# Instagram Event Scraper API
2+
3+
Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the info here.
4+
5+
This is a full-stack web application consisting of a Django REST API backend and a React + TypeScript frontend for scraping and displaying Instagram events from university clubs.
6+
7+
## Working Effectively
8+
9+
### Bootstrap Environment
10+
- Run these commands in sequence to set up the development environment:
11+
- Backend setup:
12+
```bash
13+
cd backend
14+
pip install -r requirements.txt # Takes ~22 seconds. NEVER CANCEL.
15+
export USE_SQLITE=1
16+
python manage.py migrate # Takes <1 second
17+
python manage.py runserver 8000 # Starts immediately
18+
```
19+
- Frontend setup:
20+
```bash
21+
cd frontend
22+
npm install # Takes ~12 seconds. NEVER CANCEL.
23+
npm run build # Takes ~9 seconds. NEVER CANCEL. Set timeout to 30+ seconds.
24+
npm run dev # Starts immediately on port 5173
25+
```
26+
27+
### Development Database Configuration
28+
- **CRITICAL**: Always set `export USE_SQLITE=1` before running Django commands for local development
29+
- Without this environment variable, Django will try to connect to PostgreSQL and fail
30+
- The production environment uses PostgreSQL via Supabase, but local development uses SQLite
31+
32+
### Build and Test Commands
33+
- Backend:
34+
- `python manage.py check` - Django configuration check (<1 second)
35+
- `python manage.py test` - Run Django tests (currently no tests defined)
36+
- `python manage.py migrate` - Apply database migrations (<1 second)
37+
- Frontend:
38+
- `npm run build` - Production build (~9 seconds)
39+
- `npm run lint` - ESLint check (~3 seconds, may show warnings/errors)
40+
- `npm run dev` - Development server (starts immediately)
41+
- `npm run preview` - Preview production build
42+
43+
### Running Applications
44+
- Backend API server:
45+
```bash
46+
cd backend
47+
export USE_SQLITE=1
48+
python manage.py runserver 8000
49+
```
50+
Available at http://localhost:8000/ with endpoints:
51+
- `GET /` - API information
52+
- `GET /health/` - Health check
53+
- `GET /events/` - Get all events
54+
- `GET /clubs/` - Get all clubs
55+
56+
- Frontend development server:
57+
```bash
58+
cd frontend
59+
npm run dev
60+
```
61+
Available at http://localhost:5173/
62+
63+
## Validation
64+
65+
### Always Test These Scenarios After Making Changes
66+
1. **Backend API validation**:
67+
- Start backend server with SQLite
68+
- Test endpoints: `curl http://localhost:8000/health/` should return `{"status":"healthy","message":"Server is running"}`
69+
- Test API info: `curl http://localhost:8000/` should return JSON with endpoints info
70+
- Test events endpoint: `curl http://localhost:8000/events/` should return events list (may be empty)
71+
72+
2. **Frontend validation**:
73+
- Build frontend successfully with `npm run build`
74+
- Start development server with `npm run dev`
75+
- Verify server starts on port 5173 with no errors
76+
- Check that `curl -I http://localhost:5173/` returns HTTP 200
77+
78+
3. **Full-stack integration**:
79+
- Run both backend (port 8000) and frontend (port 5173) simultaneously
80+
- Frontend should connect to backend API for data
81+
82+
### Linting and Code Quality
83+
- **Backend**: Use Django's built-in checks: `python manage.py check --deploy`
84+
- **Frontend**: Always run `npm run lint` before committing (may show existing warnings, focus on new ones)
85+
- Frontend linting currently shows some pre-existing issues - do not spend time fixing unless directly related to your changes
86+
87+
## Common Issues and Workarounds
88+
89+
### Database Connection Issues
90+
- **Problem**: `django.db.utils.OperationalError: could not translate host name "your-project.supabase.co"`
91+
- **Solution**: Always set `export USE_SQLITE=1` environment variable for local development
92+
93+
### Secret Key Issues
94+
- **Problem**: `ImproperlyConfigured: The SECRET_KEY setting must not be empty`
95+
- **Solution**: Already fixed in settings.py with a default development key
96+
97+
### Static Files Warning
98+
- **Problem**: `The directory '/path/to/backend/static' in the STATICFILES_DIRS setting does not exist`
99+
- **Solution**: Run `mkdir -p backend/static` (already resolved)
100+
101+
### Docker Build Issues
102+
- **Problem**: Docker build fails with SSL certificate errors in restricted environments
103+
- **Solution**: Do not attempt Docker builds in restricted environments. Use local Python environment instead.
