On-thread hooks are back
This release introduces
module.registerHooks()for registering module loadercustomization hooks that are run for all modules loaded by
require(),importand functions returned by
createRequire()in the same thread, which makes themeasier for CJS monkey-patchers to migrate to.
This complements the
module.register()hooks - the new hooks fit betterinternally and cover all corners in the module graph; whereas
module.register()previously could not coverrequire()while it wason-thread, and still cannot cover
createRequire()after being movedoff-thread.
They are also run in the same thread as the modules being loaded and where the
hooks are registered, which means they are easier to debug (no more
console.log()getting lost) and do not have the many deadlock issues hauntingthe
module.register()hooks. The new API also takes functions directly so thatit's easier for intermediate loader packages to take user options from files
that the hooks can't be aware of, like many existing CJS monkey-patchers do.

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 containsnode_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-moduleas a workaround.With this feature enabled, Node.js will no longer throw
ERR_REQUIRE_ESMifrequire()is used to load a ES module. It can, however, throwERR_REQUIRE_ASYNC_MODULEif the ES module being loaded or its dependencies contain top-levelawait. When the ES module is loaded successfully byrequire(), the returned object will either be a ES module namespace object similar to what's returned byimport(), or what gets exported as"module.exports"in the ES module.Users can check
process.features.require_moduleto see whetherrequire(esm)is enabled in the current Node.js instance. For packages, the"module-sync"exports condition can be used as a way to detectrequire(esm)support in the current Node.js instance and allow bothrequire()andimportto load the same native ES module. See the documentation for more details about this feature.Contributed by Joyee Cheung in #55085

Notable Changes
This release marks the transition of Node.js 22.x into Long Term Support (LTS)
with the codename 'Jod'. The 22.x release line now moves into "Active LTS"
and will remain so until October 2025. After that time, it will move into
"Maintenance" until end of life in April 2027.
Other than updating metadata, such as the
process.releaseobject, to reflectthat the release is LTS, no further changes from Node.js 22.10.0 are included.
OpenSSL 3.x
Official binaries for Node.js 22.x currently include OpenSSL 3.0.x (more
specifically, the quictls OpenSSL fork).
OpenSSL 3.0.x is the currently designated long term support version that is
scheduled to be supported until 7th September 2026, which is within the expected
lifetime of Node.js 22.x. We are expecting upstream OpenSSL to announce a
successor long term support version prior to that date and since OpenSSL now
follows a semantic versioning-like versioning scheme we expect to be able to
update to the next long term supported version of OpenSSL during the lifetime of
Node.js 22.x.

New
"module-sync"exports conditionThis release introduces a
"module-sync"exports condition that's enabled whenrequire(esm)is enabled, so packages can supply a synchronous ES module to theNode.js module loader, no matter if it's being required or imported. This is
similar to the
"module"condition that bundlers have been using to supportrequire(esm)in Node.js, and allows dual-package authors to opt into ESM-firstonly on newer versions of Node.js that supports
require(esm)to avoid thedual-package hazard.
Or if the package is only meant to be run on Node.js and wants to fallback to
CJS on older versions that don't have
require(esm):For package authors: this only serves as a feature-detection mechanism for
packages that wish to support both CJS and ESM users during the period when some
active Node.js LTS versions support
require(esm)while some older ones don't.When all active Node.js LTS lines support
require(esm), packages can simplifytheir distributions by bumping the major version, dropping their CJS exports,
and removing the
module-syncexports condition (with onlymainordefaulttargetting the ESM exports). If the package needs to support both bundlers and
being run unbundled on Node.js during the transition period, use both
module-syncandmoduleand point them to the same ESM file. If the packagealready doesn't want to support older versions of Node.js that doesn't support
require(esm), don't use this export condition.For bundlers/tools: they should avoid implementing this stop-gap condition.
Most existing bundlers implement the de-facto bundler standard
moduleexports condition, and that should be enough to support users who want to bundle
ESM from CJS consumers. Users who want both bundlers and Node.js to recognize
the ESM exports can use both
module/module-syncconditions during thetransition period, and can drop
module-sync+modulewhen they no longer needto support older versions of Node.js. If tools do want to support this
condition, it's recommended to make the resolution rules in the graph pointed by
this condition match the Node.js native ESM rules to avoid divergence.
We ended up implementing a condition with a different name instead of reusing
"module", because existing code in the ecosystem using the"module"condition sometimes also expect the module resolution for these ESM files to
work in CJS style, which is supported by bundlers, but the native Node.js loader
has intentionally made ESM resolution different from CJS resolution (e.g.
forbidding
import './noext'orimport './directory'), so it would bebreaking to implement a
"module"condition without implementing the forbiddenESM resolution rules. For now, this just implements a new condition as
semver-minor so it can be backported to older LTS.

