Notable Changes

require(esm) is now enabled by default

Support for loading native ES modules using require() had been available on v20.x and v22.x under the command line flag --experimental-require-module, and available by default on v23.x. In this release, it is now no longer behind a flag on v22.x.

This feature is still experimental, and we are looking for user feedback to make more final tweaks before fully stabilizing it. For this reason, on v22.x, when the Node.js instance encounters a native ES module in require() for the first time, it will emit an experimental warning unless require() comes from a path that contains node_modules. If there happens to be any regressions caused by this feature, users can report it to the Node.js issue tracker. Meanwhile this feature can also be disabled using --no-experimental-require-module as a workaround.

With this feature enabled, Node.js will no longer throw ERR_REQUIRE_ESM if require() is used to load a ES module. It can, however, throw ERR_REQUIRE_ASYNC_MODULE if the ES module being loaded or its dependencies contain top-level await. When the ES module is loaded successfully by require(), the returned object will either be a ES module namespace object similar to what's returned by import(), or what gets exported as "module.exports" in the ES module.

Users can check process.features.require_module to see whether require(esm) is enabled in the current Node.js instance. For packages, the "module-sync" exports condition can be used as a way to detect require(esm) support in the current Node.js instance and allow both require() and import to load the same native ES module. See the documentation for more details about this feature.

Added resizable ArrayBuffer support in Buffer

When a Buffer is created using a resizable ArrayBuffer, the Buffer length will now correctly change as the underlying ArrayBuffer size is changed.

const ab = new ArrayBuffer(10, { maxByteLength: 20 });
const buffer = Buffer.from(ab);
console.log(buffer.byteLength); 10
ab.resize(15);
console.log(buffer.byteLength); 15
ab.resize(5);
console.log(buffer.byteLength); 5
