首先这是需要安装的包
然后看dev.server里的代码
const express = require("express")
const webpackDevMiddleware = require("webpack-dev-middleware")
const webpack = require("webpack")
let webpackConfig = require("../config/dev.config")
const path = require('path')
let config = require('../config')
const app = express()
const open = require('open')
process.env.NODE_ENV === 'mock' && require('../mock/data')(app)
require('../config/proxy')(app) // 代理
let compiler = webpack(webpackConfig)
app.use(require("webpack-hot-middleware")(compiler));//固定写法
app.use(path.posix.join(config.dev.assetsPublicPath, config.dev.assetsSubDirectory), express.static('./static')) // 当所有/static这个下的请求
都转到static目录
app.use(webpackDevMiddleware(compiler, {
publicPath: config.dev.assetsPublicPath
}))
app.listen(config.dev.port, function (res) {
console.log(`Listening on port ${config.dev.port}!`)
process.env.NODE_ENV !== 'mock' && open(`http://localhost:${config.dev.port}/#/index`)
})
之所以叫简版，是因为去除了一些花哨或者用处不大的东西，比如运行命令行的颜色，以及进度百分比等等
首先要搭建，必然需要一个服务器，这里为什么不选自带的webpack-dev-server，因为webpack-dev-server定制性差，比如我要改个端口，要在script里面改不能变量，
所以这里选择express做服务器，
webpack-dev-middleware是webpack为expres服务器提供的中间件，再说白了，就是让express的服务器支持热更新和缓存的(配合webpack-hot-middleware)
然后是proxy里的代码
const proxy = require('http-proxy-middleware')
const preA = require('./http_prefix').preA
const tables = [{
proxy: preA,
target: ''
}]
module.exports = (app) => {
for (let i = 0; i < tables.length; i ++) {
app.use(tables[i].proxy, proxy({
target: tables[i].target,
changeOrigin: true
}))
}
}
// 遍历代理的接口
然后我们看下config下面的index.js文件是什么以及dev.config文件是什么
const path = require('path')
const webpack = require('webpack')
const merge = require('webpack-merge')
const base = require('./base.config')
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = merge({
entry: ['webpack-hot-middleware/client?path=/__webpack_hmr&timeout=20000','babel-polyfill','./src/main.js'], //需要热更新的配置
output: {
path: '/',这个这里作用不大build时候作用对应文件位置
filename: '[name].js'
},
module: {
rules: [
{
test: /\.less$/,
loaders: ['style-loader','css-loader?modules&localIdentName=[local]-[hash:base64:5]', 'less-loader', 'postcss-loader']
},
{
test: /\.scss$/,
loaders: ['style-loader','css-loader', 'sass-loader', 'postcss-loader']
},
]
},
plugins: [
new webpack.LoaderOptionsPlugin({
options: {
eslint: {
formatter: require('eslint-friendly-formatter')
}
}
}),
new webpack.HotModuleReplacementPlugin(),
new HtmlWebpackPlugin({
filename: 'index.html',
template: 'index.html',
inject: true // 打包好的js文件是插入到body还是body尾部
})
],
devtool: 'eval-source-map',
}, base)
const path = require('path')
module.exports = {
build: {
assetsSubDirectory: 'static',
assetsPublicPath: '/',
assetsRoot: path.resolve(__dirname, '../dist')
},
dev : {
assetsSubDirectory: 'static',
assetsPublicPath: '/',
port: 3020,
}
}
就是一些当本地运行或者生产时候对应的配置
