Building REST APIs with Go

March 5, 2025

Go’s standard library has everything you need for a solid REST API.

Minimal Server

package main

import (
  "encoding/json"
  "net/http"
)

func main() {
  http.HandleFunc("/api/health", func(w http.ResponseWriter, r *http.Request) {
    json.NewEncoder(w).Encode(map[string]string{"status": "ok"})
  })
  http.ListenAndServe(":8080", nil)
}

No framework needed for small services. The stdlib is surprisingly capable.
