Martini Video Tutorials - Error Handling in Services

Error handling is a critical aspect of developing robust services in Martini. It allows developers to manage exceptions and ensure that the service can handle unexpected situations gracefully. This section provides an overview of error handling techniques available in basic services, helping you to implement effective error management strategies.

Topics Covered

  1. Basics of Error Handling: Understand the fundamental principles of error handling in Martini services. This section covers the types of errors you may encounter and the importance of implementing a structured error-handling approach.

  2. Logging to Console: Learn how to log errors to the console, providing immediate feedback during development and debugging. This method helps in tracking errors as they occur, facilitating quick identification and resolution.

  3. Logging to Service: Explore the process of logging errors to an external service. This approach allows you to centralize error reporting, making it easier to analyze and manage errors over time. It also supports integration with monitoring tools for enhanced visibility.

  4. Handling Errors: Discover best practices for handling errors within your services. This section discusses strategies for anticipating errors, using appropriate error types, and implementing recovery mechanisms to maintain service stability.

  5. Custom Exceptions: Learn how to create and manage custom exceptions to represent specific error conditions in your applications. Custom exceptions allow for clearer error reporting and more targeted error handling:

    • Using Validate Expression: Understand how to use the Validate Expression feature to check conditions and throw custom exceptions when validation fails. This ensures that only valid data is processed, reducing the likelihood of runtime errors.
    • Explicitly in a Service: Explore methods for explicitly throwing custom exceptions within your service logic. This section covers scenarios where throwing exceptions is necessary to control workflow execution and communicate issues effectively.
    • Creating Exception Class: Learn how to create your own exception classes in Martini, enabling you to define specific error types that can be caught and handled appropriately in your workflows. This promotes better organization and clarity in error management.
