# Note: DEPRECATED. Please use [babel-preset-env](https://github.com/babel/babel-preset-env) instead.
This package is no longer the recommended way to polyfill with Babel. The new best practice is to use [babel-preset-env](https://github.com/babel/babel-preset-env).
----------
## Babel 6.x presets for Node 5.x (updated regularly!)
Node 5.x brings ~59% [native ES6/ES2015 coverage](https://nodejs.org/en/docs/es6/).
This preset for Babel 6 attempts to bridge the gap for the much of the remaining 41% of the evolving ECMAScript spec using [Babel plug-ins](https://github.com/babel/babel/tree/master/packages), from stage 0 and up.
## Motivation
Babel 6.x is awesome, but simply including the [ES2015 preset](https://www.npmjs.com/package/babel-preset-es2015) means you're transpiling features
that your Node 5.x installation can already do faster and natively, replacing them with inferior / old code.
This preset complements existing V8-native functionality - it doesn't work _around_ it.
The end result is nearly always a faster build and script execution time.
## Key features:
* Strict mode, to enable Classes and `let` (via [babel-plugin-transform-strict-mode](https://www.npmjs.com/package/babel-plugin-transform-strict-mode))
* Removes trailing commas from function calls (via [babel-plugin-syntax-trailing-function-commas](https://www.npmjs.com/package/babel-plugin-syntax-trailing-function-commas))
* CommonJS import/export module syntax ([babel-plugin-transform-es2015-modules-commonjs](https://www.npmjs.com/package/babel-plugin-transform-es2015-modules-commonjs))
* [Destructuring](http://www.2ality.com/2015/01/es6-destructuring.html) (via [babel-plugin-transform-es2015-destructuring](https://www.npmjs.com/package/babel-plugin-transform-es2015-destructuring))
* Default and rest parameters (via [babel-plugin-transform-es2015-parameters](https://www.npmjs.com/package/babel-plugin-transform-es2015-parameters))
* Sticky RegEx (via [babel-plugin-transform-es2015-sticky-regex](https://www.npmjs.com/package/babel-plugin-transform-es2015-sticky-regex))
* Unicode RegEx (via [babel-plugin-transform-es2015-unicode-regex](https://www.npmjs.com/package/babel-plugin-transform-es2015-unicode-regex))
* Async/await (via [babel-plugin-transform-async-to-generator](https://www.npmjs.com/package/babel-plugin-transform-async-to-generator) and [babel-plugin-syntax-async-functions](https://www.npmjs.com/package/babel-plugin-syntax-async-functions))
**Note: This package originally shipped with the React preset, but to avoid bloat, doesn't any longer. If you want to add that, please install [babel-preset-react](https://www.npmjs.com/package/babel-preset-react) too**
## Usage instructions
## Installation
Install via NPM the usual way:
`npm i babel-preset-node5`
## Usage
### Via `.babelrc` (recommended)
Create a `.babelrc` file in your project root, and include 'node5' in your preset path:
```js
{
"presets": [
"node5"
]
}
```
Now whenever you run `babel-node`, it will polyfill your app with the ES2015 features that Node 5 is missing.
### Via CLI
`$ babel script.js --presets node5`
### Via Node API
If you don't want to use a project-wide `.babelrc` file (as above):
```js
require("babel-core").transform("code", {
presets: ["node5"]
});
```
And if you _do_, and you want to use vanilla `node` instead of `babel-node` as your CLI, you can create an entry script that references your pre-transpiled code like so:
```js
require('babel-register');
require('path/to/es6/script');
```
... which will then run everywhere Node can.
Of course, make sure to `npm i -S babel-core` or `npm i -S babel-register` respectively, to grab the NPM packages you'll need to transpile on-the-fly.
### Webpack, Gulp, Browserify, etc
Follow vendor instructions and include `node5` in your babel "preset" list.
## How to add React support
Babel has a ready-made preset for React, and you now need to install it separately.
Just grab it via NPM:
`npm i babel-preset-react`
And then add it to your "presets" list in `.babelrc`:
```js
{
"presets": [
"node5",
"react"
]
}
```
## How to use async/await
The async/await proposal allows you to wait on a Promise, and write asynchronous code that looks synchronous.
Here's an example:
```js
async function getUsers(howMany) {
try {
const response = await fetch(`http://jsonplaceholder.typicode.com/users/${howMany}`); // <-- a Promise
return response.json(); // <-- Another promise.
} catch(e) {
console.log('some kind of error occurred: ', e)
}
}
getUsers(10).then(users => {
// "users" contains the result of `response.json()`. Async functions *always*
// return a promise, even if that means wrapping a non-Promise in Promise.resolve
})
```
In the above example, `fetch` returns a promise. By prefixing the function with `async` and prefixing every Promise with `await`, we avoid the typical `.then()` chain inside of the function block and can reason about the flow of the application a little more clearly.
We can also wrap promises in `try/catch` blocks, instead of bolting on `.catch()` chains.
The necessary babel plug-ins to use async/await are included in this package, so you can use this syntax right away.
## Using with Webpack 2 or Rollup?
If you want to enable 'tree shaking' in Webpack 2 or Rollup, you can optionally remove transpiling down to CommonJS by passing `{ "modules": false }` as an option when including this module in your `.babelrc` file, like so:
```js
{
"presets": [
["node5", {
"modules": false
}]
]
}
```
