Integrating imgix with Next.js

This guide provides instructions on how to integrate imgix with Next.js to handle image optimizations seamlessly. Next.js supports imgix as a custom loader which enables you to leverage imgix’s powerful image processing capabilities directly in your Next.js applications.

Prerequisites

Before integrating imgix with your Next.js project, ensure you have the following:

A Next.js project setup and running.
An imgix account and an active source configured.

Configuration

To configure imgix with Next.js, you need to modify the next.config.js file to include imgix as a custom image loader.

Define the imgix Loader

First, at your project root, create a loader file that specifies how images should be handled by nextjs:

loader.js

export default function imgixLoader = ({ src, width, quality }) => {
  const url = new URL(`https://your-subdomain.imgix.net${src}`)
  const params = url.searchParams
  params.set("auto", params.getAll("auto").join(",") || "format")
  params.set("fit", params.get("fit") || "max")
  params.set("w", params.get("w") || width.toString())
  return url.href
}

Update the Image Component Configuration

Next, in your next.config.js file, specify imgix as your custom image loader by updating the images section:

next.config.js

module.exports = {
  images: {
    remotePatterns: [
      {
        protocol: "https",
        hostname: "your-subdomain.imgix.net",
      },
    ],
    loader: "custom",
    loaderFile: "./loader.js",
  },
}

Use the Image Component

Now, you can use the Next.js <Image> component to load images through imgix. Here’s how to implement it in your project:

import Image from "next/image"
 
const MyImage = () => (
  <Image
    src="/path/to/image.jpg"
    alt="Description of the image"
    width={800}
    height={600}
    sizes="(max-width: 768px) 100vw, 50vw"
  />
)
 
export default MyImage
