Dockerization

Dockerize NestJS: TypeScript, Prisma, and Production-Grade Containers

NestJS adds TypeScript compilation, decorators, and often Prisma or TypeORM to the Node.js containerization equation. We handle the full build chain — compiling TypeScript, generating Prisma client, and producing a slim runtime image that ships only the compiled JavaScript and production dependencies.

We implement, you ship. Async, documented, done in days.

Why Dockerize NestJS

NestJS requires a TypeScript build step before deployment, and many NestJS apps depend on Prisma, which needs prisma generate at build time to create the query engine binary. Missing this step means cryptic runtime errors about missing Prisma client.

A proper Docker setup compiles TypeScript, generates Prisma client with the correct binary target (linux-musl-openssl-3.0.x for Alpine), prunes dev dependencies, and ships only the dist/ output with production node_modules.

Our Docker Implementation for NestJS

Three-stage Dockerfile for NestJS + Prisma:

  • Deps stage: FROM node:20-alpine AS deps — runs npm ci to install all dependencies. If using Prisma, runs npx prisma generate here so the query engine binary is built for the correct platform.
  • Build stage: FROM node:20-alpine AS builder — copies deps and source, runs npm run build (which executes nest build or tsc). Then runs npm prune --omit=dev to remove dev dependencies.
  • Runner stage: FROM node:20-alpine — copies dist/, production node_modules/, prisma/ schema, and generated client. Runs with dumb-init as PID 1, non-root user, and NODE_ENV=production.

Compose file includes the NestJS app, Postgres, and Redis. Health check hits /api/health. The dev override mounts source with hot-reload via nest start --watch.
