Authentication & Authorization with React.js example

#react #webdev #node #javascript

In this tutorial, we’re gonna build a React JWT Authentication example with LocalStorage, React Router, Axios and Bootstrap (without Redux). I will show you:

JWT Authentication Flow for User Signup & User Login
Project Structure for React JWT Authentication (without Redux) with LocalStorage, React Router & Axios
Creating React Components with Form Validation
React Components for accessing protected Resources (Authorization)
Dynamic Navigation Bar in React App

Inside tutorial, you can also find Nodejs or Spring Boot backend that works well with this React Client:

one working with MySQL/PostgreSQL
and one working with MongoDB

Overview of React JWT Authentication example

We will build a React application in that:

There are Login/Logout, Signup pages.
Form data will be validated by front-end before being sent to back-end.
Depending on User’s roles (admin, moderator, user), Navigation Bar changes its items automatically.

Here are the screenshots:
– Signup Page:

– Form Validation Support:

– Login Page:

– Profile Page (for successful Login):

– For Moderator account login, the navigation bar will change by authorities:

– Check Browser Local Storage:

User Registration and User Login Flow

For JWT Authentication, we’re gonna call 2 endpoints:

POST api/auth/signup for User Registration
POST api/auth/signin for User Login
The following flow shows you an overview of Requests and Responses that React Client will make or receive. This React Client must add a JWT to HTTP Header before sending request to protected resources.

You can find step by step to implement these back-end servers in following tutorial:
