[![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-dev-server` can be installed via the Yarn or npm clients. #### Yarn ```bash ❯ yarn add neutrino-middleware-dev-server ``` #### npm ```bash ❯ npm install --save neutrino-middleware-dev-server ``` ## Usage `neutrino-middleware-dev-server` can be consumed from the Neutrino API, middleware, or presets. Require this package and plug it into Neutrino: ```js // Using function middleware format const devServer = require('neutrino-middleware-dev-server'); // Usage with default options neutrino.use(devServer); // Usage with custom options (default options are shown) neutrino.use(devServer, { https: false, port: 5000, host: 'localhost', public: 'localhost', open: false, contentBase: neutrino.options.source, hot: true, historyApiFallback: true, publicPath: '/', headers: { host: 'localhost' }, stats: { assets: false, children: false, chunks: false, colors: true, errors: true, errorDetails: true, hash: false, modules: false, publicPath: false, timings: false, version: false, warnings: true } }); ``` ```js // Using object or array middleware format // Usage with default options module.exports = { use: ['neutrino-middleware-dev-server'] }; // Usage with custom options (default options are shown) module.exports = { use: [ ['neutrino-middleware-dev-server', { https: false, port: 5000, host: 'localhost', public: 'localhost', open: false, contentBase: neutrino.options.source, hot: true, historyApiFallback: true, publicPath: '/', headers: { host: 'localhost' }, stats: { assets: false, children: false, chunks: false, colors: true, errors: true, errorDetails: true, hash: false, modules: false, publicPath: false, timings: false, version: false, warnings: true } }] ] }; ``` By default this middleware will start a development server with Hot Module Replacement support on `http://localhost:5000`. To enable HMR with your application, read the documentation of corresponding Neutrino preset or middleware. It is recommended to call this middleware only in development mode when `process.env.NODE_ENV === 'development'`. More information about usage of Neutrino middleware can be found in the [documentation](https://neutrino.js.org/middleware). ## Middleware options `neutrino-middleware-dev-server` optionally accepts an object with several options to override the default behavior. This object, as seen used above, can accept any [property that is accepted by Webpack Dev Server](https://webpack.js.org/configuration/dev-server/). In addition, you may also specify the following options: - `open`: Optional Boolean value to open the project in the a tab of the default browser. Default is `false`. ## 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. Follow the [contributing guide](https://neutrino.js.org/contributing) for details.