Disable V8 Maglev
We have seen several crashes/unexpected JS behaviors with maglev on v22
(which ships V8 v12.4). The bugs lie in the codegen so it would be difficult for
users to work around them or even figure out where the bugs are coming from.
Some bugs are fixed in the upstream while some others probably remain.
As v22 will get stuck with V8 v12.4 as LTS, it will be increasingly difficult to
backport patches for them even if the bugs are fixed. So disable it by default
on v22 to reduce the churn and troubles for users.

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

vm.createContext()and friends that creates a context without contextifying its globalobject 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.

Experimental transform types support

--experimental-transform-typesit is possible to enable thetransformation of TypeScript-only syntax into JavaScript code.
This feature allows Node.js to support TypeScript syntax such as
Enumandnamespace.Thanks to Marco Ippolito for making this work on #54283.
Module syntax detection is now enabled by default.
Module syntax detection (the
--experimental-detect-moduleflag) is nowenabled by default. Use
--no-experimental-detect-moduleto disable it ifneeded.
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
.jsor no extension, where the nearest parentpackage.jsonhas 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"tothe nearest parent
package.jsonfile 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.

module: implement
NODE_COMPILE_CACHEfor automatic on-disk code cachingThis patch implements automatic on-disk code caching that can be enabled
via an environment variable
NODE_COMPILE_CACHE=/path/to/cache/dir.When set, whenever Node.js compiles a CommonJS or a ECMAScript Module,
it will use on-disk V8 code cache
persisted in the specified directory
to speed up the compilation. This may slow down the first load of a
module graph, but subsequent loads of the same module graph may get
a significant speedup if the contents of the modules do not change.
Locally, this speeds up loading of
test/fixtures/snapshot/typescript.jsfrom ~130ms to ~80ms.
To clean up the generated code cache, simply remove the directory.
It will be recreated the next time the same directory is used for
NODE_COMPILE_CACHE.Compilation cache generated by one version of Node.js may not be used
by a different version of Node.js. Cache generated by different versions
of Node.js will be stored separately if the same directory is used
to persist the cache, so they can co-exist.
Caveat: currently when using this with V8 JavaScript code coverage, the
coverage being collected by V8 may be less precise in functions that are
deserialized from the code cache. It's recommended to turn this off when
running tests to generate precise coverage.

Automatically detect and run ESM syntax
The new flag
--experimental-detect-modulecan be used to automatically runES modules when their syntax can be detected. For “ambiguous” files, which are
.jsor extensionless files with nopackage.jsonwith atypefield, Node.jswill parse the file to detect ES module syntax; if found, it will run the file
as an ES module, otherwise it will run the file as a CommonJS module.
The same applies to string input via
--evalorSTDIN.We hope to make detection enabled by default in a future version of Node.js.
Detection increases startup time, so we encourage everyone — especially package
authors — to add a
typefield topackage.json, even for the default"type": "commonjs". The presence of atypefield, or explicit extensionssuch as
.mjsor.cjs, will opt out of detection.Contributed by Geoffrey Booth in #50096.
