## Usage Guide
|
||||
|
||||
### Development (SQLite - Default)
|
||||
|
||||
```bash
|
||||
# No setup needed, works immediately
|
||||
pnpm run dev
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```
|
||||
✅ SQLite database initialized
|
||||
✅ Database initialized (type: sqlite)
|
||||
✅ Bot logged in
|
||||
✅ Message capture handlers registered
|
||||
✅ AI analysis worker started
|
||||
✅ WebSocket server listening on port 3000
|
||||
```
|
||||
|
||||
### Production (PostgreSQL)
|
||||
|
||||
```bash
|
||||
# 1. Update .env
|
||||
DATABASE_TYPE=postgres
|
||||
DATABASE_URL=postgresql://user:password@host:5432/database
|
||||
|
||||
# 2. Run migrations (programmatic - more reliable)
|
||||
pnpm run db:migrate:programmatic
|
||||
|
||||
# 3. Start bot
|
||||
pnpm run dev
|
||||
```
|
||||
|
||||
### Database Management Commands
|
||||
|
||||
```bash
|
||||
# Generate migrations from schema changes
|
||||
pnpm run db:generate
|
||||
|
||||
# Apply pending migrations (Drizzle Kit CLI)
|
||||
pnpm run db:migrate
|
||||
|
||||
# Apply pending migrations (Programmatic - recommended for PostgreSQL)
|
||||
pnpm run db:migrate:programmatic
|
||||
|
||||
# Open Drizzle Studio UI for visual data management
|
||||
pnpm run db:studio
|
||||
```

## Troubleshooting
|
||||
|
||||
### PostgreSQL Connection Timeout
|
||||
|
||||
**Problem:** `pnpm run db:migrate` times out when connecting to PostgreSQL
|
||||
|
||||
**Solutions:**
|
||||
1. Use programmatic migration: `pnpm run db:migrate:programmatic`
|
||||
2. Verify network connectivity to database host
|
||||
3. Check firewall/security group allows your IP
|
||||
4. Verify DATABASE_URL in .env is correct
|
||||
5. Use SQLite for development (default)
|
||||
|
||||
### Table Already Exists Error
|
||||
|
||||
**Problem:** Migration fails with "table X already exists"
|
||||
|
||||
**Solution:** This is expected when running migrations on an already-initialized database. The tables are already created and migrations are tracked in `__drizzle_migrations` table.
|
||||
|
||||
### Missing Environment Variables
|
||||
|
||||
**Problem:** Config validation fails for DISCORD_TOKEN
|
||||
|
||||
**Solution:** Ensure `.env` file exists in project root with all required variables
|
||||
|
||||

|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Development)
|
||||
- ✅ Bot works with SQLite (no action needed)
|
||||
- ✅ All tests passing
|
||||
- ✅ Ready for feature development
|
||||
|
||||
### Short Term (Production)
|
||||
1. Configure PostgreSQL connection in `.env`
|
||||
2. Run `pnpm run db:migrate:programmatic` to create schema
|
||||
3. Deploy bot with PostgreSQL
|
||||
|
||||
### Long Term (Maintenance)
|
||||
1. Update `src/database/schema.ts` for schema changes
|
||||
2. Run `pnpm run db:generate` to create migrations
|
||||
3. Use `pnpm run db:studio` for data management
|
||||
4. Monitor migration history in `__drizzle_migrations` table
