[![NPM version][npm-image]][npm-url] [![NPM downloads][npm-downloads]][npm-url] [![Join the Neutrino community on Spectrum][spectrum-image]][spectrum-url] ## Requirements - Node.js v6.10+ - Yarn or npm client - Neutrino v7 ## 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 // Using function middleware format const compile = require('neutrino-middleware-compile-loader'); neutrino.use(compile, { include: [], exclude: [], babel: {} }); ``` ```js // Using object or array middleware format module.exports = { use: [ ['neutrino-middleware-compile-loader', { 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) - `exclude` should be an array of paths to exclude from the compilation. Maps to Webpack's [`Rule.exclude`](https://webpack.js.org/configuration/module/#rule-exclude) - `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`. ## Merging Babel Configuration This package also exposes a function for merging Babel configurations. This comes from the [babel-merge](https://www.npmjs.com/package/babel-merge) package. ```js const { merge } = require('neutrino-middleware-compile-loader'); const together = merge( { presets: [ ['babel-preset-env', { targets: { browsers: ['latest 1 Chrome'] } }] ] }, { presets: [ ['babel-preset-env', { targets: { browsers: ['latest 1 Firefox'] } }] ] } ); console.log(together); // Logs: { presets: [ ['babel-preset-env', { targets: { browsers: [ 'latest 1 Chrome', 'latest 1 Firefox' ] } }] ] } ``` ## 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: | Name | Description | Environments and Commands | | --- | --- | --- | | `compile` | Compiles JS and JSX files from the `src` directory using Babel. Contains a single loader named `babel`. | all | ## Contributing This middleware is part of the [neutrino-dev](https://github.com/mozilla-neutrino/neutrino-dev) repository, a monorepo containing all resources for developing Neutrino and its core presets and middleware.
