Choosing between React.js and Angular
June 10, 2021
This article discusses and compares the two most used front-end platforms; Angular and React.js.
Angular and React.js
|Ideal For||Creating highly interactive web applications||Creating large web applications with varying data|
|App Size||Relatively small||Relatively small|
|Dynamic UI Binding||UI binding at a plain object or property level||Direct linking of states to the UI|
Angular and React have gained much popularity in the recent past. Both have been featured in numerous discussions and forums. However, React.js has more users due to its earlier release, as well as a moderate learning curve.
Both React.js and Angular offer high performance. However, React.js is faster due to its one-way data binding. Angular, on the other hand, has numerous tools that help cut development time. For instance, Angular has a cacheFactory feature that helps store and retrieve data.
React.js, on the other hand, supports component reusability which is quite productive.
For instance, Angular has a dependency injection tool which assists in passing data between different components. In React.js, it is easy to conduct tests due to the availability of Mocking Functions.
React.js also comes with test runners such as Ava, Mocha, and Jest.
Jest is compatible with other features such as Mocked Node modules, Timers, and Jdsm. Furthermore, libraries such as Mocha can support simulations just like a real browser.
Angular CLI helps to improve code quality. It supports integrations from Angular Core and Angular Material.
React.js also has numerous plugins that increase the code quality. For instance, Linters uses a set of strict rules to ensure that there is consistency.
Angular is used when developing single-page applications. Such applications have complex structures, as well as several programming modules. To maintain such a complex structure, developers must choose a flexible and reliable framework.
React.js is better than Angular when writing clean code, especially when there are short deadlines. As stated, React.js allows developers to reuse numerous components and thus, save time.
Angular supports pre-rendering of views. However, developers can use both JSON and client-side caching to boost the server’s performance. Angular is much better when it comes to reducing traffic between client and server.
Angular also minimizes the need for recompiling. Since it updates UI components quickly in case of data changes.
For an application to have excellent SEO, it needs to be rendered on the server. React.js has specialized functions that support this feature. A perfect example is the RenderToString() method.
In addition, the renderToStaticMarkup() function can prevent the creation of Document Object Model (DOM) attributes such as data-react-id. These elements are responsible for creating a static page generator.
Optimizing the bundle size
Though working with single-page applications may seem easy, managing the bundle file size is quite challenging. Many websites have a low loading speed. This is because the bundle file has to be downloaded. This means that the site should be optimized as much as possible.
bundle size is essential when developing an enterprise application. Keeping the size small allows the website to run more smoothly. However, it may be difficult to maintain the size due to the addition of new features and dependencies.
Since Angular is quite broad, it has a steeper learning curve. New developers may find it difficult to cover some topics in Angular.
Reasons for using Angular
- It has inbuilt features such as AngularCLI and Rxjs which help in handling different events.
- It increases productivity by having fewer lines of code and components.
- It supports high-performance applications.
- It enhances rapid server-side rendering which improves user experience.
Reasons for using React.js
- It has dependencies such as Redux, which assist in the faster development of scalable applications.
- Routing is much easier in React.js through the use of ReactRouter.
Angular and React.js use cases
Both Angular and React.js have been used to develop popular applications in the world.
Below are two use cases for Angular and React.js:
For an application with a complex UI, React.js is simpler to use. React.js also has a shorter learning curve than Angular.
Depending on the project requirements, one can choose between Angular and React.js. For example, a developer can use React.js for short projects that require a smaller learning curve.
React.js is easy to use since the developer does not have to organize HTML code and can reuse UI components. On the other hand, when developing a vast application with extensive features, the team can go for Angular due to its extensive features.
