, + onParticipantsUpdated = () => { }, + onParticipantTalking = () => { }, + onMutedUnmuted = () => { }, +}) +``` + +Here, `room` and `user` are strings that indicate the respective names. The parameter `onParticipantsUpdated` is a function that we must call whenever the list of participants changes, and receives the list of participants. The UI will handle it. Similarly, we must call `onParticipantTalking` when a given participant starts or stops talking, and `onMutedUnmuted` when we get muted or unmuted. The React UI in the application uses these callbacks to update the interface. + +We will proceed in steps: + +1. We will create a RoomSession object with a Room Token. +2. We will connect events to detect whenever the list of participants has been updated. +3. We will connect events to detect whenever we get muted or unmuted. +4. We will connect events to detect when a participant is talking. +5. We will join the room session. + +#### Step 1: creating a RoomSession object + +Make sure that the package `@signalwire/js` is installed, and is at version v3.5.0 or higher. + +First, let's import both the SignalWire SDK and our Server file: + +```javascript +import * as SignalWire from "@signalwire/js"; +import * as Server from "./Server"; +``` + +We use the Server component to get a token: + +```javascript +const token = await Server.getToken(user, room); +``` + +Then, we create a RoomSession object specifying the token and some settings: + +```javascript +const roomSession = new SignalWire.Video.RoomSession({ + token: token, + audio: true, + video: false, +}); +``` + +Here, we have specified that we only want to use audio functionality. + +#### Step 2: participants-related events + +Before actually joining the room session, we are going to connect some events. Here, we connect all events that indicate a variation in the list of members. In the event handlers, we call `onParticipantsUpdated` to let the UI know the updated list of members. + +```javascript +// Internal list of members +let members = []; + +roomSession.on("room.joined", async (e) => { + console.log("Event: room.joined"); + const currMembers = await roomSession.getMembers(); + members = [...currMembers.members]; + onParticipantsUpdated(members); +}); + +roomSession.on("member.joined", (e) => { + console.log("Event: member.joined"); + members = [...members, e.member]; + onParticipantsUpdated(members); +}); + +roomSession.on("member.updated", (e) => { + console.log("Event: member.updated"); + const memberIndex = members.findIndex((x) => x.id === e.member.id); + if (memberIndex < 0) return; + members[memberIndex] = { + ...members[memberIndex], + ...e.member, + }; + onParticipantsUpdated([...members]); +}); + +roomSession.on("member.left", (e) => { + console.log("Event: member.left"); + members = members.filter((m) => m.id !== e.member.id); + onParticipantsUpdated([...members]); +}); +``` + +#### Step 3: muted/unmuted events + +We need to detect when we get muted or unmuted. This may happen for example if an administrator mutes us. If we have been muted or unmuted, we call `onMutedUnmuted`. + +```javascript +roomSession.on("member.updated", (e) => { + // Have we been muted/unmuted? If so, trigger an event. + if (e.member.id === roomSession.memberId) { + if (e.member.updated.includes("audio_muted")) { + onMutedUnmuted(e.member.audio_muted); + } + } +}); +``` + +#### Step 4: talking-related events + +We need to detect when a user starts or stops speaking, so that the UI can update accordingly. Whenever we detect such event, we call `onParticipantTalking` passing the id of the participant and whether they are currently talking. + +```javascript +roomSession.on("member.talking", (e) => { + console.log("Event: member.talking"); + onParticipantTalking(e.member.id, e.member.talking); +}); +``` + +#### Step 5: join the room session + +Now that all events are connected, we can join the room! + +```javascript +await roomSession.join(); +console.log("Joined!"); + +return roomSession; +``` + +We return the RoomSession object so that its methods (e.g., audioMute) can be used from the outside. + +Find the full code at [frontend/src/components/**Audio.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/components/Audio.js). + +### Muting the microphone + +Right now, the button to mute the microphone does not work. We can make it work by connecting it in [frontend/src/pages/**RoomPage.js**](https://github.com/signalwire/browser-audioconf-example/blob/master/frontend/src/pages/RoomPage.js). In that file, there is a function named `toggleMute`, which is called whenever a user clicks on the mute button. In addition, inside RoomPage we have a reference to the RoomObject returned by Audio.js: it is stored as `roomSession.current`. + +We can then mute or unmute the user as follows: + +```javascript +function toggleMute() { + if (!roomSession.current) return; + + // The RoomSession object returned by the Audio function is + // stored in `roomSession.current`. + + if (muted) { + // We need to unmute + roomSession.current.audioUnmute(); // <-- add this + } else { + // We need to mute + roomSession.current.audioMute(); // <-- add this + } + + setMuted(!muted); +} +``` + +## Wrap up + +We have built a Clubhouse-like application with the SignalWire JavaScript SDK. + +You can find the full code for this application in the master branch of our GitHub repository [here](https://github.com/signalwire/browser-audioconf-example). + +## Sign Up Here + +If you would like to test this example out, [create a SignalWire account and Space](https://m.signalwire.com/signups/new?s=1). + +Please feel free to reach out to us on our [Community Discord](https://discord.com/invite/F2WNYTNjuF) or create a Support ticket if you need guidance! + +## As Seen on LIVEWire + +If you want to see a live code breakdown, explanation, and demonstration of this guide at work, [click here](https://www.youtube.com/watch?v=gEpzM_wzMrU&t=321s) or check it out below to watch it on YouTube!

Ensure the room is embedded in a secure application accessible only to users who you would like to be able to stream. + + + +# Connecting the stream with REST APIs + +We can also use the REST APIs to connect a room to the stream. We need five things: + +- Your Space name. This is the `` in your Space URL `.signalwire.com` +- Your Project Id. +- Your API token. +- The UUID of the room you want to stream. From your SignalWire Space, open the configuration page for your room: you will find the UUID below your room's name, which will look like this: `431dcfbe-2218-44ae-7e2f-b5a11a9c79e9`. +- The final RTMP URL. If you don't have a stream key, simply use the stream URL that you copied from the streaming service. If you also have a stream key, append it to the stream URL, separated by a slash. Like this: `rtmp:///`. + +We are now ready to associate the stream with the room. + +If you are using a room with UI included: + +```bash +curl --request POST 'https://.signalwire.com/api/video/conferences//streams' \ + --header 'Content-Type: application/json' \ + --header 'Accept: application/json' \ + -u ":" + --data-raw '{ + "url": "" + }' +``` + +If you are using a room without UI included: + +```bash +curl --request POST 'https://.signalwire.com/api/video/rooms//streams' \ + --header 'Content-Type: application/json' \ + --header 'Accept: application/json' \ + -u ":" + --data-raw '{ + "url": "" + }' +``` + +You can now start the room by joining it. You should be able to see your stream in the streaming service within a few seconds. + + + +As with setting up a stream in the Dashboard UI, setting the stream with the REST API will automatically start the outbound stream in any active instance of the room. Ensure the video conference is embedded in a secure application accessible only to users who you would like to be able to stream. + + + +# Connecting the stream with SDKs + +Finally, you may choose to use the Video SDK to set up the stream. With this option, you can build an application that starts and stops the RTMP stream. You can see a [full demo application](https://github.com/signalwire/guides/tree/main/Video/RTMP-Streaming) on the Guides Repo. + +For this demo, we first created a PVC in the Video Dashboard and copied the embed code. We pasted the embed code in an html file and added buttons to start and stop the stream. + +```html +
+ +
+
+ + + + +
+

+ If your streaming service provides a stream key, append it to the stream URL, + separated by a slash. +
+ ex: rtmp://<stream_url>/<stream_key>. +

+
+
+``` + +Later, we will put click handlers on the start and stop buttons to call [`startStream`](/docs/browser-sdk/js/reference/video/room-session/start-stream) and [`stopStream`](/docs/browser-sdk/js/reference/video/room-session-stream#stop) respectively. The [`startStream`](/docs/browser-sdk/js/reference/video/room-session/start-stream) function is available on the Room Session object, so first we need to use the [`setupRoomSession`](/docs/platform/video) callback function on the PVC to get that object. So, the `VideoConference` constructor at the end of the embed script should look like this: + +```js +SignalWire.AppKit.VideoConference({ + token: "vpt_40b...458", + setupRoomSession: setRoomSession, +}); +``` + +We can then access `setRoomSession` in the external JavaScript file and use the Room Session object returned to set event listeners and click handlers. The JavaScript file will look something like this: + +```js +let roomSession; +let stream; + +const stopStream = () => { + if (stream) { + stream.stop(); + } +}; + +const setRoomSession = (session) => { + roomSession = session; + roomSession.on("room.left", () => { + stopStream(); + }); +}; + +document.addEventListener("DOMContentLoaded", () => { + document.getElementById("rtmp-form").onsubmit = async (e) => { + e.preventDefault(); + + const url = document.getElementById("stream-url").value; + try { + stream = await roomSession.startStream({ url }); + } catch (error) { + console.log(error); + alert( + "There was an error starting the stream. Please check your URL and try again." + ); + } + }; + + document.getElementById("stop").onclick = (e) => { + e.preventDefault(); + try { + stopStream(); + } catch (e) { + console.log(e); + } + }; +}); +``` + +The full demo application has some cosmetic additions, but these two files are all you need to get an RTMP outbound stream set up from any application with an embedded PVC. You should be able to see your stream in the streaming service within a few seconds of pressing "Start Stream". + +While this demo used a PVC, you can use the same methods on a video room without the prebuilt UI. For a complete guide on building video rooms without a prebuilt UI, see [Simple Video Demo](/docs/browser-sdk/js/guides/build-a-video-app). From there, you can add start and stop stream buttons and hook them up in the same way as above. + +# Wrap up + +We showed the options to configure an RTMP stream that allows you to stream the content of your video room to any compatible streaming service: the Dashboard UI, a POST request, or an SDK application is all you need. + +# Resources + +- [API Streams Reference](/docs/apis/video/list-room-streams) +- [SDK Streaming Demo](https://github.com/signalwire/guides/tree/main/Video/RTMP-Streaming) +- [SDK Streaming Reference](/docs/browser-sdk/js/reference/video/room-session-stream) +- [PVC Reference](/docs/platform/video) diff --git a/website-v2/docs/browser-sdk/guides/video/switch-webcam-or-microphone-with-signalwire-video-api.mdx b/website-v2/docs/browser-sdk/guides/video/switch-webcam-or-microphone-with-signalwire-video-api.mdx new file mode 100644 index 000000000..8a3906015 --- /dev/null +++ b/website-v2/docs/browser-sdk/guides/video/switch-webcam-or-microphone-with-signalwire-video-api.mdx @@ -0,0 +1,90 @@ +--- +title: Switch devices during calls +slug: /js/guides/switch-devices +x-custom: + ported_from_readme: true + tags: + - product:video + - language:javascript + - sdk:relaybrowser +sidebar_custom_props: + platform: javascript +toc_max_heading_level: 3 +--- + +SignalWire Video API allows you to host real-time video calls and conferences on your website.

SignalWire Video SDK chooses the preferred input devices by default on setup.

+
+ +In a production setting, your server should authenticate your users, manage their permissions, get appropriate tokens for members +and relay the tokens from the SignalWire's Video REST APIs to the client's browser. + +The following code will create a new endpoint at `/api/token`, which will query SignalWire and serve tokens given at least a valid +`room_name`. It also takes additional `user_name` and `mod` parameters. The `user_name` parameter simply sets the display name +for the user requesting the token. The `mod` parameter (short for "moderator" in this case) selects between the two sets of +permissions defined in `permissions.ts` which can be assigned to the user. + +Note that the location of this file ensures that this will run server-side at `api/token` endpoint. +Learn more about Next.js routing [here](https://nextjs.org/docs/routing/introduction). + + + + + +```tsx title="pages/api/token.ts" +import axios from "axios"; +import { FULL_PERMISSIONS, GUEST_PERMISSIONS } from "../../data/permissions"; + +const AUTH = { + username: process.env.PROJECT_ID as string, + password: process.env.API_TOKEN as string, +}; +const SPACE_NAME = process.env.SPACE_NAME as string; + +export default async function handler(req: any, res: any) { + const { room_name, user_name, mod } = req.query; + + if (room_name === undefined) return res.status(422).json({ error: true }); + + try { + const tokenResponse = await axios.post( + `https://${SPACE_NAME}.signalwire.com/api/video/room_tokens`, + { + room_name, + user_name, + enable_room_previews: true, + permissions: mod === "true" ?

