Stack

Frontend

• Angular 16+
• Material UI
• SCSS

Backend

• Python FastAPI
• MongoDB for data persistence
• openpyxl/pandas for Excel parsing
• motor/pymongo for MongoDB integration

Prerequisites

• Python 3.8+ (recommend using a virtual environment)
• Node.js 16+ and npm
• MongoDB (local or cloud instance)
• pip

Installation & Setup

1. Install MongoDB (Artix/Arch Linux)

Start MongoDB service:

sudo rc-service mongodb start      # OpenRC (Artix default)
# or
sudo systemctl start mongodb      # If using systemd
mongosh --eval "db.runCommand('ping')"
# Should output: { ok: 1 }

2. Backend Setup

1. Navigate to the backend directory:

   cd backend/
   

2. Create and activate virtual environment:

   python -m venv .venv
   source .venv/bin/activate
   

3. Install Python dependencies:

   pip install --upgrade pip
   pip install --break-system-packages -r requirements.txt
   

   If you see an "externally-managed-environment" error, use the --break-system-packages flag as above.

4. Create environment configuration: Create a .env file in the backend/ directory:

   MONGODB_URL=mongodb://localhost:27017
   DATABASE_NAME=mform_bulk_upload
   API_HOST=0.0.0.0
   API_PORT=8000
   

5. Start the FastAPI server:

   uvicorn main:app --reload
   

   The API will be available at http://localhost:8000

3. Frontend Setup

1. Navigate to the frontend directory:

   cd frontend/
   

2. Install Node.js dependencies:

   npm install
   

3. Start the development server:

   ng serve
   

   The frontend will be available at http://localhost:4200
