Maintenance status: Not seeing regular published updates, with the last tagged package update at v2.0.1 (2021-11-05), and only an upstream push on 2023-11-01 (suggesting some activity but no recent version cadence).
Last release:
vfile-message is a utility that creates vfile messages, using a (lint) message format with fields like line and column, ruleId, and source. It is useful when you need to emit warnings or errors even when you do not have a vfile-backed file object.
Actively maintained: Yes, there is a recent upstream push and an npm update on 2025-07-26 (version 4.0.3), but after that there have been no further updates through 2026-06-09.
Last release:
vfile-location is a small utility for vfile that converts between positional locations in a text file (line and column) and offset-based locations (range-based index positions). It is useful when you need to search raw file content or report AST findings using line and column coordinates for users.
Maintenance status: Evidence suggests the project is quiet/dormant rather than actively maintained as of 2026-06-09, with the last known upstream push on 2024-10-22 and the newest published updates (5.0.3) on 2024-07-15.
Last release:
vfile is a small, browser friendly virtual file format for text processing, used in the unifiedjs ecosystem. It lets tools attach metadata like path and value, and record lint style messages tied to specific places in the file, which is useful for linters, compilers, static site generators, and other build tools that work with parsed data.
Maintenance status: The source shows some prior active development (notably 6.0.0 through 6.0.3), but since v6.0.3 (2024-08-27) there have been no clearly documented updates in the provided history, and the latest upstream push is 2025-02-04, suggesting it is quiet/dormant rather than actively maintained as of 2026-06-09.
Last release:
uuid is a JavaScript library for generating RFC-compliant UUIDs (RFC9562, formerly RFC4122). It provides APIs to create common UUID versions, validate and parse/serialize UUIDs, and includes a CLI tool, with support for TypeScript and major browsers and environments like Node.js and React Native.
The source (uuidjs/uuid) appears actively maintained, with upstream pushes and multiple recent updates in 2026, including v14.0.1 on 2026-06-20.
Last release:
This software provides the Node.js `util.deprecate()` function in environments with browser support, including use via browserify. It lets developers mark functions as deprecated so callers will see a deprecation warning message.
The source does not appear actively maintained, the last upstream push is 2018-11-11 and the most recent tagged update listed here is 1.0.2 from 2015-10-07, which is multiple years ago as of 2026-06-09.
Last release:
URI.js is an RFC 3986 compliant JavaScript library for parsing, validating, normalizing, resolving, and serializing URIs (and related IRI, IDNA, IPv6, and IPv6 zone identifier forms). It is useful when you need consistent URI handling across browsers and Node.js, including scheme-specific behavior and operations like comparison and dot-segment handling.
The repository appears to have infrequent maintenance activity, with the last upstream push on 2023-12-06, and the most recent version updates shown here dating to 4.4.0 on 2020-08-30.
Last release:
CLI tool that updates caniuse-lite using browser data from Browserslist configuration. It is useful for keeping queries like “last 2 versions” or “>1%” current and helping polyfill tools like Autoprefixer or Babel use up to date browser information.
The repository appears to be maintained, with an upstream push on 2026-05-20, but the last published updates shown here are from 2025-12-16 (v1.2.3), so end-user cadence has slowed since then.
Last release:
This package provides a utility function, `visitParents`, to recursively walk a Unist syntax tree with depth-first traversal while also passing the full stack of ancestor nodes to your visitor callback. It is useful when you need to process nodes based on their context in the tree, such as handling a node type while also knowing every parent type.
Actively maintained status: likely not, the most recent upstream push and published update are from 2025-10-16, which is about 8 months ago relative to 2026-06-09, and the changelog shows mainly TypeScript and tooling refinements rather than ongoing feature work.
Last release:
unist-util-visit is a utility for working with Unist syntax trees, letting you walk the tree and run a visitor function on matching nodes. It provides helpers to continue traversal, skip child traversal, and exit early, which is useful for tasks like processing or inspecting nodes in a tree structure.
The source appears actively maintained, with the most recent upstream push and documented updates occurring on 2026-01-22 (v5.1.0), which is within about 4.5 months of today (2026-06-09).
Last release:
A small unifiedjs utility that pretty prints the positional info (line and column, or start to end) from a UNIST node, position object, or point. It outputs a standard human-readable string that’s useful for showing where something occurred in an original document, such as in error or warning messages.
Maintenance status: Quiet or maintenance-mode, no upstream push since 2023-07-07 (today is 2026-06-09), so it appears to be largely dormant rather than actively maintained.
Last release:
unist-util-position-from-estree is a small utility that creates a proper unist position (line, column, and offset) from an Estree node. It is useful when you need to run other unist utilities with code parsed into Estree nodes.
Maintenance status: Not actively maintained as of today, last upstream update was in 2023-07-07, so the repo appears quiet/dormant (no evidence of recent ongoing work).
Last release:
unist-util-position is a utility for unifiedjs that helps access positional information on unist syntax tree nodes. It provides functions like position(node), pointStart(node), and pointEnd(node), useful when you need node locations (for example when building or validating plugins that may encounter dirty position data).
Maintenance status: The repo’s last upstream push was 2023-07-07, and the most recent published updates are from 2023-07-07, suggesting the project is no longer actively updated as of today (2026-06-09).
Last release:
unist-util-is is a small utility for checking whether a UNIST node matches a given test, such as a specific node type or a set of required properties. It’s useful for avoiding repeated node-type and structure checks when working with syntax trees.
Maintenance status: The source appears actively maintained, with an updates push on 2025-10-22 and a latest published update (6.0.1) on 2025-10-16, which is within the last year of today (2026-06-09).
Last release:
Undici is an HTTP/1.1 client written from scratch for Node.js. It is useful for making HTTP requests, and it also provides APIs like fetch, request, streaming helpers, and connection pooling configuration.
Actively maintained: The upstream GitHub push was 2026-07-09, and recent updates are coming in over consecutive weeks (v8.4.1 in 2026-06-08, v8.5.0 around 2026-06-15, v8.6.0 in 2026-07-02, v8.7.0 in 2026-07-04). This indicates ongoing active development rather than maintenance mode.
Last release:
Unbox a boxed JavaScript primitive value (for example, Boolean, String, Number, BigInt, or Symbol) back into its underlying primitive. Useful when you need to extract the primitive safely across realms or if you want to avoid relying on `instanceof` or mutable properties.
The most recent evidence of upstream activity is an upstream push on 2025-12-30, but the newest published update in the provided summaries is v1.1.0 on 2024-12-16. Overall, this looks like low-frequency maintenance rather than fast iteration.
Last release:
TypeScript is a language for application-scale JavaScript that adds optional types, and then compiles to readable, standards-based JavaScript. It is useful if you want stronger tooling for large JavaScript applications while still generating plain JavaScript output.
TypeScript (microsoft/TypeScript) appears actively maintained, with the upstream repo having a recent push on 2026-06-02 and continued update activity through the v6.0 line (beta, RC, and patch updates).
Last release:
typed-array-length provides a JavaScript helper that returns the length of a Typed Array, or false if the value is not a Typed Array. It is designed to work across realms and engines, including cases where the length property is overridden.
Actively maintained: The most recent upstream push is 2026-05-28, and the latest published item shown is v1.0.8 on 2026-05-28, indicating continued maintenance activity.
