How to deploy NestJS to AWS

Deploy a NestJS server on ECS Fargate behind an Application Load Balancer.

Prerequisites

A Git repository containing your application and its production build command.
A Ravion account with your AWS account connected. Start free at Ravion signup.
The Ravion CLI installed and authenticated. See CLI installation.

The examples use my-org/my-app as a placeholder. Replace it with your repository before applying the config.

Set up this NestJS app for Ravion ECS hosting.

Configure the deployment

The Nest CLI production build writes JavaScript to dist, with the standard starter entry at dist/main.js. This example uses Railpack for the build. Use build_source: dockerfile instead when you need a custom Dockerfile.

ravion.yaml

project:
  givenId: nestjs-app
  name: NestJS app
environments:
  - givenId: production
    name: Production
    moduleInstances:
      - givenId: network
        name: Network
        type: rvn-aws-network
        version: 1.0.0
        input:
          aws_account_id: ravion-prod
          aws_region: us-east-1
          name: nestjs-production
      - givenId: cluster
        name: ECS cluster
        type: rvn-ecs-cluster
        version: 1.0.0
        input:
          network:
            moduleGivenIdRef: network
          name: nestjs-production
      - givenId: web
        name: NestJS web service
        type: rvn-ecs-web
        version: 1.0.0
        input:
          cluster:
            moduleGivenIdRef: cluster
          name: nestjs-production-web
          build_source: railpack
          source_repo: my-org/my-nestjs-app
          railpack_build_cmd: npm run build
          railpack_start_cmd: node dist/main.js
          container_port: 3000
          fargate_size:
            vcpu: 0.5
            memory_gb: 1

Set the application to listen on 0.0.0.0 and use port 3000, or read PORT from the environment. Add a health endpoint and change health_check_path when your app does not serve /.

Apply and connect your domain

ravion project create --given-id nestjs-app --name "NestJS app"
ravion project config apply nestjs-app --file ravion.yaml --dry-run
ravion project config apply nestjs-app --file ravion.yaml

Follow custom domains to connect your domain to the Application Load Balancer.

Custom domains

Point a domain at your deployed service and manage its certificate.

Project config

Preview and apply Ravion configuration from source control.

Pipelines

Add approvals, migrations, and deployment automation.

Logs and metrics

Inspect deploy output and production health in Ravion.
