Minimal REST API with GO

Building a Minimal REST API in Go: Overview of the mini-rest-api Repository

The mini-rest-api repository (https://github.com/gokayburuc/mini-rest-api) hosts a compact implementation of a RESTful web service written in Go. The project showcases practical backend fundamentals using the Go standard library along with the popular routing package gorilla/mux. (GitHub)

Project Purpose and Scope

The repository aims to demonstrate how to construct a simple REST API with essential components such as routing, middleware, and CRUD endpoints. It functions as a Todo-style application, managing in-memory tasks rather than persisting data to an external database. The design emphasizes clarity and straightforward backend structure rather than production readiness. (GitHub)

Key Features

• Go HTTP Server Setup The application uses Go’s net/http package as the foundation for serving HTTP requests. (GitHub)

• Routing with Gorilla Mux The gorilla/mux router enables expressive route definitions, handling endpoint registration for operations such as creating, listing, and retrieving todo items. (GitHub)

• RESTful Endpoints API routes support typical REST methods:

  • GET /todos to list all tasks
  • POST /todos to create a new task
  • GET /todos/{id} to fetch a specific task by identifier (GitHub)

• Middleware Integration Middleware is included in the structure to illustrate request logging or other cross-cutting concerns, aligning with standard server architecture practices. (GitHub)

Architecture and Organization

The repository follows a clean package layout:

• cmd/server contains the entry point for the server application.
• internal holds modular packages such as handlers, models, routes, and middleware.
• Dependencies are tracked via Go modules (go.mod and go.sum). (GitHub)

Running the Application

To run the API locally, install Go (version 1.20 or later) and execute:

go run cmd/server/main.go

The server defaults to listening on localhost:8080, exposing the defined REST endpoints. (GitHub)

Limitations and Future Work

The implementation uses in-memory storage, which means data is not persisted across restarts. The repository notes potential improvements, such as adding update and delete endpoints, unit tests, and containerization via Docker. (GitHub)

Conclusion

The mini-rest-api project is a compact, instructional example of building a REST API in Go. Its clear structure and minimal dependencies make it suitable for developers seeking a lightweight template to study or extend for more complex backend services. (GitHub)
