创建一个webpack打包流程
首先安装webpack插件
mkdir webpack-demo && cd webpack-demo
npm init -y
npm install --save-dev webpack
npm install --save lodash
创建index.html文件
<html>
<head>
<title>webpack 2 demo</title>
</head>
<body>
<script src="./dist/bundle.js"></script>
</body>
</html>
创建app/index.js文件
'use strict';
import _ from 'lodash';//加载
function component () {
var element = document.createElement('div');
/* lodash is required for the next line to work */
element.innerHTML = _.join(['Hello','webpack'], ' ');
return element;
}
document.body.appendChild(component());
建立一个webpack.config.js文件
var path = require('path');//调用path模块
module.exports = {
entry: './app/index.js',//入口
output: {
filename: './bundle.js',//输出文件
path: path.resolve(__dirname, 'dist')//输出目录
}
};
使用npm命令行执行
{
...
"scripts": {
"build": "webpack -p"
},
...
}
npm run build
package.json
{
"name": "create",
"version": "1.0.0",
"description": "mkdir webpack-demo && cd webpack-demo\r npm init -y\r npm install --save-dev webpack",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build" : "webpack -p"
},
