Are there any plans to support Typescript in node-red in the future?

Hi @therustyalex - welcome to the forums.

Could you clarify what you mean?  
Custom Nodes can already be developed in typescript (I do myself)

Thank you.

I was mainly thinking about typescript in function nodes:)

The custom nodes in Typescript is also interesting tho, is this what you are referring to:

Yes, custom Node development is fully operational in Typescript (I use it for my own nodes)

As for using it in Function nodes - I'm not sure that will be possible.  
As the Code in function nodes uses the Node JS vm environment.

[https://nodejs.org/api/vm.html#vm-executing-javascript](https://nodejs.org/api/vm.html#vm-executing-javascript)

And given typescript is not javascript (more translated to JS, before the V8 engine) - im not sure that it's possible without a mammoth task of re-writing the function node - essentially compiling it with typescript, before its passed to the VM
