Below I will share with you a method of webpack packaging and loading files to a specified location. It has a good reference value and I hope it will be helpful to everyone.

The best thing about using webpack for packaging is that you can directly require files, but this

also brings a problem, that is, all the files are integrated together, then this package too big.

Based on this: Let’s learn about the packaging of webpack (mainly how to package the content modules we need separately,

And store it according to the storage path we set)

First, in the webpack.config.js file

entry entry function output indicates which ones need to be packaged separately Into a js package:

entry: {
  main: path.resolve(__dirname,&#39;src/index.js&#39;),
  jq: [&#39;jquery&#39;],
  react: [&#39;react&#39;],
  redom: [&#39;react-dom&#39;]
},
output: {
  path: path.resolve(__dirname,&#39;dist&#39;),
  publishPath: &#39;dist/&#39;,
  filename: &#39;[name].js&#39;
 },
plugin: [
  new webpack.optimize.CommonsChunkPlugin(&#39;jq&#39;,&#39;jq.js&#39;),
  new webpack.optimize.CommonsChunkPlugin(&#39;vendors&#39;,&#39;vendors.js&#39;),
  new webpack.optimize.CommonsChunkPlugin(&#39;redom&#39;,&#39;redom.js&#39;)
]

Configure as above, so that when the file is generated, the three js js jq.js, vendors.js, and redom.js will be added to the dist directory.

The above solves the problem of us packaging multiple packages;

So if we want to store the packaged js in a specified location, how do we do it? Don’t worry, let’s follow The specific implementation of

is as follows (in fact, the difference is mainly in the entry function):

entry: {
  &#39;./common/main&#39;: path.resolve(__dirname,&#39;src/index.js&#39;),
  &#39;./jquery/jq&#39;: [&#39;jquery&#39;],
  &#39;./react/react&#39;: [&#39;react&#39;],
  &#39;./reactdom/redom&#39;: [&#39;react-dom&#39;]
 },

Copy after login

As shown above, the four js will be stored in the four files under the dist we formulated. folder. (Note: At this time, you no longer need to use the webpack.optimize.CommonsChunkPlugin plug-in)

Finally, paste the left and right webpack.config.js codes:

var webpack = require('webpack');
var path = require('path');
module.exports = {
 entry: {
  &#39;./common/main&#39;: path.resolve(__dirname,&#39;src/index.js&#39;),
  &#39;./jquery/jq&#39;: [&#39;jquery&#39;],
  &#39;./react/react&#39;: [&#39;react&#39;],
  &#39;./reactdom/redom&#39;: [&#39;react-dom&#39;]
 },
 output: {
  path: path.resolve(__dirname,'dist'),
  publishPath: 'dist/',
  filename: '[name].js'
 },
 module: {
  loaders: [
   {
    test: /\.scss$/,
    loader: 'style!css!sass'
   },
   {
    test: /\.js$/,
    exclude: /node_modules|vue\/dist|vue-router\/|vue-loader\/|vue-hot-reload-api\/|presets\//,
    loader: 'babel'
   },
   {
    test: /\.(png|jpg|gif)$/,
    loader: 'url?limit=40000'
   }
  ]
 },
 babel: {
  presets: ['es2015','stage-0','react'],
  plugins: ['transform-runtime',["antd",{"style": "css"}]]
 },
 resolve: ['js','jsx','css'],
 plugins:[
  new webpack.ProvidePlugin({
   $:"jquery",
   jQuery:"jquery",
   "window.jQuery":"jquery"
  })
 // new webpack.optimize.CommonsChunkPlugin('jq','jq.js'),
 // new webpack.optimize.CommonsChunkPlugin('vendors','vendors.js'),
 // new webpack.optimize.CommonsChunkPlugin('redom','redom.js')
 ]
};
