nextjs-node-loader (No Longer Maintained)

Status: Deprecated

There's no need for it anymore. I've added an example in next 14 to demo including different native modules. Solution in NextJS 14 is to add a:

experimental: {
  serverComponentsExternalPackages: ['yournativemodule'],
}

For a dependency built with neon bindings, you might also need to configure externals:

/** @type {import('next').NextConfig} */
const nextConfig = {
  experimental: {
    serverComponentsExternalPackages: ['mynativemodule'],
  },
  /** @type {import('webpack').Configuration} */
  webpack: (config, context) => {
    if (context.isServer) {
      config.externals = [
        ...config.externals,
        {'mynativemodule': 'commonjs mynativemodule'},
      ]
    }
    return config;
  },
};

A huge thank you to everyone who contributed to this project! ❤️

nextjs-node-loader

This is a custom loader for Webpack that allows you to include native Node.js .node modules in your Next.js project. It simplifies the process of loading native modules by providing a standardized interface that works seamlessly with Next.js. This is a modified version of Node loader. More context on the why and example use of the loader in my blog post.

Getting Started

To begin, you'll need to install a nextjs-node-loader:

npm install nextjs-node-loader --save-dev

next.config.js

module.exports = {
  webpack: (config, { dev, isServer, webpack, nextRuntime }) => {
    config.module.rules.push({
      test: /\.node$/,
      use: [
        {
          loader: "nextjs-node-loader",
          options: {
            flags: os.constants.dlopen.RTLD_NOW,
            outputPath: config.output.path
          }
        },
      ],
    });
    return config;
  },
};

And use in e.g. your api route;

import module from "node-module";

export default function handler(req, res) {
  // ...
}

Options

Name	Type	Default	Description
flags	{Number}	undefined	Enables/Disables url/image-set functions handling
outputPath	{String}	webpack's outputPath	The root path of shared node libraries
includeWebpackPublicPath	{String}	false	If webpack_public_path should be included in a path for loading node module. For nextjs >13.2.5 should be false.
