Should you use feedback for your next website? – Cloud CV IT

The popularity of the reaction has increased in recent years. Described as a “JavaScript library for creating user interfaces”, React’s declared approach to rendering simplifies the construction of complex UIs.

Responsive is a versatile tool with a wide range of applications, ranging from traditional websites to sophisticated web apps. There is no clear line that explains when you should use the reaction. Instead, there are guideline indicators that can help you gauge whether the reaction might be a good fit.

Find the ingredients.

One sign that the site may benefit from feedback is if you plan to reuse a large number of self-made components. ABSTRACT Interface elements such as form control and data display card are important candidates for change in reactive components. This is especially true if your components add custom behavior outside of the browser supply.

The nature of the response encourages you to separate the reusable aspects of your interface into individual components. Components are usually described in their own source files, making it easy to navigate and manage your code base.

import React from "react";
import ReactDOM from "react-dom";
 
class ChildComponent extends React.Component {
 
    render() {
        return <h2>Child Component</h2>;
    }
 
}
 
class DemoComponent extends React.Component {
 
    render() {
        return (
            <div>
                <h1>Demo Component</h1>
                <ChildComponent />
            </div>
        );
    }
 
}
 
ReactDOM.render(<DemoComponent />, document.body);

Components may include other components to enable faster construction of complex UIs. A component can offer some UIs, implement custom CSS styles, and handle JavaScript-based user interactions. React uses a custom templating language, JSX, to create partial UIs that look like regular HTML.

Find state segments.

Excellent performance in handling areas of your interface that offer different ways to value some internal condition. The idea of ​​a “state” seems vague at first. However, it’s easy to identify the state segments of your site – these are usually the areas that make the UI changes.

Examples include the value of a form input, whether a toggle button is selected, and the loading status of dynamically loaded content. Content itself is often delivered “state-of-the-art” – a typical blog post screen will display article data stored in the component’s internal state.

In the example below, the value of the text on the screen is determined. demo Key in component state. The text changes automatically every five seconds by updating the state.

import React from "react";
import ReactDOM from "react-dom";
 
class DemoComponent extends React.Component {
 
    constructor(props) {
        super(props);
 
        this.state = {
 
            demo: 1
 
        };
 
        this.timer = null;
 
        this.updateText = this.updateText.bind(this);
 
    }
 
    componentDidMount() {
        this.timer = setInterval(this.updateText, 5000);
    }
 
    componentWillUnmount() {
        if (this.timer) clearInterval(this.timer);
    }
 
    updateText() {
        this.setState({demo: (this.state.demo + 1)})
    }
 
    render() {
        return <h1>{this.state.demo}</h1>;
    }
 
}
 
ReactDOM.render(<DemoComponent />, document.body);

Try to find areas of your website that need to be dynamically changed. This could be the result of a user’s action, a recurring timer, or a browser event (such as going offline or fetching new background data).

Any statusfool section that is updated regularly is likely to benefit from the use of feedback. Smooth state management of feedback provides a source of truth for your site’s business logic.

Identify the interaction.

Feedback can make it easier to handle interactions within your website. The library summarizes JavaScript’s built-in event handlers to provide a unified interface to respond to user interactions.

The use of reactions can be especially beneficial in the case of complex forms. Its approach, based on “controlled components”, ensures that the internal state of the form matches what the user sees in the UI.

import React from "react";
import ReactDOM from "react-dom";
 
class DemoComponent extends React.Component {
 
    constructor(props) {
        super(props);
 
        this.state = {
 
            value: "I'm a text field"
 
        };
 
        this.updateValue = this.updateValue.bind(this);
 
    }
 
    updateValue(e) {
        this.setState({value: e.target.value});
    }
 
    render() {
        return <input onChange={this.updateValue} value={this.state.value} />;
    }
 
}
 
ReactDOM.render(<DemoComponent />, document.body);

By combining event handlers to create controls, you can update the state of the component whenever the user control value changes – such as by typing in a text field or selecting an option from the drop-down menu. Then, create controls. value prop (which creates HTML maps. value Description: Refer to the condition of the component. Changes to the UI and component will now appear in each other.

Find DOM manipulation.

It is a golden rule to consider when using React. Descriptive content, user interactions, and dynamically updated components all return to the DOM. Direct DOM manipulation using the browser’s JavaScript APIs is the best and worst of all.

Any aspect of your website that requires extensive DOM manipulation – these are the HTML elements displayed on the page – is a potential source of complexity. Reaction can make these scenarios much easier. Its component-based nature eliminates the difficulty of injecting HTML and handling event bindings.

Since the response is declarative, you specify what the DOM should look like inside a component. render() Method Library then works hard to create, remove and replace HTML elements in order to create the DOM structure that you have “announced”.

Internally, React maintains its “virtual DOM” which ensures that the whole process runs efficiently. This allows the library to perform the smallest number of reproductions possible, typically minimizing the overheads associated with DOM manipulation.

Result

The popularity of the reaction stems from the remarkable simplicity of state management and DOM manipulation it provides. Its declarative nature allows to build highly complex web applications like basic HTML pages, developers only need to know what the DOM structure should look like at the moment.

Like anything good, it has its downsides. Using React will increase the download size of your website. It also includes reliance on JavaScript which may prevent some users from accessing your content. There are far more failure points than “pure” HTML, CSS and JavaScript solutions.

These limitations mean that responsiveness may not be the best choice for simple static websites. Sites with small interactivity and limited DOM manipulation are better than sticking with a lightweight solution. The benefits of React really start to pay off on sites that have a lot of internal condition. Response improves developer productivity, code base maintenance, and overall site performance when used carefully on data-centric interactive sites.
