#componentmodel — Public Fediverse posts

I wonder why we do not have a repository for wasm components and their wit based descriptions, like we have mvnrepository etc for the jvm world. Does anyone know of such an effort?

wkg already allows to upload in an OCI compatible style. What would be required now, is to make this searchable.

When I use cargo component new to build a CLI component for Rust/Wasm/Wit, the cargo component build step will automatically translate a main function to .e.g. wasi:cli/run or println! statements to the according stream functions from the wasi world. With wasm-tools component wit I can even inspect a generated with world, though none was supplied. I would llike to know more about the magic involved. Is that documented somewhere, is this something carfgo component does, or is it coming from wit-bindgen? Any help or pointers appreciated.

As a complete aside: over the last few months, I've put together a little workbench repo to get myself conversant with the Wasm component model.

https://github.com/dylibso/component-workbench

It consists of a series of ".wat" files, some of which include an associated runner. Each file attempts to isolate one bit of syntax, building up to late-bound host functions.

These files are intended for people to read and edit – change stuff and see what happens!

# Microsoft exploring .NET + Wasm/WASI

Richard Lander from Microsoft wrote a blog post on the future of Wasm + WASI with .NET in the cloud.

Also, Steve Sanderson from Microsoft created an Experimental SDK for using WASI/WIT in .NET.

so, a few #wasm #componentmodel questions as I’ve started digging into this:

1. As a provider of host functions that are intended to “mix into” other worlds, should I prefer to export interfaces that can be imported separately or a world that can included wholesale?

2. re cargo-component: what is the difference between “package.metadata.component.dependencies” and “package.metadata.component. target.dependencies”?
