Handling Errors in Go: A Simple Example

Effective error handling is crucial for building robust Go applications. Here’s a straightforward example of error handling in Go:

Code Example

package main

import (
    "fmt"
    "log"
)

func processRequest() error {
    // Simulate an error
    return fmt.Errorf("simulated error")
}

func main() {
    if err := processRequest(); err != nil {
        log.Printf("Error processing request: %v", err)
        fmt.Println("Internal Server Error")
        return
    }
    fmt.Println("Request processed successfully!")
}

Running the Code

To run this code:

1. Copy the code into a .go file, e.g., main.go.
2. Use the following command to execute it:

   go run main.go

1. You will see the output based on whether the simulated error is processed or not.
