At my work, we distribute our application through SDK for all channels (Web, iOS, Android). We have the current codebase in three different languages and implementing a new feature requires making changes in all three.

The application does not use any specific native component, and handles a large amount of networking through websockets.

Want to understand, what are the tradeoffs in building a JS based SDK for all devices. Which framework is being used in enterprises to distribute SDK's? Any pitfalls in using one vs the other.

Thanks in advance!
