getItemResource

Function 
import { getItemResource } from "@esri/arcgis-rest-portal";

// Parses contents as blob by default getItemResource("3ef", { fileName: "resource.jpg", ...}) .then(resourceContents => {});

// Can override parse method getItemResource("3ef", { fileName: "resource.json", readAs: 'json', ...}) .then(resourceContents => {});

// Get the response object instead getItemResource("3ef",{ rawResponse: true, fileName: "resource.json" }) .then(response => {})

Fetches an item resource and optionally parses it to the correct format.

Note: provides JSON parse error protection by sanitizing out any unescaped control
characters before parsing that would otherwise cause an error to be thrown
