带 Webpack 的 Rails

Question

我正在使用 ReactOnRails 应用程序，并且我有node-modules使用npm. 我怎样才能让这些JavaScript libaries可用app/assets/javascript/application.js，所以我不必例如安装jquery在我的模块，并在我的Gemfile？

这是我的 webpack 配置文件：

/* eslint comma-dangle: ["error",
  {"functions": "never", "arrays": "only-multiline", "objects":
"only-multiline"} ] */

const webpack = require('webpack');
const path = require('path');

const devBuild = process.env.NODE_ENV !== 'production';
const nodeEnv = devBuild ? 'development' : 'production';

const config = {
  entry: [
    'es5-shim/es5-shim',
    'es5-shim/es5-sham',
    'babel-polyfill',
    './app/bundles/Home/startup/registration',
  ],

  output: {
    filename: 'webpack-bundle.js',
    path: '../app/assets/webpack',
  },

  resolve: {
    extensions: ['', '.js', '.jsx'],
    alias: {
      react: path.resolve('./node_modules/react'),
      'react-dom': path.resolve('./node_modules/react-dom'),
    },
  },
  plugins: [
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify(nodeEnv),
      },
    }),
  ],
  module: {
    loaders: [
      {
        test: require.resolve('react'),
        loader: 'imports?shim=es5-shim/es5-shim&sham=es5-shim/es5-sham',
      },
      {
        test: /\.jsx?$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
      },
    ],
  },
};

module.exports = config;

if (devBuild) {
  console.log('Webpack dev build for Rails'); // eslint-disable-line no-console
  module.exports.devtool = 'eval-source-map';
} else {
  config.plugins.push(
    new webpack.optimize.DedupePlugin()
  );
  console.log('Webpack production build for Rails'); // eslint-disable-line no-console
}

Rails 5.1 带有webpacker并删除了默认jquery-rails依赖项，但如果您愿意，您仍然可以使用它。在模板中：

<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>

将使用传统资产管道（来自app/assets/javascript/application.js）编译 JS 。

尽管

<%= javascript_pack_tag 'application' %>

将app/javascript/packs/application.js使用 webpacker编译您的 JS 模块。您可以使用以下方法触发手动模块编译：

rails webpacker:compile
