Modern browsers have very recently started to implement module loaders natively. To natively use a script that imports modules, you'll have to make its type="module".
Here's a very basic working example in Chrome 63:
// index.html<!doctype HTML><html> <head> <script src="index.js" type="module"></script> </head> <body> <div id="text"></div> </body></html>
This is how index.js (the main script file) will look:
// index.jsimport { writeText2Div as write2Div } from './module.js';write2Div('Hello world!')
This is the module that index.js imports (in the same directory):
// module.jsconst writeText2Div = text => document.getElementByID('text').innerText = text;export { writeText2Div };
This, when tested, should show
