What are some advantages of Component Driven Development ?

Component Driven Development (CDD) is a fundamental feature in ReactJS, playing a significant role in our preference for building applications with the React library. The essence of CDD lies in the segmentation of large file content into smaller, reusable parts that find application across multiple areas.

These are some advantages of the Component Driven Development in React:

• Reusability: In Component-driven Development, the ability to easily reuse components across various modules optimizes development efforts and cost allocation, contributing to efficient application scalability.
• Repetition: Given that applications often comprise repetitive components, embracing repetition in component development enables developers to manage and scale their code effectively. This repetition fosters user familiarity with a symmetric design, aiding in informed decision-making.
• Scalability: Component Driven Development extends the advantages of modular architecture to the frontend. This approach facilitates seamless integration of additional components for new features as a React application scales, avoiding the need for a complete codebase overhaul.
• Simpler Maintenance: Component Driven Development models in software engineering prevent unwieldy situations by decomposing frontend files into smaller, easily manageable components. This streamlined structure simplifies maintenance, making upgrades or modifications straightforward tasks.
• Faster Development: Component Driven Development significantly accelerates the development process and enhances the relationship with the codebase. Leveraging accessible shared libraries, development teams can efficiently utilize pre-built components, reducing the necessity to build solutions from scratch.

Prerequisites:

• Node JS or NPM
• React JS

Steps to create React Application And Installing Module:

Step 1: Create a React application using the following command:

npx create-react-app example

Step 2: After creating your project folder i.e. example, move to it using the following command:

cd example

Step 3: Create folder components inside src folder of react project directory and inside the components folder create files Button.jsx, Card.jsx and List.jsx.

Project Structure:

folder structure

The updated dependencies in package.json file will look like:

"dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4",
}

Example: Write down the following code in App.js, and components folder files.

Javascript

//App.jsx

import React from 'react'
import Card from './components/Card'

const App = () => {
    return (
        <div style={{
            display: 'flex',
            flexDirection: 'column',
            alignItems: 'center',
            justifyContent: 'space-around',
            marginTop: '20px',
            height: '100vh',
            width: '100vw',
        }}>
            <div>Components based design</div>
            <div style={{
                display: 'flex',
                flexDirection: 'row',
                justifyContent: 'space-around',
                width: '100%',
                height: '100%',
                marginTop: '20px',
            }}>
                <Card />
                <Card />
                <Card />
                <Card />
            </div>
        </div>
    )
}

export default App

Javascript

//Button.jsx

import React from 'react'

const Button = () => {
    return (
        <div
            style={{
                backgroundColor: 'green',
                color: 'white',
                padding: '10px',
                borderRadius: '5px',
                cursor: 'pointer',
                margin: '10px'
            }}
            onClick={() => alert('Button clicked')}
        >Button</div>
    )
}

export default Button

Javascript

//Card.jsx

import React from 'react'
import List from './List'
import Button from './Button'

const Card = () => {
  return (
    <div style={{
      height: '200px',
      width: '200px',
      backgroundColor: '#f4f4f4',
      borderRadius: '5px',
      margin: '10px',
      display: 'flex',
      flexDirection: 'column',
      justifyContent: 'space-between',
      alignItems: 'center',
import React from 'react'
import List from './List'
import Button from './Button'

const Card = () => {
    return (
        <div style={{
            height: '200px',
            width: '200px',
            backgroundColor: '#f4f4f4',
            borderRadius: '5px',
            margin: '10px',
            display: 'flex',
            flexDirection: 'column',
            justifyContent: 'space-between',
            alignItems: 'center',
            boxShadow: '0px 0px 5px #ccc'

        }}>
            <List />
            <Button></Button>
        </div>
    )
}

export default Card
      boxShadow: '0px 0px 5px #ccc'

    }}>
      <List />
      <Button></Button>
    </div>
  )
}

export default Card

//List.jsx

import React from 'react'

const List = () => {
    return (
        <div>List item</div>
    )
}

export default List
