load-script2 
Dynamic script loading for modern browsers
Works in the browser with browserify!
install
npm install load-script2
This package works in the browser with browserify. If you do not use a bundler, you can use the standalone script directly in a <script> tag.
usage
const loadScript = require('load-script2')
const script = await loadScript('foo.js')
console.log(script.src);// Prints 'foo'.js'differences to load-script
load-script2 does not support legacy browsers like IE8 because these browsers
do not have standards-based DOM APIs. load-script2 also removes many esoteric
options, which aren't needed most of the time and adds promises support.
The size of load-script2 is 509 bytes, compared to 655 bytes for load-script (minified
and gzipped).
API
promise = loadScript(src, [attrs], [parentNode])
Append a <script> node with the given src URL to the <head> element in the DOM.
src
Any url that you would like to load. May be absolute or relative.
attrs (optional)
An object that contains HTML attributes to set on the <script> tag. For
example, the value { id: 'hi' } would set the attribute id="hi" on the
<script> tag before it is injected.
parentNode (optional)
The HTML node to which the <script> tag will be appended. If not specified,
defaults to the <head> tag.
promise
Returns a promise which resolves to the script node that was appended to the
DOM, or rejects with err if any occurred.
