node.js - usando - ¿Cómo puedo dividir mis rutas koa en archivos separados?

npm

Question

Estoy tratando de averiguar cómo dividir mis rutas en archivos separados.

Tengo esto hasta ahora, pero no funciona. Me acabo de encontrar Not found cuando intento acceder a http://localhost:3001/api/things

//server.js
var koa = require(''koa'');
var app = koa();
var router = require(''koa-router'');

app.use(router(app));
require(''./routes'')(app);


// routes.js
module.exports = function *(app){
  app.use(''/api/things'', require(''./api/things''));
};


// api/things/index.js

var Router = require(''koa-router'');
var router = new Router({
  prefix: ''/api/things''
});

router.get(''/'', function *(){
  this.body = [{ name: ''Foo''}, { name: ''Bar'' }];
});

module.exports = router;

Answer 1

server.js

var app = require(''koa'')();
var router = require(''./routes'');
app.use(router.routes());
app.use(router.allowedMethods());
app.listen(3000);

rutas.js

var router = require(''koa-router'')();
router.get(''/'', function* () {
    this.body = ''router test'';
});
module.exports = router;

Answer 2

Algo como esto debería funcionar:

// app.js
var koa = require(''koa''),
    app = koa();

require(''./routes1'')(app);
require(''./routes2'')(app);

app.listen(3000);

// routes1.js
var Router = require(''koa-router'');
function register (app) {
  var router = new Router({
    prefix: ''/api''
  });
  router.get(''/'', ...); // responds to "/api"
  router.get(''/messages'', ...); // responds to "/api/messages"
  app.use(router.routes());
  app.use(router.allowedMethods());
}

module.exports = register

// routes2.js
var Router = require(''koa-router'');
function register (app) {
  var router = new Router();
  router.get(''/'', ...); // responds to "/"
  app.use(router.routes());
  app.use(router.allowedMethods());
}

module.exports = register

Answer 3

Enfoque minimalista que creo que TJ tuvo en cuenta cuando lo hizo

koa, koa-ruta, koa-mount

Enfoque con pequeñas aplicaciones independientes que se montan de la manera que más te guste:

index.js

var app = require(''./app'')
app.listen(3000);

app.js

const Koa = require(''koa'')
const _ = require(''koa-route'')
const mount = require(''koa-mount'')
const app = new Koa()
const pets = require(''./pets'')

// sub apps
app.use(mount(''/pets'', pets))

// root app
app.use(_.get(''/'', function(){
  this.body = "hello";
}))

module.exports = app;

mascotas.js

var Koa = require(''koa'');
var _ = require(''koa-route'');
var app = new Koa();


app.use(_.get(''/'', ctx => ctx.body = "pets" ));
app.use(_.get(''/:name'', (ctx, name) => ctx.body = "pet: "+ name));

module.exports = app;

Answer 4

Esto es lo que terminé yendo con:

//server.js
''use strict'';

var koa = require(''koa'');
var app = koa();
var serve = require(''koa-static'');
var path = require(''path'');
var router = require(''koa-router'');
var cfg = require(''./config'');
var mw = require(''./middleware'');

app.use(serve(path.resolve(__dirname, ''../client'')));
app.use(mw.requestTime(''Response-time''));
app.use(router(app));
app.use(cfg.db.connect);

require(''./routes'')(app);

app.get(''/api'', function *(){
  this.body = ''Welcome to API v1'';
});

app.use(cfg.db.close);
app.listen(cfg.env.port);



//routes.js
module.exports = function (app){
  app.use(require(''./api/things'').routes());
};


// api/things/index.js
var Router = require(''koa-router'');

var router = new Router({
  prefix: ''/api/things''
});

var ctrl = require(''./controllers'');

router.get(''/'', ctrl.list);
router.get(''/:id'', ctrl.get);
router.post(''/'', ctrl.post);
router.put(''/:id'', ctrl.put);
router.del(''/:id'', ctrl.del);

module.exports = router;


// api/things/controllers.js

var r = require(''rethinkdb'');
var http = require(''http'');
var parse = require(''co-body'');
var ctrl = module.exports = {};

ctrl.list = function *(next){
};

ctrl.get = function *(next){
};

ctrl.post = function *(next){
};

ctrl.put = function *(next){
};

ctrl.del = function *(next){
};

Para cualquiera que lea esto, que tenga curiosidad sobre cómo hacerlo en Koa 2.X:

app.js

import Koa from ''koa''
import rootRouter from ''./routes/root''
import userRouter from ''./routes/user''

const app = new Koa()

app.use(rootRouter.routes())
app.use(rootRouter.allowedMethods())
app.use(userRouter.routes())
app.use(userRouter.allowedMethods())

export default app

rutas / root.js

import Router from ''koa-router''
const router = new Router()

router.get(''/'', async (ctx, next) => {
  ctx.body = ''Hello''
})

export default router

rutas / usuario.js

import Router from ''koa-router''
const router = new Router({ prefix: ''/user'' })

router.get(''/'', async (ctx, next) => {
  ctx.body = ''Some User''
})

export default router

Si desea evitar la repetición con las routes() y los allowedMethods() , puede usar koa-compose para componer el middleware juntos. Para simplificar, hice una wrapper alrededor de él para simplificar el trabajo con koa-router . Usándolo se vería algo como esto:

app.js

import Koa from ''koa''
import router from ''./routes''

const app = new Koa()

app.use(router())

export default app  

rutas / index.js

import combineRouters from ''koa-combine-routers''
import rootRouter from ''./root''
import userRouter from ''./user''

const router = combineRouters(
  rootRouter,
  userRouter
)

export default router

Y haría lo mismo.
