Top 20 Crucial Angular Best Practices to Embrace in 2023

Angular is a powerful open-source web application framework developed and maintained by Google. It is designed to simplify and streamline the process of building dynamic and interactive web applications. 

Angular was first introduced in 2010 as "AngularJS" by Misko Hevery and Adam Abrons during their work on a project called "GetAngular." It gained significant traction in the web development community due to its innovative two-way data binding and declarative approach to building user interfaces.

With its robust features and comprehensive set of tools, Angular has become one of the most popular frameworks for front-end web development. Angular has become one of the most popular and powerful frameworks for building dynamic and scalable web applications. 

Angularjs development services have continued to evolve, with regular updates and new versions released to provide developers with cutting-edge features and tools to build complex web applications with ease.

Key Features of Angular

  1. Component-Based Architecture: Angular follows a component-based architecture, where each UI element is represented by a component. Components encapsulate the HTML, CSS, and logic, making it easier to manage and reuse code.

  2. Two-Way Data Binding: Angular offers powerful two-way data binding, allowing changes in the model to automatically update the view and vice versa. This feature simplifies the synchronization between the data model and the user interface.

  3. Directives: Directives in Angular enable developers to extend HTML with custom elements and attributes. Built-in directives like ngIf, ngFor, and ngStyle enhance the development experience and make the code more expressive.

  4. Dependency Injection: Angular's built-in dependency injection system facilitates the management of application components and their dependencies, promoting modularity and testability.

  5. Routing: Angular provides a robust routing mechanism, enabling developers to create single-page applications (SPAs) with multiple views and navigation without reloading the entire page.

  6. Forms: Angular offers two form handling approaches: Template-driven forms and Reactive forms. These features simplify form validation, data binding, and form submission.

  7. RxJS Integration: Angular integrates seamlessly with RxJS, a reactive programming library that enables efficient handling of asynchronous operations and event streams.

  8. Cross-Platform Development: With Angular, developers can create not only web applications but also cross-platform mobile applications and desktop applications using tools like NativeScript and Electron.

  9. Angular CLI: The Angular Command Line Interface (CLI) provides developers with a set of powerful tools to scaffold projects, generate components, services, modules, and handle the development workflow efficiently.

  10. Angular Material: Angular Material is a UI component library by the Angular team, implementing Material Design guidelines. It offers a suite of pre-built, customizable components to enhance the look and feel of applications.

Top Angular Best Practices to Adopt in 2023


As we venture into 2023, it's crucial for developers to stay up-to-date with the best practices in Angular to ensure efficient and maintainable code. Let’s explore the top 20 Angular best practices to adopt in 2023, enabling you to deliver high-quality applications and enhance your development workflow.

  1. Use Angular CLI

Angular CLI (Command Line Interface) is a powerful tool that streamlines the process of creating, testing, and deploying Angular applications. Utilize Angular CLI to bootstrap projects, generate components, services, and modules, as well as for efficient code scaffolding.

  1. Upgrade to the Latest Angular Version

Staying up-to-date with the latest Angular version is essential to access new features, bug fixes, and security updates. Regularly upgrade your Angular projects to ensure they benefit from the latest improvements.

  1. Follow the Single Responsibility Principle

Adhere to the Single Responsibility Principle (SRP) when designing components and services. Each component should have a single responsibility, making the codebase more maintainable and easier to debug.

  1. Optimize Change Detection

Angular's change detection is a powerful mechanism, but it can also lead to performance issues. Use OnPush change detection strategy judiciously to minimize unnecessary checks and improve application performance.

  1. Lazy Load Modules

Employ lazy loading to load modules only when they are required, reducing the initial load time and enhancing the overall application performance.

  1. Use AOT Compilation

Ahead-of-Time (AOT) compilation helps to reduce the bundle size, leading to faster loading times for your application.

  1. Follow a Consistent Folder Structure

Organize your Angular project with a consistent folder structure to maintain a clear separation of concerns and ease collaboration among team members.

  1. Leverage Reactive Programming

Use RxJS to implement reactive programming in Angular, enabling efficient handling of asynchronous operations and simplifying data flow management.

  1. Minimize the Use of ngIf and ngFor

While ngIf and ngFor are handy directives, overusing them can negatively impact performance. Minimize their usage, especially when dealing with a large number of elements.

  1. Implement ARIA Accessibility

Make your Angular applications more accessible by implementing ARIA attributes and following accessibility best practices.

  1. Optimize Bundling and Tree Shaking

Leverage tree shaking to remove unused code from your bundles and optimize the application size for better performance.

  1. Proper Error Handling

Implement robust error handling mechanisms to provide meaningful error messages and avoid crashes that could negatively impact the user experience.

  1. Use Angular Interceptors

Angular interceptors are great for handling HTTP requests and responses centrally. Utilize them to add headers, handle errors, and manage loading indicators.

  1. Apply Angular Forms Effectively

Angular provides powerful form handling capabilities. Ensure you're using template-driven or reactive forms appropriately based on your application requirements.

  1. Perform Unit Testing

Write comprehensive unit tests for your components, services, and directives to maintain code quality and reduce the chances of regressions.

  1. Implement Server-Side Rendering (SSR)

For improved SEO and performance, consider implementing Server-Side Rendering to render Angular applications on the server side before sending them to the client.

  1. Utilize Angular Material

Angular Material is a UI component library by the Angular team. It provides a set of ready-to-use components that follow Material Design principles, speeding up development and maintaining a consistent look and feel.

  1. Keep Third-Party Libraries Updated

Regularly update third-party libraries and dependencies to avoid security vulnerabilities and benefit from the latest features and bug fixes.

  1. Implement Content Security Policy (CSP)

Employ Content Security Policy to protect your application from cross-site scripting (XSS) attacks and improve its security.

  1. Monitor Application Performance

Utilize tools like Angular DevTools and Lighthouse to monitor and optimize your application's performance continually.


By embracing these top 20 crucial Angular best practices in 2023, you can enhance your development workflow, build more efficient and maintainable applications, and keep up with the ever-evolving Angular ecosystem. Staying vigilant about updates, security, and performance optimization will help you create cutting-edge web applications that provide an exceptional user experience.

From startups to enterprises, businesses across the globe are leveraging AngularJS development services to build scalable and robust applications that engage users and enhance their online presence.
