在开始之前,请确保安装了 Node.js 的最新版本。
.
+-- src
| +-- bar.js
| +-- index.js
+-- index.html
+-- webpack.config.js
export default function bar() {
}
import bar from ‘./bar‘;
bar();
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<script src="dist/bundle.js"></script>
</body>
</html>
const path = require(‘path‘); //node内置的模块,用来设置路径
// 因为我们整个js文件被node封装在一份方法中运行。__dirname是node调用方法时传递进来的,表示当前目录。
module.exports = {
entry: ‘./src/index.js‘, //entry 配置当前项目的入口文件
output: { //output 配置输出
path: path.resolve(__dirname, ‘dist‘), //输出的文件名
filename: ‘bundle.js‘ //输出的路径 resolve拼接一个目录
}
};
进入项目根目录,执行命令:
npm init
执行此命令,生成package.json文件,此时的目录结构如下:
.
+-- src
| +-- bar.js
| +-- index.js
+-- index.html
+-- webpack.config.js
+-- package.json
安装 webpack 依赖
npm install webpack webpack-cli --save-dev
缩写形式安装 webpack
npm i webpack webpack-cli -D
# –save:模块名将被添加到dependencies,可以简化为参数-S。
# –save-dev: 模块名将被添加到devDependencies,可以简化为参数-D。

生成dist文件夹及bundle.js,如下:
