Deploying a nodejs application in elastic beanstalk

Deploying a nodejs application in AWS elastic beanstalk

Elastic Beanstalk is a fully managed service by Amazon Web Services (AWS) that makes it easy to deploy and scale applications in the cloud. In this tutorial, I'll walk through the process of deploying a Node.js application to Elastic Beanstalk.

Prerequisites

  • AWS account
  • AWS CLI
  • Node.js

Initialize your project

  • Install the AWS CLI using the command npm install -g aws-cli
  • Create a directory for your project and navigate to it using the command mkdir my-project && cd my-project
  • Initialize your project using the command npm init -y
eb init --profile [aws-sdk named profile]
  • Follow the steps to select your region, application name, and environment name.

Create an environment

  • Create a new environment using the command eb create --profile [aws-sdk named profile]
  • Follow the prompts to select your environment type, platform, and instance type.

Deploy the application

  • Build your application using the command npm run build
  • Upload the application to Elastic Beanstalk using the command eb deploy --profile [aws-sdk named profile]

Access your application

  • eb open to open the application in a web browser

Behind the scenes

  • The EB CLI uses Git to create a source bundle of your application code.
  • The source bundle is uploaded to an S3 bucket specified in your Elastic Beanstalk configuration
  • Elastic Beanstalk retrieves the source bundle from the S3 bucket.
  • Elastic Beanstalk launches a new instances to handle the deployment.
  • Elastic Beanstalk deploys the source bundle to the new instances.
  • The old instances are terminated and the deployment is complete.

Congratulations! You successfully deployed your Node.js application to Elastic Beanstalk using the EB CLI.
