What is the alternative to $templateCache in Angular2 and how can CachedResourceLoader be utilized in its place?

While I have come across 2 similar questions on Stack Overflow and here, none of them seem to provide a solution.

After delving into the Angular repository, I stumbled upon this issue where they inquire about an alternative for templateCache in Angular 2, only to close it suggesting the usage of CachedResourceLoader.

My query is how can we utilize CachedResourceLoader as a replacement for templateCache? Despite scouring through Google search results, I haven't been able to find any relevant information. Perhaps my search approach is misguided or there's something that eludes me.

The response to this question could potentially address those other 2 familiar queries.

Here's an example showcasing the functionality typically provided by templateCache in AngularJS:

Adding:

var myApp = angular.module('myApp', []);
myApp.run(function($templateCache) {
  $templateCache.put('templateId.html', 'This is the content of the template');
});

Retrieval via $templateCache:

$templateCache.get('templateId.html')

Or retrieval:

myApp.component('myComponent', {
   templateUrl: 'templateId.html'
});

CachedResourceLoader is a hidden gem in Angular 2+ that serves as a replacement for AngularJS's $templateCache:

This resource loader utilizes a template cache to eliminate the need for actual loading of resources.

The template cache must be set up and injected into window.$templateCache through a separate process.

To make use of it, simply include the ResourceLoader provider:

{provide: ResourceLoader, useClass: CachedResourceLoader}

You can also access this feature through the existing RESOURCE_CACHE_PROVIDER export.

The contents of window.$templateCache should consist of URL-response pairs.

Remember to specify the ResourceLoader before compilation by providing it in the compiler options rather than the application module.

For reference, here is an example:

import {RESOURCE_CACHE_PROVIDER} from '@angular/platform-browser-dynamic';
import {COMPILER_OPTIONS} from '@angular/core';

window['$templateCache'] = { 'app.html': `...`};

platformBrowserDynamic({
  provide: COMPILER_OPTIONS,
  useValue: { providers: [RESOURCE_CACHE_PROVIDER] },
  multi: true
}).bootstrapModule(AppModule)

Unlike AngularJS's $templateCache, CachedResourceLoader does not support fetching missing templates. In most cases, this behavior is preferred. If customization is needed, consider creating a custom implementation based on the default ResourceLoader implementation.
