Deploy NestJS Application On AWS


This would be a series of articles, in this article, we would talk about the deployment of the NESTJS application on AWS.

It will cover the following things,

Hands-on Lab - Deploy NestJS application on AWS

Open Visual Studio Code with the existing application, create a Procfile for the AWS pipelines to refer to, and see the file and its code –

web : npm run deploy

Once Procfile is created and the deploy command is mentioned there, then we need to create a deploy command in the package.json file, have a look at the below code

"deploy": "npm ci && npm run build && npm run start:prod"

Once, this is done, we would move to main.ts and define the environment variable as PORT and changes in the code, have a look below,

import { NestFactory } from'@nestjs/core';
import { AppModule } from'./app.module';
asyncfunctionbootstrap() {
    constapp = awaitNestFactory.create(AppModule);
    constport = process.env.PORT || 3000;

Now, execute the following to check if the APIs is working fine or not, below is the command, followed with response

npm run deploy

Now, create a GitHub repository named nest-api

Now, execute the following command to add, commit and push the API code into the following repository,

git remote add origin
git add.
git commit -m "Code changes"
git push origin master

Now, let’s move to AWS and open the portal using the URL – and then look for Amazon Elastic beanstalk and create a new beanstalk application using the steps

  • Name the application as nest-api
  • Choose the platform as nodejs
  • Choose a sample application and create the application

Then, search for a code pipeline and create a pipeline using the below steps

  • Name the pipeline as nest-api-pipeline, choose a new service role

Click on next, connect with our GitHub account using the GitHub credentials, select the repository and the branch, click on skip

Skip the build stage and then add the deploy stage, select AWS elastic beanstalk, select application name and environment (default), click on next

Review the pipeline and create the pipeline, see the execution

Go back to the Visual Studio Code and do some of the below changes in the tag.controller.ts and push the code using the below command

git push origin master

It would trigger the pipeline again, and execute the web URL again to check out the results –
