15 tips for better Angular component architecture

I'm excited to share some invaluable tips on enhancing your Angular component architecture! These insights are designed to help you build robust, scalable, and maintainable applications. If you find these tips useful, check out my course, "Build Huge Angular Applications," for a deeper dive into these concepts and more. I'll also be posting a lot of free content on my blog. Let's dive in!

1. Prefix Your Selectors

Always prefix your component and directive selectors. For instance, if your project name is Simplified Courses, use a prefix like sc-. This practice helps distinguish your code from third-party libraries and avoids naming conflicts.

2. Use Kebab-Case for Component Selectors

Adopt kebab-case for component selectors to align with HTML standards. This makes it easier to differentiate between components and directives, ensuring consistency and readability in your code.

3. Create Small Components

Break down large components into smaller, manageable pieces. Small components are easier to maintain, test, and reuse. They promote separation of concerns, making your codebase cleaner and more modular.

4. Separate Components for Specific Responsibilities

Create separate components for forms, modals, and reusable logic. This practice enhances the clarity of each component’s responsibility, making your application more organized and easier to maintain.

5. Optimize Performance with OnPush

Use the OnPush change detection strategy to optimize component performance. OnPush reduces the frequency of change detection cycles, improving the efficiency of your application, especially in large-scale projects.

6. Use Content Projection for Consistent Layouts

Leverage content projection in layout components to enforce consistent layouts across your application. This approach reduces redundancy and ensures a uniform look and feel throughout your app.

7. Use Attribute Selectors for Extending Elements

Attribute selectors are perfect for extending existing elements like buttons and inputs. This allows you to enhance native elements without wrapping them in new components, preserving their original behavior.

8. Utilize Element Selectors for Custom DOM Tags

Element selectors are ideal for creating custom DOM tags and layout components. They help in creating new, reusable HTML elements that fit seamlessly into your application.

9. Narrow Down Your Selectors

Ensure your selectors are as narrow as possible to avoid misuse. For instance, using table[sc-table] ensures the selector only applies to table elements, maintaining the integrity of your component's functionality.

10. Differentiate Smart and UI Components

Clearly distinguish between smart and UI components. Smart components manage application logic and state, while UI components focus on presentation. This separation simplifies your architecture and promotes reusability.

11. Maintain Unidirectional Data Flow

Ensure unidirectional data flow by using inputs for data to flow down and outputs for events to flow up. This makes your application easier to debug and maintain.

12. Use Routed Components for Better Navigation

Routed components, such as pages, dialogs, wizards, and tabs, enhance user experience by being bookmarkable, refreshable, and shareable. They leverage native browser navigation for a more intuitive UX.

13. Avoid Injecting Parent Components into Children

Avoid injecting parent components into child components to prevent tight coupling. This practice leads to a more modular and maintainable codebase.

14. Use Injectables with Signals for State Management

Use injectables with signals to share state between parent and child components. This approach takes advantage of Angular's powerful dependency injection system for efficient state management.

15. Treat Components as State Machines

Treat your components as state machines with well-defined initial states. This makes them predictable and easier to manage, especially when dealing with complex interactions and data flows.

I hope you find these tips helpful in improving your Angular component architecture. If you're eager to learn more, consider enrolling in my course for an in-depth exploration of these topics and more.
