You can certainly do this.  Of course that means you have to maintain it for versioning and such.  I am also not sure on the legal licensing issues here if that is something that is a risk for you.  After all it is the content of the file that is licensed, not the file itself.

Best of luck with X12!

Prudhvi,

The simplest answer is no.   ZEN, which has been a deprecated technology for some time, is a complete framework deeply integrated to Cache.  It relies heavily on synchronous communications which has been deprecated by, thought still available, by most browsers.  For both reasons new development should not be done using ZEN.

Angular, on the other hand, is a modern framework for Web Application development.  It is inherently asynchronous and therefore disconnected from the back-end.  As Eduard stated the typical communication methodology is for the back-end to provide a RESTful interface which are quite easy to develop and publish both direct from IRIS or via the InterSystems API Manager.

I am going to make the assumption that this is part of an existing application that you are looking do new development on.  As stated ZEN is deprecated therefore it would be a good idea to develop a roadmap to migrate from ZEN to something like Angular.  I would take this new project and use it to explore the move to Angular.

You should also note that at some unknown point in time browsers could remove support for synchronous communications.  The latter will likely not happen for quite some time as many older applications still rely on it.  Several years back one browser, Firefox I think, tried to remove this support and had to quickly backtrack as too many applications stopped working.  So you have time.
