Building High-Performance APIs with Go

Why Go for APIs?

Go (Golang) is known for its simplicity, performance, and excellent concurrency support, making it ideal for building high-performance APIs.

Basic HTTP Server

package main

import (
    "encoding/json"
    "net/http"
    "github.com/gorilla/mux"
)

func main() {
    router := mux.NewRouter()
    router.HandleFunc("/api/users", getUsers).Methods("GET")
    router.HandleFunc("/api/users", createUser).Methods("POST")
    http.ListenAndServe(":8000", router)
}

func getUsers(w http.ResponseWriter, r *http.Request) {
    w.Header().Set("Content-Type", "application/json")
    json.NewEncoder(w).Encode(users)
}

Go Advantages

• Fast compilation and execution
• Excellent goroutine support
• Clean and readable code
