How to use a custom Express server with Ember CLI?

问题:

I'm using Ember CLI 0.0.36. When I run ember server in my project folder, my understanding is that a server buried in some Brocoli process gets started. However I would like to program a custom Express server and have my app point to that Node.js code for its backend. How would I go about doing that within the Ember CLI framework?

UPDATE:

Following @user3155277's answer, I added an adapter file like so:

app-name/app/adapters/application.js:

import DS from 'ember-data';  export default DS.RESTAdapter.reopen({ namespace: 'api' }); 

I created an Express server that I put at the root of my app:

app-name/server.js:

var express = require("express"),     app = express(),     path = require("path");  app.get("/api/test", function(req, res) {     res.json({         hello: "world"     }); });  var server = app.listen(8147); 

In the Ember app, my index route is defined as so:

app-name/app/routes/index.js:

import Ember from 'ember';  export default Ember.Route.extend({     model: function() {         return Ember.$.getJSON("/api/test").then(function(data) {             return data;         });     } }); 

On the command line I then start the server like so:

ember serve --proxy http://localhost:8147/ 

I get the following error:

version: 0.0.35-master-86abdb11ba Proxying to http://localhost:8147/ object is not a functionTypeError: object is not a function     at Class.module.exports.Task.extend.start (D:\ember-cli\lib\tasks\server\express-server.js:41:43)     at Class.module.exports.Task.extend.run (D:\ember-cli\lib\tasks\serve.js:40:23)     at Class.module.exports.Command.extend.run (D:\ember-cli\lib\commands\serve.js:35:18)     at Class.Command.validateAndRun (D:\ember-cli\lib\models\command.js:74:15)     at CLI.

This is actually pretty simple with Ember CLI 0.0.40:

Create folder structure

ember new my-app 

Go into the newly created folder

cd my-app 

Generate api-stub* (see update)

ember generate api-stub my-server 

This latter command creates a server folder with an index.js file and a routes folder with a my-server.js file.

Open my-server.js file and you see:

module.exports = function(app) {     var express = require("express");     var myServerRouter = express.Router();     myServerRouter.get("/", function(req, res) {         res.send({my-server:"something"});     });     app.use("/api", myServerRouter); }; 

All you need to do then is to change that file. If the Ember app makes calls to /api/hamsters and /api/project, edit as follows:

module.exports = function(app) {     var express = require("express");     var myServerRouter = express.Router();     myServerRouter.get("/hamsters", function(req, res) {         res.send({ ... });     });     myServerRouter.get("/project", function(req, res) {         res.send({ ... });     });     app.use("/api", myServerRouter); }; 

To start the server (from project's root):

ember server 

Make sure you have updated node.js to the latest version as well.

Updates

As of Ember CLI 0.0.41 (via this PR) api-stub has been renamed http-mock.

I started playing with ember cli so i'm not sure but i found the following: https://github.com/dockyard/ember-cli-plus-backend/tree/rails-served-html/frontend/api-stub Basically you should proxy your express server to the same port as your ember-cli (so then you don't have to deal with jsonp issue)

Set the method to 'proxy' and define the proxyURL to pass all API requests to the proxy URL.

UPDATE:

1.Generate adapter ember generate adapter application

2.Make api namespace - fill the created file with the following code:

export default DS.RESTAdapter.reopen({ namespace: 'api' });

3.Start the server with ember serve --proxy http://localhost:1337/ (this will proxy all your request to localhost:4200 to 1337

4.Make routes in your express app prefixed by /api

Hope it helps
