stacks-error-handling

Type-safe error handling in TypeScript uses Result types with Ok and Err variants to capture predictable error flows. This approach standardizes error responses and structures logging across your application environments.

Standardizing error pages and logging is achieved through a configurable log system that maps HTTP errors and renders environment-specific pages. This framework separates development page rendering from production responses for consistent exception handling.

You convert Promises into Result types using the fromPromise utility, wrapping asynchronous operations in a type-safe Ok or Err object. This mechanism ensures predictable error flows without relying on try-catch blocks.

Yes, this error-handling framework applies to core framework development, APIs, and services. It provides centralized error logging and standardized exceptions like ModelNotFoundException for robust data access layers.

Use Result types when you need type-safe, predictable error flows across your stack instead of unpredictable thrown exceptions. This approach enables reliable error capture and structured logging for consistent application responses.

Mapping HTTP errors involves using the framework's error-page rendering and HTTP error mapping features to generate environment-specific responses. This standardizes how exceptions display during development versus production.
