How can I manage context in a Go application?

How can I manage context in a Go application?

In Go, you can use the context package to manage deadlines, cancellation signals, and request-scoped values.

Can you give me an example of using context in a function?

Sure! Here's a simple example:

func fetchData(ctx context.Context) {
    select {
    case <-time.After(2 * time.Second):
        fmt.Println("Data fetched")
    case <-ctx.Done():
        fmt.Println("Request cancelled")
    }
}

What are the benefits of using context?

Using context helps in managing timeouts, cancellations, and passing request-scoped data, improving resource management.

Are there any common mistakes to avoid with context?

Yes, avoid using context for passing optional parameters or for blocking operations. It's meant for cancellation and deadlines.
