NpmInstallWebpackPlugin

Install

$ npm install --save-dev npm-install-webpack-plugin

用法

在 webpack.config.js 中：

plugins: [
  new NpmInstallPlugin();
],

相当于：

plugins: [
  new NpmInstallPlugin({
    // 使用 --save 或者 --save-dev
    dev: false,
    // 安装缺少的 peerDependencies
    peerDependencies: true,
    // 减少控制台日志记录的数量
    quiet: false,
  });
],

可以提供一个 Function 来动态设置 dev：

plugins: [
  new NpmInstallPlugin({
    dev: function(module, path) {
      return [
        "babel-preset-react-hmre",
        "webpack-dev-middleware",
        "webpack-hot-middleware",
      ].indexOf(module) !== -1;
    },
  }),
],
