How To Customize React Components with Props

Customizing React components with props is a fundamental aspect of building dynamic and reusable UIs. Props (short for properties) are used to pass data from a parent component to a child component. Here's a guide on how to customize React components using props:

Passing Props to Components:

1. Parent Component:

   Define a parent component and pass data to a child component using props.

                   
                       // ParentComponent.js
                       import React from 'react';
                       import ChildComponent from './ChildComponent';
                       
                       const ParentComponent = () => {
                         const name = 'John Doe';
                         const age = 30;
                       
                         return (
                           <div>
                             {/* Passing props to ChildComponent */}
                             <ChildComponent name={name} age={age} />
                           </div>
                         );
                       };                    
                       export default ParentComponent;                    
                   
               

2. Child Component:

   Access and utilize the props passed from the parent component.

                   
                       // ChildComponent.js
                       import React from 'react';
                       
                       const ChildComponent = (props) => {
                         // Accessing props in the ChildComponent
                         const { name, age } = props;
                       
                         return (
                           <div>
                             <h2>Name: {name}</h2>
                             <p>Age: {age}</p>
                           </div>
                         );
                       };                    
                       export default ChildComponent;                    
                   
               

Customizing Components with Props:

You can customize the behavior and appearance of components by passing different props:

1. Data Props:

   Pass data to components to display information dynamically.

2. Function Props:

   Pass functions as props to handle events or perform actions within a component.

3. Conditional Rendering:

   Use props to conditionally render content based on certain conditions.

4. Styling Props:

   Pass styling information to components via props to modify their appearance.

Example:

        
            // ParentComponent.js
            import React from 'react';
            import ChildComponent from './ChildComponent';
            
            const ParentComponent = () => {
              const buttonText = 'Click Me';
              const handleClick = () => {
                alert('Button clicked!');
              };
            
              return (
                <div>
                  {/* Passing props to ChildComponent */}
                  <ChildComponent buttonText={buttonText} handleClick={handleClick} />
                </div>
              );
            };            
            export default ParentComponent;            
        
    

        
            // ChildComponent.js
            import React from 'react';
            
            const ChildComponent = (props) => {
              const { buttonText, handleClick } = props;
            
              return (
                <div>
                  <button onClick={handleClick}>{buttonText}</button>
                </div>
              );
            };            
            export default ChildComponent;            
        
    

In this example, the ParentComponent passes buttonText and handleClick function as props to the ChildComponent, which uses these props to render a button and handle the click event.

Using props allows you to create reusable and customizable components in React by passing different data and functionalities based on the requirements of each instance of the component.
