Module parse failed: /canvas/build/Release/canvas.node Unexpected character '�'

[playground]

When build with webpack, it throws these errors.
I'm using fabric.js 1.7.3 which has a dependencies on canvas 1.6.2

This is because canvas.node is a natively compiled module, and isn't a javascript file. I don't see how this will be able to work with webpack...

Are you intending to run the resulting bundle with Node.js or in the browser?

[playground]

I intend to run the bundle with Node.js. @LinusU do you have a way to make it work?

[zbjornson]

@playground I hadn't heard of using webpack for node.js until now, but... I think the only way this could work is if you use the externals option to stop webpack from bundling canvas since it cannot bundle native code. There's also this plugin for webpack: https://github.com/webpack-contrib/node-loader

For me providing the canvas as an external empty object worked:

externals : { canvas: {} }

In my case I am using webpack with karma to run unit test. Since canvas is not part of any test mocking it with an empty object did the trick.

I have this issue on gatsby SSR app, below code is not the correct way and will damage you canvas

externals : { canvas: {} }

I fixed it in this way with next 14.0.4

import './src/env.mjs';
/** @type {import('next').NextConfig} */

const nextConfig = {
  webpack: (
    config,
    { buildId, dev, isServer, defaultLoaders, nextRuntime, webpack }
  ) => {
    config.externals.push({ canvas: 'commonjs canvas' })
    return config
  },
};

export default nextConfig;

I've updated next config file but error still persist

I followed the steps here.
I found this blog post. I also added use client to parts of my Next.js application to get the bug to go away.

My next.config.js file looks something like this as suggested in the article.

/** @type {import('next').NextConfig} */
module.exports = {
	webpack: (config) => {
		config.externals.push({
			'utf-8-validate': 'commonjs utf-8-validate',
			bufferutil: 'commonjs bufferutil',
			canvas: 'commonjs canvas',
		});
		// config.infrastructureLogging = { debug: /PackFileCache/ };
		return config;
	},
};

add in nuxt.config.js

build: {
extend(config) {
config.externals = {
'canvas': 'commonjs canvas'
};
}
}
