rusty-wacc-viewer VS wasmer

While a "host" application (for the WASM runtime used) is required to enable access to graphical output (or user input) it doesn't have to be a browser.

At the (almost) most basic level a chunk of memory can be used as a framebuffer--the host application would read the pixel data which the WASM bytecode wrote and then write it to the host display via OS-level routines.

There are some plans/experiments at making a framebuffer "device" available as part of WASI.

I've written a couple of graphical WASM host applications that aren't browsers (and which don't use memory for pixel data transfer just integer values returned from a function):

The "WebAssembly Calling Card (WACC) Viewer" is implemented via the Godot game engine and an addon that integrates the Wasmtime WASM runtime with the engine: https://wacc.rancidbacon.com

(Also implemented a WACC Viewer in Rust: https://gitlab.com/RancidBacon/rusty-wacc-viewer)

WACC specifies how to transform three integer values (returned from a function in a WASM module) into a coloured triangle in order to render it on screen.

Another "host application" I implemented was a libretro compatible plugin that loads a WASM module and then feeds the module with input from libretro & retrieves framebuffer pixel data (one pixel at a time :D ) via a WASM function call & writes it to the libretro framebuffer for display.

This is awesome. I'd love to have upstream support in Wasmer ( https://wasmer.io )

WebAssembly is extremely portable. WebAssembly runs on: all major web browsers, V8 runtimes like Node.js, and independent Wasm runtimes like Wasmtime, Lucet, and Wasmer.

Unfortunately cosmopolitan wouldn't work for dockerc. Cosmopolitan works as long as you only use it but container runtimes require additional features. Also containers contain arbitrary executables so not sure how that would work either...

As for WASM, this is already possible using container2wasm[0] and wasmer[1]'s ability to generate static binaries.

I could not find any guide how to add WASM container capability to Docker running on Colima. This guide provides a few Colima templates for exactly this, which adds WasmEdge, Wasmtime and Wasmer runtime types.

Just suggested as well Wasmer on Twitter! https://github.com/wasmerio/wasmer

Looking forward to seeing the results :)

The Biome team has been incredibly fast on solving the challenge and achieving 95% compatibility with Prettier [1]

Just as a note, as it was not mentioned in the article, Wasmer [2] also participated with a $2,500 bounty to compile Biome to WASIX [3], and it has been awesome to see how their team has been working to achieve this as well... hopefully we'll get Biome running in Wasmer soon!

Keep up the great work!!

It's funny how WebAssembly can help overcome most of the issues mentioned on the blogpost (packaging, configuration, portability) if addressed properly.

That's the main reason Wasmer [1] was created :)

Thanks for the mention to Wasmer.

I'll put here a link in case is useful for future readers: https://wasmer.io/
