# Izaac 2.1 Project
This project consists of a Django backend and a React/TypeScript frontend. Below are instructions for setting up and running both parts in development mode.
## Prerequisites
- Python 3.x
- Node.js (LTS version recommended)
- npm or yarn
- SQLite (included with Python)
## Backend Setup
1. Navigate to the backend directory:
```bash
cd backend
```
2. Create and activate a virtual environment:
```bash
python -m venv venv
source venv/bin/activate # On Windows use: venv\Scripts\activate
```
3. Install dependencies:
```bash
pip install -r requirements.txt
```
4. Run database migrations:
```bash
python manage.py migrate
```
5. Start the development server:
```bash
python manage.py runserver
```
The backend will be available at `http://localhost:8000`
## Frontend Setup
1. Navigate to the frontend directory:
```bash
cd frontend
```
2. Install dependencies:
```bash
npm install
# or if you use yarn:
yarn install
```
3. Start the development server:
```bash
npm run dev
# or if you use yarn:
yarn dev
```
The frontend will be available at `http://localhost:5173`
## Development
- Backend API documentation is available at `http://localhost:8000/api/docs/` when the server is running
- Frontend hot-reloading is enabled by default
- Backend hot-reloading is enabled by default with Django's development server
## Project Structure
- `/backend` - Django backend application
- `/frontend` - React/TypeScript frontend application
- `/nginx` - Nginx configuration files
## Additional Notes
- Make sure both backend and frontend servers are running simultaneously for full functionality
- The backend uses SQLite as the database by default
