Utilise Shadow DOM In React with All The Benefits of Style Encapsulation

Utilise Shadow DOM in React with all the benefits of style encapsulation.

npm: npm i react-shadow
yarn: yarn add react-shadow

Getting Started

Creating the shadow root is as simple as using the default export to construct a shadow root using the node name provided – for example root.div would create a div as the host element, and a shadow root as its immediate descendant — all of the child elements would then be descendants of the shadow boundary.

import root from 'react-shadow';
import styles from './styles.css';

export default function Quote() {
    return (
        <root.div className="quote">
            <q>There is strong shadow where there is much light.</q>
            <span className="author">― Johann Wolfgang von Goethe.</span>
            <style type="text/css">{styles}</style>
        </root.div>
    );
}

Applying styles requires either applying the styles directly to the component as a string, or importing the CSS documents as a string as part of your build process. You can then append the style component directly to your shadow boundary via your component’s tree. In the example we use the following Webpack configuration to import CSS documents as strings.

{
    test: /\.css$/,
    loader: ['to-string-loader', 'css-loader']
}

Alternatively you can use styled-components normally, as each time a shadow boundary is created, a new StyleSheetManager context is also created which will encapsulate all related styles in their corresponding shadow root — to use this import react-shadow/styled-components instead of import react-shadow, likewise if you’d like to use emotion you can import react-shadow/emotion.

import root from 'react-shadow/styled-components';
import root from 'react-shadow/emotion';

// ...

<root.section />;

You may pass any props you like to the root.* component which will be applied directly to the host element, including event handlers and class names. There are also a handful of options that are used for the attachShadow invocation.

ShadowRoot.propTypes = {
    mode: PropTypes.oneOf(['open', 'closed']),
    delegatesFocus: PropTypes.bool,
    styleSheets: PropTypes.arrayOf(PropTypes.instanceOf(global.CSSStyleSheet)),
    children: PropTypes.node,
};

ShadowRoot.defaultProps = {
    mode: 'open',
    delegatesFocus: false,
    styleSheets: [],
    children: null,
};

In cases where you need the underlying element and its associated shadow boundary, you can use a standard ref which will be invoked with the host element – from that you can use shadowRoot to access its shadow root if the mode has been set to the default open value.

const node = useRef(null);

// ...

<root.section ref={node} />;

Recently and at long last there has been some movement in introducing a declarative shadow DOM which react-shadow tentatively supports – as it’s experimental, open to sudden spec changes, and React finds it difficult to rehydrate – by using the ssr prop.

const node = useRef(null);

// ...

<root.section ssr />;

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

Performance: It delivers optimal performance.
Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
UI design: React Native enables you to design simple and responsive UI for your mobile app.
3rd party plugins: This framework supports 3rd party plugins.
Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
Near-native user experience: React Native provides several native components, and these are platform agnostic.
The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
React.js and React Native have similar syntax and workflows, but their implementation is quite different.
React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.

React is scalable. it utilises a single language, For server-client side, and mobile platform.

React is steady.React.js is completely adaptable, which means it seldom, if ever, updates the user interface. This enables legacy projects to be updated to the most new edition of React.js without having to change the codebase or make a few small changes.

React is adaptable. It can be conveniently paired with various state administrators (e.g., Redux, Flux, Alt or Reflux) and can be used to implement a number of architectural patterns.
