wasm-ext: Replace libp2p-wasm-ext with libp2p-websocket-websys

[thomaseizinger]

@vincev built a pure Rust websys-based websocket transport here: https://github.com/vincev/libp2p-websys-transport

We currently offer something similar in https://github.com/libp2p/rust-libp2p/tree/master/transports/wasm-ext but involves Javascript.

The libp2p-wasm-ext transport is a bit more capable because it allows arbitrary transports to be plugged in. In reality, you can only use websocket though. Both WebRTC and WebTransport are not possible because they have a built-in security protocol and multiplexer.

@mxinden Should we retire our libp2p-wasm-ext module in favor of one with websys bindings?

[dariusc93]

Honestly, I dont see a downside to migrating over to websys since it would be less code (eg js) to maintain.

[mxinden]

I don't have much experience with either. Off the top of my head this sounds like the right step forward.

[thomaseizinger]

@vincev Would you be up for contributing your transport to the mono repo?

[vincev]

@thomaseizinger sure no problem, how can I help?

[thomaseizinger]

Really, all there is to do is deleting the existing libp2p-wasm-ext from this repository and moving your crate into the workspace! We'd also need you do add the @libp2p/rust-libp2p-maintainers teams as owners to the crate on crates.io so we can publish updates going forward.

If that works for you, it'd be great if you could send a PR!

[vincev]

Sounds good, I'll create a PR in the next few days.

[vincev]

How do I add you as owners? I tried the following but I am getting an error:

cargo owner -v --list libp2p
    Updating crates.io index
tomaka (Pierre Krieger)
mxinden (Max Inden)
github:paritytech:core-devs (Core devs)
github:paritytech:libp2p-devs (Libp2p devs)
github:libp2p:repos-rust (Repos - Rust)
github:libp2p:rust-libp2p-maintainers (rust-libp2p Maintainers)

and then when I try to add maintainers I get:

cargo owner --add github:libp2p:rust-libp2p-maintainers
    Updating crates.io index
error: failed to invite owners to crate `libp2p-websys-transport` on registry at https://crates.io

Caused by:
  the remote server responded with an error: could not find the github team libp2p/rust-libp2p-maintainers

[thomaseizinger]

I am not sure about the exact syntax. @mxinden Can you help?

[mxinden]

Not sure whether this is still an issue.

cargo owner --add github:libp2p:rust-libp2p-maintainers
    Updating crates.io index

My first guess would be that you can only add a GitHub group in case you are part of that group. Would that make sense?

Yes makes sense, but you are right we don't need to do this anymore as you now own libp2p-websys-websocket.
