Routes display incorrect when custom wrap response

[tao12345666333]

When I custom wrap response, the server index routes display incorrect.

My server.js code

var jsonServer = require('json-server')
var server = jsonServer.create()
var router = jsonServer.router('db.json')
var middlewares = jsonServer.defaults()

server.use(middlewares)
server.use(router)

server.listen(3000, function () {
  console.log('JSON Server is running')
})

router.render = function (req, res) {
  res.jsonp({
    body: res.locals.data,
    code: 0,
    msg: '',
  })
}

The response is correct.

But when I open http://127.0.0.1:3000 the page display:

My env is:

(Tao) ➜  api git:(master) ✗ json-server --version
0.8.17
(Tao) ➜  api git:(master) ✗ node --version
v6.2.1

Thanks for your json-server.

Hi @tao12345666333,

Good catch, it's a bug here:
https://github.com/typicode/json-server/blob/master/src/server/router/index.js#L48

next() shouldn't be called, instead db state should be returned immediately (res.jsonp(state)) to avoid going through the custom wrapper.

Do you want to make a PR?

Yes, I will do it.
