What's New in React 19, Angular 18, and Vue 3.4 - Why I choose Angular

When it comes to building modern web applications, three frameworks/libraries often come to mind: React/Next, Angular, and Vue/Nuxt. Each has its own strengths and weaknesses, and developers often have strong preferences based on their experiences and project needs. Today, I want to delve into what's new in the latest versions of these frameworks—React 19, Angular 18, and Vue 3.4—and share why Angular remains my favorite.

Introduction to Each Framework

React: Created by Facebook, React is a JavaScript library for building user interfaces. Its component-based architecture allows for the development of reusable UI components. React's virtual DOM ensures efficient updates, making it ideal for single-page applications where performance is critical.

Angular: Developed and maintained by Google, Angular is a full-fledged framework that offers a complete solution for building web applications. It uses TypeScript, a statically typed superset of JavaScript, which enhances code quality and maintainability. Angular’s robust features include two-way data binding, dependency injection, and a powerful CLI.

Vue: Vue is a progressive framework for building user interfaces. Created by Evan You, Vue is known for its gentle learning curve and flexibility. It can be used for anything from enhancing a simple web page to developing complex single-page applications.

Pros and Cons

  • DevTools Enhancements: Improved Vue DevTools with new debugging features and performance monitoring.

Why Angular is still my go-to framework for large-scale projects

In my opinion, Angular stands out when it comes to large projects because of its structured and opinionated approach. Here’s why I believe Angular offers a superior developer experience:

Separation of Concerns

Angular enforces a clear separation of concerns, promoting organized and maintainable code. Components, services, and modules each have distinct roles, making the codebase more predictable and easier to navigate. This clear distinction helps in managing larger applications by dividing them into smaller, more manageable parts.

Monorepos

Angular works seamlessly with monorepos, which I believe is essential for large-scale projects. The Angular CLI supports workspace management, making it easy to share code between multiple projects and maintain consistency across a large codebase. This setup is particularly beneficial for organizations that manage multiple applications or libraries within a single repository.

Professional and Organized

Angular’s comprehensive nature makes it feel more professional and organized. The framework’s strong opinions about application structure and best practices guide developers towards writing clean, maintainable code. The Angular CLI also enforces best practices and provides a suite of tools that streamline development, testing, and deployment processes.

TypeScript

Angular’s use of TypeScript is a game-changer. TypeScript’s static typing helps catch errors early in the development process, leading to more robust and reliable applications. I find that TypeScript enhances my productivity by providing better tooling and autocompletion in my IDE. The type safety and advanced features like interfaces and decorators help in building scalable applications with fewer bugs.

Batteries Included

Angular comes with a rich set of built-in tools and features that cover a wide range of application needs, reducing the dependency on external libraries and ensuring a more cohesive development experience:

  • i18n (Internationalization): Angular's built-in internationalization support makes it straightforward to develop applications that can reach a global audience. The framework provides tools to handle translations, locale data, and currency formatting, ensuring your app can easily adapt to different languages and regions.
  • Routing: Angular's powerful router is another standout feature. It provides advanced functionalities like lazy loading, nested routes, and guard services. These features make it easy to manage complex navigation and improve application performance by loading modules only when needed.
  • SSR (Server-Side Rendering): Angular Universal enables server-side rendering, which can significantly enhance the performance and SEO of your application. SSR helps in faster initial page loads and provides a better user experience, especially for content-heavy applications.
  • HttpClient: Angular's HttpClient module simplifies HTTP requests with a fluent API. It includes built-in support for handling requests and responses, interceptors for modifying requests, and extensive capabilities for error handling and testing. This module helps in building robust communication with backend services with minimal effort.

Router Guards with canActivate

One of the features that sets Angular apart is its robust routing system, specifically the router guards. Angular's canActivate guard allows developers to control access to different parts of the application based on specific conditions. This built-in functionality is more powerful and integrated than the middleware solutions offered by frameworks like Next.js and Nuxt.js.

In Angular, canActivate guards can be used to protect routes by checking authentication status, user roles, permissions, or any other custom logic before the route is activated. This ensures that users cannot navigate to unauthorized routes, providing an extra layer of security and control. The seamless integration of canActivate within Angular's router makes it a more cohesive and reliable solution compared to the middleware approach in Next and Nuxt, which often comes down to weird switch and if/else blocks inside one function for your whole app.

This level of control and ease of implementation enhances the developer experience, allowing for more secure and maintainable routing in complex applications.

Angular CDK

The Angular Component Dev Kit (CDK) provides a set of tools for building custom components without reinventing the wheel. The CDK includes utilities for accessibility, overlay positioning, drag-and-drop functionality, and more. I find that the CDK makes it incredibly easy to create high-quality, reusable components that adhere to best practices. It abstracts away the complexities involved in implementing common component behaviors, allowing developers to focus on building unique and feature-rich components with ease.

Transparency and Control

Another reason why I prefer Angular is the level of transparency and control it offers to developers. In Angular, you as a developer are more directly responsible for how things work, with fewer hidden layers and abstractions. This clarity ensures that you have a thorough understanding of your application's inner workings, making it easier to debug, update, and optimize your components.

Unlike some frameworks where significant portions of the behavior are abstracted away and hidden, Angular’s explicit and declarative nature means that most of the application logic is laid out clearly in the code. This approach reduces the complexity often associated with "magic" happening behind the scenes, which can be a common frustration in other frameworks (according always to my opinion).

By having more direct control over the framework's operations, you can more easily track down issues, understand performance bottlenecks, and implement improvements. This transparency not only boosts your confidence as a developer but also results in a more maintainable and scalable codebase.

Summary

Ultimately, the right framework or library to use depends on your specific needs and the nature of your project. React’s flexibility and performance make it ideal for dynamic, high-performance applications. Vue’s simplicity and gentle learning curve are perfect for smaller projects or for developers new to modern JavaScript frameworks. Angular’s robustness, structured approach, and rich set of built-in features shine in large-scale, enterprise-level applications. Each framework has its unique strengths, and choosing the right one involves considering your project requirements, team expertise, and long-term maintenance goals. In my opinion, Angular's holistic approach and professional tooling make it the best choice for building complex, maintainable, and scalable applications.
