由于系统业务比较复杂，微前端（多页应用）实现期望用一个app一个webpack的形式，这样可以更好隔离，而且每个app的webpack config可以定制。
Nginx在前端项目中安装比较麻烦，所以考虑用nodejs来代理，社区比较成熟的node代理显然就是express的http-proxy-middleware了：
var express = require('express')
var proxy = require('http-proxy-middleware')
var rewrite = require('express-urlrewrite')
var app = express()
let options = {
'/report/template': {
target: 'http://www.wenming.cn',
pathRewrite: {
'^/report/template': '',
},
headers: {
"Host": "www.wenming.cn",
"Connection": "keep-alive",
"Cache-Control": "max-age=0",
"Upgrade-Insecure-Requests": "1",
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36",
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3",
"Accept-Encoding": "gzip, deflate",

}
},
'/report':{
target: 'http://localhost:8090',
pathRewrite: {
'^/report': '',
},
}
}
app.use('/app/home', (req,res,next) => {
req.originalUrl = req.originalUrl.replace(/^\/app\/home/, '')
next()
});
app.use(rewrite('/app/home/*', '/$1'))
function proxyFactory(source, option) {
app.use(source, proxy(option))
}
for (let key in options) {
proxyFactory(key, options[key])
}
app.use('/', (req, res) => {
res.send('not found!!')
})
app.listen(3000)
webpack-dev-server同时起多个：
const execa = require('execa')
execa('webpack-dev-server', ['--entry', './apps/alarm.js', '--port', '8044', '--config', './webpack.js'], {stdio: 'inherit'})
execa('webpack-dev-server', ['--entry', './apps/report.js', '--port', '8045', '--config', './webpack.js'], {stdio: 'inherit'})
