Devev is written in TypeScript and the TypeScript compiler is open source so I’m able to leverage it directly. That, in addition to the GitHub project ts-simple-type takes care of most of my difficulties.

However, I don’t support generics as first class citizens in the node editor yet and probably won’t for V1. I can detect that an input/output is a generic but I convert it to any before use.

If your project is based on an existing language I’d recommend taking a look at injesting compiler tools if they are open source.
