Cool, I started working on something similar a while back but I didn't get past handling generics. Like if you have a node<T> with two T inputs and a T[] output, then when you attach a number to an input, the other input's type becomes number too and the output becomes number[]. That could need to propagate to connected nodes, too. Also when you disconnect a node, you would want to determine whether T must still be a number.

Is that something you're handling in your project? Do you have any pointers?

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.
