Adapters and tools for Ember to work well with Sails

ember-data-sails

Adapters and tools for Ember to work well with Sails. Provides SailsSocketService, SailsRESTAdapter, SailsSocketAdapter, SailsSerializer and extends the store so that you can subscribe for records while pushing a payload.

Note: If you want to use this adapter with a version of SailsJS < 0.11.0 you have to use version 0.0.12 of this addon.

• SailsSocketService: injected in adapters, controllers and routes on sailsSocket property, it allow you to do Ember friendly requests using Sails socket. Example:

  // in app/controllers/application.js
  this.sailsSocket.request('get', '/someController/someAction', {name: 'Huafu'}})
    .then(function(response) {
      // do something with the response
    });

  It'll use by default the sails.io.js located at <hostname>:1337/js/dependencies/sails.io.js, but you can change this using configuration in config/environment.js file:

  ENV.APP = {
    // if you want some useful debug information related to sails
    SAILS_LOG_LEVEL: 'debug',
    emberDataSails:  {
      // default is to use same host and port as the ember app:
      host: '//localhost:1337',
      // this is the default and is the path to the sails io script:
      //scriptPath: '/js/dependencies/sails.io.js'
    }
  }

  Also don't forget to add the rules for CSP:

  // allow to fetch the script
  ENV.contentSecurityPolicy['script-src'] += ' http://localhost:1337';
  // allow the websocket to connect
  ENV.contentSecurityPolicy['connect-src'] += ' http://localhost:1337 ws://localhost:1337';

• DS.SailsSocketAdapter: use this adapter when you want to use sockets for your model(s)

• DS.SailsRESTAdapter: use this adapter when you want to use sockets for your model(s)

• DS.SailsSerializer: used by default when you use a Sails adapter, you shouldn't need to access it but it's there in case

• DS.Store.pushPayload([type], payload, [subscribe=false]): as the original one from Ember Data, except it accepts an additional parameter which, when set to true, will tell the socket adapter to subscribe to the pushed records (see below)

• DS.Store.subscribe(type, ids): tells the sails socket adapter to subscribe to those models (see below)

Installation

• npm install --save-dev ember-data-sails

CSRF config

• If you want to use CSRF token with the REST adapter, don't forget that you'll need to setup it as an object (and not true only) in the SailsJS config file (thanks @tibotiber for figuring this out).

Using

You must set sails.config.blueprints.pluralize to true in your Sails API to make the adapters works

• The SailsSocketService is injected on all adapters, controllers and routes on the sailsSocket property

• To use the SailsSocketAdapter as the default adapter, or as a model specific adapter, extend it from SailsSocketAdapter:

  // file: app/adapters/application.js
  import SailsSocketAdapter from 'ember-data-sails/adapters/sails-socket';
  
  export default SailsSocketAdapter.extend({
    /**
     * Whether to use CSRF tokens or not
     */
    useCSRF:              true,
    /**
     * Whether to group multiple find by ID with one request with a `where`
     */
    coalesceFindRequests: true,
    /**
     * The namespace of your API
     */
    namespace:            'api/v1',
    /**
     * If you want to use https://github.com/mphasize/sails-generate-ember-blueprints,
     * you need to override the default serializer to be used
     */
    defaultSerializer: '-rest',
  });

• To use the SailsRESTAdapter as the default adapter, or as a model specific adapter, extend it from SailsRESTAdapter:

  // file: app/adapters/application.js
  import SailsRESTAdapter from 'ember-data-sails/adapters/sails-rest';
  
  export default SailsRESTAdapter.extend({
    /**
     * The host of your API
     */
    host:                 'localhost:1337',
    /**
     * The namespace of your API
     */
    namespace:            'api/v1',
    /**
     * Whether to use CSRF tokens or not
     */
    useCSRF:              true,
    /**
     * Whether to group multiple find by ID with one request with a `where`
     */
    coalesceFindRequests: true
  });

• NEW - Since 0.0.11 you can ask the API to subscribe to some models, useful when you want for example to preload some data at the application start from some serialized JSON in a <meta> tag. While it's easy to push data into the store with store.pushPayload, then the records are not subscribed until you save them or get them again from Sails using the socket adapter. To push a payload and automatically subscribe to the pushed records, you can give an additional parameter to pushPayload method of the store which if true will automatically subscribe the models and records it can. This will use subscribeMethod, and subscribePath properties of the adapter to do a request on the API.

  • subscribeMethod: get, post, ... defaults to post

  • subscribeEndpoint: the endpoint to do the request on, defaults to /socket/subscribe

  • Of course you'll need to create a basic controller in your Sails API. Here is an example:

    // api/controllers/SocketController.js
    module.exports = {
      subscribe: function (req, res, next) {
        var ids, data = req.allParams(), model, subscribed = {};
        for (var name in data) {
          if (data.hasOwnProperty(name)) {
            model = sails.models[name];
            if (model) {
              ids = data[name];
              model.subscribe(req, ids);
            }
            else {
              sails.logger.warn('trying to subscribe to unknown model: ' + name);
            }
          }
        }
        res.json({});
      }
    };
    

TODO

• Write more and fix unit tests!!!
• Auto re-subscribe to subscribed records/models after a connection reset (it's already automatically re-listening for the events on the socket, but if Sails application have rebooted, we need to re-subscribe on the server somehow with the client socket)

Authors

While this was first inspired from ember-data-sails-adapter, it has now been fully re-written, with a totally different approach, and, as of the day this was written, with more features.
