Are you interested in building a full-stack web application using the MERN stack? Look no further than this step-by-step tutorial on building a MERN stack blog! In this tutorial, you’ll learn how to create a blog app using MongoDB, Express.js, React.js, and Node.js, along with best practices for coding and deploying your app.

Before we get started, make sure you’ve downloaded the project files from the zip file provided. Once you have the files, you’re ready to begin!


Run the command into the terminal to install node modules for frontend.

cd client
npm i

  1. Set up your development environment: The first step in building any web application is to set up your development environment. Make sure you have the latest versions of Node.js and MongoDB installed on your system.
  2. Create a new React app: Using the create-react-app command, create a new React app that will serve as the front-end of your blog.
  3. Set up your back-end: Next, create a new Express.js app that will serve as the back-end of your blog. Connect your app to a MongoDB database using the mongoose library.
  4. Create a RESTful API: Set up a RESTful API that will allow your front-end to communicate with your back-end. Define routes for creating, reading, updating, and deleting blog posts.
  5. Create your front-end components: Using React, create the components necessary to display and manage blog posts. These might include a list of posts, a form for creating new posts, and a form for editing existing posts.
  6. Connect your front-end to your back-end: Finally, connect your front-end to your back-end by making API requests from your React components.

Once you’ve completed these steps, you’ll have a fully functional MERN stack blog app! But don’t stop there – there are many ways you can customize and improve your app. Here are a few additional features you might consider adding:

  • User authentication: Allow users to sign up for an account and log in to create and manage their own blog posts.
  • Commenting system: Add a commenting system to allow users to discuss and respond to blog posts.
  • Search functionality: Implement search functionality to allow users to search for posts based on keywords or tags.

By following this tutorial, you’ll have a strong foundation for building your own MERN stack web applications. Don’t forget to check out the 17 tutorials provided for additional guidance and tips!
