16 Koa路由进阶配置

koa-combine-routers 可以使路由分模块，目录更加清晰，容易维护

app.js

const Koa = require('koa')
const router = require('./routes')
const app = new Koa()
app.use(router())

routes.js

const arouter = require("./a")
const brouter = require("./b")
const combineRouters = require('koa-combine-routers')
module.exports =  combineRouters(arouter,brouter)

a.js

const Router= require('@koa/router')
const router=new Router()
router.get('/a',async ctx=>{
    ctx.body='from a'
})

b.js

const Router= require('@koa/router')
const router=new Router()
router.get('/b',async ctx=>{
    ctx.body='from b'
})
module.exports=router
