G’day, if anyone has any questions about this I’m happy to answer them here.

Thanks! If you’ve got a way to add node packages to your frontend then it is pretty straightforward. If not, using unpkg ( https://unpkg.com/ ) in a script tag should work. Happy to help you figure it out! Post in the discuss

I have a project that does this: https://runno.dev No shared state between elements, but it’s an interesting idea. Edit: It runs other languages as well, like Python, C, Ruby.

This is just plain wrong. Web Components work in every browser that matters. They are standard DOM elements and can be written in plain HTML server-side or via legacy front-end libraries. I'm using web components in production to help

I think framing it this way can lead to real gripes with the interface. Web Components are a great way to build individual components that can be reused across an app, website, or shared as part of a library. They are like helper function

I’ve been using lit in side projects (e.g. runno.dev) and really enjoyed it. Just like any framework it can be a bit confusing learning the primitives but I’ve found it as productive as React, Vue or Svelte. The thing I like most about lit

Big fan of the sizzle. Its nice to get a real persons quick short take of the tech news, rather than having to read every long winded press release rewritten as news - or worse - drinking from the firehose on twitter.

I don't really know much about the component model, sorry!

Good idea! It's a bit harder, but totally doable.

Oh awesome!! I've just added Trealla to my issues list to add it to Runno. If you go into settings you can switch stdin echo on/off. I have stdio devices set up to return their file type as "Character Device" (see: http

It’s really cool stuff, hey! Early days but really interesting applications in serverless so far.

Good spotto! That's an old WASI runtime from wasmerjs ( https://github.com/wasmerio/wasmer-js ). That's not the WASI runtime being used in this playground. The one in this playground is @runno/wasi-motor (

I've also put up an article with a walkthrough of how to use the playground to run FFmpeg: https://runno.dev/articles/ffmpeg

Yeah the documentation is rather lacking and hard to understand. The best place to start is here: https://wasi.dev/

Yeah absolutely. Webassembly.sh was a big inspiration for my original build for Runno ( https://runno.dev ). The `prompt` issue is caused by code-rot, it used to work but then stopped working after browsers standardised a workarou

memfs is very cool, but the WASI runner in this demo doesn't use it. I implemented my own virtual filesystem (see: https://github.com/taybenlor/runno/blob/main/packages/wasi-m... ). Will look at

by benno128 4y ago
Thanks! What's super neat here is that I didn't have to build that. The WASI standard defines `fd_fdstat_get` which tells the binary the type of the file descriptor. For stdin/stdout/stderr I return that it is a "Ch

G'day! It's a bit hard to understand what this is, because there's a lot of other stuff in the space. What I've written here is a WASI runner for the browser. I've also hooked up a terminal and virtual FS to it. WAS

I built a WASI playground and you can run FFmpeg in it, which is cool(runno.dev)

There are some vegans and vegetarians who subscribe to a "no pain" version of this which allows eating creatures like oysters who verifiably can't feel pain.

It's part of the Atomics feature set ( https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... ). You have a shared chunk of memory and you say "please sleep until this memory changes&quo

There's a version of CPython 3.6 compiled here ( https://wapm.io/package/python ) which is ~5mb gzipped.

In WebAssembly.sh ( https://github.com/wasmerio/webassembly.sh ) they run WASM binaries in a Web Worker and then use `SharedArrayBuffer` to block the WebWorker while the main thread does some work (e.g. collect input). Y

I'm not super familiar with webassembly.studio but it does look like you could use runno to implement something like that. You'd want to look at the Host API to start with if you wanted to build a proof of concept.

Thanks Syrus! The stuff you're all building at Wasmer has been really useful (and is super cool).

by benno128 5y ago
Yeah I love the use case of documentation! Right now Runno wouldn't be great for libraries (or web requests!) but it's definitely something I'd like to support. I guess it would depend on the browser. There's two differe

G'day! A year or so ago I was playing around with building an online Introduction to Python course, but I got distracted by this problem that seemed like it should be solved: how can I embed runnable snippets on the web? There’s a bunc
