NodeJS part - JWT Angular authentication & authorization part 2

This is the 2nd part of the complete/practical process/example of JWT login/logout process implementation. Here I am explaining NodeJS part. There will be 1 more part (Auth guard).

In this video I will show you how I used JSONWebToken(JWT) for user authentication & Authorization using local-storage.
Here I used JWT, Angular 8, NodeJS & Mysql.
Where in Angular I used: Component-service-interceptor-authguard

Comments are most welcome.