For Next.js, an easy addition would be [next-auth](https://next-auth.js.org/). + +You might also want to check if the users requesting mod permissions have the authorization to actually do so in your +system. + + + +To quickly go over various parts of this code: + +1. The constants `FULL_PERMISSIONS` and `GUEST_PERMISSIONS` are arrays of strings representing the permissions given to the user. So + while `FULL_PERMISSIONS` might look like `[..., 'room.member.video.mute', 'room.member.remove', ...]`, `GUEST_PERMISSIONS` would + look like `[..., 'room.self.video.mute']`, indicating that guest is not allowed to mute or remove any other user. + + SignalWire offers a flexible permission system so you can give users all combination of permissions as required. + Permissions are described [here](/docs/apis/permissions). + +2. The constant `AUTH` is a structure that assigns your SignalWire Project ID as the username, and the API token as password. + You will find the Project ID and API token at your SignalWire Dashboard ([explained here](/docs/browser-sdk/js/guides/build-a-video-app#obtaining-your-api-key-and-project-id)). We will use this for [basic auth](https://en.wikipedia.org/wiki/Basic_access_authentication) to authenticate with the SignalWire REST API. + + The constant `SPACE_NAME` is your SignalWire username which you also use as the subdomain to access your Dashboard. + +3. We perform an HTTP POST request using Axios to the [room_tokens](/docs/apis/video/create-room-token) endpoint. + We will send the name of the room, the name of the user, and the array of permissions for the user to this endpoint. + We will also give axios the Project ID and the API token to be encoded as basic authentication header. + + If all goes well, the SignalWire server will send us a token that we can forward to the client. + + + ![Thunder Client showing a GET query being used to test the /api/token endpoint.](@image/project/zoom-clone-2/backendtest.webp) + + +This simple backend will suffice to be able to conduct video conferences. But we will have one more endpoint to add here +to support room previews. + +## Frontend + +We will rely heavily on the SignalWire Community React library ([@signalwire-community/react](https://www.npmjs.com/package/@signalwire-community/react)) to write the frontend. + +### Basic Video Feed + +Consider the following piece of code. + +```tsx title="pages/rooms/[roomName]/index.ts" +// other imports +import { Video } from "@signalwire-community/react"; + +export default function Room() { + const router = useRouter(); + const { roomName, userName, mod } = router.query; + const [roomSession, setRoomSession] = useState(); + + const { data: token } = useSWRImmutable( + roomName !== undefined + ? `/api/token?room_name=${roomName}&user_name=${userName}&mod=${mod}` + : null + ); + + if (!router.isReady) { + return Loading; + } + + if (roomName === undefined || roomName === "undefined") return Error; + + return ( + + {token?.token && ( + + ); +} +``` + +A few things to note about this code are: + +1. Next.js router places it at `/rooms/[roomName]` where `roomName` can be any URL-safe string. So `/rooms/guest` should take you + to the guest room automatically. The dynamic `roomName` parameter is accessible at `useRouter().query.roomName`. The `userName` and + `mod` parameters should come from the URL query string (`/rooms/guest?userName=user&mod=false`) + +2. We are using the immutable variant of the [swr library](https://swr.vercel.app/) to load the token. The React hook `useSWRImmutable` + sends a GET request to `/api/token` just once after it is instantiated. + we made `/api/token` in the previous section. We are using swr + for convenience here, but you are free to use any way to `HTTP GET /api/token`. + +3. The `
