WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.

Component communication might deserve a dedicated page.

Ancestor -> Descendant

straightforward: passing props. Using a context if the descendants can be too deep down the tree.

Descedant -> Ancestor

This is not very obvious. In fact, two people asked the same question on Discord in one day. And personally, I had no clue either despite h

Problem:
After using Engine.createTextureFromKtx/jpeg/Png, I need to query the texture width and height so I can generate proper UV coordinates for font display.

Proposed solution
Expose the Texture.getWidth(), getHeight(), etc. methods to get texture information. I currently only need width and height, but I can see usage cases for many of the other "getters" available in the C++ in

  • copy/v86#431
  • copy/v86#333 (add a mute button and/or fix the "requires a gesture" warning). A volume selector would also be nice.
  • There's a minor issue where holding down and moving the mouse on the screen selects text outside of the screen on Firefox
  • Retry XHR requests that fail with 5xx or time out, with exponential backoff
  • Add configuration via url parameters (https://

In bytecodealliance/wasmtime#2497 (comment) we added support for generating nested modules, and we generate these modules by concatenating strings of WAT and then passing it to Module::new which internally checks for WAT strings and assembles them into Wasm bytes if necessary.

We can make this more efficient, improving the number of test cases we fuzz in a

Current behavior

Exception occurred: System.ArgumentException: Provided filter string is not valid. Filter string should contain a description of the filter, followed by a vertical bar and the filter pattern. Must also separate multiple filter description and pattern pairs by a vertical bar. Must separate multiple extensions in a filter pattern with a semicolon. Example: "Image files (*.bm

Motivation

I am using the following pattern to efficiently initialize a large buffer inside wasm memory from JavaScript without copies (see #1079 for full motivation):

#[wasm_bindgen]
pub struct WasmMemBuffer {
    buffer: Vec<u8>,
}

#[wasm_bindgen]
impl WasmMemBuffer {
    #[wasm_bindgen(constructor)]
    pub fn new(byte_length: u32, f: &js_sys::Function) -> Self {

Related to metering wasm3/wasm3#127 and being able to run a set number of instructions, I'd like to be able to serialize a paused interpreter's state and deserialize it to a new interpreter instance; very roughly,

const interp = new wasm3.Interpreter(module);
interp.interpretNInstructions(100);
const interpState = interp.serializeState();
const interp2 = wasm3.In
