折腾:

【已解决】如何把react-hot-boilerplate的项目打包为生产环境

后,对于之前常见的,npm run build之前和之后要做的一些事情,

一直希望写个脚本自动运行,以减少手动的操作的浪费时间

现在终于经过一番折腾,基本上实现了,部分的工作的自动化。

参考别人的:

preact的boilerplate的写法:

  “scripts”: {
    “dev”: “cross-env NODE_ENV=development webpack-dev-server –inline –hot –progress”,
    “start”: “serve build -s -c 1”,
    “prestart”: “npm run build”,
    “build”: “cross-env NODE_ENV=production webpack -p –progress”,
    “prebuild”: “mkdirp build && ncp src/assets build/assets”,
    “lint”: “eslint src”
  },

自己去加上自己的逻辑,最后为:

     “prebuild”: “rm -rf build build.zip && mkdir -p build/dist && ncp src/assets build/dist && cp index.html build”,
    “build”: “npm run prebuild && cross-env NODE_ENV=production webpack -p –progress –colors && npm run postbuild”,
    “postbuild”: “zip -r build.zip build”

此处的prebuild和build,postbuild是自己写的。

注:

此处需要先去安装ncp工具:

npm install ncp

对于上述写法,直接运行npm run build,即可起到所需要的效果:

➜  react-hot-boilerplate git:(master) ✗ npm run build

【总结】

对应的文件夹结构和文件是:

此处的逻辑是:

npm run build

会先去运行:

npm run prebuild

在运行npm build部分的内容

最后再去执行:

npm run postbuild

分别的含义是:

1.npm run prebuild

(1)rm -rf build build.zip

删除(之前)创建的build文件夹和(之前)压缩出来的文件build.zip

(2)mkdir -p build/dist

创建build和build/dist文件夹

(3)ncp src/assets build/dist

把src下面的assets(其中包括img等文件)整个文件夹的都复制到build/dist

(4)cp index.html build

把html的index.html文件拷贝到build文件夹中

2.npm run build

(1)npm run prebuild

在运行build之前,先去执行创建文件夹等工作

(2)cross-env NODE_ENV=production webpack -p –progress —colors

执行webpack -p的给production打包

(3)npm run postbuild

在build之后执行一些动作,包括压缩打包

3.npm run postbuild

(1)zip -r build.zip build

把build文件夹及其下的文件都压缩打包为build.zip

【后记1】

后来看到别处的:

    new CopyWebpackPlugin([
      { from: ‘./manifest.json’, to: ‘./’ },
      { from: ‘./favicon.ico’, to: ‘./’ }
    ])

所以去搜索:

CopyWebpackPlugin

GitHub – kevlened/copy-webpack-plugin: Copy files and directories in webpack

webpack进阶之插件篇 | 好JSER好JSER

webpack插件& loader篇 – 简书

是去把文件(夹)拷贝到build的文件夹

所以去试试:

➜  react-hot-boilerplate git:(master) ✗ npm install –save-dev copy-webpack-plugin
npm WARN babel-loader@6.2.10 requires a peer of webpack@1 || 2 || ^2.1.0-beta || ^2.2.0-rc but none was installed.
npm WARN react-dom@15.6.1 requires a peer of react@^15.6.1 but none was installed.
added 8 packages in 10.011s

经过尝试,结果是:

用:

// import CopyWebpackPlugin from ‘copy-webpack-plugin’;
var CopyWebpackPlugin = require(‘copy-webpack-plugin’);
var isProd = (process.env.NODE_ENV === ‘production’);
let commonPlugins = [
  new webpack.optimize.CommonsChunkPlugin({
    name: ‘vendor’,
    filename: ‘vendor.bundle.js’
  }),
];
if (isProd) {
  commonPlugins.push(
    new CopyWebpackPlugin([
      //{ from: ‘./index.html’, to: ‘build’ },
      // { from: ‘src/assets’, to: ‘build/dist’ },
      { from: ‘./index.html’ },
      { from: ‘src/assets’, to: ‘dist’ },
    ])
  );
}
module.exports = {
  plugins: commonPlugins,
}

不需要之前的:

mkdir -p build/dist

去创建对应的build以及build/dist文件夹了。

就可以取代之前的:

ncp src/assets build/dist && cp index.html build

去拷贝对应的文件和图片,并且自动创建对应的目标文件夹了。

优化后的代码为:

package.json

  “scripts”: {
。。。
    “prebuild”: “rm -rf build build.zip”,
    “build”: “npm run prebuild && cross-env NODE_ENV=production webpack -p –progress –colors && npm run postbuild”,
    “postbuild”: “zip -r build.zip build”
  },

