What are async APIs in Go and how do I implement them?

Async APIs in Go allow for non-blocking operations, enabling better performance in concurrent applications. You can implement them using goroutines and channels.

Can you give me a simple example of an async API in Go?

Sure! Here's a basic example:

package main

import (
    "fmt"
    "time"
)

func asyncFunction() {
    time.Sleep(2 * time.Second)
    fmt.Println("Async function completed")
}

func main() {
    go asyncFunction() // Call async function
    fmt.Println("Main function continues...")
    time.Sleep(3 * time.Second) // Wait for async function to finish
}

This code demonstrates how to run a function asynchronously.

What are the benefits of using async APIs?

The benefits include improved performance, better resource utilization, and the ability to handle multiple tasks concurrently without blocking the main thread.

Are there any libraries in Go that help with async programming?

Yes, libraries like goroutines, channels, and frameworks like Gin or Echo can help manage async operations effectively.
