Wasm/web support? #1388

Closed FredrikNoren closed 2 years ago

FredrikNoren commented 2 years ago

Hey guys,

Do you have any plans to support wasm as a target for quinn? (On the web I mean, i.e. being able to compile a project with quinn and then running it on a website).

Ralith commented 2 years ago

For very good security reasons, webpages cannot send/receive arbitrary UDP packets, so it is impossible to run a QUIC implementation inside one. You might be interested in WebTransport an upcoming web standard that will allow similar capabilities.

@Ralith Ok, thank you!

@Ralith Would this also apply for a rust / quinn client in wasm32-unknown-unknown? Where can i find more info on this?

Thanks.

Ralith commented 1 year ago

I don't think wasm32-unknown-unknown defines any socket APIs at all, so that will depend on what nonstandard APIs your specific runtime environment provides.

Hi, just so I understand:

quinn is an implementation of the QUIC protocol, but cannot be used in the browser?
we need the WebTransport standard to be finalized to have browsers be able to talk to clients via QUIC protocol. It's implemented by Chrome/Chromium, but not by other browsers.

See https://github.com/quinn-rs/quinn/issues/1388#issuecomment-1199750713.

Just for completeness, would quinn support webtransport once it's released, or is that explicitly not a planned feature/target?

For context am building a project in bevy using quinn and evaluating what it would take to support WASM :) cheers

There are now implementations of WebTransport that use Quinn, e.g. https://github.com/kixelated/webtransport-rs. Quinn is a QUIC implementation, and WebTransport is built on top of (HTTP/3 which is built on top of) QUIC.
