An easy way to export static images in Next.js

Question

An easy way to export static images in Next.js

Whenever I try to export my nextjs app, an error message pops up stating that image export is not supported on static websites.

Error: The default image loader in Next.js cannot be used with next export. Possible solutions: - Use next start to run a server that includes the Image Optimization API. - Utilize a provider like Vercel that supports Image Optimization. - Configure a third-party loader in next.config.js. - Specify the loader prop for next/image.

Is there a way to make it work with image export?

Can I simply instruct it to render images statically without using online image loaders?

Answer №1

I developed a specialized npm module to enhance the functionality of the Next.js <Image/> component by optimizing images for static exports.

For more information, check out: https://www.npmjs.com/package/next-image-export-optimizer

This library modifies the behavior of the Next.js <Image/> component to automatically optimize images using sharp.js during the export process.

It includes a custom loader to generate a srcset for the <img/> element created by the Next.js <Image/> component. When building or exporting the project, the images in the public/images directory (or any specified folder) are optimized with sharp.js and transferred to the build directory.

To implement a custom image loader in your Next.js project, follow these steps:

1. Open your next.config.js file and include the following property in the export:

images: {
  loader: "custom"
}

2. Create a script named loader.js with the following content:

function customImageLoader({ src }) {
  return `/images/${src}`; // REPLACE WITH YOUR IMAGE DIRECTORY
}

module.exports = customImageLoader;

3. In each Image component, specify the loader prop manually:

const customImageLoader = require("PATH TO loader.js");

<Image loader={customImageLoader} />

If you're looking for a straightforward solution, one option is to simply opt-out of the next Image optimization feature. I personally found this to be a non-issue for my project. You can achieve this by including the following code in your next.config.js:

output: 'export',
images: {
    unoptimized: true,
}

On the other hand, you could explore using a custom loader that doesn't rely on a server runtime. However, I wouldn't necessarily recommend this approach for a few reasons:

It's generally more convenient to utilize a supported cloud Image loader like cloudinary.
You could also opt to use Next's native image optimizer by initiating it with next start.

But if you're set on using a custom preprocessor and loader, you have the option to try out https://www.npmjs.com/package/next-image-export-optimizer as suggested in a previous response.

Expanding on skara9's solution that didn't quite solve my issue, I stumbled upon a helpful discussion thread on github. The solution shared there worked perfectly for me by simply wrapping the NextJS image component. It's been working flawlessly ever since.

// components/Image.js
import NextImage from "next/image";

// opting out of image optimization, no action taken
const customLoader = ({ src }) => {
  return src
}

export default function Image(props) {
  return (
    <NextImage
      {...props}
      loader={customLoader}
    />
  );
}

Remember to update your imports and make changes to your next.config.js

import Image from '../components/Image.js'

If you're looking to export optimized images using next.js starting from 2023, check out this helpful resource!

To get started, follow these steps:

yarn add -D next-export-optimize-images

Then, integrate it as a next.js plugin:

const withExportImages = require(  "next-export-optimize-images");
module.exports = withExportImages({...baseConfig, output: "export"})

Next, adjust the build script in your project:

{
-  "build": "next build",
+  "build": "next build && next-export-optimize-images",
}

That's all you need to do to optimize image exports!
