Hey, so this post is gonna be about a simple CRUD application made in ReactJS with NodeJS in the back-end, connecting to a Mongo Atlas Instance. This post and project aims at providing an overview of the project and the final product.

ContactBook

The application is a simple cloud based contact book. It supports the basic Create, Read Update and Delete operations and stores just a handful of details for each contact. The user must register and login to use the application based on which the contact information is stored. A cloud based contact book can be accessed from any device and from any location with just a login.

Additional Features

The application supports some additional features as experimentation on my end-

• Google Captcha for registration
• Responsive website that can be opened on mobile phones and tab as well.

• Development tools

For this application I used GitLab for version control and continuous integration. At the time of this project Github Actions was not fully developed to the current extent hence gitlab was the go to choice. With its CD pipelines I could easily deploy the application to preferred choice of nodes. The data for the application was directly stored in the Mongo. Mongo’s JS package called “Mongoose” was extremely handy eliminating the need for a back-end. With mongoose you can directly push/insert/retrieve data from any Mongo instance provided its connection string.

Deployment Tools

GitLab’s CI/CD pipeline was the go to choice for deployment to Heroku. At the time I was new to git and hence used the Heroku CLI to push code to the Heroku repo for publishing but later updated it to GitLabs CI/CD. Mongo instance for deployment was the Mongo Atlas, since its a scalable and cloud based deployment of Mongo with a free tier.
