React Patterns

A solid reference guide that covers the essentials without drowning you in theory. It walks through component design principles, hook patterns, state management decisions, and React 19's new hooks like useActionState and useOptimistic. The tables are actually useful for quick lookups on when to extract custom hooks or which state solution fits your complexity level. It includes a practical anti-patterns section that calls out common mistakes like prop drilling and premature optimization. The file structure diagram gives you a concrete starting point for organizing larger apps. Best used when you're setting up a new React project or need to justify architectural decisions to your team.
