React JWT Authentication (without Redux) example

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

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.

Set port

.env

PORT=8081

Note:

Open src/services/auth-header.js and modify return statement for appropriate back-end (found in the tutorial).

export default function authHeader() {
  const user = JSON.parse(localStorage.getItem('user'));

  if (user && user.accessToken) {
    // return { Authorization: 'Bearer ' + user.accessToken }; // for Spring Boot back-end
    return { 'x-access-token': user.accessToken };             // for Node.js Express back-end
  } else {
    return {};
  }
}

Project setup

In the project directory, you can run:

npm install
# or
yarn install

or

Compiles and hot-reloads for development

npm start
# or
yarn start

Open http://localhost:8081 to view it in the browser.

The page will reload if you make edits.
