Helium Frontend

The frontend for Helium, including mobile and web deployments.

Prerequisites

• Dart & Flutter
• Android or iOS Emulator
• ChromeDriver (for Integration Tests)

Getting Started

Development

To build a development versions of the app for Android and iOS, execute:

make build-android
make build-ios

Tun run a development version of the app for web, executing:

make run-devserver

Before commits are made, be sure to also run tests.

make test
make test-integration

When running a local web version of the project but hitting prod APIs, CORS will need to be disabled by passing a flag like --web-browser-flag=--disable-web-security to Flutter so it starts the browser with this disabled.

Platform

The backend platform is served from a separate repository and can be found here. If platform has been provisioned and is running locally, and you would like to run the frontend against the local backend instead of production, run with --dart-define PROJECT_API_HOST=http://localhost:8000, or use PROJECT_API_HOST=http://localhost:8000 make run-devserver.

Note that to reach localhost from within an Android emulator, use 10.0.2.2 instead.

Local Docker (Web)

The web app can be built and served locally in Docker as a static SPA on port 8080.

make

The Docker image serves the built Flutter web assets on http://localhost:8080.
