Lightstreamer - Basic Stock-List Demo - HTML (Ember.js) Client
View live demo
This demo displays real-time market data for ten stocks, generated by a feed simulator in a similar way to the Lightstreamer - Basic Stock-List Demo - HTML Client.
A Lightstreamer Subscription is used for subscribing to the data. The onItemUpdate callback manages the update of the model that backs the application template: once a new item event comes from the server, a lookup from the local store is performed to retrieve the matching object, in order to update its attribute values according to the modified item field values. Finally, changes applied to the model will be automatically reflected by the framework in the HTML page.
The demo includes the following client-side functionalities:
- A Subscription containing 10 items, subscribed to in MERGE mode.
In the blog post "A Simple Ember.js Demo for Lightstreamer" you can find a more in depth discussion about the integration between Ember.js and Lightstreamer.
