Define multiple non-enumerable properties on an object at once. It uses Object.defineProperty when available, and falls back to standard assignment in older engines, without overriding existing properties unless predicate functions indicate force-overrides.
Maintenance status: Evidence is mixed, but the GitHub “last upstream push” is 2025-12-30, which suggests the repo is not completely abandoned. However, the most recent published update in the provided history is v1.2.1 (2023-09-13), indicating overall low-churn maintenance.
Last release:
This software defines a data property on a JavaScript object, including configurable, enumerable, writable, and value settings. It can fall back to simple assignment in engines without descriptor support, and the optional `loose` mode can also fall back when setting non-normal data properties.
Maintenance status: The repository shows an upstream push on 2026-01-13, but the most recent published updates in the provided data are from 2024-02-13 (v1.1.4), so it looks low-cadence (possibly still maintained, but not actively publishing frequent updates).
Last release:
A standalone Node.js module that compares two values using the same recursive equality behavior as assert.deepEqual, but treats NaN as equal to NaN. Useful for writing deep equality checks in JavaScript where the default deepEqual behavior differs for NaN.
The repository appears not to be actively maintained, with the most recent upstream push and latest listed update dated 2021-09-04, which is well over four years ago as of 2026-06-09.
Last release:
Decode named character references (for example, converting `amp` to `&`). It is an ES module package, intended as a workaround for webpack, and the author advises using `parse-entities` instead.
Actively maintained: The most recent update is 1.3.0 on 2026-01-19, with an upstream push on the same day, indicating current active maintenance as of 2026-06-09.
Last release:
date-fns is a modern JavaScript date utility library for working with dates in both the browser and Node.js. It offers 200+ modular, pure, immutable functions and includes TypeScript support and many locales to format and manipulate native JavaScript Date objects.
Actively maintained, with ongoing GitHub activity (last upstream push on 2026-06-02) and multiple recent updates in late May 2026, including a v5.0.0-alpha.0 (2026-05-29).
Last release:
Provides a small helper to extract the `byteOffset` value from a JavaScript `DataView`, handling edge cases across older and modern Node and browser engines. Useful when you need a reliable byte offset even when `DataView.prototype.byteOffset` is missing, deleted, or not exposed as a prototype accessor.
The source appears to be maintained at least intermittently, with a recent upstream GitHub push on 2026-01-13, but the published “updates” (tags/releases) are sparse in the record provided (2024-12-19, 2024-03-04).
Last release:
Provides a small JavaScript helper to get the `byteLength` value from a `DataView` object in a robust way. Useful when you need consistent access across older Node versions and engines where `DataView.prototype.byteLength` may be missing or deleted.
The source appears to be lightly maintained: there was an upstream GitHub push on 2026-01-13, but the most recent published update is v1.0.2 from 2024-12-20.
Last release:
This package provides a function to extract the underlying ArrayBuffer from a JavaScript DataView reliably across different JavaScript engine behaviors. It is useful when you need access to the original ArrayBuffer for tasks like low-level binary inspection or manipulation.
The source appears to be maintained in the sense that the upstream repository has a recent push (last upstream push on 2026-01-13), but the publicly documented versioned updates are older (latest tagged update v1.0.2 on 2024-12-20).
Last release:
JavaScript library for Node.js that calculates the Damerau Levenshtein distance between two strings. It returns an object with the edit steps, a relative value based on the longer string length, and a derived similarity score useful for string comparison and fuzzy matching.
Maintenance status: The npm/package updates appear to be largely maintenance-light, with the newest published update being v1.0.8 on 2021-12-20. Although the GitHub upstream has a push in 2024-07-19, there is no evidence in the provided release summaries that those changes resulted in newer published updates.
Last release:
CSSType provides strict TypeScript and Flow type definitions for CSS properties and values, generated from MDN data. It helps with autocompletion and type checking when writing CSS-in-JavaScript or otherwise working with CSS property objects.
Maintenance status: The repository appears to be in active development, with an upstream push on 2026-04-10. However, the provided published updates in the list are latest at v3.2.3 (2025-11-17), so the most recent tag/release activity in the evidence is several months old.
Last release:
cssesc is a JavaScript library that escapes text for use in CSS strings or CSS identifiers, generating the shortest possible ASCII-only output. It exposes a `cssesc(value, options)` function (including `isIdentifier`, `quotes`, and `wrap`) and also provides a command-line `cssesc` tool for escaping from a shell.
The repository appears to be no longer actively maintained, with the last upstream push dated 2023-02-02, which is over 3 years ago relative to today (2026-06-09).
Last release:
cross-spawn is a cross-platform drop-in replacement for Node.js spawn and spawnSync, intended to avoid Windows issues like PATHEXT handling, shebang support, commands with spaces, and problems with posix relative paths. It provides the same usage shape as Node, using spawn and spawn.sync, to help run child processes more consistently across platforms.
The repository shows no upstream push since 2024-11-18 (about 19 months ago as of 2026-06-09), so it does not look actively maintained right now, more like in quiet or maintenance mode.
Last release:
core-js is a modular JavaScript standard library that provides polyfills (shims) for ECMAScript features and some web standards, with options to load only the parts you need. It helps developers use modern JavaScript features in environments that may not support them, and it can be used without polluting the global namespace (for example via core-js-pure).
Actively maintained, evolving: Recent activity includes a new branch/tag for v4.0.0-alpha.1 (2026-03-22) and a recent upstream push (2026-06-03), with frequent v3.x updates through early 2026.
Last release:
cookie is a basic JavaScript (Node.js) HTTP cookie parser and serializer. It helps you parse Cookie and Set-Cookie header strings into objects, and stringify those objects back into header values, with options for encoding and decoding.
Actively maintained, with very recent activity (last upstream push on 2026-07-01, and updates through v2.0.1 on 2026-06-30).
Last release:
concat-map is a small Node.js module that creates a new array by calling a function on each element (and its index) and concatenating the results. It is useful when you want to map an array where each callback invocation can return an array (which gets flattened into the output) or a single value (which gets appended).
The repository shows only a small number of tagged updates: v0.0.2 in 2022-10-12, after earlier v0.0.1 (2014-01-30) and v0.0.0 (2012-06-08). While there was an upstream push on 2025-12-30, there is no evidence of new published versioned updates since 2022.
Last release:
This package parses and stringifies comma-separated tokens according to the WHATWG spec, providing `parse(value)` to turn a string into an array of strings and `stringify(values, options)` to serialize them back. It is useful for working with HTML token lists, especially when working with `hast`.
The repository appears quiet, with no upstream or package updates since 2022-11-14, so it is not actively maintained as of today (2026-06-09).
Last release:
combined-stream provides a stream that emits multiple other streams one after another, useful for combining several readable streams into a single output stream. It supports queuing streams via append, optional back pressure (pauseStreams), and buffering limits (maxDataSize) to help manage resource use.
The source appears effectively dormant, with the last upstream push on 2023-11-09 and the most recent recorded package update on 2019-12-30 (over 6 years ago from today, 2026-06-09).
Last release:
This small JavaScript and HTML-oriented package collapses multiple whitespace characters in a string into a single character (defaulting to a space). It can optionally trim leading and trailing whitespace, and it can preserve line endings when collapsing. Useful for normalizing whitespace in HTML or JavaScript text.
This GitHub source appears quiet, with the last upstream push on 2022-11-16, and no new updates shown in the provided recent history since 2.1.0 (2021-10-27), so it is not actively maintained as of 2026-06-09.
