Add support for NextJS

Is it possible to add support for NextJS?

You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

Hi @john--kane,

This is not something that we have control over. You are able to add node-loader to webpack bundler in order to load native bindings. I'm not sure how this is handled in NextJS, but I would assume it's similar to adding a "pg" module (for postgres).

You need to set-up webpack externals and make sure @gorules/zen-engine is installed in node_modules on the machine when you run it after building.

Try to find some examples with TypeORM and Postgres ("pg") or even this looks like a decent starting point: vercel/next.js#2790.

Hi @john--kane
I happen to run into the same issue today with integrating RuleEngine into NextJS (14.1.4).
I manage to get it working by

# add loader dependency
yarn add nextjs-node-loader --dev

# update next.config.mjs
/** @type {import('next').NextConfig} */
const nextConfig = {
  webpack: (config, { dev, isServer, webpack, nextRuntime }) => {
    config.module.rules.push({
      test: /\.node$/,
      use: [
        {
          loader: "nextjs-node-loader",
        },
      ],
    });
    return config;
  },
};

export default nextConfig;