104+
105+
### Frontend ESLint Errors
106+
- **Problem**: ESLint shows errors in existing code (currently 6 errors, 1 warning)
107+
- **Solution**: Focus only on new errors introduced by your changes. Existing issues in EventsCalendar.tsx, button.tsx, and dateUtils.ts are pre-existing.
108+
109+

145+
## Dependencies and Versions
146+
147+
### Backend Requirements
148+
- Django 4.2.7
149+
- Django REST Framework 3.14.0
150+
- PostgreSQL support (psycopg2-binary)
151+
- Data processing: pandas, numpy
152+
- Scraping: instaloader (custom build), requests, beautifulsoup4
153+
- AI: openai
154+
- Production: gunicorn, whitenoise
155+
156+
### Frontend Dependencies
157+
- React 19.1.0 with TypeScript
158+
- Build tool: Vite 7.1.3
159+
- Styling: TailwindCSS 4.1.11
160+
- UI components: Radix UI components
161+
- State management: TanStack Query
162+
- Development: ESLint, TypeScript ESLint
163+
164+
## CI/CD Integration
165+
166+
### GitHub Actions Workflow (`.github/workflows/instagram_feed.yml`)
167+
- Runs daily Instagram scraping job
168+
- Requires external secrets (Instagram credentials, OpenAI API key, database URL)
169+
- Uses Python 3.11 runtime
170+
- Caches pip dependencies for faster builds
171+
- Uploads scraping logs as artifacts
172+
173+
### Important Notes
174+
- The scraping workflow requires external services and credentials not available in local development
175+
- Focus development on the API and frontend components rather than scraping functionality
176+
- The workflow is configured for production environment with real Instagram data
177+
178+
## Timing Expectations and Timeouts
179+
180+
- **pip install**: 22 seconds, set timeout to 60+ seconds, NEVER CANCEL
181+
- **npm install**: 12 seconds, set timeout to 30+ seconds, NEVER CANCEL
182+
- **npm run build**: 9 seconds, set timeout to 30+ seconds, NEVER CANCEL
183+
- **Database migrations**: <1 second
184+
- **Server startup**: Both backend and frontend start immediately (<5 seconds)
185+
- **ESLint**: 3 seconds
186+
187+

214+
```
215+
216+
## Manual Validation Scenarios
217+
218+
After making any changes, always complete these validation scenarios:
219+
220+
1. **Complete Development Setup Test**:
221+
- Start fresh terminal
222+
- Follow bootstrap instructions exactly
223+
- Verify both servers start without errors
224+
- Test all API endpoints respond correctly
225+
226+
2. **Build Pipeline Test**:
227+
- Clean build: `rm -rf frontend/dist backend/db.sqlite3`
228+
- Full rebuild following bootstrap instructions
229+
- Verify no new linting errors beyond existing 7 issues
230+
- Confirm both development servers start successfully
231+
232+
3. **API Functionality Test**:
233+
- Start backend with SQLite
234+
- Test each endpoint: `/`, `/health/`, `/events/`, `/clubs/`
235+
- Verify JSON responses are well-formed
236+
- Check database operations work (migrations, etc.)
237+
238+
4. **Cross-Platform Compatibility**:
239+
- Instructions tested on Linux with Python 3.12 and Node.js 20.19
240+
- SQLite configuration ensures database portability
241+
- No external services required for basic development
