# Backend Quick Start Guide
|
||||
|
||||
## Initial Setup
|
||||
|
||||
### 1. Install Dependencies
|
||||
|
||||
```bash
|
||||
cd /home/ren/Documents/math2/backend
|
||||
npm install
|
||||
```
|
||||
|
||||
### 2. Configure Environment Variables
|
||||
|
||||
```bash
|
||||
cp .env.example .env
|
||||
nano .env # Edit with your configuration
|
||||
```
|
||||
|
||||
**Required variables to update:**
|
||||
- `DATABASE_URL` - PostgreSQL connection string
|
||||
- `JWT_SECRET` - Generate a secure random string
|
||||
- `AI_API_KEY` - Your AI service API key
|
||||
- `TELEGRAM_BOT_TOKEN` - Your Telegram bot token (if using)
|
||||
|
||||
### 3. Generate Prisma Client
|
||||
|
||||
```bash
|
||||
npm run prisma:generate
|
||||
```
|
||||
|
||||
### 4. Create and Run Migrations
|
||||
|
||||
```bash
|
||||
# Create initial migration
|
||||
npm run prisma:migrate
|
||||
|
||||
# Or reset database (WARNING: deletes all data)
|
||||
npm run prisma:reset
|
||||
```
|
||||
|
||||
### 5. Seed Database
|
||||
|
||||
```bash
|
||||
npm run prisma:seed
|
||||
```
|
||||
|
||||
This will create:
|
||||
- 3 Modules (Fundamentos, Sistemas/Espacios, Aplicaciones)
|
||||
- 5 Topics (Vectores, Matrices, Sistemas, Espacios Vectoriales, Programación Lineal)
|
||||
- 18 Achievements/Badges
|
||||
- System configuration
|
||||
|
||||
### 6. Start Development Server
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
```
|
||||
|
||||
The API will be available at `http://localhost:3001`
|
||||
|
||||
## Development Workflow
|
||||
|
||||
### Running the Server
|
||||
|
||||
```bash
|
||||
# Development with hot reload
|
||||
npm run dev
|
||||
|
||||
# Production build
|
||||
npm run build
|
||||
npm start
|
||||
```
|
||||
|
||||
### Database Operations
|
||||
|
||||
```bash
|
||||
# Open Prisma Studio (GUI)
|
||||
npm run prisma:studio
|
||||
|
||||
# Generate client after schema changes
|
||||
npm run prisma:generate
|
||||
|
||||
# Create migration
|
||||
npm run prisma:migrate
|
||||
|
||||
# Reset database
|
||||
npm run prisma:reset
|
||||
|
||||
# Seed database
|
||||
npm run prisma:seed
|
||||
```
|
||||
|
||||
### Code Quality
|
||||
|
||||
```bash
|
||||
# Type checking
|
||||
npm run type-check
|
||||
|
||||
# Linting
|
||||
npm run lint
|
||||
npm run lint:fix
|
||||
|
||||
# Format code
|
||||
npm run format
|
||||
|
||||
# Run tests
|
||||
npm test
|
||||
npm run test:watch
|
||||
npm run test:coverage
|
||||
```
|
||||
|
||||
## API Endpoints (Placeholder)
|
||||
|
||||
Once routes are implemented:
|
||||
|
||||
### Health Check
|
||||
- `GET /health` - Server health status
|
||||
- `GET /api/health` - API health status
|
||||
|
||||
### Authentication
|
||||
- `POST /api/auth/register` - Register new user
|
||||
- `POST /api/auth/login` - Login
|
||||
- `GET /api/auth/me` - Get current user
|
||||
|
||||
### Modules
|
||||
- `GET /api/modules` - List all modules
|
||||
- `GET /api/modules/:id` - Get module details
|
||||
|
||||
### More endpoints to be implemented...

|
||||
## Troubleshooting
|
||||
|
||||
### Database Connection Issues
|
||||
|
||||
1. Check PostgreSQL is running:
|
||||
```bash
|
||||
sudo systemctl status postgresql
|
||||
```
|
||||
|
||||
2. Test connection:
|
||||
```bash
|
||||
psql -h localhost -U mathuser -d mathdb
|
||||
```
|
||||
|
||||
3. Check DATABASE_URL in .env
|
||||
|
||||
### Prisma Issues
|
||||
|
||||
1. Regenerate client:
|
||||
```bash
|
||||
npm run prisma:generate
|
||||
```
|
||||
|
||||
2. Reset migrations:
|
||||
```bash
|
||||
npm run prisma:reset
|
||||
```
|
||||
|
||||
3. Check schema:
|
||||
```bash
|
||||
npm run prisma:studio
|
||||
```
|
||||
|
||||
### Port Already in Use
|
||||
|
||||
```bash
|
||||
# Find process using port 3001
|
||||
lsof -i :3001
|
||||
|
||||
# Kill process
|
||||
kill -9 <PID>
|
||||
|
||||
# Or change port in .env
|
||||
PORT=3002
|
||||
```
|
||||
|
||||
### Redis Connection Issues
|
||||
|
||||
1. Check Redis is running:
|
||||
```bash
|
||||
redis-cli ping
|
||||
```
|
||||
|
||||
2. Start Redis:
|
||||
```bash
|
||||
sudo systemctl start redis
|
||||
```
|
||||
|
||||
3. Check connection settings in .env
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Implement Routes**
|
||||
- Create controllers in `/src/modules/*/`
|
||||
- Implement business logic
|
||||
- Add validation schemas
|
||||
|
||||
2. **Create Workers**
|
||||
- PDF processing worker
|
||||
- Exercise generation worker
|
||||
- Notification worker
|
||||
|
||||
3. **Add Tests**
|
||||
- Unit tests
|
||||
- Integration tests
|
||||
- E2E tests
|
||||
|
||||
4. **Setup Docker**
|
||||
- Create Dockerfile
|
||||
- Configure docker-compose
|
||||
- Test container deployment
|
||||
|
||||
## Useful Commands
|
||||
|
||||
```bash
|
||||
# Check database health
|
||||
curl http://localhost:3001/health
|
||||
|
||||
# View logs
|
||||
tail -f logs/combined.log
|
||||
tail -f logs/error.log
|
||||
|
||||
# Database backup
|
||||
docker exec postgres pg_dump -U mathuser mathdb > backup.sql
|
||||
|
||||
# Restore database
|
||||
docker exec -T postgres psql -U mathuser mathdb < backup.sql
|
||||
```
|
||||
