Reasons to choose ReactJS for your project
With the fast-paced digital world, IT companies can no longer rely on obsolete programming languages to develop applications and websites. These languages are not only complex to deal with but also require immense effort to write scalable, flexible, and adaptable codes. This primarily has shifted the paradigm in the industry, compelling developers to adopt new languages and platforms that can ease the development work and open a host of new opportunities. One such language that has become a prominent choice for every tech stack used in custom mobile app development is ReactJS.
In 2011, Facebook faced immense difficulties in meeting its user demands due to the complex app architecture and front-end modeling. Even though the company wanted to offer a rich user experience to everyone, the integrated UI structure prevented the developers from creating a dynamic and responsive front end. It was then Jordan Walke made a new programming library, which finally came to be known as ReactJS.
It is a JavaScript-based library used in front-end development to create a dynamic and interactive user interface. Unlike regular JS-based front-end languages, React allows developers to leverage small modules or components to develop the entire UI. The framework is primarily responsible for handling the View layer on the application through best-in-breed rendering execution.
In ideal cases, the entire user interface is treated as a single, integrated unit, making it difficult to scale the features or deploy rapid changes. But while using ReactJS, the interface is segregated into smaller modules, each handled through reusable UI components, thereby allowing developers to create a far more responsive and more prosperous front-end for mobile and web apps.
To get a full grasp of ReactJS, it is crucial to understand its working mechanism. This way, you can differentiate between this JavaScript-based library and other JS-powered frameworks like VueJS and AngularJS. Let’s assume you want to open a particular website on your browser. For this, you will enter its URL first, which resembles the specific site page you wish to display.
Once you give the URL, your browser (Client) sends the request to the server where the website is hosted and renders the response for displaying all the components on the interface. Now, let’s say you have clicked a hyperlink or want to visit another web page; the client side will again request the server and fetch the web page. Even though this approach of back-and-forth page loading is popular for standard websites, it lacks efficiency for webpages with large datasets or dynamically changing data.
In the latter cases, the client side needs to reload the entire page multiple times as and when any data change is detected. Due to a full reload, the loading time increases and the page becomes slower. To overcome the difficulties, ReactJS is used as the front-end development language. It enables developers to create SPAs or single-page applications where only one HTML page is loaded on the browser at the first request.
React creates a virtual DOM in its memory, which is nothing but the replica of the web page’s original DOM. As the data state changes, React updates its virtual DOM and compares the same with the webpage’s actual DOM. Based on the changes, it fetches only that section and updates the components to render the modifications on the interface. This prevents the full reload of the webpage through manual DOM manipulation, enhancing the overall user experience.
What features make ReactJS perfect for front-end development?
Below, we have discussed a few features of ReactJS that make it different from other frameworks powered by JavaScript. These illustrations will give you an in-depth idea about this JS-powered library used popularly for web and mobile app development. As a web application development company, you must be aware of the features before integrating React into the tech stack for your upcoming project.
Unlike the conventional JavaScript-based development frameworks, React uses a combination of HTML and JavaScript syntaxes, namely JSX or JavaScript Syntax Extension. It allows embedding of the JS objects inside the HTML elements for more straightforward evaluation and less complexity. However, it is essential to remember here that the browsers cannot transcribe JSX, which is why a Babel compiler needs to be integrated with the IDE. It transcodes the JSX codes into a JavaScript document and then performs the necessary actions.
React uses a virtual DOM or Document Object Model to handle the updates and make changes in the webpage accordingly. It first creates the virtual DOM by replicating the original DOM and then makes changes in the former according to the state changes of its components. Once done, it compares the tree structure of the virtual and actual DOMs and makes changes in the latter. Since ReactJS only works on the specific area of the actual DOM where the change is required, the entire web page is not reloaded, thereby optimizing the load time and keeping the working pace faster.
React works on the principle of one-way data binding, where data can flow unidirectionally, from the top to the bottom. In other words, data transfer happens from the parent to its child components only. The child components cannot return the data to the parent. However, it can communicate with the parent component to change its state based on the provided inputs and rendering execution.
