Could this server accept http2?

[Rainton]

It looks like http2 is not supported, do you have any plan to add this feature?

No plans but that would be nice, maybe even include HTTP3 if it's simple. But I'm not seeing a straightforward solution.

It looks like Express doesn't support HTTP2 : expressjs/compression#122 and there's an ongoing/stalled pull request for its implementation: expressjs/express#3730

I see some mentions of 'spdy', but that is not compatible with Node 16: spdy-http2/node-spdy#380
