http-server-rust

A from-scratch HTTP/1.1 server in Rust. No frameworks, no external HTTP libraries — just std and a couple of small crates.

Did this as part of the CodeCrafters HTTP Server challenge. Each commit is a new stage.

Features

• GET /echo/{str} — echoes back the string
• GET /user-agent — returns the User-Agent header
• GET /files/{filename} and POST /files/{filename} — read/write files from a directory passed via --directory
• gzip compression when the client sends Accept-Encoding: gzip
• Keep-alive connections — handles multiple requests on the same TCP connection
• Concurrent — each connection gets its own thread

How to run

cargo build --release
./target/release/codecrafters-http-server --directory /some/dir

Try it:

curl http://localhost:4221/echo/hello
curl -H "Accept-Encoding: gzip" http://localhost:4221/echo/hello | gunzip
curl -X POST -d "hello" http://localhost:4221/files/test.txt
curl http://localhost:4221/files/test.txt
