An example of Backendless development with Angular 5 using Http Interceptors from the new HttpClientModule, including

This posts shows an example of how to implement a fake or mock backend in Angular and TypeScript.

The below mock backend is built with a custom http interceptor, http interceptors were introduced in Angular 4.3.0 as part of the new improved HttpClientModule (@angular/common/http). For an older version that works with the HttpModule (@angular/http) from previous versions of Angular see this post.

A mock backend is used for doing backendless development in Angular which allows you to demo your code without the need to create a backend server api, it’s perfect for code hosted in Plunker which doesn’t have a backend, or when you’re developing a front end before the backend is available.

I created the below fake backend as part of an Angular User Registration and Login Example & Tutorial that I wrote a while ago and includes mock endpoints for authentication and user management, it uses browser local storage to store data so it can behave just like a real api including data persistance.

Sometimes there’s a need to pass through specific requests to the server instead of being caught by the fake backend, for example when the real backend is partially completed and has some endpoints available.

With Angular http interceptors this is done by calling , you can see the code for passing through requests at the bottom of the code sample below.
