Handling observables in interceptors

[mrichar1]

I'm currently looking to use some methods in addResponseInterceptor function which return observables.

With the current code for getList explicitly raises an error if the resulting data is not an array:

ngx-restangular/src/ngx-restangular.ts

Lines 423 to 425 in 7ffda9b

	if (!_.isArray(data)) {
	throw new Error('Response for getList SHOULD be an array and not an object or something else');
	}

This means that you can't use observables or promises in interceptors.

Additionally, I can't find a way to resolve the observable 'inside' the interceptor and have the actual data returned from the interceptor (though I am relatively new to observables/promises so might be missing something here).

Hello @mrichar1. Unfortunately you can't use observables or promises in response interceptors. It might be implemented in next major version of restangular.
