Notable Changes
--experimental-default-typeflag to flip module defaultsThe new flag
--experimental-default-typecan be used to flip the defaultmodule system used by Node.js. Input that is already explicitly defined as ES
modules or CommonJS, such as by a
package.json"type"field or.mjs/.cjsfile extension or the
--input-typeflag, is unaffected. What is currentlyimplicitly CommonJS would instead be interpreted as ES modules under
--experimental-default-type=module:String input provided via
--evalor STDIN, if--input-typeis unspecified.Files ending in
.jsor with no extension, if there is nopackage.jsonfilepresent in the same folder or any parent folder.
Files ending in
.jsor with no extension, if the nearest parentpackage.jsonfield lacks atypefield; unless the folder is inside anode_modulesfolder.In addition, extensionless files are interpreted as Wasm if
--experimental-wasm-modulesis passed and the file contains the "magic bytes"Wasm header.
Contributed by Geoffrey Booth in #49869.
Detect ESM syntax in ambiguous JavaScript
The new flag
--experimental-detect-modulecan be used to automatically run ESmodules 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.
New
flushoption in file system functionsWhen writing to files, it is possible that data is not immediately flushed to
permanent storage. This allows subsequent read operations to see stale data.
This PR adds a
'flush'option to thefs.writeFilefamily of functions whichforces the data to be flushed at the end of a successful write operation.

vm: fix V8 compilation cache support for vm.Script
Previously repeated compilation of the same source code using
vm.Scriptstopped hitting the V8 compilation cache after v16.x when support for
importModuleDynamicallywas added tovm.Script, resulting in a performanceregression that blocked users (in particular Jest users) from upgrading from
v16.x.
The recent fixes allow the compilation cache to be hit again
for
vm.Scriptwhen--experimental-vm-modulesis not used even in thepresence of the
importModuleDynamicallyoption, so that users affected by theperformance regression can now upgrade. Ongoing work is also being done to
enable compilation cache support for
vm.CompileFunction.Contributed by Joyee Cheung in #49950

built-in
.envfile supportStarting from Node.js v20.6.0, Node.js supports
.envfiles for configuring environment variables.Your configuration file should follow the INI file format, with each line containing a key-value pair for an environment variable.
To initialize your Node.js application with predefined configurations, use the following CLI command:
node --env-file=config.env index.js.For example, you can access the following environment variable using
process.env.PASSWORDwhen your application is initialized:In addition to environment variables, this change allows you to define your
NODE_OPTIONSdirectly in the.envfile, eliminating the need to include it in yourpackage.json.This feature was contributed by Yagiz Nizipli in #48890.
import.meta.resolveunflaggedIn ES modules,
import.meta.resolve(specifier)can be used to get an absolute URL string to whichspecifierresolves, similar torequire.resolvein CommonJS. This aligns Node.js with browsers and other server-side runtimes.This feature was contributed by Guy Bedford in #49028
New
node:moduleAPIregisterfor module customization hooks; newinitializehookThere is a new API
registeravailable onnode:moduleto specify a file that exports module customization hooks, and pass data to the hooks, and establish communication channels with them. The “define the file with the hooks” part was previously handled by a flag--experimental-loader, but when the hooks moved into a dedicated thread in 20.0.0 there was a need to provide a way to communicate between the main (application) thread and the hooks thread. This can now be done by callingregisterfrom the main thread and passing data, includingMessageChannelinstances.We encourage users to migrate to an approach that uses
--importwithregister, such as:Using
--importensures that the customization hooks are registered before any application code runs, even the entry point.This feature was contributed by Izaak Schroeder in #48842 and #48559
Module customization
loadhook can now support CommonJSAuthors of module customization hooks can how handle both ES module and CommonJS sources in the
loadhook. This works for CommonJS modules referenced via eitherimportorrequire, so long as the main entry point of the application is handled by the ES module loader (such as because the entry point is an ES module file, or if the--importflag is passed). This should simplify the customization of the Node.js module loading process, as package authors can customize more of Node.js without relying on deprecated APIs such asrequire.extensions.This feature was contributed by Antoine du Hamel in #47999
Node.js C++ addons now have experimental support for cppgc (Oilpan), a C++ garbage collection library in V8.
Now when Node.js starts up, it makes sure that there is a
v8::CppHeapattached to the V8 isolate. This enables users to allocate in thev8::CppHeapusing<cppgc/*>headers from V8, which are now also included into the Node.js headers available to addons. Note that since Node.js only bundles the cppgc library coming from V8, the ABI stability of cppgc is currently not guaranteed in semver-minor and -patch updates, but we do not expect the ABI to break often, as it has been stable and battle-tested in Chromium for years. We may consider including cppgc into the ABI stability guarantees when it gets enough adoption internally and externally.To help addon authors create JavaScript-to-C++ references of which V8's garbage collector can be aware, a helper function
node::SetCppgcReference(isolate, js_object, cppgc_object)has been added tonode.h. V8 may provide a native alternative in the future, which could then replace this Node.js-specific helper. In the mean time, users can use this API to avoid having to hard-code the layout of JavaScript wrapper objects. An example of how to create garbage-collected C++ objects in the unified heap and wrap it in a JavaScript object can be found in the Node.js addon tests.The existing
node::ObjectWraphelper would continue to work, while cppgc-based object management serves as an alternative with some advantages mentioned in the V8 blog post about Oilpan.This feature was contributed by Daryl Haresign and Joyee Cheung in #48660 and #45704.

