(Partially) generate Rust type & function declarations from TypeScript type definiton file or JSDoc

Of course this does not work for some types..
This might belong in another repo.

Nah definitely! I could totally see something like

wasm_bindgen_typescript!("foo.d.ts");

being used

[adiba]

I thought of it as a separate nodejs tool since the Typescript parser is a node module. I could attempt writing a provisional script, but I know nothing about macros... yet.

[adiba]

TypeScript also has modules and interfaces, which could be directly translated to Rust modules and traits with ease, so support for these would be great.

Yeah I'm not sure what the best way to do this would be. I'd naively prefer to start off with a syn-based parser (just in the procedural macro itself) rather than picking up a dependendy through node, but I'm not sure how easily that'll work.

Alternatively there could be a JS tool which takes a foo.d.ts and emits a foo.rs with #[wasm_bindgen] anntoations maybe

This is similar to https://github.com/alexcrichton/wasm-bindgen/issues/42 as well

Experimental support for this is now in the repository and future work is tracked with a label, so I'm gonna close this for now
