This module aim is to bring both CommonJS like module behavior on Web browsers,
and a promise based module.import(path) to both browsers and NodeJS.
Yes, it resolves paths relatively to the current one!
<!doctype html>
<html>
<script
id="common-js"
data-main="/js-browser/main.js"
src="common.js"
></script>
</html>
Having a single top level script is all it takes to be able to load asynchronously any other file or module.
The main entry point /js-browser/main.js will resolve relative paths from /js-browser/ folder.
Its loaded modules will resolve their own paths from where they've been loaded, and so on. The same goes for NodeJS.
// /js-browser/main.js loading /js-browser/test.js
module.import('./test').then(function (test) {
test('Hello CommonJS!');
// will output:
// Hello CommonJS!
// from /js-browser/test.js
});
// the /js-browser/test.js content
module.exports = function (message) {
alert(message + '\nfrom ' + module.filename);
};
Promise.all([
module.import('./a'),
module.import('//cdn.something.com/cool.js'),
module.import('../sw.js'),
module.import('/root/too.js')
]).then(function (modules) {
const [a, cool, sw, too] = modules;
});
importScripts, a dynamic import proposal, you name it ... this one actually works and it's backward compatible with modules that don't care about this solution existing.Function, which is not the same, and it does exactly what a script loading your code would do. Actually, it does something better. It makes the module run on strict by default and it avoids global scope pollution, like a proper module system.Copyright (C) 2017 by Andrea Giammarchi - @WebReflection
