Starting with a simple monolithic app or planning for a distributed system, code structure and organization will play a significant role in success.Consistent and logical folder structure is the backbone of a scalable React applicationIn a Feature-Based Structure, files are grouped by features or UI components.In a Domain-Based Structure, files are grouped by business domains rather than individual features. default exports for components and named exports for utilities and hooks to maintain clarity.For smaller or medium-sized projects, colocating test files alongside components keeps related files close together.Maintaining high code quality is crucial for scalability: tools like ESLint and Prettier can help.A good README.md file serves as a manual for your project, keep it updated and informative.In the next article, state management in React will be explored to dive deep into best practices for managing state in your React application.
