TypeScript Best Practices for Large-Scale React Applications

TypeScript brings invaluable type safety to React development, but without thoughtful conventions, large codebases can become difficult to navigate. This article presents the patterns we use across our projects.

We cover type inference strategies, generic component patterns, discriminated unions for state management, and utility types that reduce boilerplate while improving safety.

The guide also addresses common pitfalls like over-typing, any-creep, and the balance between strict and practical type definitions in a team environment.
