Reactjs JWT Token Authentication Example

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. So in the tutorial, I introduce how to implement an application “Reactjs JWT token Authentication Example” with details step by step and 100% running sourcecode.

– I give you an Epic of the application, a fullstack excutive flow from frontend to backend with overall architecture diagram.
– I give you a layer diagram of Reactjs JWT Application.
– I give you an implementatin of security backend sourcecode (SpringBoot + Nodejs JWT RestAPIs).
– I guide you step by step how to develop a Reactjs JWT Authentication application.
– Finally, I do an integrative testing from Reactjs JWT Authentication application to Backend Security RestAPIs

For the Reactjs JWT Authentication tutorial, we have 2 projects:
– Backend project (using SpringBoot or Nodejs Express) provides secured RestAPIs with JWT token.
– Reactjs project will request RestAPIs from Backend system with the JWT Token Authentication implementation.

JWT Authentication Sequence Diagram

The diagram below show how our system handles User Registration and User Login processes:

JWT Authentication Sequence Diagram

  1. User Registration Phase:
    – User uses a React.js register form to post user’s info (name, username, email, role, password) to Backend API /api/auth/signup.
    – Backend will check the existing users in database and save user’s signup info to database. Finally, It will return a message (successfully or fail) to

  2. User Login Phase:
    – User posts user/password to signin to Backend RestAPI /api/auth/signin.
    – Backend will check the username/password, if it is right, Backend will create and JWT string with secret then return it to Reactjs client.

After signin, user can request secured resources from backend server by adding the JWT token in Authorization Header. For each request, backend will check the JWT signature and then returns back the resources based on user’s registered authorities.

Reactjs JWT Authentication Layer Diagram Overview

Reactjs JWT Authentication Layer Diagram Overview

Reactjs JWT Authentication would be built with 5 main kind blocks:

  • Reactjs Router is a standard library for routing in React. It enables the navigation among views of various components in a React Application, allows changing the browser URL, and keeps the UI in sync with the URL.
  • Reactjs Components let you split the UI into independent, reusable pieces, and think about each piece in isolation.
  • Reactjs Service is a bridge between Reactjs Component and Backend Server, it is used to do technical logic with Backend Server (using Ajax Engine to fetch data from Backend, or using Local Storage to save user login data) and returned a response data to React.js Components
  • Local Storage allow to save key/value pairs in a web browser. It is a place to save the login user’s info.
  • Axios – (an Ajax Engine) is a promise-based HTTP client for the browser and Node. js. Axios makes it easy to send asynchronous HTTP requests to REST endpoints and perform CRUD operations.

We create a Reactjs JWT Authentication project as below:

JWT Role Based Authorization with Spring Boot and Angular 9 (Spring Boot Login Example)

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. So in tutorial ‘JWT Role Based Authorization with Spring Boot and Angular 9 (Spring Boot Login Example)’, I guide you very clearly how to implement full stack example to demonstrade an jwt token based authentication flow from frontend Angular 9 to backend: SpringBoot and MySQL.

– I give you an Epic of the application, a fullstack excutive flow from frontend – Angular 9 to backend – SpringBoot with overall architecture diagram.
– I give you an architecture diagram of SpringBoot security backend.
– I give you a working flow diagram of Angular 9 JWT Application.
– I guide you step by step how to develop a Backend SpringBoot secured RestAPIs with JWT token.
– I guide you step by step how to develop an Angular 9 JWT Token Authentication application.
– Finally, I do an integrative testing from Angular 9 JWT Authentication application to SpringBoot Backend Security RestAPIs.

Angular Spring Boot JWT Authentication example

We will build an application, from frontend (Angular) to backend (Spring Boot), which allows users to register, login account. This application is secured with JWT (JSON Web Token) authentication and Spring Security. Then, depending on the role of current User (user, pm or admin), this system accepts what he can access:

Angular-9-Login-Form

Angular 9 Register Form

Angular 9 Home Page of a User with USER_ROLE

Angular 9 Content Page of a User with USER_ROLE

The diagram below show how our system handles User Registration and User Login processes:

Angular 9 Spring Boot Security Jwt Token Authentication Work Process Diagram

SPRING BOOT BACK-END WITH SPRING SECURITY

This is diagram for SpringBoot Token based authentication Security/JWT classes that are separated into 3 layers:
– HTTP
– Spring Security
– REST API

Spring Boot Security Jwt Token Authentication Architecture Diagram Back End Server

– SecurityContextHolder provides access to the SecurityContext.
– SecurityContext holds the Authentication and possibly request-specific security information.
– Authentication represents the principal which includes GrantedAuthority that reflects the application-wide permissions granted to a principal.
– UserDetails contains necessary information to build an Authentication object from DAOs or other source of security data.
– UserDetailsService helps to create a UserDetails from a String-based username and is usually used by AuthenticationProvider.
– JwtAuthTokenFilter (extends OncePerRequestFilter) pre-processes HTTP request, from Token, create Authentication and populate it to SecurityContext.
– JwtProvider validates, parses token String or generates token String from UserDetails.
– UsernamePasswordAuthenticationToken gets username/password from login Request and combines into an instance of Authentication interface.
– AuthenticationManager uses DaoAuthenticationProvider (with help of UserDetailsService & PasswordEncoder) to validate instance of UsernamePasswordAuthenticationToken, then returns a fully populated Authentication instance on successful authentication.
– SecurityContext is established by calling SecurityContextHolder.getContext().setAuthentication(…​) with returned authentication object above.
– AuthenticationEntryPoint handles AuthenticationException.
– Access to Restful API is protected by HTTPSecurity and authorized with Method Security Expressions.

ANGULAR FRONT-END WITH INTERCEPTOR

In the tutorial, “Angular 9 + Spring Boot JWT Token Based Authentication Example”, we need the Angular HTTP Interceptor to add JWT Token Based for Security authentication:

Angular 9 Jwt Token Workflow Diagram

– app.component is the parent component that contains routerLink and router-outlet for routing. It also has an authority variable as the condition for displaying items on navigation bar.
– user.component, pm.component, admin.component correspond to Angular Components for User Board, PM Board, Admin Board. Each Board uses user.service to access authority data.
– register.component contains User Registration form, submission of the form will call auth.service.
– login.component contains User Login form, submission of the form will call auth.service and token-storage.service.

– user.service gets access to authority data from Server using Angular HttpClient ($http service).
– auth.service handles authentication and signup actions with Server using Angular HttpClient ($http service).
– every HTTP request by $http service will be inspected and transformed before being sent to the Server by auth-interceptor (implements HttpInterceptor).
– auth-interceptor check and get Token from token-storage.service to add the Token to Authorization Header of the HTTP Requests.

– token-storage.service manages Token inside Browser’s sessionStorage.
