A Go library providing tools and strategies for centralized error handling, logging, and integration with error monitoring services.
Emperror is a Go library that provides tools and strategies for centralized error handling, making it easier to record, log, and integrate errors with monitoring services. It addresses the challenge of handling errors when recovery isn't possible by ensuring errors are captured with full context at the highest level of the application stack.
Go developers building applications that require robust error handling, logging, and integration with error monitoring services like Sentry or Bugsnag.
Developers choose Emperror for its simple interface, extensive integrations with popular error catchers, and utilities like panic recovery and error filtering, which streamline error management in Go applications.
The Emperor takes care of all errors personally

Provides a simple interface for various error handling strategies, such as logging and third-party services, as stated in the README's 'Features' section, making it easy to adopt consistent error management.
Includes helpers like HandleRecover and Panic to recover from panics and handle them as errors, demonstrated in the 'Panics and recovers' code example, enhancing application robustness.
Offers built-in integrations with popular error catchers like Sentry, Bugsnag, and Airbrake, listed in the README, simplifying monitoring setup for production environments.
Allows filtering of errors to prevent certain types from being handled, useful in server contexts as shown in the 'Filter errors' usage example, providing flexibility in error handling logic.
Only provides direct integrations with Logur and Logrus, missing native support for other popular Go logging libraries like zap or zerolog, which may require additional adaptation effort.
Setting up integrations with third-party services requires additional configuration and dependencies, as hinted by the separate handler packages, adding complexity compared to simpler error handling approaches.
Tight integration with specific error catchers can lead to vendor lock-in, making it harder to switch services if project requirements change, as the framework is built around these integrations.
