Angular Security - Authentication With JSON Web Tokens (JWT): The Complete Guide


The goal here is to discuss JWT-based Authentication Design and Implementation in general, by going over the multiple design options and design compromises involved, and then apply those concepts in the specific context of an Angular Application.


Because Authentication also requires some server code, we will show that too so that we have the whole context and can see how all the multiple parts work together

Server code is written in node.js specifically to validate SPA like angular App

JWTs are digitally signed JSON payloads, encoded in a URL-friendly string format.

A JWT can contain any payload in general, but the most common use case is to use the payload to define a user autthentication.

The key thing about JWTs is that in order to confirm if they are valid, we only need to inspect the token itself and validate the signature, without having to contact a separate server for that, or keeping the tokens in memory or in the database between requests.
