安装
1.全局:
npm install -g webpack
2.项目:
npm install webpack --save-dev
3. 添加 content.js
module.exports = 'It workd from content.js'
4. 添加入口文件 entry.js
console.log(require('./content.js'))5. 编译文件打包
webpack ./entry.js bundle.js
6. index.html引入 bundle.js
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"></head><body><script src="bundle.js"></script></body></html>
7. 查看结果
输出
It workd from content.js
使用Loader加载css
webpack默认只支持js模块, 要打包css文件需要使用 css-loader处理css文件, style-loader应用样式
npm install css-loader style-loader
1 新建 style.css
body { background-color: yellow;}2 入口文件引入 style.css
console.log(require('./content.js'))require('!style!css!./style.css')3 重新编译, 打开html文件, 样式已经加载
绑定Loader
require('!style!css!./style.css')每次都写很长的加载器前缀很麻烦, 可以在编译命令指定加载器绑定到文件后缀名
webpack ./entry.js bundle.js --module-bind "css=style!css"
此时 entry.js可以简化
require('./style.css')配置文件
将配置信息添加到 webpack.config.js配置文件后, 每次只需要执行 webpack即可完成打包任务
module.exports = { entry: './entry.js', output: {}}
