TypeScript Best Practices

Enable strict mode for new projects

Use interface over type for object shapes (generally)

Leverage type inference instead of explicit typing everywhere

Implement discriminated unions for complex state

Use const assertions for literal types

Create utility types for common patterns

Set up path aliases for cleaner imports

Use branded types for domain primitives

Scaling Considerations

TypeScript becomes more valuable as codebases grow. Consider project references for large monorepos to optimize build times.

Security Considerations

Type safety helps prevent runtime errors but doesn't replace runtime validation. Use Zod or similar for runtime type checking at system boundaries.

Performance Optimization

TypeScript compiles to JavaScript with no runtime overhead. Use incremental compilation, project references, and proper tsconfig for faster builds.

Success Story
