Angular's robust features and structure make it a favorite for building dynamic web applications. However, mastering the intricacies goes beyond components, directives, and dependency injection.
Let us see the top ten less-common tips to improve your Angular development game.
Use Smart Components and Container Components
Traditionally, components handle both UI and logic. You can consider separating them! Smart components manage data and logic, while container components handle presentation and user interaction. This separation improves maintainability and reusability.
RxJS for the Win: Use Observables
Angular uses RxJS, a powerful library for asynchronous programming. Move beyond simple promises and leverage Observables for complex data streams. Operators like map, filter, and combineLatest allow for elegant data manipulation, leading to cleaner and more reactive applications.
Lazy Loading for Optimal Performance
Large Angular applications can feel sluggish. You can implement lazy loading to load features on demand. It reduces initial load time and improves perceived performance, especially for users with slower connections.
Style Guide Enforcement: Maintain Consistency
A consistent codebase is easier to maintain and understand. Use tools like ESLint and Stylelint to enforce a style guide. These tools identify stylistic inconsistencies and enforce coding conventions, leading to a cleaner and more uniform codebase.
Testing Beyond Components: Use End-to-End Testing
Unit testing is crucial, but don't neglect end-to-end (E2E) testing. Tools like Protractor or Cypress simulate user interactions and validate overall application behavior, ensuring a seamless user experience across different scenarios.

Use Dependency Injection for Loose Coupling
While dependency injection (DI) is a core Angular concept, take it a step further. Inject interfaces instead of concrete implementations. This promotes loose coupling, making your components more flexible and accessible to test in isolation.
Server-Side Rendering (SSR) for SEO Boost
Many Angular applications are single-page (SPAs), which can be less SEO-friendly. Explore server-side rendering (SSR) to improve search engine optimization by generating static HTML on the server.
Ahead-of-Time (AOT) Compilation
AOT compilation translates your TypeScript code into efficient JavaScript during build time. This improves application performance and reduces runtime overhead, especially for larger applications.
Progressive Web Apps (PWAs): Go Beyond the Web
PWAs combine the best of web and native apps. By leveraging features like service workers and push notifications, you can create an engaging user experience that feels app-like, even without an internet connection.
Bonus Tip 1: Utilize Custom Decorators for Code Reusability
Angular decorators are functions that modify classes or properties. Create custom decorators to encapsulate common logic or patterns. This promotes code reuse and reduces boilerplate code, making your components cleaner and easier to understand.
Bonus Tip 2: Implement Universal Schematics for Faster Development
The Angular CLI offers schematics for generating components, services, and other common elements. Take it a step further and create custom schematics for frequently used functionalities within your application. This streamlines development and reduces the time spent on repetitive tasks.
Stay Updated: The Angular Ecosystem Evolves
The Angular ecosystem is constantly evolving. Keep yourself updated with the latest features, libraries, and best practices. Utilize resources like the official Angular blog and community forums to stay ahead.
By incorporating these less common tips, you can elevate your Angular development skills, build cleaner, more performant, scalable web applications, and impress your fellow developers!
