result-type-error-handling

The Result type pattern in TypeScript models failures as explicit return values instead of throwing exceptions, allowing you to represent and propagate errors type-safely across your application.

You distinguish domain errors from technical failures in TypeScript by using the Result type to enforce explicit conversions, ensuring business rule violations and infrastructure faults are handled separately.

To replace exceptions with Result flows in TypeScript, catch exceptions at infrastructure boundaries and convert them into Result values, then propagate those Results through your domain and application layers.

Use Result types instead of exceptions when handling recoverable domain errors and business rule validations, ensuring explicit error propagation across application services and infrastructure interactions.

Railway-oriented programming in TypeScript structures error propagation so that successful operations flow sequentially while failures short-circuit, achieved by chaining Result type values across architectural layers.

Yes, you can use Result types to handle errors across layers in TypeScript by enforcing conversions between domain errors and technical errors, providing clear propagation patterns from infrastructure to domain.
