This project uses PostgreSQL with Prisma ORM.

2. see the env.ts file in apps/api to get sample env variables

3. Update your apps/api/.env file with your PostgreSQL connection details.

4. Generate the Prisma client:

pnpm db:generate

5. Optionally seed the db:

pnpm dlx prisma db seed

if you get errors, then either skip this step or use bun or deno to run seed.ts:

bunx run apps/api/prisma/seed.ts

6. Apply migrations:

pnpm run db:migrate

Then, run the development server:

pnpm dev

Open http://localhost:3001 in your browser to see the web application.
