webpack.02-如何打包

在空文件夹初始化：CMD

npm init -y

-y意思是所有yes

cnpm install -D webpack webpack-cli

文件结构

src（文件夹）--->index.js 

console.log('hello webpack')

test（文件夹）--->main.js   

console.log('hello webpack2')

package.json

scripts里面加上build:webpack
webpack默认是打包src下面的index.js 能够自定义，如：build:webpack server/index.js

{
  "name": "02",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack",
    "build2": "webpack test/main.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "^4.43.0",
    "webpack-cli": "^3.3.11"
  }
}

打包：CMD

npm run build
npm run build2
