REST API in Go

What is this?

  • A REST API built in Go that allows the user to manage a set of courses

What can it do?

  • CRUD operations for managing courses
  • GET, POST, PUT, DELETE

How do you run it?

  • Install go @ https://go.dev/dl/
  • "go run *.go" - this starts the server on 8080
  • Use curl to hit the endpoints /courses, /courses/, /health

Project structure

  • main.go - main function with home handler
  • courses.go - Course struct and course handler functions
  • health.go - Health struct and health handler functions
  • Files grouped by domain

What you learned building it?

  • How APIs and JSON work. Reading request bodies and understanding how communication between the client and server works
  • How to extract IDs from the URL to handle specific requests
