How to add Images in React.js

In this tutorial, we are going to learn about how to add images and background images in the react app with the help of examples.

Adding images to components

In react components, we can import images just like JavaScript modules where webpack includes that image file in a bundle and returns the final path of an image.

Example:

import React from 'react';
import car from './images/car.jpg'; // gives image path
function App(){
    return(
        <div>
             <img src={car} alt="this is car image" />        </div>
    )
}

export default App;

To reduce network requests and improve web performance importing images that are less than 10,000 bytes returns a data URI instead of a path.

Adding background images in CSS

.app{
    background-image: url(./images/car.jpg);
}

By adding the relative path of an image in CSS, webpack replaces them with a final path from the compiled bundle.
