It’s time for your next web development project and you’ve got the best idea in mind and a top team assembled. Now, all that’s left is choosing the right JS framework to make it happen. That’s easier said than done. Web development is a popular field, and the number of tools is increasing to match demand. Still, the two names that keep rising to the top are React and Angular.
While the two frameworks operate in different ways, there are more similarities than you might think. But which one would be the best for your project? Read on to find out more about both frameworks and some useful pointers to help you make the best possible decision for your next development project.
React: Light and Flexible
React is best described as an open-source front-end JavaScript (JS) library. It was developed by a team at Facebook (now Meta) and made open-source in 2013. Its name comes from the code’s ability to “react” dynamically to data changes.
What Is React?
React’s framework is designed for the development of single-page apps and mobile apps, complete with an array of features. It breaks down complex interfaces into smaller reusable components, allowing team members to work on separate areas simultaneously. Its JS-based library means that React is easy to learn, with a low barrier of entry for any developer.
Key Features
React’s many features were designed to give developers greater flexibility and freedom when designing scalable projects. Its component-based nature also makes it comparatively lightweight to use. Here are some of the major features offered:
- Reusable components: React’s component-based design means that multiple parts of the application can reuse component code, assuring faster coding for developers and better project organization.
- One-way data binding: React uses a parent-to-child hierarchy for its data propagation. While this may not be as efficient in adjusting variables as two-way binding, it makes it easier for developers to hunt down bugs and trace updates. One-way binding also doesn’t need constant reloading, meaning the project can be broken up more easily.
- Server-side rendering: While not included by default with React, server-side rendering is easy to configure through ReactDOMServer. The two main benefits of leaving the server to render are increased page load speeds and enhanced SEO capabilities. What’s more, both client-side and server-side code are very similar, meaning less work for developers.
- Virtual DOM: Perhaps React’s biggest selling point is its virtual document object model (DOM). Whenever an element is updated, a real DOM would have to update the entire tree structure to display the new UI. React skirts this by allowing single elements to update as required, saving time and processing resources.
- Community and support: As part of the Metaverse, React has a well-established community of volunteers, professionals, and enthusiasts. There are guides, third-party libraries, and various resources to help developers find solutions and save time.
It’s also worth noting that besides JS, React can utilize JSX to create components and write HTML-like code.
Drawbacks
Although React is a highly flexible and versatile framework, this looseness can also work against it, making it challenging for newcomers to initially set up and navigate its many tools and additional libraries. As the ways of using React can vary wildly, coordinating different teams and their varying standards can also be a hindrance.
Angular: Robust and Powerful
Angular is a type-script-based framework developed by Google to replace the older AngularJS in 2010. It’s robust and inclusive, carrying many of the libraries, tools, and features most commonly used by developers. In contrast to React, it’s much more rigid in the way it allows web pages and applications to be developed.
Key Features
Angular uses its Typescript language (a superset of JS) to create highly scalable and complex cross-platform web and mobile apps. Its robust and centralized design means errors are few and that code can be reliably constructed to certain standards, regardless of development teams. Here are a few key features that set it apart:
- Modular and component-based design: Early versions of Angular were distinguished by their modular nature. The model-view-controller (MVC) architectural pattern enables the breakup of projects into smaller parts for easier development by teams. More recent versions have supplemented this with the component-based architecture found in React. Both are popular.
- Tools and libraries: Angular comes complete with a multitude of extra elements to supplement any design. Angular CLI provides a handy interface for desktop developers, while test runners like Karma and Jasmine enhance the debugging process. Others, like NgRx, help build reactive apps.
- Two-way data binding: Unlike React, Angular makes use of two-way binding. Any change made to one element will automatically be updated with others. This flow also instantly tracks changes and propagates information between the UI and the data model. While this constant updating may be heavier on costs and processing power, it can be a more efficient way of keeping all elements in sync.
- Dependency injection: Larger projects can get complicated quickly. The dependencies between various components and services of an application can become equally muddied. Angular’s stronger framework allows for a dependency injection feature, enabling these elements to declare their own dependencies and freeing developers from needing to keep track.
Angular’s type-script language must be translated to JS code when the application is compiled. The ahead-of-time (AOT) compilation negates this lengthy load time and optimizes this process before a build by reducing code size and streamlining the conversion process.
Drawbacks
Just like React, Angular’s nature makes for its biggest drawbacks. The type-script language has many quirks unique to the framework, and the more inclusive system makes for a steep initial learning curve.
As a heavier framework than React, processing speed is also an issue with Angular. Two-way data binding and a range of features can slow down less powerful systems. That said, various optimizations like AOT and Jasmine go a long way in mitigating this drop-off.
React vs. Angular: Making the Choice
Now that you understand both frameworks better, it’s time to see which would be best for your next development project. Both React and Angular are very popular and easily scalable. Your choice will depend on a few factors.
Data Binding
Angular’s two-way data binding is more efficient upfront than React’s one-way data binding. While instantly updating UIs and design consistency across all elements can be a big bonus, they aren’t necessarily the final word. If you’re looking to trace changes and debug more easily, then the parent-to-child hierarchy of React can be a better choice. It’s also an easier way to control data flow in a team environment and lightens processing speed.
Code Quality
React is a lightweight framework that’s simple to learn. Because of its flexibility and nebulous structure, there are many varying standards when it comes to building a webpage or application. This can be frustrating when trying to coordinate a large development team with different ways of working.
In contrast, Angular’s opinionated modules, components, and services make thorough coding standardized through an established structure. Code standards can also be enforced through various tools. For example, Linters can reduce human errors through coding and streamline the development process.
Server-Side Rendering
Server-side rendering (SSR) is vital in reducing load times and enhancing SEO. React doesn’t include this by default and relies on ReactDOMServer to get the job done. RenderToString can also be used to avoid the render in as many instances as possible. On the other hand, Angular comes equipped with Angular Universal to pre-render code. You can easily access static shots of the app before it’s fully rendered.
Bundle Size and Loading Times
When it comes to bundle size and load times, the lightweight framework of React will always come out tops. Angular has larger bundle sizes and, therefore, longer load times but comes with extra features to accommodate and lessen this delay. Angular CLI optimizes code, reduces bundle size, and can use AOT to perform valuable pre-rendering. Its robust nature is also designed to handle larger projects better.
Both React and Angular can implement bundling tools to remove any unnecessary or unused code during the bundling process. What’s more, tools like React.lazy can dynamically split code for React, loading only necessary code for the already lightweight framework.
Performance of DOMs
The DOM is a central part of any development project; it allows you to see what the user will see when using the webpage or app. Any change in the UI or code will be reflected in the DOM, but to what extent depends on the framework. Angular uses a real DOM, which is updated every time a change is made. This is understandably heavy on processing and quite slow at times.
React shines in this aspect through its use of a virtual DOM, which only updates changed elements. This drastically speeds up development and makes testing a much simpler process. Combine this with React’s reusable components, and you’ll have a much faster development. If speed and processing are important, React is the way to go.
Consulting the Team
Any development project relies heavily on the expertise of its team. What framework is your team the most comfortable with? While both frameworks are JS enabled, developers will also need to be familiar with Type-Script for Angular. React developers must all be on the same page regarding development standards and what libraries to use. Always consult with members beforehand.
Making the Choice
Both React and Angular are popular and solid framework options that are well supported by both their companies and communities. While Angular can handle bigger tasks and is more self-contained, React is flexible and easy to learn. Both are good choices, yet your choice will ultimately depend on your project and team. You should now have all the information you need to help you make the best decision possible.
