Angular 8 Angular2-JWT Tutorial

JSON Web Tokens(JWT) are used to secure communication between client and servers. JWT is an encrypted string which is generated by the server after verification of user credentials when they log in. After that this JWT is used to verify the authenticity of the user asking for server responses.

So at the server end the user always need to pass JWT in HTTP call’s header, which is verified/ matched to generated one on the login process.

In our previous tutorial, we implemented JWT and in our Angular application using angular2-jwt package, which makes it easy to add JWT in every HTTP call and also provide other options to manage JWT at the client end.

In this article, we will discuss the implementation of JSON Web Token Authentication in Angular 8 application by using angular2-jwt package.

This post is compatible with Angular v6+ and RxJS v6+

What is JWT?

JWT or JSON Web Token is an encrypted string which contains information related to the logged in user and secret key, this token is generated at server end after a user is authentication. This JWT is used for further communication between clients and servers.

After getting JWT from the server, every HTTP call to RESTful APIs must have an Authorization header set with JWT, which is encoded at the server end for authenticating the source. After successful validation data is transferred. Continue reading Angular 8 | JSON Web Token Authentication Tutorial with Login/ Dashboard and Guards using angular2-jwt
