Notable Changes
require(esm) is now enabled by default

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

This feature has been tested on v23.x and v22.x, and we are looking for user feedback from v20.x to make more final tweaks before fully stabilizing it. It now no longer emits a warning unless --trace-require-module is explicitly used. 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.

Module syntax detection is now enabled by default

Module syntax detection (the --experimental-detect-module flag) is now enabled by default. Use --no-experimental-detect-module to disable it if needed.

Syntax detection attempts to run ambiguous files as CommonJS, and if the module fails to parse as CommonJS due to ES module syntax, Node.js tries again and runs the file as an ES module. Ambiguous files are those with a .js or no extension, where the nearest parent package.json has no "type" field (either "type": "module" or "type": "commonjs"). Syntax detection should have no performance impact on CommonJS modules, but it incurs a slight performance penalty for ES modules; add "type": "module" to the nearest parent package.json file to eliminate the performance cost. A use case unlocked by this feature is the ability to use ES module syntax in extensionless scripts with no nearby package.json.

Thanks to Geoffrey Booth for making this work on #​53619.

Notable Changes
Experimental Network Inspection Support in Node.js

This update introduces the initial support for network inspection in Node.js. Currently, this is an experimental feature, so you need to enable it using the --experimental-network-inspection flag. With this feature enabled, you can inspect network activities occurring within a JavaScript application.

To use network inspection, start your Node.js application with the following command:

$ node --inspect-wait --experimental-network-inspection index.js

Please note that the network inspection capabilities are in active development. We are actively working on enhancing this feature and will continue to expand its functionality in future updates.

Exposes X509_V_FLAG_PARTIAL_CHAIN to tls.createSecureContext

This releases introduces a new option to the API tls.createSecureContext. From now on, tls.createSecureContext({ allowPartialTrustChain: true }) can be used to treat intermediate (non-self-signed) certificates in the trust CA certificate list as trusted.

New option for vm.createContext() to create a context with a freezable globalThis

Node.js implements a flavor of vm.createContext() and friends that creates a context without contextifying its global object when vm.constants.DONT_CONTEXTIFY is used. This is suitable when users want to freeze the context (impossible when the global is contextified i.e. has interceptors installed) or speed up the global access if they don't need the interceptor behavior.

module: support require()ing synchronous ESM graphs

This release adds require() support for synchronous ESM graphs under the flag --experimental-require-module.

If --experimental-require-module is enabled, and the ECMAScript module being loaded by require() meets the following requirements:

  • Explicitly marked as an ES module with a "type": "module" field in the closest package.json or a .mjs extension.
  • Fully synchronous (contains no top-level await).

require() will load the requested module as an ES Module, and return the module name space object. In this case it is similar to dynamic import() but is run synchronously and returns the name space object directly.

path: add matchesGlob method

Glob patterns can now be tested against individual paths via the path.matchesGlob(path, pattern) method.

stream: expose DuplexPair API

The function duplexPair returns an array with two items, each being a Duplex stream connected to the other side:

const [ sideA, sideB ] = duplexPair();

Whatever is written to one stream is made readable on the other. It provides behavior analogous to a network connection, where the data written by the client becomes readable by the server, and vice-versa.

process: add process.getBuiltinModule(id)

process.getBuiltinModule(id) provides a way to load built-in modules in a globally available function. ES Modules that need to support other environments can use it to conditionally load a Node.js built-in when it is run in Node.js, without having to deal with the resolution error that can be thrown by import in a non-Node.js environment or having to use dynamic import() which either turns the module into an asynchronous module, or turns a synchronous API into an asynchronous one.

if (globalThis.process?.getBuiltinModule) {
  // Run in Node.js, use the Node.js fs module.
  const fs = globalThis.process.getBuiltinModule('fs');
  // If `require()` is needed to load user-modules, use createRequire()
  const module = globalThis.process.getBuiltinModule('module');
  const require = module.createRequire(import.meta.url);
  const foo = require('foo');
}

If id specifies a built-in module available in the current Node.js process, process.getBuiltinModule(id) method returns the corresponding built-in module. If id does not correspond to any built-in module, undefined is returned.

process.getBuiltinModule(id) accepts built-in module IDs that are recognized by module.isBuiltin(id).

