Building Scalable React Applications: Best Practices

State management deserves careful consideration—while Context API works for simple cases, larger applications often benefit from libraries like Redux or Zustand. The key is to choose the simplest solution that meets your current needs while allowing for future growth.Performance optimization becomes critical at scale, requiring techniques like code splitting, memoization, and virtualization for large lists. TypeScript integration catches errors early and makes refactoring safer as your codebase evolves.Testing should cover units, integration, and end-to-end scenarios to prevent regressions. Documentation and consistent coding standards enable teams to collaborate effectively as the application grows in size and complexity.
