Best Practices for Writing Clean and Efficient Code in Angular!

🌟 Shalin started working with Angular in 2015, it’s been 9 years today working on all versions from Angularjs to Angular 17. We’ve learned that following best practices can make a significant difference in the quality, maintainability, and performance of our code. 🌟

Angular 18 has arrived.

Some learnings we at Ncoresoft Technologies would like to share:
1. **Follow a Modular Architecture** 🏗️
– Break your application into feature modules. This enhances maintainability, improves load times with lazy loading, and keeps your codebase organized.

2. **Leverage Angular’s Dependency Injection** 💉
– Use Angular’s built-in dependency injection for managing services. This promotes loose coupling and enhances testability.

3. **Utilize Reactive Programming** 🌐
– Use RxJS to handle asynchronous operations. Reactive programming makes your code more predictable and easier to manage. In some cases, we use template driven approach too but majorly I follow Reactive forms.

4. **Strictly Type Your Code** 🔒
– Take full advantage of TypeScript’s type system. Explicit types help catch errors early and make your code more understandable.

5. **Implement State Management** 🗃️
– For complex applications, consider using state management libraries like Reducers in NgRx . This helps manage application state predictably and efficiently.

6. **Optimize Change Detection** 🔄
– Use `OnPush` change detection strategy when possible to improve performance. This reduces the number of checks Angular performs, making your app faster.

7. **Server Side Rendering** 💻
– If our website need server side rendering and SEO for the pages, use SSR with Angular Universal.

8. **Caching for performance** ⚡
We can also optimise App performance by using memory caching or redis cache in Angular. It reduces http requests & minimise load times.

9. **Unit and E2E Testing** ✅
– Write unit tests for your components and services using Jasmine/Karma. For end-to-end testing, use Protractor. Testing ensures your code works as expected and prevents regressions.

10. **Consistent Code Style** ✨
– Adopt a consistent coding style and follow Angular Style Guide. Tools like Prettier and TSLint can help enforce these standards.

11. **Documentation and Comments** 📝
– Document your code and write meaningful comments. This helps others (and your future self) understand the purpose and functionality of your code.

At Ncoresoft we follow these Angular & Typescript best practices day in day out, so you can also build robust, scalable, and maintainable Angular applications.
