Bun.serve TCP SYN FLOOD

[ornate crater]

That's not how tcp works

tcp handshake is a c->s syn, s->c syn+ack, and c->s ack

http(s) traffic only happens after that handshake

there's no such thing as a "tcp http packet"

http data are transmitted through regular tcp packets

for ddos prevention, try cloudflare

If the server is actually crashing, that is a problem

It shouldn't be possible to crash the server with any amount of traffic

[ornate crater]

it depends on the crash

if it's an out of resource issue, there's not too much bun can do except allow setting limits on connections (which it might already have, check the docs)

but a syn flood thing should be getting handled at the os level (which bun won't know about at all)

[ancient marten]

yeah that's what i was thinking too, bun doesn't implement TCP itself, it just uses your OS' underlying socket implementation

have you tried setting a timeout on your connections for your http server? that could help prevent crashes
