The basic configuration of the 02-webpack - run webpack

WebPack mounted in 
        the first mounting global npm i webpack - after the first installation g after installation becomes unnecessary to 
        run in the project root npm i webpack catalog --save- dev mounted to project dependencies 
        PS = " dist directory represents the product directly to the user-level directory 
        syntax ul > li {10 * this is the first $ li} this is a fast syntax

 

Make a line of each color features are 4 steps 

         installation package describes the init file npm - the y-new version of the node that will own the 

         npm i jQuery -S installation jq saved to rely on the list went to the E: \ vuekaifa \ lib \ 05day- webpack- interlaced color> this directory to 

         05day -webpack- interlaced color directory == "New New index.html file in the src directory under the src directory create a file in the src directory mian.js 

         src directory created imgs folder and js folder 

         05day -webpack- interlaced color directory ==> Create directory dist 

         introduced jq introduced syntax file is in mian.js import ** ** from it is introduced into the module es6 embodiment 
             1 as import $ from 'jquery'    attention to the case 
             from the incoming file to know first is to look at their brothers and brothers directory directory to the parent directory to find and so on 

            download jQuery i CNPM - S 
            
            
             // achieve interlaced color functions
             $ ( Function () { 
             $ ( . "Li: the ODD") CSS ( "background", "Red" ) 
             }) 
             in node.js, if you wrote $ const = The require ( "Jquery" ) 
         

             Since the import es6 Taiwan advanced package guide the way the browser so it can not resolve from $ Import 'Jquery' report wrong 
             so it is necessary to awaken the conversion webpack

 

Webpack configuration and operation webpack

  2 Creating webpack.config.js document are as follows in the src 

              module.exports = { 
                entry: path.join (__ dirname, './mian.js'),   // entry file using a file which to pack webpack 
                Output: { / / output related configuration 
                path: path.join (__ dirname, '. / dist'), // specify the packaged file to which the output directory (dist) go 
                 // filename: "testindex.js" // specified package good file name What is the name 
                } 
              } 


             3 so when the index was introduced in webpack we compiled js files on it
              <Script src = "../ dist / testindex.js"> </ Script>
 

             4 run webpack conversion syntax is webpack. / compiled file path ./ path of the new file this command webpack run (focus) 

             webpack./src/mian.js ./dist/testindex.js in dist in the file being compiled for testindex.js

 

  webpack can handle problems 
           webpack capable of processing interdependencies between js file 
           webpack js able to handle the compatibility problems can be loaded into es5 es6 syntax grammar  

 

We can see two ways of introducing jquery

 const $=require("Jquery")

import $ from  'jquery'
