Mastering TypeScript: Patterns for Large-Scale Apps
Production-tested TypeScript patterns and best practices for building maintainable, type-safe applications at scale.
TypeScript has become the standard for building large-scale applications. Here are the patterns we use at Agency to keep our codebases clean, type-safe, and maintainable.
Discriminated Unions
Discriminated unions are one of TypeScript's most powerful features. They enable exhaustive type checking and make impossible states impossible.
Generic Components
We build reusable components with proper generic constraints. This gives us type safety without sacrificing flexibility.