webpack.config.js

// import CopyWebpackPlugin from ‘copy-webpack-plugin’;
var CopyWebpackPlugin = require(‘copy-webpack-plugin’);
var path = require(‘path’);
var webpack = require(‘webpack’);
// const ENV = process.env.NODE_ENV || ‘development’;
var isProd = (process.env.NODE_ENV === ‘production’);
console.log(`process.env.NODE_ENV=${process.env.NODE_ENV}, isProd=${isProd}`);
//process.env.NODE_ENV=development, isProd=false
let commonPlugins = [
  // new webpack.ProvidePlugin({
  //   $: ‘jquery’,
  //   ‘window.jQuery’: ‘jquery’,
  //   jQuery: ‘jquery’,
  //   ‘window.$’: ‘jquery’,
  // }),
  new webpack.optimize.CommonsChunkPlugin({
    name: ‘vendor’,
    filename: ‘vendor.bundle.js’
  }),
  // new webpack.HotModuleReplacementPlugin()
];
if (isProd) {
  // Note: current not add UglifyJsPlugin for production for:
  // when webpack -p, it will auto added UglifyJsPlugin, then omit here UglifyJsPlugin settings
  // commonPlugins.push(
  //   new webpack.optimize.UglifyJsPlugin({
  //     minimize: true
  //   })
  // );
  commonPlugins.push(
    new CopyWebpackPlugin([
      //{ from: ‘./index.html’, to: ‘build’ },
      // { from: ‘src/assets’, to: ‘build/dist’ },
      { from: ‘./index.html’ },
      { from: ‘src/assets’, to: ‘dist’ },
    ])
  );
}
module.exports = {
  entry: {
    index: ‘./src/index.js’,
    vendor : [
      // ‘webpack-hot-middleware/client’,
      ‘react-hot-loader/patch’,
      ‘./src/adminlte_app.js’
    ],
  },
  output: {
    // path: path.join(__dirname, ‘public’),
    // path: path.join(__dirname, ‘build’),
    path: path.resolve(__dirname, ‘build’),
    // filename: ‘bundle.js’,
    filename: ‘[name].js’,
    // filename: ‘./build/[name].js’,
    // publicPath: ‘/public/’
    // publicPath: ‘/public’
    // publicPath: ‘/assets/’
    // publicPath: ‘http://localhost:3000/public/’
  },
  // devtool: isProd ? ‘cheap-module-source-map’ : ‘eval’,
  devtool: isProd ? ‘false’ : ‘eval’,
  devServer:{
    // hot: true,
    // contentBase: path.join(__dirname, ‘dist’),
    contentBase: path.resolve(__dirname, ‘build’),
    // publicPath: path.resolve(__dirname, ‘build’),
    compress: true,
    port: 3000,
    historyApiFallback: true
  },
  plugins: commonPlugins,
  module: {
    // loaders: [
    rules: [
      {
        test: /\.js$/,
        //loaders: [‘react-hot-loader’, ‘babel-loader’],
        // use: [‘react-hot-loader’, ‘babel-loader’],
        use: [‘babel-loader’],
        // include: path.join(__dirname, ‘src’)
      },
      {
        test: /\.css$/,
        // loaders: [‘style-loader’, ‘css-loader’],
        use: [‘style-loader’, ‘css-loader’],
        // include: path.join(__dirname, ‘src’)
      }
    ]
  }
};

即可。

【后记2】

后来参考别的项目时注意到:

build中,并没有显式地调用prebuild,但是npm run build会自动先去执行prebuild

所以搜:

prebuild build npm run

参考:

npm scripts 使用指南 – 阮一峰的网络日志

得知:

七、钩子
npm 脚本有pre和post两个钩子。举例来说,build脚本命令的钩子就是prebuild和postbuild。
“prebuild”: “echo I run before the build script”,
“build”: “cross-env NODE_ENV=production webpack”,
“postbuild”: “echo I run after the build script”
用户执行npm run build的时候,会自动按照下面的顺序执行。
npm run prebuild && npm run build && npm run postbuild
因此,可以在这两个钩子里面,完成一些准备工作和清理工作。下面是一个例子。
“clean”: “rimraf ./dist && mkdir dist”,
“prebuild”: “npm run clean”,
“build”: “cross-env NODE_ENV=production webpack”
npm 默认提供下面这些钩子。
prepublish,postpublish
preinstall,postinstall
preuninstall,postuninstall
preversion,postversion
pretest,posttest
prestop,poststop
prestart,poststart
prerestart,postrestart
自定义的脚本命令也可以加上pre和post钩子。比如,myscript这个脚本命令,也有premyscript和postmyscript钩子。不过,双重的pre和post无效,比如prepretest和postposttest是无效的。
npm 提供一个npm_lifecycle_event变量,返回当前正在运行的脚本名称,比如pretest、test、posttest等等。所以,可以利用这个变量,在同一个脚本文件里面,为不同的npm scripts命令编写代码。请看下面的例子。
const TARGET = process.env.npm_lifecycle_event;
if (TARGET === ‘test’) {
  console.log(`Running the test task!`);
}
if (TARGET === ‘pretest’) {
  console.log(`Running the pretest task!`);
}
if (TARGET === ‘posttest’) {
  console.log(`Running the posttest task!`);
}
注意,prepublish这个钩子不仅会在npm publish命令之前运行,还会在npm install(不带任何参数)命令之前运行。这种行为很容易让用户感到困惑,所以 npm 4 引入了一个新的钩子prepare,行为等同于prepublish,而从 npm 5 开始,prepublish将只在npm publish命令之前运行。

所以,之前脚本可以去掉调用npm run prebuild和npm run postbuild,且还可以再加上clean,变为:

  “scripts”: {
    “dev”: “cross-env NODE_ENV=development webpack-dev-server –progress –colors –hot –inline –open”,
    “lint”: “eslint src”,
    “clean” : “rm -rf build/ build.zip”,
    “package” : “zip -r build.zip build/”,
    “prebuild”: “npm run clean”,
    “build”: “cross-env NODE_ENV=production webpack -p –progress –colors”,
    “postbuild”: “npm run package”
  },

然后运行

npm run build

会自动先后执行prebuild和postbuild:
