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

Compare Source

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.release object, to reflect that 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.

Notable Changes
New "module-sync" exports condition

This release introduces a "module-sync" exports condition that's enabled when require(esm) is enabled, so packages can supply a synchronous ES module to the Node.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 support require(esm) in Node.js, and allows dual-package authors to opt into ESM-first only on newer versions of Node.js that supports require(esm) to avoid the dual-package hazard.

{
  "type": "module",
  "exports": {
    "node": {
      // On new version of Node.js, both require() and import get
      // the ESM version
      "module-sync": "./index.js",
      // On older version of Node.js, where "module-sync" and require(esm) are
      // not supported, use the CJS version to avoid dual-package hazard.
      // When package authors think it's time to drop support for older versions of
      // Node.js, they can remove the exports conditions and just use "main": "index.js".
      "default": "./dist/index.cjs"
    },
    // On any other environment, use the ESM version.
    "default": "./index.js"
  }
}

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):

{
  "type": "module",
  "exports": {
    // On new version of Node.js, both require() and import get the ESM version
    "module-sync": "./index.js",
    // On older version of Node.js, where "module-sync" and require(esm) are
    // not supported, use the CJS version to avoid dual-package hazard.
    // When package authors think it's time to drop support for older versions of
    // Node.js, they can remove the exports conditions and just use "main": "index.js".
    "default": "./dist/index.cjs"
  }
}

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 simplify their distributions by bumping the major version, dropping their CJS exports, and removing the module-sync exports condition (with only main or default targetting 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-sync and module and point them to the same ESM file. If the package already 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 module exports 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-sync conditions during the transition period, and can drop module-sync+module when they no longer need to 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' or import './directory'), so it would be breaking to implement a "module" condition without implementing the forbidden ESM resolution rules. For now, this just implements a new condition as semver-minor so it can be backported to older LTS.

node --run is now stable

This CLI flag runs a specified command from a package.json's "scripts" object.

For the following package.json:

{
  "scripts": {
    "test": "node --test-reporter junit --test ./test"
  }
}

You can run node --run test and that would start the test suite.

New API to retrieve execution Stack Trace

A new API getCallSite has been introduced to the util module. This API allows users to retrieve the stacktrace of the current execution. Example:

const util = require('node:util');

function exampleFunction() {
  const callSites = util.getCallSite();

  console.log('Call Sites:');
  callSites.forEach((callSite, index) => {
    console.log(`CallSite ${index + 1}:`);
    console.log(`Function Name: ${callSite.functionName}`);
    console.log(`Script Name: ${callSite.scriptName}`);
    console.log(`Line Number: ${callSite.lineNumber}`);
    console.log(`Column Number: ${callSite.column}`);
  });
  // CallSite 1:
  // Function Name: exampleFunction
  // Script Name: /home/example.js
  // Line Number: 5
  // Column Number: 26

  // CallSite 2:
  // Function Name: anotherFunction
  // Script Name: /home/example.js
  // Line Number: 22
  // Column Number: 3

  // ...
}

// A function to simulate another stack layer
function anotherFunction() {
  exampleFunction();
}

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 JS API for compile cache

This release adds a new API module.enableCompileCache() that can be used to enable on-disk code caching of all modules loaded after this API is called. Previously this could only be enabled by the NODE_COMPILE_CACHE environment variable, so it could only set by end-users. This API allows tooling and library authors to enable caching of their own code. This is a built-in alternative to the v8-compile-cache/v8-compile-cache-lib packages, but have better performance and supports ESM.

Thanks to Joyee Cheung for working on this.

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.

Thanks to Joyee Cheung for working on this.

Support for coverage thresholds

Node.js now supports requiring code coverage to meet a specific threshold before the process exits successfully. To use this feature, you need to enable the --experimental-test-coverage flag.

You can set thresholds for the following types of coverage:

  • Branch coverage: Use --test-coverage-branches=<threshold>
  • Function coverage: Use --test-coverage-functions=<threshold>
  • Line coverage: Use --test-coverage-lines=<threshold>

<threshold> should be an integer between 0 and 100. If an invalid value is provided, a TypeError will be thrown.

If the code coverage fails to meet the specified thresholds for any category, the process will exit with code 1.

For instance, to enforce a minimum of 80% line coverage and 60% branch coverage, you can run:

$ node --experimental-test-coverage --test-coverage-lines=80 --test-coverage-branches=60 example.js

Experimental transform types support

With the new flag --experimental-transform-types it is possible to enable the transformation of TypeScript-only syntax into JavaScript code.

This feature allows Node.js to support TypeScript syntax such as Enum and namespace.

Thanks to Marco Ippolito for making this work on #​54283.

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.

Performance Improvements to Buffer

Experimental TypeScript support via strip types

Node.js introduces the --experimental-strip-types flag for initial TypeScript support. This feature strips type annotations from .ts files, allowing them to run without transforming TypeScript-specific syntax. Current limitations include:

  • Supports only inline type annotations, not features like enums or namespaces.
  • Requires explicit file extensions in import and require statements.
  • Enforces the use of the type keyword for type imports to avoid runtime errors.
  • Disabled for TypeScript in node_modules by default.

Thanks Marco Ippolito for working on this.

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.

module: implement NODE_COMPILE_CACHE for automatic on-disk code caching

This 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.js from ~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.

v19.0.0

Compare Source

Below is a list of all new features, APIs, deprecations, and breaking changes. Read React 19 release post and React 19 upgrade guide for more information.

Note: To help make the upgrade to React 19 easier, we’ve published a react@18.3 release that is identical to 18.2 but adds warnings for deprecated APIs and other changes that are needed for React 19. We recommend upgrading to React 18.3.1 first to help identify any issues before upgrading to React 19.

New Features
React
  • Actions: startTransition can now accept async functions. Functions passed to startTransition are called “Actions”. A given Transition can include one or more Actions which update state in the background and update the UI with one commit. In addition to updating state, Actions can now perform side effects including async requests, and the Action will wait for the work to finish before finishing the Transition. This feature allows Transitions to include side effects like fetch() in the pending state, and provides support for error handling, and optimistic updates.
  • useActionState: is a new hook to order Actions inside of a Transition with access to the state of the action, and the pending state. It accepts a reducer that can call Actions, and the initial state used for first render. It also accepts an optional string that is used if the action is passed to a form action prop to support progressive enhancement in forms.
  • useOptimistic: is a new hook to update state while a Transition is in progress. It returns the state, and a set function that can be called inside a transition to “optimistically” update the state to expected final value immediately while the Transition completes in the background. When the transition finishes, the state is updated to the new value.
  • use: is a new API that allows reading resources in render. In React 19, use accepts a promise or Context. If provided a promise, use will suspend until a value is resolved. use can only be used in render but can be called conditionally.
  • ref as a prop: Refs can now be used as props, removing the need for forwardRef.
  • Suspense sibling pre-warming: When a component suspends, React will immediately commit the fallback of the nearest Suspense boundary, without waiting for the entire sibling tree to render. After the fallback commits, React will schedule another render for the suspended siblings to “pre-warm” lazy requests.
React DOM Client
  • <form> action prop: Form Actions allow you to manage forms automatically and integrate with useFormStatus. When a <form> action succeeds, React will automatically reset the form for uncontrolled components. The form can be reset manually with the new requestFormReset API.
  • <button> and <input> formAction prop: Actions can be passed to the formAction prop to configure form submission behavior. This allows using different Actions depending on the input.
  • useFormStatus: is a new hook that provides the status of the parent <form> action, as if the form was a Context provider. The hook returns the values: pending, data, method, and action.
  • Support for Document Metadata: We’ve added support for rendering document metadata tags in components natively. React will automatically hoist them into the <head> section of the document.
  • Support for Stylesheets: React 19 will ensure stylesheets are inserted into the <head> on the client before revealing the content of a Suspense boundary that depends on that stylesheet.
  • Support for async scripts: Async scripts can be rendered anywhere in the component tree and React will handle ordering and deduplication.
  • Support for preloading resources: React 19 ships with preinit, preload, prefetchDNS, and preconnect APIs to optimize initial page loads by moving discovery of additional resources like fonts out of stylesheet loading. They can also be used to prefetch resources used by an anticipated navigation.
React DOM Server
  • Added prerender and prerenderToNodeStream APIs for static site generation. They are designed to work with streaming environments like Node.js Streams and Web Streams. Unlike renderToString, they wait for data to load for HTML generation.
React Server Components
  • RSC features such as directives, server components, and server functions are now stable. This means libraries that ship with Server Components can now target React 19 as a peer dependency with a react-server export condition for use in frameworks that support the Full-stack React Architecture. The underlying APIs used to implement a React Server Components bundler or framework do not follow semver and may break between minors in React 19.x. See docs for how to support React Server Components.
Deprecations
  • Deprecated: element.ref access: React 19 supports ref as a prop, so we’re deprecating element.ref in favor of element.props.ref. Accessing will result in a warning.
  • react-test-renderer: In React 19, react-test-renderer logs a deprecation warning and has switched to concurrent rendering for web usage. We recommend migrating your tests to @​testing-library/react or @​testing-library/react-native
Breaking Changes

React 19 brings in a number of breaking changes, including the removals of long-deprecated APIs. We recommend first upgrading to 18.3.1, where we've added additional deprecation warnings. Check out the upgrade guide for more details and guidance on codemodding.

