Koa使用require-directory实现路由的自动加载

const Koa = require('koa');
const app = new Koa();

const requireDirectory = require('require-directory');
const Router = require('koa-router');
const modules = requireDirectory(module,'./api',{
    visit:whenLoadModule
})

function whenLoadModule(obj){
    if(obj instanceof Router){
        app.use(obj.routes())
    }
}

app.listen(3000);

const Router = require('koa-router');


const router = new Router();

router.get('/v1/book/latest',(ctx,next)=>{
    ctx.body={key:'books'}
    
})

module.exports = router
