Getting Started 🚀

Prerequisites

• Node.js v14+ and npm
• MongoDB (local installation or MongoDB Atlas)
• Git

Python FLASK API Setup

1. Navigate to push_ups root

cd ExcersiseDetection

2. Create Virtual Enviornment (if not already made)

python -m venv .venv

3. Activate Virtual Enviornment

source .venv/bin/activate # ON WINDOWS: .venv\Scripts\activate

3. Install Python dependencies

pip install -r requirements.txt

5. Start the Flask API Server

cd push_ups
python3 PushUps.py

Backend Setup

1. Start New Termnial

2. Set up the backend

# Navigate to the backend directory
cd gym-master-backend

# Create virtual enviornmemt (for backend)
python -m venv myenv

# Activate virtual enviornment (for backend)
source myenv/bin/activate # ON WINDOWS: myvenv\Scripts\activate

# Install dependencies 
pip install -r requirements.txt

# Create .env file for configuration
echo 'PORT=5001
MONGODB_URI=mongodb+srv://gym-master:<ASK_FOR_PASSWORD>@gym-master.vjykr.mongodb.net/?appName=gym-master
JWT_SECRET=your_jwt_secret_key 
JWT_EXPIRE=30d' > .env # Duration 30 Days (JWT)

3. Start the backend server

# Start the server
node src/server.js

# You should see output indicating the server is running on port 5001
# and MongoDB is connected

Frontend Setup

1. Open a new terminal window/tab

2. Set up the frontend

# Navigate to the frontend directory from the project root
cd gym-master-frontend

# Install dependencies
npm install

3. Start the frontend development server

# Start the development server
npm start

# This will open the application in your browser at http://localhost:3000
