TypeScript Best Practices for React and Node.js

TypeScript enables safer systems and more predictable maintenance across frontend and backend codebases.

Best practices

• Prefer explicit typed function signatures and generics.
• Use unknown instead of any for external API responses.
• Build reusable utility types for domain models.
• Keep strict compiler settings enabled to catch issues early.

Developer experience

Strong typing should support refactors, provide autocompletion, and prevent runtime errors without slowing engineering progress.
