HTTP/2 support

[liclac]

Is this planned at all? And if I was interested in implementing it myself, where would I start?

[erikdubbelboer]

There is currently no plans to include HTTP/2 support into fasthttp. I myself would only like to add support if I was going to use http2 myself, otherwise it's too hard and time consuming to work on. Pull requests on either repo are always welcome of course.

Agree with both of you, Erik and Darío. Basically no HTTP/2 support is actively being built for fasthttp and no plans to support it in the future.

If any downstream project needs HTTP/2, it should not expect one from fasthttp. Instead it should implement HTTP/2 on its own, either by forking fasthttp and adding HTTP/2 support, or by building a separate extension to add HTTP/2.

[phuslu]

agree. I used to use fasthttp for rtb, and I realized we only need a http2 client rather than a http2 framework.

So I ripped a http2 implementation from grpc-go but haven't to verify it yet.

And... on top of that, who is going to use http/2 without GRPC support?

fasthttp is used by plenty of frameworks that aren't limited to computer-to-computer communication. Roughly 35-40% of the web properties use HTTP/2. You're using HTTP/2 fairly regularly without gRPC support.

That's not necessarily a reason for a fasthttp HTTP/2 implementation to be developed, but it definitely doesn't have to come with support for gRPC to be useful. JSON-over-HTTP works just as well for HTTP/2 and you'd still benefit from the improvements to the wire format like multiplexing and the HPACK header compression.

Websocket can handle that too.

@daenney Sure, I agree with you that it does have usages, but I don't even use Golang anymore (not only fasthttp but Go at all), so it doesn't make sense that I try to implement it because it would divert my focus from my current job. Also, I would not be able to test it in a daily basis because I wouldn't be using it, therefore I would have to wait for people to report bugs, etc... I don't wanna sell a product that I wouldn't even buy.

PLEASE MENTION IT IN THE README! that this lib doesn't support http2

@apuatcfbd you mean like this snippet that already exists in the README: https://github.com/valyala/fasthttp/blob/5f81476d7cf339624b5fec57a06ee96d3e27d9c2/README.md?plain=1#L577-L581
