I’m implementing the Next.js Image component in my Headless project. The CMS that I’m using is WordPress. And since the image is coming from an external website, I need to specify the domain on next.config.js, as the documentation specifies:

https://nextjs.org/docs/basic-features/image-optimization

const nextConfig = {
    image: {
        domains: ['https://example.com'],
    },
}

But in my next.config.js file I’ve already have this configuration:

const withStyles = require('@webdeb/next-styles');

module.exports = withStyles({
    sass: true,
    modules: true,
});

So my struggle is to combine this two on the config file.

Just for some context, without the image configuration, I have this error:

Error: Invalid src prop on next/image, hostname is not configured under images in your next.config.js

enter image description here

I’ve tried putting it together like the code bellow with the use of next-compose-plugins, but the error keeps showing:

const withStyles = require('@webdeb/next-styles');
const withPlugins = require('next-compose-plugins');

const nextConfig = {
    image: {
        domains: ['https://example.com'],
    },
}

module.exports = withPlugins([
    [withStyles({
        sass: true,
        modules: true,
    })]
], nextConfig);

Without the nextConfig at the end of the module.exports, the code works without a problem.

A detail on the URL that I need to pass is that it’s a subdomain and an homolog environment, but it doesn’t need credentials to be accessed. I don’t think it’s the issue, tho.

Since I’m new with the Next.js, I just can’t figure out how this configuration needs to work.

  1. Your config object should be passed to the last plugin call. So in your case it would look like the following:

    const withStyles = require('@webdeb/next-styles');
    
    module.exports = withStyles({
        sass: true,
        modules: true,
        images: {
            domains: ['https://example.com'],
        }
    });
    

    Also note that the correct entry for the next/image configuration is images and not image. Which is why it’s probably not working when you tried with next-compose-plugins, as everything else seems to be correct in that code snippet.

  2. For anyone whose above methods doesn’t work, please remove the https:// or http:// in next.config.js;

    module.exports = {
      reactStrictMode: true,
      images: {
        domains: ['https://your-domain.com'], //make it 'your-domain.com'
      },
    };
