Adds an experimental node:vfs builtin (gated behind --experimental-vfs) with VirtualFileSystem, VirtualProvider, MemoryProvider, and RealFSProvider. No integration with node:fs, the module loader, or SEA those are intended to land in follow-up PRs.

Extracted from: #61478

Approximate line counts: code ~4k / docs ~1k / tests ~5k — total ~10k lines, with tests being the largest share.

No integration with node:fs

The docs in this PR claim that you can call myVfs.mount('/virtual') and subsequently regular node:fs operations which read from paths beginning with /virtual will read from the VFS. That sounds like integration to me. Are the docs wrong, or am I misunderstanding what "no integration" means?

mcollina added a commit to mcollina/node that referenced this pull request May 29, 2026
Add mount/unmount lifecycle on `VirtualFileSystem`, a handler registry
that fs.js and fs/promises.js consult via `vfsState.handlers`, and a
router that maps absolute paths to the VFS that owns them. When a VFS
is mounted, the public `fs.*` and `fs/promises` APIs (including
streams, `fs.watch`, and `opendir`) dispatch to the provider for paths
under the mount point, and fall through to the real filesystem
otherwise. Includes per-method dispatch tests, error-path coverage,
multi-mount routing tests, and router unit tests.

littledivy pushed a commit to denoland/deno that referenced this pull request Jun 2, 2026
The original draft was ported from @platformatic/vfs (extracted from the
still-open nodejs/node#61478). Node has since merged the experimental
subsystem in nodejs/node#63115, with a slightly different public surface.
Rebase the polyfill on the merged source so the API matches what landed
in Node behind --experimental-vfs:

- Stats objects are now real fs.Stats / BigIntStats instances (no more
  custom VirtualStats shape).
- Adds RealFSProvider, VirtualDir, plus the polling watcher classes
  (VFSWatcher / VFSStatWatcher / VFSWatchAsyncIterable).
- Adds rmSync/rm, truncateSync, linkSync, chmodSync, chownSync,
  utimesSync, lutimesSync, mkdtempSync, opendirSync, openAsBlob, the
  matching callback wrappers, and the matching promises API.
- Drops the Deno-specific extensions from the previous draft
  (mount/unmount/mounted/shouldHandle, virtualCwd/chdir, vfs-mount and
  vfs-unmount process events, internalModuleStat); they have no
  counterpart in the merged Node API and the module-loader integration
  is intentionally left for a follow-up upstream.

### v25.9.0

### Notable Changes

#### Test runner module mocking improvements

`MockModuleOptions.defaultExport` and `MockModuleOptions.namedExports` have been
consolidated into a single option `MockModuleOptions.exports` to align with user
expectations and other test runners.

A `default` property on `MockModuleOptions.exports`  represents the default
export, and own enumerable properties are treated as named exports.

An automated migration is available to update user code:
<https://github.com/nodejs/userland-migrations/tree/main/recipes/mock-module-exports>

### v26.0.0

We're excited to announce the release of Node.js 26! Highlights include the Temporal API enabled by default,
updates to the V8 JavaScript engine to 14.6, Undici to 8.0, and several important deprecations and removals
as we continue to modernize the platform.

As a reminder, Node.js 26 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

#### Temporal API

The Temporal API is now enabled by default in Node.js 26. Temporal is a modern date/time API for JavaScript
that provides a more robust and feature-rich alternative to the legacy `Date` object.

Contributed by Richard Lau in [#61806](nodejs/node#61806).

#### V8 14.6

The V8 engine is updated to version 14.6.202.33, which is part of Chromium 134.

This version also includes:

* Upsert (<https://github.com/tc39/proposal-upsert>): `[Weak]Map.prototype.getOrInsert()`, `[Weak]Map.prototype.getOrInsertComputed()`
* Iterator sequencing (<https://github.com/tc39/proposal-iterator-sequencing>): `Iterator.concat()`

Contributed by Michaël Zasso in [#61898](nodejs/node#61898).

