React Redux: Token Authentication example with JWT & Axios

In this tutorial, were gonna build a React + Redux Application for Token Authentication example with JWT, LocalStorage, React Router, Axios and Bootstrap. I will show you:

• JWT Authentication Flow for User Signup & User Login
• Project Structure for React Redux JWT Authentication, LocalStorage, Router, Axios
• Working with Redux Actions, Reducers, Store for Application state
• 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 Spring Boot backend that works well with this React Client:

• one working with MySQL/PostgreSQL
• and one working with MongoDB

Overview of React Redux 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 Users roles (admin, moderator, user), Navigation Bar changes its items automatically.

Here are the screenshots:
Signup Page:

Signup failed:

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:

Check State in Redux using redux-devtools-extension:

User Registration and User Login Flow

For JWT Authentication, were 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:

• Spring Boot JWT Authentication with Spring Security, MySQL
• Spring Boot JWT Authentication with Spring Security, PostgreSQL
• Spring Boot JWT Authentication with Spring Security, MongoDB
• Node.js JWT Authentication & Authorization with MySQL
• Node.js JWT Authentication & Authorization with MongoDB
• Node.js JWT Authentication & Authorization with PostgreSQL
