Dyolink — Backend (NestJS)

Prerequisites

• Node.js 20+ and npm
• PostgreSQL reachable from your machine (local or remote)

First-time setup

1. Clone the monorepo and go to the backend app:

   git clone <repository-url> dyolink
   cd dyolink/backend
   

2. Install dependencies

   npm install
   

3. Environment

   Copy .env.example to .env and set at least:

   • DATABASE_URL — PostgreSQL connection string for your dev database
   • JWT_SECRET — strong secret for signing tokens
     Do not commit .env.

4. Database URL for local dev

   Point DATABASE_URL at a database you created in Postgres (create an empty DB first if needed).

5. Generate Prisma Client

   npm run prisma:generate
   

6. Apply migrations (creates/updates tables to match prisma/schema.prisma)

   npm run prisma:migrate
   

   This runs prisma migrate dev. Use it during development when the schema changes.

7. Seed (optional — sample data / bootstrap)

   npm run prisma:seed
   

Run (development)

npm run start:dev

API listens on http://localhost:3000 by default (PORT in .env).

If the frontend runs on another origin (e.g. http://localhost:3001), set CORS_ORIGIN in .env to that URL.

After pulling latest main

git pull
npm install
npm run prisma:generate
npm run prisma:migrate

If teammates added migrations, step 4 applies them. Resolve migration conflicts locally before pushing.

Useful commands

Command	Purpose
npm run prisma:generate	Regenerate client after schema.prisma changes
npm run prisma:migrate	Dev migrations (migrate dev)
npm run prisma:deploy	Production-style apply (migrate deploy) — e.g. CI/containers
npm run build	Compile Nest app
npm run start:prod	Run compiled app (node dist/main)