The references returned by process.getBuiltinModule(id) always point to the built-in module corresponding to id even if users modify require.cache so that require(id) returns something else.

doc: doc-only deprecate OpenSSL engine-based APIs

OpenSSL 3 deprecated support for custom engines with a recommendation to switch to its new provider model. The clientCertEngine option for https.request(), tls.createSecureContext(), and tls.createServer(); the privateKeyEngine and privateKeyIdentifier for tls.createSecureContext(); and crypto.setEngine() all depend on this functionality from OpenSSL.

test_runner: support test plans

It is now possible to count the number of assertions and subtests that are expected to run within a test. If the number of assertions and subtests that run does not match the expected count, the test will fail.

test('top level test', (t) => {
  t.plan(2);
  t.assert.ok('some relevant assertion here');
  t.subtest('subtest', () => {});
});

inspector: introduce the --inspect-wait flag

This release introduces the --inspect-wait flag, which allows debugger to wait for attachement. This flag is useful when you want to debug the code from the beginning. Unlike --inspect-brk, which breaks on the first line, this flag waits for debugger to be connected and then runs the code as soon as a session is established.

zlib: expose zlib.crc32()

This release exposes the crc32() function from zlib to user-land.

It computes a 32-bit Cyclic Redundancy Check checksum of data. If value is specified, it is used as the starting value of the checksum, otherwise, 0 is used as the starting value.

The CRC algorithm is designed to compute checksums and to detect error in data transmission. It's not suitable for cryptographic authentication.

const zlib = require('node:zlib');
const { Buffer } = require('node:buffer');

let crc = zlib.crc32('hello');  // 907060870
crc = zlib.crc32('world', crc);  // 4192936109

crc = zlib.crc32(Buffer.from('hello', 'utf16le'));  // 1427272415
crc = zlib.crc32(Buffer.from('world', 'utf16le'), crc);  // 4150509955

cli: allow running wasm in limited vmem with --disable-wasm-trap-handler

By default, Node.js enables trap-handler-based WebAssembly bound checks. As a result, V8 does not need to insert inline bound checks int the code compiled from WebAssembly which may speedup WebAssembly execution significantly, but this optimization requires allocating a big virtual memory cage (currently 10GB). If the Node.js process does not have access to a large enough virtual memory address space due to system configurations or hardware limitations, users won't be able to run any WebAssembly that involves allocation in this virtual memory cage and will see an out-of-memory error.

$ ulimit -v 5000000
$ node -p "new WebAssembly.Memory({ initial: 10, maximum: 100 });"
[eval]:1
new WebAssembly.Memory({ initial: 10, maximum: 100 });
^

RangeError: WebAssembly.Memory(): could not allocate memory
    at [eval]:1:1
    at runScriptInThisContext (node:internal/vm:209:10)
    at node:internal/process/execution:118:14
    at [eval]-wrapper:6:24
    at runScript (node:internal/process/execution:101:62)
    at evalScript (node:internal/process/execution:136:3)
    at node:internal/main/eval_string:49:3

--disable-wasm-trap-handler disables this optimization so that users can at least run WebAssembly (with a less optimial performance) when the virtual memory address space available to their Node.js process is lower than what the V8 WebAssembly memory cage needs.

v8: implement v8.queryObjects() for memory leak regression testing

This is similar to the queryObjects() console API provided by the Chromium DevTools console. It can be used to search for objects that have the matching constructor on its prototype chain in the heap after a full garbage collection, which can be useful for memory leak regression tests. To avoid surprising results, users should avoid using this API on constructors whose implementation they don't control, or on constructors that can be invoked by other parties in the application.

To avoid accidental leaks, this API does not return raw references to the objects found. By default, it returns the count of the objects found. If options.format is 'summary', it returns an array containing brief string representations for each object. The visibility provided in this API is similar to what the heap snapshot provides, while users can save the cost of serialization and parsing and directly filer the target objects during the search.

We have been using this API internally for the test suite, which has been more stable than any other leak regression testing strategies in the CI. With a public implementation we can now use the public API instead.

const { queryObjects } = require('node:v8');
class A { foo = 'bar'; }
console.log(queryObjects(A)); // 0
let a = new A();
console.log(queryObjects(A)); // 1
// [ "A { foo: 'bar' }" ]
console.log(queryObjects(A, { format: 'summary' }));

// Release the object.
a = null;
// Search again. queryObjects() includes a full garbage collection
// so a should disappear.
console.log(queryObjects(A)); // 0

class B extends A { bar = 'qux'; }
// The child class B's prototype has A's prototype on its prototype chain
// so the prototype object shows up too.
console.log(queryObjects(A, { format: 'summary' })); // [ A {}' ]
