Rust <-> typescript setup

  1. This needs to run on plain Linux/x86, not web assembly. The reason is that the Rust code is using OpenGL / CUDA bindings.

  2. Is there a standard way to tag certain Rust functions / structs as "TypeScript accessible", and then have a setup where:

2.a We run a typescript repl.
2.b We load the rust code as a module.
2.c We can type typescript code in the typescript repl and manipulate the Rust module ?

I don't think Node runs TypeScript natively, but if you can find a way to run a TypeScript repl with node, you can create a native NodeJS module with rust using Neon:

That would allow you to bind your native Rust code as a JavaScript library which you could interact with in a NodeJS REPL. You would just have to figure out how to work in TypeScript.

I'm currently trying to do something similar myself, including trying to access/manipulate the library from a repl (mainly to figure things out).

Neon doesn't currently generate types (related issue on github), but I was just informed in the slack channel that I could use quicktype (I guess referring to this product?) to programmatically generate types, otherwise it was suggested to just handwrite the types if the api is small enough.

You are ahead of me, so I do not know if I am understanding the problem correctly.

Quoting https://rustwasm.github.io/docs/wasm-bindgen/print.html

--typescript
Output a TypeScript declaration file for the generated JavaScript bindings. This is on by default.

--no-typescript
By default, a *.d.ts TypeScript declaration file is generated for the generated JavaScript bindings, but this flag will disable that.

I wonder if there is a wa yto make the "API crate" to also be buildable under wasm and then utilize the above to generate the *.d.ts files.
