WASM version of the parser

Idea in one sentence

Allows developers to use Rust parser in JS world.

Current draft PR #27

[dubadub]

WebAssembly (Wasm) allows us to compile Rust parser code into a .wasm binary, which can be loaded into TypeScript using tools like wasm-bindgen and WebAssembly.instantiate, enabling TS to call Rust functions as if they were regular JavaScript functions.

I experimented a bit and have a draft PR. It can parse a recipe from TS with the help of serde-wasm-bindgen crate but because the return is just a big JS object it's not handy working with it for developers. So as next step I wanted to create wrapper objects for better dev experience and TS definitions.

I tried to do that on rust side with wasm_bindgen declarations, but it turned out bulky. Maybe we can simply define objects on TS side and rewrap response. I can give more examples if needed.

What would an appropriate end user experience be on the TS side? Under the hood, the Rust parser has all that data, but it's got convenience methods and stuff, right?

Is the result of this the link you posted, or is it something else? Trying to see what you mean by trying to use wasm_bindgen declarations being bulky.

That was my first iteration f08b9b0 with wasm_bindgen. Tbh I forgot why I decided to use serde approach, maybe respective TS classes not generated, or something. I decided to try doing minimum on rust side and handle everything in TS.

It could be just enough repeating existing (before Rust) interface to make it usable.

I don't know much about wasm_bindgen yet, but what would stop one from putting those derive macros directly in the canonical parser objects? Like, directly on Recipe and Ingredients and stuff?

Actually, it might work, I'm not sure about specific requirements it has.
