手动生成bundle.js文件
./node_modules/.bin/webpack src/index.js dist/bundle.js
新建webpack.config.js文件
touch webpack.config.js
目录结构
webpack-demo
|- package.json
|- webpack.config.js
|- /dist
|- index.html
|- /src
|- index.js
webpack.config.js代码
const path = require('path');
module.exports = {
entry: "./src/index.js",
output: {
filename: "bundle.js",
path: path.resolve(__dirname, 'dist')
}
}
./node_modules/.bin/webpack --config webpack.config.js
脚本化命令：修改package.json，添加
“scripts”: {
"build": "webpack"
}
npm run build 替代之前的命令行
