Backend — Virtual CV API

Lightweight backend for managing virtual CV data. Built with a focus on performance, simplicity, and full runtime control.

Stack

• Node.js (ESM)
• TypeScript
• Fastify
• PostgreSQL (pg)
• Prisma
• Zod

Scripts

npm run dev      # Run in development (watch mode)
npm run build    # Build for production (BE VERY CAREFUL! CREATE A BACKUP BEFORE BUILDING)
npm run start    # Run built app
npm run lint     # Lint and fix code

Project Structure

src/
├── index.ts
├── db/
└── modules/

Execution Flow

Development: tsx runs TypeScript directly with watch mode
Build: tsc compiles code into /dist and generates Prisma client
Production: runs compiled JavaScript only (no TypeScript overhead)

Database

PostgreSQL via pg + Prisma Client
Direct SQL possible for performance-critical paths
Full control over query execution

API Example

fastify.get("/users", async () => {
  const result = await prisma.user.findMany({
    select: {
      id: true,
      email: true
    }
  });

  return result;
});

Principles

• Minimal dependencies
• Explicit logic over abstractions
• Compile-time over runtime
• Performance-first design
