参考: https://webpack.js.org/api/node/

更多的时间，我们将webpack做为一个nodejs模块来使用

一：新建自己的打包文件build.js

我们在./build/新建一个文件 build.js，内容如下

const webpack = require('webpack')
const webpackConfig = require('./webpackfile.js');
webpack(webpackConfig,(err,stats) => {
  if (err) throw err
  console.log('已打包好了，我们做点别的事')
})

打包

D:\03www2018\study\webpack2017>node ./build/build.js

效果与执行webpack命令一样
写成npm srcipt

"scripts": {
    "abc": "webpack --config ./build/webpackfile.js","def": "webpack-dev-server","tttt": "node build/build.js","test": "echo \"Error: no test specified\" && exit 1"
  },

执行
D:03www2018studywebpack2017>npm run tttt

二：使用webpack编译器

/*const webpack = require('webpack')
const webpackConfig = require('./webpackfile.js');
webpack(webpackConfig,stats) => {
  if (err) throw err
  console.log('已打包好了，我们做点别的事')
})*/

const webpack = require('webpack')
const webpackConfig = require('./webpackfile.js');
const compiler = webpack(webpackConfig)
compiler.run( (err,stats) => {
  if (err) throw err
  console.log('已打包好了，我们做点别的事...')
})
// 编译器运行比上面要快些，但它没有包括watch部分，没有监视，只是编译

既监视又编译

/*const webpack = require('webpack')
const webpackConfig = require('./webpackfile.js');
webpack(webpackConfig,stats) => {
  if (err) throw err
  console.log('已打包好了，我们做点别的事')
})*/

/*const webpack = require('webpack')
const webpackConfig = require('./webpackfile.js');
const compiler = webpack(webpackConfig)
compiler.run( (err,stats) => {
  if (err) throw err
  console.log('已打包好了，我们做点别的事...')
})*/
// 编译器运行比上面要快些，但它没有包括watch部分，没有监视，只是编译，如果要编译，还要加上


const webpack = require('webpack')
const webpackConfig = require('./webpackfile.js');
const compiler = webpack(webpackConfig)
const watching = compiler.watch({
  /* watchOptions */
},stats) => {
  // Print watch/build result here...
  console.log('我一直在监视着呢');
});

三：配合其它node模块上面的打包不够丰富，如果和其它node模块配置可以实现更多的功能如，使用chalk模块来更好的显示提示信息
