SitePen is excited to announce Stocker, which demonstrates some of the more advanced capabilities of Dojo, including the newly released DataChart, the DataGrid, Data Store, Comet, Persevere, and BorderContainer. SitePen is also offering a one-day workshop where you will learn how to create Stocker yourself, but I’m here to give you a sneak peak of what Stocker is and how it works.
Stocker uses these technologies to emulate a stock monitoring application. We’re using made up data, but that’s actually more interesting. The Persevere server generates new stock items at certain intervals, and then pushes them to the browser with Comet. Then the Data Store updates its items and triggers an onSet notification. The DataGrid and DataChart are both connected to the same store, and are listening to that event. They then update their displays and show the stock items and their latest data.
