Usage

import {Etl} from 'proc-that';
import {RestExtractor} from 'proc-that-rest-extractor';

new Etl().addExtractor(extractor).start().subscribe(/*...*/);

Custom result set

If the called API delivers a masked result (i.e. a JSON object with a data property) you can pass a function into the constructor that is called on the result.

import {Etl} from 'proc-that';
import {RestExtractor, RestExtractorMethod} from 'proc-that-rest-extractor';

let extractor = new RestExtractor('http://my-rest-url.com/posts', RestExtractorMethod.Get, result => result.data);

new Etl().addExtractor(extractor).start().subscribe(/*...*/);
