Hey @Calvin Prewitt ! I'm working on adding support for pulling component dependencies via wasm-pkg-client to wasmCloud's CLI, and after talking with Taylor last week I heard there's some interest in a wkg.lock file. At the very least, an idea of a lockfile to maintain integrity/track digests/etc. I put a total strawman in https://github.com/wasmCloud/wasmCloud/pull/2879 which is mostly based off of deps.lock from wit-deps to start that conversation :smile:

Awesome stuff! Would be cool to chat about plans for it. What would your thoughts be about a .lock living in wasm-pkg-tools? We were also kindof thinking that there are some cool things about the wit tool in cargo-component that might be worth taking inspiration from.

Ooh yeah, https://github.com/bytecodealliance/cargo-component/blob/main/crates/wit/src/lock.rs looks like great inspiration. Yeah I think this .lock format should definitely live in wasm-pkg-tools

If you want you should come to the packaging meeting tomorrow. Or we could hop on a call somewhere else. Or chat here. But it would be cool to exchange some ideas about this. I've been doing a bad job of keeping up to date with Taylor's progress, but I think atm it still only interacts with warg?

I may attend the packaging meeting tomorrow :smile: Taylor's been rocking it, I was able to use this to pull all the wasi@0.2.0 deps via OCI from the released GitHub packages https://github.com/orgs/WebAssembly/packages?repo_name=WASI

So in the end after running through my PR I had the components and the lockfile:
