Developing ES6 modules in C++ using Node.js

Here is a previous example showcasing how to create a Node.js addon in C++:
https://nodejs.org/api/addons.html

You can use node-gyp to build it into a common JS module, which works well with the 'require' function. However, when trying to import the compiled module in a .mjs file, it doesn't work.

This command works: node test.js

// test.js
var m = require("./build/Release/addon");
console.log(m.hello());

This command does not work:

node --experimental-modules test.mjs

// test.mjs
import * as m from "./build/Release/addon";
console.log(m.hello());

The error message displayed is:

Error [ERR_MODULE_NOT_FOUND]: Cannot find module

The C++ addon example provided is tailored for the old version of Node.js using common JS. Are there any examples available for creating a C++ addon that can be built into an ES6 module for importing into .mjs files?

Answer №1

It is important to note that Node does not currently support loading native modules using the import syntax.

If you are working with an ESM file, you will need to follow this pattern:

import { createRequire } from 'module';
const require = createRequire(import.meta.url);

const m = require('./build/Release/addon');
console.log(m.hello());
