To use the ES2015+ syntax in a JavaScript file, add the extension .es
to its
name. For example, you rename file filename.js
to filename.es.js
. The
extension indicates it uses ES2015+ syntax and must therefore be transpiled by
Babel before deployment.
ES2015+ advanced features, such as
generators,
are available to you if you import the polyfillBabel
class from the
polyfill-babel
module:
import polyfillBabel from 'polyfill-babel'
The Babel Polyfill emulates a complete ES6 environment. Use it at your own discretion, as it loads a large amount of code. You can inspect https://github.com/zloirock/core-js#core-js to see what’s polyfilled.
Once you’ve completed writing your module, you can expose it by creating a
package.json
file that specifies your bundle’s name and version. Make sure to
create this in your module’s root folder. Below is an example package.json
file for a js-logger
module:
{
"name": "js-logger",
"version": "1.0.0"
}
The Module Config Generator creates the module based on this information. There you have it! In just a few steps you can prepare your module to leverage the latest JavaScript standard features and publish it.
