TinyHTTP

A minimal HTTP/1.1 server built from scratch in Go without using the net/http package.
The project demonstrates how HTTP works over raw TCP connections by manually handling request parsing and response generation.

Features

• TCP server using Go’s net package
• Manual HTTP request parsing
• Header handling with Content-Length support
• Structured request and response models
• Valid HTTP/1.1 response generation
• Method-based routing (GET /, GET /hello)

---

Architecture

TCP Connection → Request Parsing → Router → Handler → Response Writing

---

Project Structure

/cmd/server → entry point
/internal/http → request, response, parser, writer
/internal/server → connection handling
/internal/handler → router and handlers
/internal/transport → connection utilities

---

Run

go run cmd/server/main.go

Server runs on:

localhost:4221

Example

curl http://localhost:4221/

Response:

HTTP/1.1 200 OK
Content-Length: 11
Connection: close

Hello World
