The token is composed of a header, a payload, and a signature. A JWT is a JSON response that is defined in RFC 7519 as a safe way to represent a set of information between two parties. JSON Web Tokens are an open, industry-standard RFC 7519 method for representing claims securely between two parties. It just wasn’t in the scope of this article. I am implementing the JWT authentication on the frontend using React, and here it goes.Īlso, please note that I haven’t added any MongoDB part, yet I referred to it as a MERN stack application - sorry. The authentication mechanism has been built on JWT on the. We are building a React frontend that talks to a. Our client wants to be sassy and found out that the trending tech in authentication is JWT (JSON Web Token), and the pressure soon built up in using it for all authentication purposes.īeing a React person, I don’t mind working on it and learning a new tech, but yeah - that’s why I am here writing my experience on this. My greenfield project requires the usual song and dance: authentication. Creating a full-stack MERN app using JWT authentication: Part 1 Next you need to make sure that Bootstrap's CSS file is imported in App.js by adding the following line of code: import " bootstrap/dist/css/ " įurthermore you need to get rid of most of the default code which is contained in App.Praveen Kumar Follow Blogger, MVP, Web Developer, Computer Software and UX Architect. Inside the project folder execute the following command to add the library: This is needed because we'll be making use of Bootstrap's CSS classes to build our user interface. Next, we need to add the Bootstrap framework to our project. Now you should be able to see the following result in the browser: [ Adding Bootstrap To The React Project Change into the newly created folder:Īnd start the development web server by running the following command: Inside this folder you'll find the default React project template with all dependencies installed. Just execute the following command:Įxecuting this command creates a new project directory mern-todo-app. What's great about create-react-app is that this script can be executed by using the npx command without the need to install it first on your system. In the next step we're creating the initial React project by using the create-react-app script. This will print out the Node.js version which is installed on your system. You can check if Node.js is installed on your system by typing in: If that is not the case please go to first and follow the installation instructions for your platform. Setting Up The React Applicationįor this tutorial it is assumed that Node.js is installed on your system. In the next part we're going to continue with implementing the Node.js / Express server. In this first part of this series we're going to complete the setup the React project for building the front-end part of the MERN stack sample application. By using this example it's possible to demonstrate how to build a CRUD (Create, Read, Update, and Delete) application from scratch by using the MERN stack! The application we'll be building in this tutorial series is a simple To-Do application. The only difference here is that the MEAN stack is making use of Angular to build the front-end web application and the MERN stack is using React instead. The MERN stack is very similar to the popular MEAN stack.
