@graphcms/react-image

Universal lazy-loading, auto-compressed images with React and GraphCMS.

Version Downloads/week Forks on GitHub minified + gzip size
DemoJoin us on SlackLogin to GraphCMS@GraphCMS

  • Resize large images to the size needed by your design.
  • Generate multiple smaller images to make sure devices download the optimal-sized one.
  • Automatically compress and optimize your image with the powerful Filestack API.
  • Efficiently lazy load images to speed initial page load and save bandwidth.
  • Use the "blur-up" technique or solid background color to show a preview of the image while it loads.
  • Hold the image position so your page doesn't jump while images load.

Quickstart

Here's an example using a static asset object.

import React from "react";
import Image from "@graphcms/react-image";

const IndexPage = () => {
  const asset = {
    handle: "uQrLj1QRWKJnlQv1sEmC",
    width: 800,
    height: 800
  }
  
  return <Image image={asset} maxWidth={800} />
}

Install

npm install @graphcms/react-image
