windows 使用npm安装webpack 4.0

本文详细介绍NodeJS的安装步骤及验证方法,并演示如何通过命令行工具创建Webpack项目,包括安装Webpack及其CLI工具,设置npm脚本以启动Webpack。

1、安装NodeJS

首先需要安装nodejs点击如下链接

https://nodejs.org/en/download/点击打开链接


选择Windows Installer点击下载,下载完成之后点击安装包进行安装,


点击运行


点击next


点上√,然后点击Next


选择安装目录


点击change选择安装目录


将Fold name 改为d:\Program Files\nodejs\ 点击OK


点击Next


点击Next


点击install


点击Finish,nodejs安装完成

使用win+r打开cmd窗口或者点击开始搜索cmd打开窗口


输入cmd点击打开


输入node -v 出现nodejs版本号

输入npm -v 出现npm版本号则安装npm安装成功,

2、安装webpack

桌面新建一个webpack-test文件夹,点击进入文件webpack-test夹 按下shift+鼠标右键  点击在此处打开命令窗口


输入npm init 一直点击回车键 当出现Is this ok?时 输入yes,然后点击回车键


进入webpack-test文件夹,出现package.json文件


使用notepad++打开package.json

{
  "name": "webpack-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

回到cmd窗口,输入 npm install --save-dev webpack


这时候使用 webpack -v 会出现'webpack' 不是内部或外部命令,也不是可运行的程序或批处理文件。

继续输入  npm install --save-dev webpack-cli

                npm install --global webpack

                npm install --global webpack-cli


使用webpack -v 出现版本号则安装成功


使用webpack 命令 出现错误ERROR in Entry module not found: Error: Can't resolve './src' in 'C:\Users\Administrator\Desktop\webpack-test'


错误原因是webpack入口默认为src/index.js  进入webpack-test文件夹新建文件夹 src,进入src文件新建index.js



在index.js中写入内容

    alert("webapck test");

然后回到cmd窗口输入webpack


打包成功 但是还有一个警告 WARNING in configuration The 'mode' option has not been set. Set 'mode' option to 'development' or 'production' to enable defaults for this environment.是因为使用webpack没有指定mode为 development(开发模式)或者为production(生产模式)


也可以在package.json文件中加入

"scripts": {
  "dev": "webpack --mode development",
  "build": "webpack --mode production"
},

最终package.json文件内容为

{
  "name": "webpack-test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "scripts": {
	  "dev": "webpack --mode development",
	  "build": "webpack --mode production"
  },
  
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "^4.0.1",
    "webpack-cli": "^2.0.10"
  }
}

然后使用 npm run dev (相当于 webpack --mode development )或者

使用npm run build(相当于 webpack --mode production)

接下开看一下开发模式和生产模式的区别

我们首先看一下开发模式,回到cmd窗口 输入 npm run dev


进入webpack-test文件夹,发现自动生成了一个dist文件夹,这是webpack默认输出文件位置


进入dist文件夹 发现出现一个main.js 这是webpack默认输出的js文件


使用notepad++ 打开main.js 内容如下 js文件为正常开发时的格式

/******/ (function(modules) { // webpackBootstrap
/******/ 	// The module cache
/******/ 	var installedModules = {};
/******/
/******/ 	// The require function
/******/ 	function __webpack_require__(moduleId) {
/******/
/******/ 		// Check if module is in cache
/******/ 		if(installedModules[moduleId]) {
/******/ 			return installedModules[moduleId].exports;
/******/ 		}
/******/ 		// Create a new module (and put it into the cache)
/******/ 		var module = installedModules[moduleId] = {
/******/ 			i: moduleId,
/******/ 			l: false,
/******/ 			exports: {}
/******/ 		};
/******/
/******/ 		// Execute the module function
/******/ 		modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);
/******/
/******/ 		// Flag the module as loaded
/******/ 		module.l = true;
/******/
/******/ 		// Return the exports of the module
/******/ 		return module.exports;
/******/ 	} ......

然后看一下生产模式,回到cmd窗口 输入 npm run build


进入webpack-test/dist,然后再打开main.js,发现内容格式非常紧凑,适合生产环境下使用


我们在webpack-test目录下新建一个index.html,引入main.js看是否可用


index.html内容为 保存之后点击index.html使用浏览器打开

<!DOCTYPE html>
<html>
<head>
    <title>webpack-test</title>
    <script type="text/javascript" src="./dist/main.js"></script>
</head>
<body>
    
</body>
</html>

我使用的chrome浏览器 打开效果为下图,说明index.js打包成功

至此webpack安装完成,至于后面应用配置还要更加繁琐,根据个人需求可以在官方文档参考如何配置