#### Undici 8

Undici has been updated to version 8.0.2, bringing new features and improvements to Node.js's HTTP client implementation.

#### Deprecations and Removals

* \[[`dff46c07c3`](nodejs/node@dff46c07c3)] - **(SEMVER-MAJOR)** **crypto**: move DEP0182 to End-of-Life (Tobias Nießen) [#61084](nodejs/node#61084)

`http.Server.prototype.writeHeader()` is now fully removed. Use `http.Server.prototype.write… (truncated)

### v26.1.0

### Notable Changes

#### Experimental `node:ffi` module

Node.js now includes an experimental `node:ffi` module for loading dynamic
libraries and calling native symbols from JavaScript.

The API is gated behind the `--experimental-ffi` flag and, when the Permission
Model is enabled, requires `--allow-ffi`.

This API is inherently unsafe. Invalid pointers, incorrect signatures, or accessing memory
after it has been freed can crash the process or corrupt memory.

Contributed by Paolo Insogna in [#62072](nodejs/node#62072).

### v26.3.0

### Notable Changes

#### Potential changes to macOS Universal Binary availability

With Apple and its ecosystem progressively dropping support for Intel-based
architectures, it has become apparent that the Node.js project may not be able
to maintain the universal binaries we currently distribute for the full lifetime
of Node.js 26. This change serves to communicate that risk. At present, our
intention remains to continue shipping universal binaries supporting both Apple
Silicon and Intel-based Macs for as long as practical.

<summary>node: `24.19.0` → `26.7.0` (nodejs/node)</summary>

### v26.0.0

We're excited to announce the release of Node.js 26! Highlights include the Temporal API enabled by default,
updates to the V8 JavaScript engine to 14.6, Undici to 8.0, and several important deprecations and removals
as we continue to modernize the platform.

As a reminder, Node.js 26 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

#### Temporal API

The Temporal API is now enabled by default in Node.js 26. Temporal is a modern date/time API for JavaScript
that provides a more robust and feature-rich alternative to the legacy `Date` object.

Contributed by Richard Lau in [#61806](nodejs/node#61806).

#### V8 14.6

The V8 engine is updated to version 14.6.202.33, which is part of Chromium 134.

This version also includes:

* Upsert (<https://github.com/tc39/proposal-upsert>): `[Weak]Map.prototype.getOrInsert()`, `[Weak]Map.prototype.getOrInsertComputed()`
* Iterator sequencing (<https://github.com/tc39/proposal-iterator-sequencing>): `Iterator.concat()`

Contributed by Michaël Zasso in [#61898](nodejs/node#61898).

#### Undici 8

Undici has been updated to version 8.0.2, bringing new features and improvements to Node.js's HTTP client implementation.

#### Deprecations and Removals

* \[[`dff46c07c3`](nodejs/node@dff46c07c3)] - **(SEMVER-MAJOR)** **crypto**: move DEP0182 to End-of-Life (Tobias Nießen) [#61084](nodejs/node#61084)

`http.Server.prototype.writeHeader()` is now fully removed. Use `http.Server.prototype.write… (truncated)

### v26.1.0

### Notable Changes

#### Experimental `node:ffi` module

Node.js now includes an experimental `node:ffi` module for loading dynamic
libraries and calling native symbols from JavaScript.

The API is gated behind the `--experimental-ffi` flag and, when the Permission
Model is enabled, requires `--allow-ffi`.

This API is inherently unsafe. Invalid pointers, incorrect signatures, or accessing memory
after it has been freed can crash the process or corrupt memory.

### v26.3.0

### Notable Changes

#### Potential changes to macOS Universal Binary availability

With Apple and its ecosystem progressively dropping support for Intel-based
architectures, it has become apparent that the Node.js project may not be able
to maintain the universal binaries we currently distribute for the full lifetime
of Node.js 26. This change serves to communicate that risk. At present, our
intention remains to continue shipping universal binaries supporting both Apple
Silicon and Intel-based Macs for as long as practical.
