adonisjs-exceptions

Domain error handling in AdonisJS is managed by creating self-contained exceptions with static factories. Each exception implements handle() to return structured HTTP responses and report() for logging, ensuring consistent status codes and messages across service layers.

Standardizing exception messages in AdonisJS is achieved by extending a base Exception class with static factory methods. This pattern encapsulates descriptive, contextual errors and reusable response behaviors directly within the exception definitions stored in app/exceptions/.

To create custom exceptions in AdonisJS, extend the base Exception class and add static factory methods for each specific failure scenario. Implement handle() to define per-error HTTP responses and report() for structured logging of invalid states.

Yes, self-contained exceptions are designed for AdonisJS service and action layers where business rules and invalid states must throw rich, structured errors. They provide static factories to generate contextual domain errors with consistent codes and messages.

AdonisJS exception handling supports per-exception logging through the report() method. This structured reporting mechanism ensures that domain errors are logged consistently while handle() separately manages the HTTP response output.

Static factory methods for AdonisJS exceptions provide descriptive, contextual errors for specific failure scenarios. They standardize error creation by encapsulating business rules, ensuring consistent messages and reusable patterns across services and controllers.
