首先安装 Node.js 以及 NPM,可以参考这篇文章。
1 初始化配置
从命令行进入工程所在文件夹,输入以下命令,初始化配置:
npm init
运行结果:
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.
See `npm help json` for definitive documentation on these fields
and exactly what they do.
Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.
package name: (webpack) deniro
version: (1.0.0)
description: deniro's demo
entry point: (main.js)
test command:
git repository:
keywords:
author: deniro
license: (ISC)
About to write to F:\WebstormProjects\xxx\webpack\package.json:
{
"name": "deniro",
"version": "1.0.0",
"description": "deniro's demo",
"main": "main.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "deniro",
"license": "ISC"
}
Is this ok? (yes) yes
配置过程中,会让我们输入一些配置项内容,我们可以根据实际的项目选项进行配置。最后键入 yes
。npm 会在该工程目录下生成一个 package.json 文件,文件内容就是之前命令所设定的那些配置项。
2 安装 Webpack
命令行下,在同一个工程文件夹下,输入以下命令:
npm install webpack --save-dev
--save-dev
表示会为开发模式下载相应的依赖包。
安装过程:
运行结果:
安装成功后,会在 package.json 中新增 webpack 配置:
"devDependencies": {
"webpack": "^4.29.5"
}
3 安装 webpack-dev-server
webpack-dev-server 可提供启动服务器、热更新以及接口代理等服务。
npm install webpack-dev-server --save-dev
运行结果:
安装成功后,也会在 package.json 中新增 webpack-dev-server 配置:
"devDependencies": {
"webpack": "^4.29.5",
"webpack-dev-server": "^3.2.0"
}
至此,Webpack 安装成功O(∩_∩)O~
