230### Database Patterns
231- Run migrations on startup or comment out for performance
232- Change table names when modifying schemas rather than altering
7 out: "./backend/drizzle",
8 dbCredentials: {
9 url: process.env.DATABASE_URL!,
10 },
11});
9- The **client-side entrypoint** is `/frontend/index.html`, which in turn imports `/frontend/index.tsx`, which in turn imports the React app from `/frontend/components/App.tsx`.
