How can I handle errors in Go template libraries?

In Go, you can handle errors in template libraries by checking for errors during execution. Use the Execute method and check its return value.

Can you give me an example of error handling in a Go template?

Sure! Here's a simple example:

err := tmpl.Execute(w, data)
if err != nil {
    log.Printf("Error executing template: %v", err)
}

What should I do if the template itself has syntax errors?

You can use the Parse method to check for syntax errors before executing the template. It will return an error if the template is invalid.

Is there a way to recover from errors during template execution?

Yes, you can implement error recovery by using a deferred function that handles panics, allowing your application to continue running.
