🌐 MERN stack 2.0 - MongoDB, Express, React/Redux, Node

Product Analysis: MERN Stack


MERN is a fullstack implementation based on MongoDB, Expressjs, React/Redux, and Nodejs. It is a JavaScript/Node-based framework for fullstack web development. The MERN stack allows for seamless integration between the front-end and back-end of web applications.


  • MongoDB: A NoSQL database that provides scalable storage for data in a JSON-like format.
  • Expressjs: A web application framework for building APIs and handling server-side applications.
  • React/Redux: A JavaScript library for building user interfaces and managing state.
  • Nodejs: A JavaScript runtime that allows for server-side execution of JavaScript code.
  • Fullstack Web Development: MERN offers a complete solution for building web applications, from the database to the front-end UI.
  • JWT Authentication: MERN supports JSON Web Token (JWT) authentication, allowing users to securely access protected API endpoints.
  • Client-Server Communication: MERN enables seamless communication between the client-side and server-side components of a web application.
  • Deployment to Heroku: MERN provides a guide for deploying the server to the Heroku cloud platform.


To install and run the MERN stack on your machine, follow these steps:

  1. Prerequisites:

    • MongoDB
    • Node ^10.0.0
    • npm
  2. Clone or download the project structure.

  3. Client-side usage (PORT: 3000):

    • Run npm install to install the required dependencies.
    • Make sure the client and server run concurrently in different terminal sessions to enable communication between them.
  4. Server-side usage (PORT: 8000):

    • Run npm install to install the required dependencies.
    • Prepare your secret by adding a JWT_SECRET in the .env file to connect to MongoDB.
    • Run the script at the first level.
  5. Deploy Server to Heroku:

    • After creating a Heroku app, update the file of client/ if using webpack, or client/.env.production if using parcel.
  6. Dependencies (tech-stacks):

    • Client-side: axios: ^0.15.3, babel-preset-stage-1: ^6.1.18, lodash: ^3.10.1, react: ^16.2.0, react-dom: ^16.2.0, react-redux: ^4.0.0, react-router-dom: ^4.2.2, redux: ^3.7.2, redux-thunk: ^2.1.0.
    • Server-side: bcrypt-nodejs: ^0.0.3, body-parser: ^1.15.2, cors: ^2.8.1, dotenv: ^2.0.0, express: ^4.14.0, jwt-simple: ^0.5.1, mongoose: ^4.7.4, morgan: ^1.7.0.


MERN stack is a powerful and efficient framework for fullstack web development. It combines MongoDB, Expressjs, React/Redux, and Nodejs to provide a seamless integration between the front-end and back-end of web applications. With features such as JWT authentication and client-server communication, MERN stack simplifies the development process and enables the creation of robust, scalable, and secure web applications.


Express.js is a simple Node.js framework for single, multi-page, and hybrid web applications.


React is a widely used JavaScript library for building user interfaces and single-page applications. It follows a component-based architecture and uses a virtual DOM to efficiently update and render UI components

Fullstack Boilerplates

A fullstack boilerplate provides a starter application that includes both frontend and backend. It should include database, auth, payments, user roles and other backend services to build a fully featured saas or webapps.


ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.


Redux is a state management library for JavaScript apps that provides a predictable and centralized way to manage application state. It enables developers to write actions and reducers that update the state in response to user interactions, server responses, and other events, and can be used with a variety of front-end frameworks and back-end technologies.
