Koa2使用koa-combine-routers路由拆分成多文件
一般路由可能会遇到下面这样的用法，这属于常规用法，但是模块多了也就不怎么好看了。
app.use(home.routes())
app.use(home.allowedMethods())
app.use(users.routes())
app.use(users.allowedMethods())
假设我们有两个路由模块分别为 home、users 首先新建文件夹 routes,并在 routes 文件夹下新建 home.js、user.js、index.js
routes/home.js
const Router = require('koa-router')
const router = new Router()
router.prefix('/home')
router.get('/', async (ctx, next) => {
ctx.body = 'Hello home'
})
module.exports = router
routes/user.js
const Router = require('koa-router')
const router = new Router()
router.prefix('/user')
router.get('/', async (ctx, next) => {
ctx.body = 'Hello User'
})
routes/index.js
const glob = require('glob')
const { resolve } = require('path')
const combineRouters = require('koa-combine-routers')
let registerRouter = () => {
return glob.sync(resolve(__dirname, './', '**/*.js')).reduce((pre, cur) => {
if (cur.endsWith('/index.js')) return pre
let routerModule = require(cur)
return [...pre, routerModule]
}, [])
}
const router = combineRouters(registerRouter())
module.exports = router
routes/index.js
const Koa = require('koa')
const app = new Koa()
const registerRouter = require('./routes')
app.use(registerRouter())
app.listen(3000)
