Description

RE: https://github.com/ipfs/kubo/blob/master/docs/experimental-features.md#plugins

Wazero is 100% golang and can run wasm on anything. even mobile.

Making plugins that are compiled to wasm is pretty easy these days, as well as how they are exposed.

for a P2P system it also means that you don't need to trust the plugins because they are sandboxed.

lots of wazero frameworks out there too: https://github.com/tetratelabs/wazero/blob/main/site/content/community/users.md?plain=1

The best one that i use is https://docs.timecraft.dev

• code: https://github.com/stealthrocket/timecraft

• can be bound to file systme or network with decent control.

@gedw99 we are not intrested in wasm for the sake of having wasm.

We would review each plugin usecase one by one. What would like to do with a wasm plugin ?

[Jorropo]

Note about https://github.com/ipfs/kubo/blob/master/docs/experimental-features.md#plugins, this can't work for wasm plugins, this is using golang's builtin plugin system, this is not cross ABI compatible, you can't load a wasm plugin into an amd64 binary, this isn't easily 1 to 1 mappable since our code internally relies on reflection and type assertions.

We don't have the resource to enginer a complex solution that would modify go's runtime to permit to do that.

Thus that why if usecases needs to be viewed one by one.

P2p computing where you bring the compute to the data .

[Jorropo]

That is different from plugins and require widely different technical works: trusted vs untrusted code, state and lifecycle are completely different.

Here we are looking for API and technical designs of what we would implement.

P2p computing where you bring the compute to the data .

@gedw99 building off of @Jorropo's comments above you can already build a number of different plugins using these interfaces https://github.com/ipfs/kubo/blob/master/docs/plugins.md#plugin-types and have the plugin use a WASM runtime and dynamically load and execute code for you if you'd like. So if you're looking for something more that would mean describing something specific in order to match.

My issue is specific & actionable.

For example:

• Maybe you wanted an IPLD plugin type like [Experiment] WASM IPLD Codecs and ADLs #9016, which means that the issue is defining an IPLD codec and/or ADL ABI
• Maybe you want a way to hook up custom CLI commands in Go so you can leverage IPVM (https://github.com/ipvm-wg/) or some other tool to execute WASM for a defined ABI (although presumably you could also just leverage stock kubo or build a boxo-based binary to do something similar)
• ...

Which is why

Here we are looking for API and technical designs of what we would implement.

If you're looking for more general community feedback on what using kubo + WASM together might look like https://discuss.ipfs.tech/ or some of the community chat channels are probably better places to start.
