Implementing Token Interceptor and Retry in Angular 4

If you are building a web application using Angular 4 or Angular 5 there’s a good chance that you might be working with JWT tokens. Luckily, implementing token interceptor and retry in Angular 4 and beyond is very easy thanks to the new HTTP Interceptors. Using this, we can add an authorization header to every outbound request while also implementing a retry mechanism for requests that fail due to an expired token.
