6 Best Practices for React Component Design.

Component Design.

React is a well-liked library for building user interfaces that are written in JavaScript. It gives you a powerful set of tools for making reusable parts, which can help make the development process easier and make your app work better.

However, if you're new to the library, designing React components can be difficult.

In this article, we'll investigate a few prescribed procedures for the Response part plan that can assist you with making superior-grade, reusable parts that are not difficult to keep up with and scale.

1. Use Functional Components Whenever Possible.

Functional components are a great way to make code that can be used again and again and can be easily tested. They are easier to read and comprehend because they are simpler and lighter than class components.

They likewise have no interior state or lifecycle techniques, which makes them simpler to reason about.

import React from 'react';

function MyComponent(props) {
  return (
    <div>
      <h1>{props.title}</h1>
      <p>{props.description}</p>
    </div>
  );
}

export default MyComponent;

2. Use Prop Types to Validate Component Props.

React permits you to indicate the kinds of props that your parts acknowledge. This can assist you in early error detection and strengthen your code. The prop-types library can be used to specify the types of your props.

import React from 'react';
import PropTypes from 'prop-types';

function MyComponent(props) {
  return (
    <div>
      <h1>{props.title}</h1>
      <p>{props.description}</p>
    </div>
  );
}

MyComponent.propTypes = {
  title: PropTypes.string.isRequired,
  description: PropTypes.string.isRequired,
};

export default MyComponent;

3. How to Use Default Props to Provide Fallback Values.

Fallback values for your component props can be easily provided by using default props. This can make your code stronger to change and keep mistakes from happening.

import React from 'react';
import PropTypes from 'prop-types';

function MyComponent(props) {
  return (
    <div>
      <h1>{props.title}</h1>
      <p>{props.description}</p>
    </div>
  );
}

MyComponent.propTypes = {
  title: PropTypes.string.isRequired,
  description: PropTypes.string,
};

MyComponent.defaultProps = {
  description: 'No description available',
};

export default MyComponent;

4. Use CSS Modules to Encapsulate Component Styles.

CSS modules are an extraordinary method for embodying part styles and keeping them from spilling into different pieces of your code. They don't need any extra build steps and let you write CSS that is limited to a particular component.

import React from 'react';
import PropTypes from 'prop-types';
import styles from './MyComponent.module.css';

function MyComponent(props) {
  return (
    <div className={styles.container}>
      <h1 className={styles.title}>{props.title}</h1>
      <p className={styles.description}>{props.description}</p>
    </div>
  );
}

MyComponent.propTypes = {
  title: PropTypes.string.isRequired,
  description: PropTypes.string,
};

MyComponent.defaultProps = {
  description: 'No description available',
};

export default MyComponent;

5. Put Your Pieces Together in a Legitimate Order.

To make it easier to understand and maintain the code, it is essential to arrange your components in a logical hierarchy. This infers gathering related parts and making a sensible plan for your application.

This can make it more straightforward to add new highlights from here on out and assist with making your code simpler to peruse and keep up with.

6. Use memo or PureComponent to optimize performance

Rendering React components that contain a large number of props or state changes can be costly. To improve execution, you can utilize Unadulterated Parts which are higher-request parts that main re-render when their props or state have changed.

PureComponent is a class component that checks to see if it should update by superficially comparing its state and props. The component won't re-render if neither its state nor any of the props have changed.

Observe the illustration below;

import React, { PureComponent } from 'react';

class MyComponent extends PureComponent {
  render() {
    return (
      <div>
        <h1>{this.props.title}</h1>
        <p>{this.props.description}</p>
      </div>
    );
  }
}

export default MyComponent;

The memo is a higher-request part that works much the same way as PureComponent, yet it tends to be utilized with utilitarian parts rather than class parts.

Observe the illustration below;

import React, { memo } from 'react';

function MyComponent(props) {
  return (
    <div>
      <h1>{props.title}</h1>
      <p>{props.description}</p>
    </div>
  );
}

export default memo(MyComponent);

You can work on the presentation of your React parts and stay away from superfluous re-renders by using PureComponent or memo. Be that as it may, it means quite a bit to profile and test your application to check whether these enhancements are important, as utilizing PureComponent or memo probably won't be the most ideal choice in each situation.

Monitor the Utilization of your Components.

To close, observing your parts and their use is fundamental. This makes it simpler for other developers to locate your code and can help you save time by reducing the amount of time you spend resolving issues or responding to questions.

By providing comprehensive documentation for your application's components, you can improve its overall quality and usability. The production of high-quality React components is largely responsible for the application's success.
