Subject Re: Integrating a thrift javascript client sdk with angularjs
Date Wed, 19 Mar 2014 16:18:07 GMT
Hi All

@Shameera : It would be better if we come up with new javascript client in
AngularJS instead of  wraping exiting javaScript client as angular service.
We faced lot of issues last time doing this. Do you remember?

Currently I am looking into Thrift API.

Can we have a concrete plan on
1) Integrating different modules. For this we have to rewrite the
Javascript API in Angularjs.
2) writing thrift client in Angularjs


Regards
Vijayendra
