Developing a new application for Eikon?

Melvis Vaz

We are planning to develop a HTML 5 application to bundle into Eikon.

I have questions regarding the JET API. I see News.js which reads data from somewhere. Is it reading the data from Eikon desktop application? Can I write my own custom for example Stocks.js which reads data. Where is the actual server logic implemented ( I mean getting data from database / any other source) ? Can I write my own JET API class and my own server logic to use with the HTML 5 UI Application?

Can my application save data too? I cannot see any code samples for this. Thanks.

Yes, it's reading from Eikon desktop thru CCF channel which in turns going to PIXL, RFA library so on to realtime infrastructure i.e. RMDS/TREP-RT.

You can write your own custom JET API class for sure like **News.js** does as a JET plugin. JET plugin isn't more than a javascript function that return a public API object. You register your plugin with **JET.extend()**, passing the name of your plugin (this name will be appended to the JET object) and your function. You can take a look at **News.js** for an example.

Regarding the data saving, please refer to Save/Load data sample page in JET demo app available from the Developer tab in Eikon menu. JET.Archive function is designed to persist data per instance of the app in a workspace in Eikon.