React
  • New JSX Transform is now required: We introduced a new JSX transform in 2020 to improve bundle size and use JSX without importing React. In React 19, we’re adding additional improvements like using ref as a prop and JSX speed improvements that require the new transform.
  • Errors in render are not re-thrown: Errors that are not caught by an Error Boundary are now reported to window.reportError. Errors that are caught by an Error Boundary are reported to console.error. We’ve introduced onUncaughtError and onCaughtError methods to createRoot and hydrateRoot to customize this error handling.
  • Removed: propTypes: Using propTypes will now be silently ignored. If required, we recommend migrating to TypeScript or another type-checking solution.
  • Removed: defaultProps for functions: ES6 default parameters can be used in place. Class components continue to support defaultProps since there is no ES6 alternative.
  • Removed: contextTypes and getChildContext: Legacy Context for class components has been removed in favor of the contextType API.
  • Removed: string refs: Any usage of string refs need to be migrated to ref callbacks.
  • Removed: Module pattern factories: A rarely used pattern that can be migrated to regular functions.
  • Removed: React.createFactory: Now that JSX is broadly supported, all createFactory usage can be migrated to JSX components.
  • Removed: react-test-renderer/shallow: This has been a re-export of react-shallow-renderer since React 18. If needed, you can continue to use the third-party package directly. We recommend using @​testing-library/react or @​testing-library/react-native instead.
React DOM
  • Removed: react-dom/test-utils: We’ve moved act from react-dom/test-utils to react. All other utilities have been removed.
  • Removed: ReactDOM.render, ReactDOM.hydrate: These have been removed in favor of the concurrent equivalents: ReactDOM.createRoot and ReactDOM.hydrateRoot.
  • Removed: unmountComponentAtNode: Removed in favor of root.unmount().
  • Removed: ReactDOM.findDOMNode: You can replace ReactDOM.findDOMNode with DOM Refs.
Notable Changes
React
  • <Context> as a provider: You can now render <Context> as a provider instead of <Context.Provider>.
  • Cleanup functions for refs: When the component unmounts, React will call the cleanup function returned from the ref callback.
  • useDeferredValue initial value argument: When provided, useDeferredValue will return the initial value for the initial render of a component, then schedule a re-render in the background with the deferredValue returned.
  • Support for Custom Elements: React 19 now passes all tests on Custom Elements Everywhere.
  • StrictMode changes: useMemo and useCallback will now reuse the memoized results from the first render, during the second render. Additionally, StrictMode will now double-invoke ref callback functions on initial mount.
  • UMD builds removed: To load React 19 with a script tag, we recommend using an ESM-based CDN such as esm.sh.
React DOM
  • Diffs for hydration errors: In the case of a mismatch, React 19 logs a single error with a diff of the mismatched content.
  • Compatibility with third-party scripts and extensions: React will now force a client re-render to fix up any mismatched content caused by elements inserted by third-party JS.
TypeScript Changes

The most common changes can be codemodded with npx types-react-codemod@latest preset-19 ./path-to-your-react-ts-files.

  • Removed deprecated TypeScript types:
    • ReactChild (replacement: React.ReactElement | number | string)
    • ReactFragment (replacement: Iterable<React.ReactNode>)
    • ReactNodeArray (replacement: ReadonlyArray<React.ReactNode>)
    • ReactText (replacement: number | string)
    • VoidFunctionComponent (replacement: FunctionComponent)
    • VFC (replacement: FC)
    • Moved to prop-types: Requireable, ValidationMap, Validator, WeakValidationMap
    • Moved to create-react-class: ClassicComponentClass, ClassicComponent, ClassicElement, ComponentSpec, Mixin, ReactChildren, ReactHTML, ReactSVG, SFCFactory
  • Disallow implicit return in refs: refs can now accept cleanup functions. When you return something else, we can’t tell if you intentionally returned something not meant to clean up or returned the wrong value. Implicit returns of anything but functions will now error.
  • Require initial argument to useRef: The initial argument is now required to match useState, createContext etc
  • Refs are mutable by default: Ref objects returned from useRef() are now always mutable instead of sometimes being immutable. This feature was too confusing for users and conflicted with legit cases where refs were managed by React and manually written to.
  • Strict ReactElement typing: The props of React elements now default to unknown instead of any if the element is typed as ReactElement
  • JSX namespace in TypeScript: The global JSX namespace is removed to improve interoperability with other libraries using JSX. Instead, the JSX namespace is available from the React package: import { JSX } from 'react'
  • Better useReducer typings: Most useReducer usage should not require explicit type arguments.
    For example, 
    -useReducer<React.Reducer<State, Action>>(reducer)
+useReducer(reducer)
    or 
    -useReducer<React.Reducer<State, Action>>(reducer)
+useReducer<State, Action>(reducer)
