Optimizing ReactJS For Better Development

ReactJS is a framework to bring dynamism to static web pages. It works on multiple platforms. JavaScript library is the primary component that is flexible enough to integrate with various frameworks for improved performance. It defines single-page applications. It is preferable with hybrid applications with multiple content placeholders and elements in one web page. So that every time a value changes, the page does not necessarily reload. It is extensible, simple and highly performant. React is built up of a JavaScript library for creating interactive user interfaces with on-screen menus, search bars, buttons, forms, drop-downs, multi-line textboxes in a website or app. It integrates JSX, Virtual DOM, developer tools JS Engine, code reusability adding to an overall JavaScript appeal. For all this and more, ReactJS accounts for faster and effective deployment of web projects.

You can follow some tips to extract the maximum benefit out of ReactJS development:

• React DevTools help in faster debugging. It is tagged as a Firefox and Chrome browser extension and makes it easy to examine the list of React Components tree that has built the page of a particular application. React DevTools enable components tab in the developer tools. DOM’s tree has an extensive codebase where components are not labelled, but the tool’s ‘component’ – allows developers to view, inspect the state, props and hooks of the ‘component’ in real-time. It eases debugging and fastens the resolution process. It is used for performance analysis with the help of profiler – Flamegraph and ranked chart makes React DevTools a pragmatic extension.

• Error Boundaries: Component rendering results in an unexpected error, which un-mounts the components. But you can avoid such situations with error boundaries. It helps you identify and catch the JavaScript errors located anywhere in the child components tree. It also displays a fallback interface that makes it easy to handle ‘errors’; Please note that only class components have error boundaries. It captures the errors in only those components that fall below them in the tree. It cannot catch the error within itself.

• Use React & Typescript: React forms a power couple with TypeScript for faster application development, activates complex type definitions and robust interfaces, has extensive community support, stage refactoring and navigating the code to the next level (React to VS).

• Use Jest and Enzyme for Testing: These are the testing frameworks. If used judiciously, these prove helpful in React application development process; These are fast and completes tests fast, have a comprehensive mocking library, controls dependencies, controls master time, controls timer functions, support ES6 classes and perform snapshot testing. Besides, Enzyme is a JavaScript Testing Tool that renders multiple components, navigates and interacts with the elements, leveraging the benefits of virtual DOM simultaneously. ReactJS developers often use them together for an improved ReactJS development.

• Splitting the ‘Code‘ is used for segregating the codebase into component bundles. It minimizes the amount of ‘code’ needed for compilation, resulting in faster page loading. It also helps in lazy loading in which only the components currently in use load. Single-page React applications use tools such as Webpack, Browserify, Rollup to bundle files together. Splitting the ‘code’ improves performance and brings a better development experience.

• The use of a content delivery network improves the speed and functionality of the website. A responsive website with an interactive user interface accelerates React potential and delivers a great user experience. It reduces the distance between servers and website visitors. It escalates the loading speed as the time required to load the content is reduced.

• Use CSS Animation Instead of JavaScript Animation as it has self-contained and UI elements. So it’s better to introduce a tooltip, navigation menu, or show movement on-screen; If you want to build simple transitions like toggling states of UI elements and deliver the exact required design without crashing the web browser or locking the user interface. Moreover, get much more control over the animation duration, iterations and change multiple properties simultaneously.

• Activate Gzip Compressionto compress the files of any type like plain text and images for rapid transfers and enhanced web performance. It uses lossless compression that enables the webserver to load the files faster on the front-end. As Gzip reduces the file size by 50-70% of the original file and boosts the application performance, it is advantageous for SEO.

• Web Workers enable the browser to run scripts in the background and allow the web application to execute multiple tasks synchronously to handle animations, handling DOM elements, manipulating response data, directing UI interactions, and much more. It provides extra worker threads to pulling off the workload out of the main ‘thread’; executes processes separately. These perform tasks without interfering with the main ‘thread’ reducing the execution load over the main ‘thread’; it speeds up rendering and manipulation;

• Every time an Inline function is called – it requires a render method and creates a new function instance. React uses Virtual DOM to make DOM updates. It creates a new ‘instance’ of the function each time during virtual DOM diffing. This direct binding of the inline function generates an extra load over the garbage collector (binding a new ‘function’ to the DOM). It creates unnecessary updates. Creating a ‘function’ inside the component avoids this. A new instance of the ‘function’ is not created each time during render, reducing the processing and improving performance.

Conclusive: Why prefer ReactJS for cross-platform app development?

ReactJS streamlines web projects and mobile applications by scaling with the needs of the hour. It makes coordination and communication easy, effective, and impressive. Therefore, it is suitable for projects with strict time frames, complex problems that require a reliable and quick solution. We highly recommend ReactJS development services as this framework has been bettering debugging and providing more open-source components.
