javascript - [webpack] How to reference local plug-ins?

Question

I have a js plug-in that is not available on npm. How can I package it globally?

var webpack = require('webpack');
var path = require('path');
module.exports = {
  entry: {
      main:'./app/index.js'
  },
  output: {
    filename: '[name].js',,
    path:path.resolve(__dirname, 'dist')
  },
  resolve:{
      modules:[
          path.resolve(__dirname, "app"),
          "node_modules"
      ]
  }
}

Use require directly in index.js to introduce an error and report that it cannot be found;

Later I used CommonsChunkPlugin to package it into a vendor but it still didn’t work;

var webpack = require('webpack');
var path = require('path');
var HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
  entry: {
      main:'./app/index.js',
      vendor: ['lib/easeljs/easeljs-0.8.2.min.js','lib/preloadjs/preloadjs-0.6.2.min.js','lib/tweenjs/tweenjs-0.6.2.min.js']
  },
  output: {
    filename: '[name].js',
    path:path.resolve(__dirname, 'dist')
  },
  resolve:{
      modules:[
          path.resolve(__dirname, "app"),
          "node_modules"
      ]
  },
  plugins: [
      new webpack.optimize.CommonsChunkPlugin({
          name: 'vendor'
      }),
      new HtmlWebpackPlugin({
        filename: 'index.html',
        template: './app/index.html'
    })
  ]
}

I searched online for the library you mentioned https://github.com/CreateJS/E...
The first sentence is this.createjs = this.createjs||{}; Obviously the module This in is not window, so an error will occurthis.createjs = this.createjs||{};显然模块中的this不是window，所以会出错
所以要使用imports-loader来打包，在index中import createjs from 'imports-loader?this=>window!createjs';So use imports-loader to package, in the index import createjs from 'imports-loader?this=>window!createjs';, this way createjs The instance can be obtained, but there is still a problem at this time, because webpack cannot find easeljs in the set path, so alias is needed:

resolve: {
    alias: {
         easeljs: path.join(__dirname,'这里确保路径能对应') + '/app/lib/easeljs-0.8.2.combined.js'
    }
}

Update: There is also a related solution in the issue, which also uses imports-loader. The author can refer to https://github.com/CreateJS/E...

index.js

import createjs from 'imports-loader?this=>window!easeljs';

webpack.config.js

  resolve:{
      alias: {
         easeljs: path.join(__dirname,'./app/lib/easeljs/easeljs-0.8.2.min.js')
    }
  },

There is a problem with the picture abovecreatejs 变成了 __WEBPACK_IMPORTED_MODULE_0_imports_loader_this_window_easeljs___default.a
