Selectively Switch off XHRBackend Provider per call

[momoadeli]

As real endpoints come on line we would like for THAT particular endpoint to be called for real while others continue with their in mem calls.

I'm aware of InMemoryWebApiModule.forRoot(InMemoryMockAPIDataService, {passThruUnknownUrl: true}). However, this universally overrides the XHRBackend and disables all in memory http calls. Is there a way to switch off the in memory mock selectively and make the real http call PER endpoint?

Thanks!

I believe it can be achieved with following workaround

From above plnkr:

Hero Service - requires to be served from Backend Hero Search Service - requires to be served from In Memory Web Api

Note: both services use the same collection: heroes

In app/app.module.ts set config option apiBase to something like api/root/ ( key: apiBase path should contain more than one token, apiBase config must be set and external api must not be identical to apiBase value set):

...
InMemoryWebApiModule.forRoot(InMemoryDataService, {apiBase:"api/root/", passThruUnknownUrl: true }),
...

In hero-search.service, that is to be served from In Memory

private heroSearchUrl = 'api/root/heroes/?name='

In hero.service, that is to be served from real external service

private heroesUrl = 'https://58ac43fef989751200f99333.mockapi.io/v1/heroes/';
