Installation

There are several ways to use @babel/preset-env-standalone. Pick whichever one you like:

- Use it via UNPKG: https://unpkg.com/@babel/preset-env-standalone@7/babel-preset-env.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/preset-env-standalone`
- Manually grab `babel-preset-env.js` and/or `babel-preset-env.min.js`:
  * Download archived source code from the [GitHub releases page](https://github.com/babel/babel/releases).
  * Unpack it.
  * Grab `babel-preset-env.js` and/or `babel-preset-env.min.js` from `packages/babel-preset-env-standalone`.

Usage
=====

Load `babel-preset-env.js` or `babel-preset-env.min.js` in your environment, **along with babel-standalone**. This is important: You need to load Babel too! It will be registered as an available preset of the @babel/standalone.

Then, just use it like any other preset:

```js
Babel.transform(code, {
  presets: [
    ["@babel/preset-env", {
      "targets": {
        "browsers": "last 1 safari version"
      },
      useBuiltIns: "usage"
    }]
  ]
});
```
