Installation
npm install rx-script-loaderUsage
ES2015 module import:
import { ScriptLoader } from 'rx-script-loader';
// ...
const scripts =[
{src:'https://cdnjs.cloudflare.com/ajax/libs/ramda/0.26.1/ramda.js', defer: true, async: false},
{src:'https://cdnjs.cloudflare.com/ajax/libs/rxjs/6.4.0/rxjs.umd.min.js'}
];
const libScriptsLoader = new ScriptLoader(scripts);
libScriptsLoader.load();
libScriptsLoader.loadStatus().subscribe(status => console.log('scripts loaded', status));
The consumer also can use the library by loading it via a script tag:
<!doctype html>
<html>
...
<script src="dist/rx-script-loader.js"></script>
<script>
const scripts =[
{src:'https://cdnjs.cloudflare.com/ajax/libs/ramda/0.26.1/ramda.js', defer: true, async: false},
{src:'https://cdnjs.cloudflare.com/ajax/libs/rxjs/6.4.0/rxjs.umd.min.js'}
];
const scriptLoader = new RxScriptLoader.ScriptLoader(scripts);
scriptLoader.load();
scriptLoader.loadStatus().subscribe(status => console.log('scripts loaded', status));
</script>
</html>Script Model
src - string, required
defer - true/false, optional
async - true/false, optional
ASYNC AND DEFER
Both async and defer are script attributes:
if you provide both, async takes precedence on modern browsers. Old browsers that support defer but do not support async will fallback to defer.
