Notable Changes

Deprecations and Removals

  • (SEMVER-MAJOR) fs: runtime deprecate string coercion in

    1
    fs.write

    ,

    1
    fs.writeFileSync

    (Livia Medeiros) #42607

  • (SEMVER-MAJOR) dns: remove

    1
    dns.lookup

    and

    1
    dnsPromises.lookup

    options type coercion (Antoine du Hamel) #41431

  • (SEMVER-MAJOR) process: runtime deprecate multipleResolves (Benjamin Gruenbaum) #41896
  • (SEMVER-MAJOR) stream: remove thenable support (Robert Nagy) #40773
  • (SEMVER-MAJOR) tls: move tls.parseCertString to end-of-life (Tobias Nießen) #41479

fetch (experimental)

An experimental fetch API is available on the global scope by default. The implementation is based upon undici, an HTTP/1.1 client written for Node.js by contributors to the project.


1
2
3
4
5
const res = await fetch('https://nodejs.org/api/documentation.json');
if (res.ok) {
  const data = await res.json();
  console.log(data);
}

Through this addition, the following globals are made available:

1
fetch

,

1
FormData

,

1
Headers

,

1
Request

,

1
Response

.

Disable this API with the

1
--no-experimental-fetch

command-line flag.

Contributed by Michaël Zasso in #41811.

HTTP Timeouts

1
server.headersTimeout

which limits the amount of time the parser will wait to receive the complete HTTP headers is now set to

1
60000

(60 seconds) by default.

1
server.requestTimeout

which sets the timeout value in milliseconds for receiving the entire request from the client is now set to

1
300000

(5 minutes) by default.

If these timeouts expire, the server responds with status 408 without forwarding the request to the request listener and then closes the connection.

Both timeouts must be set to a non-zero value to protect against potential Denial-of-Service attacks in case the server is deployed without a reverse proxy in front.

Contributed by Paolo Insogna in #41263.

Test Runner module (experimental)

The

1
node:test

module facilitates the creation of JavaScript tests that report results in TAP format. To access it:

1
import test from 'node:test';

This module is only available under the

1
node:

scheme.

The following is an example implementation of a parent test with two subtests:


1
2
3
4
5
6
7
8
9
test('top level test', async (t) => {
  await t.test('subtest 1', (t) => {
    assert.strictEqual(1, 1);
  });

  await t.test('subtest 2', (t) => {
    assert.strictEqual(2, 2);
  });
});

Toolchain and Compiler Upgrades

  • Prebuilt binaries for Linux are now built on Red Hat Enterprise Linux (RHEL) 8 and are compatible with Linux distributions based on glibc 2.28 or later, for example, Debian 10, RHEL 8, Ubuntu 20.04.
  • Prebuilt binaries for macOS now require macOS 10.15 or later.
  • For AIX the minimum supported architecture has been raised from Power 7 to Power 8.

Prebuilt binaries for 32-bit Windows will initially not be available due to issues building the V8 dependency in Node.js. We hope to restore 32-bit Windows binaries for Node.js 18 with a future V8 update.

Node.js does not support running on operating systems that are no longer supported by their vendor. For operating systems where their vendor has planned to end support earlier than April 2025, such as Windows 8.1 (January 2023) and Windows Server 2012 R2 (October 2023), support for Node.js 18 will end at the earlier date.

Full details about the supported toolchains and compilers are documented in the Node.js BUILDING.md file.

V8 10.1

The V8 engine is updated to version 10.1, which is part of Chromium 101. Compared to the version included in Node.js 17.9.0, the following new features are included:

The data format returned by the serialization API (

1
v8.serialize(value)

) has changed, and cannot be deserialized by earlier versions of Node.js. On the other hand, it is still possible to deserialize the previous format, as the API is backwards-compatible.

Contributed by Michaël Zasso in https://github.com/nodejs/node/pull/42657.

Web Streams API (experimental)

Node.js now exposes the experimental implementation of the Web Streams API on the global scope. This means the following APIs are now globally available:

  • 1
    ReadableStream

    ,

    1
    ReadableStreamDefaultReader

    ,

    1
    ReadableStreamBYOBReader
