functional-ts-review

Railway-style error handling in TypeScript replaces thrown errors with pure state transitions using discriminated unions. Review checks ensure your code avoids unprotected thrown exceptions and uses exhaustive switch checks to safely route operations across success and failure paths.

Functional TypeScript code reviews should detect class usage, type assertions, thrown errors, and unprotected PII as anti-patterns. The review process provides actionable fixes to enforce boundary defense with schema validation and maintain consistent safety guarantees.

Enforce immutability and boundary defense in server-side TypeScript by validating schemas at system boundaries and avoiding type assertions. Code review passes surface compliance issues, ensuring exact file structure and pure functional domain modeling principles are maintained.

Yes, this functional TypeScript review specifically targets exhaustive switch checks and companion objects. It analyzes your codebase to ensure conformity with these structural patterns, providing actionable guidance to fix non-compliant domain modeling implementations.

Type assertions are considered an anti-pattern in functional TypeScript domain modeling and should be avoided in favor of schema validation for boundary defense. Code reviews detect type assertions and provide actionable fixes to ensure type safety without bypassing the compiler.
