Demo NodeJs App with ExpressJs, MegaLinter and Terraform

Instructions

Preface

This application runs on Node.js with ExpressJs framework, Nunjucks as template engine.

Coding standards and style are preserved by using multiple linters which are executed in CI or locally via MegaLinter

Tests are executed no ensure that the functionality is working even though here we don't have too many tests since this is for demo purposes. They are executed via Jest test framework.

It uses AWS cloud to deploy the application on which the resources are provisioned by using Terraform infrastructure as code.

Terraform needs to be executed manually before since it's not part of the CI/CD.

Yarn is used as a package manager.
