strict-typescript-mode

To enforce strict TypeScript type safety and prevent implicit any usage, enable strict compiler options like noImplicitAny and strictNullChecks in tsconfig.json, and add lint rules to require explicit return types on public APIs.

Migrating a JavaScript project to TypeScript safely requires enabling strict compiler flags, forbidding bare any usages without documented justification, and using type guards with runtime checks to prevent accidental type leakage during the conversion.

Configuring TypeScript lint rules to disallow any involves adding eslint rules that forbid bare any usages in new code unless explicitly justified, and enforcing explicit types on exports to improve overall code readability and maintainability.

Use generics with constraints and TypeScript utility types during refactoring to create safer abstractions, ensuring that flexible components maintain strict type checking without relying on implicit any or losing type safety.

Strict TypeScript mode works with TSX projects during feature work by validating code changes through the TypeScript compiler and linting tools, enforcing explicit API types, and preventing accidental type leakage in component implementations.
