REST API Example: A complete RESTful API project in Go (RestAPI/)

REST API Project

The RestAPI/ folder contains a sample RESTful API built with Go. It demonstrates:

Project structure with cmd/, internal/, and config/ folders
Configuration management (config/local.yaml)
Database usage (storage/storage.db)
API endpoints for managing student data (cmd/student_api/main.go)

To run the REST API:

cd RestAPI
go run cmd/student_api/main.go -config config/local.yaml

Usage

To run any topic example, navigate to its folder and use:

go run main.go

Requirements

Go 1.18+
