babel-standalone
================

babel-standalone is a standalone build of Babel for use in non-Node.js environments, including browsers.
It's bundled with all the standard Babel plugins and presets.



This fork
=========
The current version of babel-standalone used in this specific fork is `jsgtk` oriented.
I have manually removed from the original uncompressed source all warnings generated and shown via [GJS](https://wiki.gnome.org/action/show/Projects/Gjs?action=show&redirect=Gjs) env.

The minified version drops mostly only spaces and put back double (pointless) pharentesuis with assignments.
The result is visible in [jsgtk](https://github.com/WebReflection/jsgtk#jsgtk) where user modules can use ES6 syntax witohut warnings and within `gjs` executable.



But why?!
=========

It's true that using Babel through Webpack, Browserify or Gulp should be sufficient for most use cases. However, there are some valid use cases for babel-standalone:

 - Sites like [JSFiddle](https://jsfiddle.net/), [JS Bin](https://jsbin.com/), the [REPL on the Babel site](http://babeljs.io/repl/), etc. These sites compile user-provided JavaScript in real-time.
 - Apps that embed a JavaScript engine such as V8 directly, and want to use Babel for compilation
  - Apps that want to use JavaScript as a scripting language for extending the app itself, including all the goodies that ES2015 provides.
  - Integration of Babel into a non-Node.js environment ([ReactJS.NET](http://reactjs.net/), [ruby-babel-transpiler](https://github.com/babel/ruby-babel-transpiler), [php-babel-transpiler](https://github.com/talyssonoc/php-babel-transpiler), etc).

Installation
============

There are several ways to get a copy of babel-standalone. Pick whichever one you like:

- Use it via CDNJS: https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.4.4/babel.min.js. This is a simple way to embed it on a webpage without having to do any other setup.
- Install via NPM: `npm install --save babel-standalone`
- Manually grab `babel.js` and/or `babel.min.js` from the [GitHub releases page](https://github.com/Daniel15/babel-standalone/releases). Every release includes these files.

Usage
=====

Load `babel.js` or `babel.min.js` in your environment. This will expose [Babel's API](http://babeljs.io/docs/usage/api/) in a `Babel` object:

```js
var input = 'const getMessage = () => "Hello World";';
var output = Babel.transform(input, { presets: ['es2015'] }).code;
```

Note that `.babelrc` doesn't work in babel-standalone, as no file system access is available. The presets and/or plugins to use **must** be specified in the options passed to `Babel.transform`.
