middleware

func Logging ¶ added in v0.0.6

func Logging(name string, opts ...LoggingOption) minds.Middleware

Logging creates a middleware instance for structured logging.

func Retry ¶

func Retry(name string, opts ...retry.Option) minds.Middleware

Retry creates a middleware that provides automatic retry functionality for handlers.

The middleware offers configurable retry behavior, including:

• Customizable number of retry attempts
• Flexible backoff strategies
• Configurable retry criteria
• Optional timeout propagation

Default behavior:

• 3 retry attempts
• No delay between attempts
• Retries on any error
• Timeout propagation enabled

Example usage:

flow.Use(Retry("api-retry",
  retry.WithAttempts(5),
  retry.WithBackoff(retry.DefaultBackoff(time.Second)),
  retry.WithRetryCriteria(func(err error) bool {
    return errors.Is(err, io.ErrTemporary)
  }),
))

The middleware will stop retrying if:

• An attempt succeeds
• Maximum attempts are reached
• Retry criteria returns false
• Context is canceled (if timeout propagation is enabled)
