Servy

A minimal HTTP server built with pure Elixir and the Erlang runtime.

This project is designed to refresh core fundamentals of Elixir, including:

• processes and concurrency (BEAM model)
• pattern matching
• recursion
• raw TCP sockets via :gen_tcp

No frameworks, no abstractions

---

Running the Server

Start an interactive shell:

iex -S mix

Then run:

Servy.start(4000)

You should see:

Listening on http://localhost:4000

---

Try it out

In another terminal:

curl http://localhost:4000/
curl http://localhost:4000/health

What this project demonstrates

• Handling HTTP over raw TCP
• Spawning a process per request
• Parsing request lines manually
• Building HTTP responses from scratch
