Learn how to structure your projects and organize code for better maintainability, scalability, and collaboration.
As projects grow in size and complexity, a well-thought-out structure becomes essential. A good project structure makes it easier for developers (including your future self) to find files, understand the application's architecture, and add new features without breaking existing ones. There are several common patterns. A 'type-based' structure groups files by their type (e.g., all components in a `components` folder, all services in a `services` folder). A 'feature-based' structure groups files related to a single feature together (e.g., everything related to 'user-profile'—component, styles, tests—goes into a `user-profile` folder). The feature-based approach is often preferred for larger applications as it improves modularity. Beyond folder structure, good code organization relies on principles like DRY (Don't Repeat Yourself) and creating small, single-responsibility functions and components. Adopting a consistent style guide and using tools like ESLint (a linter to catch errors and style issues) and Prettier (an automatic code formatter) are crucial for maintaining code quality and consistency across a team.
