Quick Start

Backend Setup

1. Navigate to backend directory:

cd backend

2. Create virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

pip install fastapi uvicorn openai python-dotenv

4. Create .env file:

cp .env.example .env
# Add your OpenAI API key to .env

5. Run the backend:

uvicorn main:app --reload --port 8000

Frontend Setup

1. Navigate to frontend directory:

cd frontend

2. Install dependencies:

npm install

3. Run the development server:

npm run dev

4. Open http://localhost:3000

Usage

1. Enter a description of what you want to build
2. Select your target programming language
3. Optionally specify project goals
4. Choose whether to generate tests and documentation
5. Click "GENERATE CODE"
6. View generated code, tests, and documentation in tabs
7. Copy or download the results
