how to resize image in react js with code examples 2

Resizing images is a common task in web development, especially in React JS projects. In this article, we will learn how to resize images in React JS through various methods.

Method 1: Using CSS styles

The simplest and most straightforward method to resize an image in React JS is by using CSS styles. Here's an example:

import React from "react";
import "./styles.css";

const App = () => {
  return (
    <div>
      <img
        src="https://images.unsplash.com/photo-1567130577111-5d238b71f8e2"
        alt="random"
        className="image"
      />
    </div>
  );
};

export default App;

.image {
  width: 500px;
  height: auto;
}

In this example, we're using the width property to set the image's width to 500 pixels. The height property is set to auto, which maintains the aspect ratio and scales the image's height accordingly.

Method 2: Using React Image Component

Another method to resize images in React JS is by using the react-image component. This approach has some benefits, such as lazy loading, loading indicators, and many more.

First, install the react-image package using the npm command line:

npm install react-image

Here's an example of how to use it:

import React from "react";
import Image from "react-image";

const App = () => {
  return (
    <div>
      <Image
        src="https://images.unsplash.com/photo-1567130577111-5d238b71f8e2"
        alt="random"
        width="500"
        height="auto"
      />
    </div>
  );
};

export default App;

In this example, we're using the Image component from react-image. We set the src and alt prop values as normal, but we can also add styling properties such as width and height.

Method 3: Using React Image Resizer

The last method on this list is using the react-image-resizer package. This library is designed explicitly to resize images, so it provides more options and flexibility.

First, install the react-image-resizer package using the npm command line:

npm install react-image-resizer

Here's an example of how to use it:

import React from "react";
import ImageResizer from "react-image-resizer";

const App = () => {
  return (
    <div>
      <ImageResizer
        src="https://images.unsplash.com/photo-1567130577111-5d238b71f8e2"
        alt="random"
        width={500}
        height={500}
        onClick={() => console.log("Image clicked")}
      />
    </div>
  );
};

export default App;

In this example, we're using the ImageResizer component from react-image-resizer. We set the src and alt prop values as normal, but we can also add styling properties such as width and height.

Conclusion

This article covered three methods for resizing images in React JS. The most straightforward way is by using CSS styles, but react-image and react-image-resizer provide more features and flexibility. Depending on the project's requirements, any of these methods could be the best option.

let me elaborate more on the previous topics.

Method 1: Using CSS styles

This method involves using CSS styles to set the width and height of the image. It's the simplest and most straightforward method. By setting the width, we tell the browser to make the image that size and adjust the height automatically to maintain the aspect ratio. Here's more about the properties we use:

• width: Sets the width of the image.
• height: Sets the height of the image. If set to auto, it maintains the aspect ratio.

This method is useful when we want to resize the image statically and don't need to manipulate it dynamically.

Method 2: Using React Image Component

The react-image component is a higher-level component that provides us more functionality such as lazy loading and various images related events. It's a useful package when we work with images.

It's essential to install the package using npm and import the Image component from it. Then we can use the component in the same way we use an img tag. The component accepts more props than the regular img tag; here are the props we used:

• src: URL for the image.
• alt: Alternate text for the image. It appears if the image fails to load.
• width: Sets the width of the image.
• height: Sets the height of the image. If set to auto, it maintains the aspect ratio.

Method 3: Using React Image Resizer

react-image-resizer is a package explicitly designed for resizing images. It provides more options and flexibility, such as adding a click event to the image.

Install the package using npm and import the ImageResizer component from it. Then use the component in the same way we use the other image components. Here are the props we used in the example:

• src: URL for the image.
• alt: Alternate text for the image. It appears if the image fails to load.
• width: Sets the width of the image.
• height: Sets the height of the image.
• onClick: The function that gets called when the image gets clicked.

The most beneficial feature of this package is adding an onClick prop, which provides more flexibility to set the click function for the image.

Conclusion

Resizing images is a fundamental task in web development. In React JS, we can use CSS styles, react-image, or react-image-resizer packages to resize images. Each method has its benefits and drawbacks, so it's up to the developer's requirement to choose the best option.

The react-image-resizer package is an excellent choice for full control over the image and provide useful props such as click events for images. However, when we need the basics, CSS styles, or the react-image package can solve the problem.
