U8 - importing and exporting symbols from JavaScript files
CommonJS support
Implements almost full CommonJS support; e.g. to use it, include the following in your module (which is to be imported):
// file: some_module.js
function toExport() { //... }
exports.someFunction = toExport;
// or using module.exports:
module.exports = { someFunction: toExport };
and any combinations of above mentioned.
In the source where you want to import it use:
let imported = require('some_module');
import.someFunction();
// or, using destructuring assignment:
{ someFunction } = { ...require('some_module');
When require
'ing file, the .js extension could be omitted. Expected extension
is .js
.
Import keyword
As for now, the limited support for import
keyword is supported:
import { someFunction, SomeClass } from 'some_module'
Expected file name extension is .js
. All three of .js .mjs .cjs
are allowed
but latter two needs to be explicitly specified.
