Building a Simple REST API in Go (Without Frameworks)

Modern backend development often starts with a framework. But sometimes the best way to understand a language is to remove the abstractions. In this project, I built a minimal REST API in Go using only the standard library , without any external frameworks. The goal is simple: demonstrate how HTTP APIs work internally in Go. 👉 Project repository: go-native-api-sample Why Build an API Without Frameworks? Frameworks are powerful, but they can hide important concepts. When you build an API using only Go's native packages, you understand: how HTTP servers actually work how routing is handled how JSON serialization works how concurrency and shared state must be managed Go’s standard library is already powerful enough for many services. Project Structure The project is intentionally simple. go-native-api-sample ┣ main.go ┗ README.md All the logic is inside main.go , making it easy to explore how everything works. Starting the Server The server is created using Go’s net/http package. func mai
