Angular – Things to avoid when you develop your first app


Developing your first Angular app can be an exciting but sometimes challenging experience. To help you navigate the process more smoothly, here are some common pitfalls and things to avoid when developing your first Angular app:

Neglecting to Understand the Basics

Ensure you have a solid understanding of the basics of Angular, including components, services, modules, templates, and data binding.

Skipping the Official Documentation

Angular has extensive documentation that is well-written and regularly updated. Avoid skipping the documentation, as it is a valuable resource for learning and troubleshooting.

Not Following Angular Best Practices

Adhere to Angular best practices, such as using a modular structure, following the Single Responsibility Principle, and using reactive programming with observables when appropriate.

Overcomplicating the Initial Setup

Keep your initial project setup simple. Avoid adding unnecessary libraries or configurations that may complicate the learning process.

Ignoring TypeScript

Angular is built with TypeScript, and leveraging TypeScript’s features, such as static typing, can catch errors early and improve code quality. Avoid ignoring or skipping TypeScript.

Not Using Angular CLI

Angular CLI (Command Line Interface) is a powerful tool that streamlines the development process. Avoid manually setting up your project without utilizing Angular CLI.

Neglecting Testing

Incorporate testing early in the development process. Writing unit tests and end-to-end tests can save time and ensure the reliability of your application.

Ignoring State Management

Understand the importance of state management, especially in larger applications. Explore and choose the appropriate state management solution, such as NgRx, if needed.

Not Paying Attention to Performance

Keep an eye on performance considerations, such as lazy loading modules, optimizing change detection, and minimizing unnecessary HTTP requests.

Ignoring Security Best Practices

Be mindful of security considerations, such as validating user input, protecting against cross-site scripting (XSS) attacks, and securing communication with backend services.

Not Considering Accessibility

Ensure your application is accessible to users with disabilities. Follow best practices for creating a user interface that is navigable and usable by everyone.

Forgetting about Mobile Responsiveness

Design your application with mobile responsiveness in mind. Angular Material provides components that are designed with responsiveness in consideration.

Not Keeping Dependencies Updated

Regularly update your project dependencies, including Angular itself and third-party libraries, to benefit from bug fixes, security patches, and new features.

By being aware of these common pitfalls and best practices, you can enhance the development experience and create a more maintainable and robust Angular application.
