This will talk through the installation and possible pitfalls when deploying node.js applications on AWS Elastic Beanstalk service.

const port = process.env.PORT || 8081;in your application.
eb init to create your application.
.elasticbeanstalkdirectory with a

eb create to create an environment for your app.
Use CodeCommitsince this is AWS Private Git repos. This step takes ~5 minutes.
