# Neutrino Compile Loader Middleware
[![NPM version][npm-image]][npm-url] [![NPM downloads][npm-downloads]][npm-url] [![Join Slack][slack-image]][slack-url]
`neutrino-middleware-compile-loader` is Neutrino middleware for compiling source code with Babel.
## Requirements
- Node.js v6.9+
- Yarn or npm client
- Neutrino v5
## Installation
`neutrino-middleware-compile-loader` can be installed via the Yarn or npm clients.
#### Yarn
```bash
❯ yarn add neutrino-middleware-compile-loader
```
#### npm
```bash
❯ npm install --save neutrino-middleware-compile-loader
```
## Usage
`neutrino-middleware-compile-loader` can be consumed from the Neutrino API, middleware, or presets. Require this package
and plug it into Neutrino:
```js
const compile = require('neutrino-middleware-compile-loader');
neutrino.use(compile, {
include: [],
exclude: [],
babel: {}
});
```
- `include` should be an array of paths to include in the compilation. Maps to Webpack's
[`Rule.include`](https://webpack.js.org/configuration/module/#rule-include)
- `babel` is a [Babel configuration object](https://babeljs.io/docs/usage/api/#options), consumed by babel-loader. Use
this to set properties such as `presets`, `plugins`, and `env`.
## Customization
`neutrino-middleware-compile-loader` creates some conventions to make overriding the configuration easier once you are
ready to make changes.
### Rules
The following is a list of rules and their identifiers which can be overridden:
- `compile`: Compiles JS and JSX files from the `src` directory using Babel. Contains a single loader named `babel`.
