Component Design Principles
- Keep Components Small: Breakdown UI into smaller components to enhance reusability and simplify maintenance. Smaller components promote focused functionality and easier testing.
- Use Cascading Parameters: Leverage cascading parameters for shared state among components, reducing redundant code and improving data flow. This enables components to inherit values from their parent components without complicated prop drilling.
- Separate Logic from UI: Implement the Model-View-ViewModel (MVVM) pattern to keep business logic independent from UI. This modular approach ensures cleaner code and bolsters overall application organization.
- Avoid Direct DOM Manipulations: Reliance on Blazor’s data binding simplifies updates and interactions. Avoid using JavaScript to manipulate the DOM directly to maintain Blazor’s architecture integrity.
- Implement Lazy Loading: Utilize lazy loading for components and data, optimizing initial load times and enhancing application responsiveness. Load only necessary resources to improve performance and user experience.
- Use Scoped Services: Implement scoped services with dependency injection for handling shared state within components. This approach ensures a single instance per user session, offering consistency throughout interactions.
- Implement Redux-like State Management: For applications with complex state requirements, consider using libraries that implement a Redux-like pattern. This centralizes state management and enhances predictability, easing debugging.
- Utilize Local Storage and Session Storage: Store critical application state in the browser’s local or session storage as needed. This strategy allows persistence across page refreshes while minimizing server calls.
- Handle State Changes with Events: Use event callbacks to communicate state changes between components. This facilitates decoupled interactions, improving maintainability and testability within the application.
- Keep State Immutable: Adopt immutable state patterns to control state changes predictably. Immutable state reduces chances of unintended side effects and simplifies debugging processes.
