hapi-webpack-connection

Bridge between Hapi and Webpack

Installation

npm install hapi-webpack-connection

API

WebpackConnection([options])

The WebpackConnection() function is a top-level function exported by the hapi-webpack-connection module.

var WebpackConnection = require('hapi-webpack-connection');
var Webpack = WebpackConnection();

Creates a Webpack object where:

• options - optional webpack configuration object. See the webpack documentation for all available options.

  This object includes also the webpack-dev-server configuration via the devServer property. See the webpack-dev-server documentation for all available options.

  If omitted, the module will try to read the webpack.config.js file in the current working directory. This file should export the configuration object:

    module.exports = {
      // configuration
    };

  This is the defaults merged with the options by the module:

  // Defaut configuration
  {
    devServer: {
      contentBase: process.cwd(),
      filename: null, // Get from output.filename
      historyApiFallback: false,
      host: 'localhost',
      port: 0, // 0 = Randomly selected
      hot: false,
      https: false,
      inline: false,
      lazy: false,
      noInfo: false,
      outputPath: '/',
      publicPath: null, // Get from output.publicPath
      proxy: {},
      quiet: false,
      stats: {
        cached: false,
        cachedAssets: false,
        // colors: true or false, turned on if the terminal supports it
        context: process.cwd()
      }
    },
    output: {
      filename: 'bundle.js',
      path: process.cwd(),
      publicPath: '/'
    }

Webpack properties

webpack.compiler

The webpack compiler instance.

var WebpackConnection = require('hapi-webpack-connection');
var Webpack = WebpackConnection();
 
Webpack.compiler.plugin('done', function(stats) {
  console.log(stats.toString());
});

webpack.connection

The hapi connection configuration object. See the hapi documentaion for all available options.

The connection has a webpack label and exposes the webpack configuration via app.webpack which can later be accessed via connection.settings.app.webpack.

var WebpackConnection = require('hapi-webpack-connection');
var Webpack = WebpackConnection();
 
var Hapi = require('hapi');
var server = new Hapi.Server();
 
server.connection(Webpack.connection);
 
server.start(function () {
  console.log('Server running at:', server.info.uri);
});

webpack.getAssets()

Returns an object where each key is the name of the chunk and the value is the full url of the chunk.

This object will not have any properties until the compilation is done.

var webpackConfig = {
  entry: {
    main: './entry.js'
  }
  output: {
    publicPath: '/assets',
    filename: '[name]-compiled.js'
  }
  devServer: {
    port: 3001
  }
};
 
var WebpackConnection = require('hapi-webpack-connection');
var Webpack = WebpackConnection(webpackConfig);
 
console.log(Webpack.getAssets());
// Compiling...
// Print:
// {}
 
console.log(Webpack.getAssets());
// Compiled...
// Print:
// {
//   main: 'http://localhost:3001/assets/main-compiled.js'
// }

Examples

Using hot-reloading

var webpackConfig = {
  entry: './entry.js',
  output: {
    path: __dirname + '/dist'
  },
  devServer: {
    port: 3000,
    inline: true,
    hot: true
  }
}
 
// The entry will become
// [
//   'webpack-dev-server/client?http://localhost:3000', // from inline
//   'webpack/hot/dev-server', // from inline and hot
//   './entry.js'
// ]
 
var Hapi = require('hapi');
var Webpack = require('hapi-webpack-connection')(webpackConfig);
 
var server = new Hapi.Server();
server.connection(Webpack.connection);
 
server.start(function () {
  console.log('Server running at:', server.info.uri);
});

Using getAssets()

var Hapi = require('hapi');
var Webpack = require('hapi-webpack-connection')();
 
var server = new Hapi.Server();
server.connection(Webpack.connection);
 
server.ext('onPreHandler', (request, reply) => {
  request.pre.assets = Webpack.getAssets();
  return reply.continue();
});
 
server.route({
  path: '/',
  method: 'GET',
  handler: function(request, reply) {
    return reply(request.pre.assets);
  }
});
 
server.start(function () {
  console.log('Server running at:', server.info.uri);
});

Using glue

var Glue = require('glue');
var Webpack = require('hapi-webpack-connection')();
 
var manifest = {
  connections: [
    Webpack.connection,
    {
      port: 3001,
      labels: [
        'myApp'
      ]
    }
  ],
  server: {
    // ... some server options
  },
  plugins: {
    // ... some plugins to register
  }
}
 
Glue.compose(manifest, function (error, server) {
  if (error) {
    return console.error(error);
  }
 
  server.start(function () {
    console.log('Server running at:', server.info.uri);
  });
});
