Node.js v15 arrived and became the Current version!

Some features delivered in Node.js 15:

AbortController: AbortController is a global utility class used to signal cancelation in selected Promise-based APIs, based on the AbortController Web API.

N-API Version 7: N-API 7 brings additional methods for working with ArrayBuffers.

npm 7: npm 7 comes with many new features like npm workspaces and a new package-lock.json format. npm 7 includes yarn.lock file support. Peer dependencies are now installed by default.

Throw on unhandled rejections: As of Node.js 15, the default mode for unhandledRejection is changed to throw (from warn). In throw mode, if an unhandledRejection hook is not set, the unhandledRejection is raised as an uncaught exception. Users that have an unhandledRejection hook should see no change in behavior, and it’s still possible to switch modes using the --unhandled-rejections=mode process flag.

QUIC (experimental): QUIC is a UDP-based, underlying transport protocol for HTTP/3. QUIC features inbuilt security with TLS 1.3, flow control, error correction, connection migration, and multiplexing. QUIC can be enabled by compiling Node.js with the --experimental-quic configuration flag. The Node.js QUIC implementation is exposed by the core net module.

V8 8.6: The V8 JavaScript engine has been updated to V8 8.6 (V8 8.4 is the latest available in Node.js 14). Along with performance tweaks and improvements the V8 update also brings the following language features:

  • Promise.any() (from V8 8.5)
  • AggregateError (from V8 8.5)
  • String.prototype.replaceAll() (from V8 8.5)
  • Logical assignment operators &&=, ||=, and ??= (from V8 8.5)

Node.js LTS v15 Changelogs

Changelog for Node v15.2.0 (Current)

  • events: getEventListeners static
  • fs: support abortsignal in writeFile, add support for AbortSignal in readFile
  • stream: fix thrown object reference

Changelog for Node v15.1.0 (Current)

Diagnostics channel (experimental module): diagnostics_channel is a new experimental module that provides an API to create named channels to report arbitrary message data for diagnostics purposes. With diagnostics_channel, Node.js core and module authors can publish contextual data about what they are doing at a given time. This could be the hostname and query string of a mysql query, for example.

New child process 'spawn' event: Instances of ChildProcess now emit a new 'spawn' event once the child process has spawned successfully. If emitted, the 'spawn' event comes before all other events and before any data is received via stdout or stderr. The 'spawn' event will fire regardless of whether an error occurs within the spawned process. For example, if bash some-command spawns successfully, the 'spawn' event will fire, though bash may fail to spawn some-command. This caveat also applies when using { shell: true }.

Set the local address for DNS resolution: It is now possible to set the local IP address used by a Resolver instance to send its requests. This allows programs to specify outbound interfaces when used on multi-homed systems. The resolver will use the v4 local address when making requests to IPv4 DNS servers, and the v6 local address when making requests to IPv6 DNS servers.

Control V8 coverage at runtime: The v8 module includes two new methods to control the V8 coverage started by the NODE_V8_COVERAGE environment variable. With v8.takeCoverage(), it is possible to write a coverage report to disk on demand. This can be done multiple times during the lifetime of the process, and the execution counter will be reset on each call. When the process is about to exit, one last coverage will still be written to disk, unless v8.stopCoverage() was invoked before. The v8.stopCoverage() method allows to stop the coverage collection, so that V8 can release the execution counters and optimize code.

Analyze Worker's event loop utilization: Worker instances now have a performance property, with a single eventLoopUtilization method that can be used to gather information about the worker's event loop utilization between the 'online' and 'exit' events. The method works the same way as perf_hooks eventLoopUtilization().

Take a V8 heap snapshot just before running out of memory (experimental):
With the new --heapsnapshot-near-heap-limit=max_count experimental command line flag, it is now possible to automatically generate a heap snapshot when the V8 heap usage is approaching the heap limit. count should be a non-negative integer (in which case Node.js will write no more than max_count snapshots to disk). When generating snapshots, garbage collection may be triggered and bring the heap usage down, therefore multiple snapshots may be written to disk before the Node.js instance finally runs out of memory. These heap snapshots can be compared to determine what objects are being allocated during the time consecutive snapshots are taken.

Changelog for Node v15.0.1 (Current)

  • crypto: fix regression on randomFillSync
  • deps: upgrade npm to 7.0.3

Node.js v14 Highlights

The highlights in this release include improved diagnostics, an upgrade of V8, an experimental Async Local Storage API, hardening of the streams APIs, removal of the Experimental Modules warning, and the removal of some long deprecated APIs.

Node.js 14 was promoted to Long-term Support (LTS) in October 2020. As a reminder — both Node.js 12 and Node.js 10 will remain in long-term support until April 2022 and April 2021 respectively.

    • (SEMVER-MAJOR) fs: deprecate closing FileHandle on garbage collection
    • (SEMVER-MAJOR) http: move OutboundMessage.prototype.flush to EOL
    • (SEMVER-MAJOR) lib: move GLOBAL and root aliases to EOL
    • (SEMVER-MAJOR) os: move tmpDir() to EOL
    • (SEMVER-MAJOR) src: remove deprecated wasm type check
    • (SEMVER-MAJOR) stream: move _writableState.buffer to EOL
    • (SEMVER-MINOR) doc: deprecate process.mainModule
    • (SEMVER-MINOR) doc: deprecate process.umask() with no arguments
  • ECMAScript Modules - Experimental Warning Removal

In Node.js 13 we removed the need to include the --experimental-modules flag, but when running EcmaScript Modules in Node.js, this would still result in a warning ExperimentalWarning: The ESM module loader is experimental.

As of Node.js 14 there is no longer this warning when using ESM in Node.js. However, the ESM implementation in Node.js remains experimental. As per our stability index: “The feature is not subject to Semantic Versioning rules. Non-backward compatible changes or removal may occur in any future release.” Users should be cautious when using the feature in production environments.

The ESM implementation in Node.js is still experimental but we do believe that we are getting very close to being able to call ESM in Node.js “stable”. Removing the warning is a huge step in that direction.

  • New V8 ArrayBuffer API src: migrate to new V8 ArrayBuffer API. Multiple ArrayBuffers pointing to the same base address are no longer allowed by V8. This may impact native addons.

  • Toolchain and Compiler Upgrades

    • (SEMVER-MAJOR) build: update macos deployment target to 10.13 for 14.x
    • (SEMVER-MAJOR) doc: update cross compiler machine for Linux armv7
    • (SEMVER-MAJOR) doc: update Centos/RHEL releases use devtoolset-8
    • (SEMVER-MAJOR) doc: remove SmartOS from official binaries
    • (SEMVER-MAJOR) win: block running on EOL Windows versions

It is expected that there will be an ABI mismatch on ARM between the Node.js binary and native addons. Native addons are only broken if they interact with std::shared_ptr. This is expected to be fixed in a later version of Node.js 14.

  • Update to V8 8.1 (SEMVER-MAJOR) deps: update V8 to 8.1.307.20

    • Enables Optional Chaining by default
    • Enables Nullish Coalescing by default
    • Enables Intl.DisplayNames by default
    • Enables calendar and numberingSystem options for Intl.DateTimeFormat by default
  • Other Notable Changes:

    • cli, report: move --report-on-fatalerror to stable
    • deps: upgrade to libuv 1.37.0
    • fs: add fs/promises alias module
