Deploy a NestJS app on Enzonic

Deploy builds a NestJS app with nest build and starts node dist/main.js directly (nest start would need the CLI and recompile at runtime). The app runs as a long-lived server, so WebSockets, queues and scheduled jobs inside it keep working.

Deploy NestJS Docs

At a glance

What Enzonic Deploy does with a NestJS project when you connect it. You can override any of it in the project settings.

Language: TypeScript
Detected from: @nestjs/core in dependencies
Build command: nest build
Output: dist
Runs as: Server

Dependencies install with the package manager your lockfile names: npm ci, pnpm install --frozen-lockfile, yarn install --immutable (Berry) or --frozen-lockfile, or bun install --frozen-lockfile. Node.js 18, 20, 22 and 24 are available. Deploy reads engines.node in package.json, then .nvmrc or .node-version, and uses Node.js 22 when nothing pins a version.

How it runs

Server
Always: node dist/main.js, listening on the PORT variable.

Deploy NestJS step by step

1Make main.ts listen on process.env.PORT and 0.0.0.0.
2Connect the repository and deploy.

src/main.ts

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(process.env.PORT ?? 3000, '0.0.0.0');
}
bootstrap();

Connect a database to NestJS

Create a database on Enzonic Databases (or from the project's settings) and its connection string is added to the project's environment variables. This example uses PostgreSQL.

src/app.module.ts

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';

@Module({
  imports: [
    TypeOrmModule.forRoot({
      type: 'postgres',
      url: process.env.DATABASE_URL,
      ssl: true,
      autoLoadEntities: true,
    }),
  ],
})
export class AppModule {}

Postgres projects get two variables: DATABASE_URL through the connection pooler for the app, and DATABASE_URL_UNPOOLED for migrations.

Things to know

A server that listens on a fixed port or on localhost only is not reachable: always use PORT and 0.0.0.0.
On Free, servers sleep after 15 idle minutes; in-process cron jobs pause with them. Paid plans keep servers always on.

Plan limits that matter here

From the live plan data. Every plan includes previews for each branch, instant rollback, environment variables and logs.

Plan limits that matter for NestJS
Limit	Free	Pro
Build minutes	3,000/mo, 1 concurrent	10,000/mo, 3 concurrent
Servers	1 instance, 512 MB, sleeps after 15 min idle	3 always-on, 2 GB
Bandwidth	150 GB/mo	2 TB/mo