React comes with multiple extensions that can be added to your system or browser for creating a complete development setup. For instance, you can extend it to React Native to develop mobile apps for multiple operating systems using a single codebase while ensuring native features can be integrated. That’s why most companies offering Android and iOS application development services opt for React Native to develop applications with native features. Similarly, you can add the IDE extension of React, also known as Reactide, which will allow you to create a full-fledged and highly-performing UI for the application.
One of the main features of React that can be leveraged to amplify the success of your web or mobile application development project is component-based code architecture. The entire codebase is divided into multiple components, each handling a separate segment of the UI. These components interact with one another through data binding and rendering. Furthermore, they function independently, and the data state also changes without impacting other components handling the UI features.
Why Choosing ReactJS is Ideal For Your Project?
Modularity and Scalability
Unlike other JavaScript-based libraries and frameworks, ReactJS utilizes a component-based architecture. A typical user interface comprises several segments, like the header, sliders, images, textual content, and so on. Several segments of the website or mobile app are static, which means they won’t change as you move from one page to another, while others are dynamic. It is pretty challenging to develop the dynamic UI segments since they need to be rendered now and then once a state change is detected in the cache or DOM. This is where React seems to be a more feasible option due to its modularity and scalability.
Codes are written in component forms, where each component is responsible for rendering a specific function or segment of the user interface. Any change in the element won’t impact other areas of the UI, thereby ensuring the dynamic balance is maintained till the very end. Furthermore, if you want to make any change to the UI, you don’t have to go through the entire codebase. Instead, you can focus on the component section handling that function or UI feature. Such a high level of modularity helps developers to write codes with minimal flaws within a much shorter time.
Rendering is a process through which the React component is converted into HTML code and further executed for displaying the UI feature or updating the DOM. In usual JavaScript-based frameworks, rendering is a time-consuming and complicated process because any change in the data triggers a complete reload of the page. To avoid this issue, React handles rendering through the virtual DOM. First, when the page loads for the first time on the client’s browser or system, a virtual DOM is created as a replica of the original DOM.
Whenever any state of the component changes, the virtual DOM is updated instantly. React then compares this virtual DOM and the actual DOM of the page and updates the latter accordingly. Instead of reloading the entire page, it fetches the section that needs to be updated and consequently makes modifications to the HTML code. Once done, it pushes the updated HTML section in the actual DOM through data patching, and you can see the change in the UI. Since the entire page is not reloaded, the rendering process in React is relatively fast and seamless.
Enhanced code structure stability
In ReactJS, codes are written in the tree structure, where a proper hierarchy is established between parent and child components. Data flows unidirectionally, from the top to the bottom only. As a result, parent components can send data to their child components but not the other way around. So, if there is any bug or error in the child component, its parent won’t be impacted, and the page will still load with the features handled through the parent components.
This is one of the reasons for the high stability witnessed in ReactJS codes. Furthermore, if you want to make any changes to the React-based APIs communicating between the server and client sides, you just need to work on specific components. Since the entire code is not changed, stability is established in every software page handled through React.
The learning curve of ReactJS is relatively smooth, ensuring developers can learn the library and its functions in much less time. Firstly, scripting in React is done through HTML syntaxes, which is why writing the codes won’t be much of a problem. Secondly, the library comes with built-in functions that can be easily used to make codes more streamlined. As a developer, you can quickly develop complex UI features using React, which is indeed a plus point for large-scale mobile app or website development projects.
Search engines rank the websites based on the indexes assigned through crawling activity. If the website is complex and more challenging to crawl, the ranking is significantly impacted, and the website won’t be able to rank at the top. However, with React, this problem can be easily avoided as the library utilizes a lightweight code structure to handle the user interface on the client’s side. The crawler algorithm can easily trace the HTML code rendered through the virtual DOM, which is why most websites designed through React rank higher in the search engine page results.
One of the main advantages of ReactJS for modern-day mobile app and website development projects is code reusability. The components defined in the code structure can be reused to develop new functionalities instead of writing them from scratch. It not only reduces the development time but also allows developers to focus on more complex areas of the software development project.
Now that you know about the plus points of integrating ReactJS in your tech stack for your upcoming projects, ensure to Hire dedicated React developers from BOSC Tech Labs who can add more value to the software development activity. Also, it would be best to pair React with other frameworks and IDEs that can be used as extensions. This way, you won’t have to develop the APIs explicitly for communicating between all these platforms.
