react-cloudinary-image-lite v1.1.1

React Cloudinary Image Lite

This component is preparing WebP and AVIF image sets from assets hosted on Cloudinary, using density or resolution switching and a blurred preloading image placeholder.

This a simple no fuss React Image component to help you get up and running with responsive image sets from Cloudinary. For a more complex use case you can find other packages on NPM registry like Cloudinary React SDK @cloudinary/react.

Installation

npm i react-cloudinary-image-lite

Using the Image component

import { Image, Switching } from 'react-cloudinary-image-lite';

Density switching

The src prop is the Cloudinary asset ID composed by the folder name and the display name.

As width and height use the exact size of the original asset to be able to scale it proportionally.

Replace the cloudName prop with your product environment name from Cloudinary console. You can also find it in every asset link from each assets folder.

<Image
  src="blog/jedi-knight-3-v6_grl6fe.png"
  width={1823}
  height={1660}
  alt="jedi knight"
  switching={Switching.Density}
  quality={90}
  sizes="480px"
  cloudName="catalinworks"
  apiVersion="1"
/>

Resolution switching

1. By specifying the sizes prop like this:

<Image
  src="blog/rabbitmq_rctwjf.png"
  width={850}
  height={882}
  aspectRatio={0.9}
  switching={Switching.Resolution}
  alt="rabbitmq"
  priority
  quality={90}
  sizes="(min-width: 1536px) 500px, (min-width: 1280px) 400px, (min-width: 1024px) 400px, (min-width: 768px) 450px, 360px"
  cloudName="catalinworks"
  apiVersion="1"
/>

2. Or dynamically by using the breakpoints in your application and the image widths by breakpoint like this.

const imageWidths: { [key: string]: number } = {
  sm: 360,
  md: 450,
  lg: 400,
  xl: 400,
  '2xl': 500,
};

const breakpoints: { [key: string]: number } = {
  sm: 640,
  md: 768,
  lg: 1024,
  xl: 1280,
  '2xl': 1536,
};

And later in TSX:

<Image
  src="blog/rabbitmq_rctwjf.png"
  width={850}
  height={882}
  aspectRatio={0.9}
  alt="rabbitmq"
  switching={Switching.Resolution}
  quality={90}
  sizes={`(min-width: ${breakpoints['2xl']}px) ${imageWidths['2xl']}px, (min-width: ${breakpoints.xl}px) ${imageWidths.xl}px, (min-width: ${breakpoints.lg}px) ${imageWidths.lg}px, (min-width: ${breakpoints.md}px) ${imageWidths.md}px, ${imageWidths.sm}px`}
  priority
  cloudName="catalinworks"
  apiVersion="1"
/>
