add wasm and watch the whole project burn

[SaintMercury]

Adds wasm-bindgen and also doesn't work :)

[SaintMercury]

this might be unnecessary. Can't remember adding it, must've done so in the other repo

Relevant issues and PR for possible solutions to errors

[Greatness7]

I recommend working off the dev branch if possible. It's got a lot of changes and improvements. I plan to merge it into main eventually.

Besides that, since serde support is already implemented there, I don't think you actually need to decorate every struct with #[wasm_bindgen] and can instead just let serde_wasm_bindgen do it for you.

Example:

[dependencies]
wasm-bindgen = "^0.2"
serde = "^1.0"
serde-wasm-bindgen = "^0.6"
js-sys = "^0.3"
web-sys = "^0.3"

[dependencies.tes3]
git = "https://github.com/Greatness7/tes3"
branch = "dev"
default-features = false
features = ["esp", "nightly", "serde"]

use js_sys::Uint8Array;
use serde_wasm_bindgen::{from_value, to_value};
use tes3::esp::Plugin;
use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn load_objects(array: Uint8Array) -> Result<JsValue, JsValue> {
    let mut plugin = Plugin::new();
    plugin
        .load_bytes(array.to_vec().as_ref())
        .map_err(|e| JsValue::from(e.to_string()))?;

    let value = to_value(&plugin.objects)?;

    Ok(value)
}

#[wasm_bindgen]
pub fn save_objects(value: JsValue) -> Result<Uint8Array, JsValue> {
    let mut plugin = Plugin {
        objects: from_value(value)?,
    };

    let bytes = plugin
        .save_bytes()
        .map_err(|e| JsValue::from(e.to_string()))?;

    let length = u32::try_from(bytes.len()) //
        .map_err(|e| JsValue::from(e.to_string()))?;

    let array = Uint8Array::new_with_length(length);
    array.copy_from(&bytes);

    Ok(array)
}
