Ryan's example (vimeo, youtube) reproduced in 2022. This repo just updates Ryan's example with latest API of http-parser and in llhttp. Maybe it is a good example to look at, before read other more complex http server projects based on libuv.

Simple. just make all. (Use llhttp: USE_LLHTTP=1 make all)

http-parser/llhttp-6.0.6 and libuv-1.44.1 libraries are statically linked.

./sample-server

In another terminal send a simple http get request with curl. (Run multiple times to connect to the server repeatedly)

curl https://localhost:8000/

sample output:

sample server launched
Waiting for connections...

on_connection

GET / HTTP/1.1

on close

Connect to the server and send random string to be displayed at the server side. Once the connection stops, event loop will also exit (uv_stop at main.cc:L130).

nc localhost 8000

There are many other implementations online and over the years some become more complex to support different platform and restructured to follow languages best practices. Here are a few others I found:
