Angularjs Application concerns?

Hi,

I am taking a shot at to make an angularjs application which is essentially taken care of ongoing exchange from diffrent vendors.Actually our Payment exchange application is as of now made in asp.net and running and now to keep quick execution in the mind we are changing over this application in angularjs with web programming interface bolster.

My fundamental concern is the security of the application as it is essentially managing exchanges.

In our old application every one of the things is dealt with throung session yet as we probably am aware in web programming interface session isn’t upheld by default.By we have endured custom class.

It would be ideal if you manage me here …Is the desicion is correct or I get issue in prospects.

Thank you