We're excited to announce the release of Node.js 20! Highlights include the new Node.js Permission Model,
a synchronous
import.meta.resolve, a stable test_runner, updates of the V8 JavaScript engine to 11.3, Ada to 2.0,and more!
As a reminder, Node.js 20 will enter long-term support (LTS) in October, but until then, it will be the "Current" release for the next six months.
We encourage you to explore the new features and benefits offered by this latest release and evaluate their potential impact on your applications.
Notable Changes
Permission Model
Node.js now has an experimental feature called the Permission Model.
It allows developers to restrict access to specific resources during program execution, such as file system operations,
child process spawning, and worker thread creation.
The API exists behind a flag
--experimental-permissionwhich when enabled will restrict access to all available permissions.By using this feature, developers can prevent their applications from accessing or modifying sensitive data or running potentially harmful code.
More information about the Permission Model can be found in the Node.js documentation.
The Permission Model was a contribution by Rafael Gonzaga in #44004.
Custom ESM loader hooks run on dedicated thread
ESM hooks supplied via loaders (
--experimental-loader=foo.mjs) now run in a dedicated thread, isolated from the main thread.This provides a separate scope for loaders and ensures no cross-contamination between loaders and application code.
Synchronous
import.meta.resolve()In alignment with browser behavior, this function now returns synchronously.
Despite this, user loader
resolvehooks can still be defined as async functions (or as sync functions, if the author prefers).Even when there are async
resolvehooks loaded,import.meta.resolvewill still return synchronously for application code.Contributed by Anna Henningsen, Antoine du Hamel, Geoffrey Booth, Guy Bedford, Jacob Smith, and Michaël Zasso in #44710
V8 11.3
The V8 engine is updated to version 11.3, which is part of Chromium 113.
This version includes three new features to the JavaScript API:
The V8 update was a contribution by Michaël Zasso in #47251.
Stable Test Runner
The recent update to Node.js, version 20, includes an important change to the test_runner module. The module has been marked as stable after a recent update.
Previously, the test_runner module was experimental, but this change marks it as a stable module that is ready for production use.
Contributed by Colin Ihrig in #46983
Ada 2.0
Node.js v20 comes with the latest version of the URL parser, Ada. This update brings significant performance improvements
to URL parsing, including enhancements to the
url.domainToASCIIandurl.domainToUnicodefunctions innode:url.Ada 2.0 has been integrated into the Node.js codebase, ensuring that all parts of the application can benefit from the
improved performance. Additionally, Ada 2.0 features a significant performance boost over its predecessor, Ada 1.0.4,
while also eliminating the need for the ICU requirement for URL hostname parsing.
Contributed by Yagiz Nizipli and Daniel Lemire in #47339
Preparing single executable apps now requires injecting a Blob
Building a single executable app now requires injecting a blob prepared by
Node.js from a JSON config instead of injecting the raw JS file.
This opens up the possibility of embedding multiple co-existing resources into the SEA (Single Executable Apps).
Contributed by Joyee Cheung in #47125
Web Crypto API
Web Crypto API functions' arguments are now coerced and validated as per their WebIDL definitions like in other Web Crypto API implementations.
This further improves interoperability with other implementations of Web Crypto API.
This change was made by Filip Skokan in #46067.
Official support for ARM64 Windows
Node.js now includes binaries for ARM64 Windows, allowing for native execution on the platform.
The MSI, zip/7z packages, and executable are available from the Node.js download site along with all other platforms.
The CI system was updated and all changes are now fully tested on ARM64 Windows, to prevent regressions and ensure compatibility.
ARM64 Windows was upgraded to tier 2 support by Stefan Stojanovic in #47233.
WASI version must now be specified
When
new WASI()is called, the version option is now required and has no default value.Any code that relied on the default for the version will need to be updated to request a specific version.
This change was made by Michael Dawson in #47391.
Deprecations and Removals
url.parse()accepts URLs with ports that are not numbers. This behavior might result in host name spoofing with unexpected input.These URLs will throw an error in future versions of Node.js, as the WHATWG URL API does already.
Starting with Node.js 20, these URLS cause
url.parse()to emit a warning.Semver-Major Commits

Notable changes
Add support for externally shared js builtins
By default Node.js is built so that all dependencies are bundled into the Node.js binary itself. Some Node.js distributions prefer to manage dependencies externally. There are existing build options that allow dependencies with native code to be externalized. This commit adds additional options so that dependencies with JavaScript code (including WASM) can also be externalized. This addition does not affect binaries shipped by the Node.js project but will allow other distributions to externalize additional dependencies when needed.

--build-snapshotand--snapshot-bloboptions for creating and using user land snapshots.To generate a snapshot using snapshot.js as an entry point and write the snapshot blob to snapshot.blob:
To restore application state from snapshot.blob, with index.js as the entry point script for the deserialized application:
Users can also use the

Experimental ESM Loader Hooks API
Node.js ESM Loader hooks now support multiple custom loaders, and composition is
achieved via "chaining":
foo-loadercallsbar-loadercallsqux-loader(a custom loader must now signal a short circuit when intentionally not
calling the next). See the ESM docs for details.
Real-world use-cases are laid out for end-users with working examples in the
article Custom ESM loaders: Who, what, when, where, why, how.
