3 Tactics to Enhance React.JS App Performance

None of the businesses ever thought of losing potential consumer base by the bucket-load as a norm. It’s a detrimental condition hampering business growth and development. Now, imagine if your mobile enterprise app isn’t bug-free and not performing well then it will fail you in establishing an unrivaled brand worth.

Here comes an influential role of cross-platform React (JavaScript library) can play when combined with multiple components. It allows the developers to structure their code and introduce SoC (separation of concerns) in a better way. For this reason, it’s always recommended to business owners to outsource their web and mobile app projects to a reliable Android Application Development Company with a broad, commendable portfolio across all industries.

Adding to it, React.JS also allow the developers to reuse their codes across different sections in a web or mobile app. Facebook and Instagram are excellent examples wherein React is used to build a user interface, whether for a single-page web app or a mobile enterprise app, which is simple, speedy and scalable.

For instance, iOS calculator – a native built-in feature for Apple users is a React-based application. In websites, product comparison page is a pretty good example of building incredible user interfaces with the help of React framework.

In numerous ways, you can make simple alterations to fix the performance issues of a React-based application. For improved efficiency, as owner, you can get Software Development Firm brief them about your concerns and they will turn up with tailor-made solutions to meet your expectations. Poor application performance leads to absolute failure as it impedes the user experience and hence, needs a quick rectification.

If you do not want to trap in some weird code or doomed functionality as a newbie developer, then follow the following performance tips that will help you create a fast, clear-coded and high functionality React App.

Build a Compact Code Using Babel Compiler:  

Whatever app you will build on cross-platform React should employ modern JavaScript features to function smoothly in all runtimes and across all browsers. Babel Compiler is the best option for developing a cross-browser-compatible application. Babel compiles the codes with the help of a variety of plugins or Preset a default React plugin used as a compiler to write a next-gen JavaScript code.

Babel Presets work matchlessly for React Native apps. React Preset incorporates numerous ES6/2015 features and depending on your preference; you can use the latest ES7/8 presets. However, the Babel compiled code targets the older supported version for browsers, and therefore all of them gets the same code regardless of the version your React app needs to support.

Developers can enjoy complete control on how Babel assembles the required codes with the help of Babel-Preset-Env plugin. All you need is to make a simple entry in package.json file to activate the Env preset for targeted browsers you want your app to support.

With this powerful configuration, you can speed up not only the app performance but also the client-side downloads – ensuring a remarkable user experience.

Create Built-In Features in Target Browsers Through Polyfill.Io Script.

Although Babel is a great tool to improvise JavaScript language, it doesn’t support Polyfill codes used to implement new features in browsers. For new browser built-ins development, supporting the old versions of targeted browsers, the best option is to employ Polyfill.Io scripts.

Options Available:

Use Polyfills through libraries or you can create yourself and load as per requirement for a specific case.

Employ Polyfill.io library that operates according to a User-Agent header that identifies the browser, operating system and software vendor a visitor uses to access any application.

Professionals recommend the second method because it is easy to install and manage Polyfill.io library. Once placed accurately as you add the standard script to your root Html file of the main app it can easily load the required Polyfills so that you can use new browser built-ins with ease. Moreover, it can use API for loading the specific Polyfills you need.

Eliminate Dead-Codes through Tree-Shaking & Webpack 2+

Babel compiler and Polyfills allows to the developers to make React applications compact, coherent and hassle-free across all platforms. Besides, you need a code that doesn’t allow anything useless or obsolete to pop up while using the app. It means the need for consistent clearing of the source code, increasing its performance potential.

This removal of dead codes or in simple words removing the codes that are useless for the app and user experience is termed as Tree-Shaking. As the dead leaves start out falling the shaken tree, the older codes or things like third-party libraries need to leave the main app’s coding document.

It’s quite easy in case of React applications. Import the dependencies with the help of ES2015 module syntax and then use a Webpack 2 (or above) and a Minifier (e.g., Babel, Uglify JS, etc.) to support the tree-shaking process and ensuring the shipping of succinct and fastest code to the target browsers.

Let’s cut to the chase!

With these three strategic methods, a developer can make the React apps function swiftly and efficiently.
