2023-11-30, Version 21.3.0 (Current), @RafaelGSS

Notable Changes

New `--disable-warning` flag

This version adds a new --disable-warning option that allows users to disable specific warnings either by code (i.e. DEP0025) or type (i.e. DeprecationWarning, ExperimentalWarning).

This option works alongside existing --warnings and --no-warnings.

For example, the following script will not emit DEP0025 require('node:sys') when executed with node --disable-warning=DEP0025:

import sys from 'node:sys';

Fast fs.writeFileSync with UTF-8 Strings

Enhanced writeFileSync functionality by implementing a highly efficient fast path primarily in C++ for UTF8-encoded string data. Additionally, optimized the appendFileSync method by leveraging the improved writeFileSync functionality. For simplicity and performance considerations, the current implementation supports only string data, as benchmark results raise concerns about the efficacy of using Buffer for this purpose. Future optimizations and expansions may be explored, but for now, the focus is on maximizing efficiency for string data operations.

Notable Changes

Automatically detect and run ESM syntax

The new flag --experimental-detect-module can be used to automatically run ES modules when their syntax can be detected. For “ambiguous” files, which are .js or extensionless files with no package.json with a type field, Node.js will 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 --eval or STDIN.

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 type field to package.json, even for the default "type": "commonjs". The presence of a type field, or explicit extensions such as .mjs or .cjs, will opt out of detection.

vm: fix V8 compilation cache support for vm.Script

Previously repeated compilation of the same source code using vm.Script stopped hitting the V8 compilation cache after v16.x when support for importModuleDynamically was added to vm.Script, resulting in a performance regression that blocked users (in particular Jest users) from upgrading from v16.x.

The recent fixes landed in v21.1.0 allow the compilation cache to be hit again for vm.Script when --experimental-vm-modules is not used even in the presence of the importModuleDynamically option, so that users affected by the performance regression can now upgrade. Ongoing work is also being done to enable compilation cache support for vm.CompileFunction.

2023-10-17, Version 21.0.0 (Current), @RafaelGSS and @targos

We're excited to announce the release of Node.js 21! Highlights include updates of the V8 JavaScript engine to 11.8, stable fetch and WebStreams, a new experimental flag to change the interpretation of ambiguous code from CommonJS to ES modules (--experimental-default-type), many updates to our test runner, and more!

Node.js 21 will replace Node.js 20 as our ‘Current’ release line when Node.js 20 enters long-term support (LTS) later this month. As per the release schedule, Node.js 21 will be ‘Current' release for the next 6 months, until April 2024.
