`is-core-module` checks whether a given module specifier refers to a Node.js core module, optionally using a specific Node.js version (defaults to the current version). It is useful in Node tooling and libraries that need to branch logic based on whether a dependency is built into Node or comes from userland.
The source appears actively maintained, with an upstream push and recent package update on 2026-05-05 (about 4 months before 2026-09-03), indicating ongoing attention rather than dormancy.
Last release:
This JavaScript utility checks whether a value is callable, returning true for functions and generator functions and false for non-callable values. It is useful for validating inputs before invoking them and it includes compatibility notes across common JavaScript engines.
Maintenance status: inspect-js/is-callable looks mostly quiet in terms of published updates (latest detailed update info is v1.2.7 in 2022-09-23), though there is an upstream push on 2025-12-30 suggesting some activity after that date.
Last release:
is-bun-module is a JavaScript and TypeScript utility library that helps you determine whether a module specifier refers to a Bun built-in module, a Node module implemented in Bun, or either (Bun built-in). It also provides functions to list Bun modules and Node modules implemented in Bun (optionally for a specific Bun version, with only Bun v1.0.0+ supported).
Maintenance status: Recent upstream push on 2026-09-01, but the most recent published updates tag is v2.0.0 (2025-03-23), so the library appears not regularly released, with maintenance or quieter period since 2025 despite continued development activity.
Last release:
This module checks whether a value is a JavaScript Boolean, including boxed Boolean objects. It is useful for type validation and works across realms or iframes, even when ES6 @@toStringTag is present.
The source appears to be in maintenance mode rather than actively evolving: the most recent published update was v1.2.2 on 2025-02-05, and there has been no newer published update since, though the upstream repo shows a push on 2025-12-30.
Last release:
This package helps you check whether a given file path points to a binary file. It returns true or false for paths like image files (for example, a .png) versus text files (for example, a .txt).
The source shows updates through 2024-04-30 (v3.0.0), with no evidence of any updates since then, so it appears quiet or effectively in maintenance mode as of 2026-09-10.
Last release:
is-bigint is a JavaScript utility that checks whether a value is an ES BigInt, including cases like `1n` and `Object(1n)`. It is useful for adding type guards before you use BigInt-specific logic in your code.
Maintenance status: Evidence suggests light, ongoing maintenance (there was an upstream repo push on 2026-04-29), but the published package updates appear infrequent. The latest published update observed here is v1.1.0 (2024-12-02).
Last release:
is-async-function is a small JavaScript utility that checks whether a value is a native async function. It is useful for runtime type checks when you need to detect async functions versus regular, generator, or non-function values.
The source appears to be quiet rather than actively maintained as of today (last observed published update was v2.1.1 on 2025-01-23, over 1.5 years ago), though there is an upstream push timestamp on 2025-12-30 that suggests some ongoing repository activity without a new published version.
Last release:
This module checks whether a given value is a JavaScript ArrayBuffer. It is designed to work across realms and iframes without relying on instanceof or mutable properties, making it useful for type checks in JavaScript codebases.
The source appears largely in maintenance mode, with the latest known published update being v3.0.5 on 2024-12-16, while the most recent upstream push recorded is 2025-12-30 (about 1.6 months before, but still roughly 21 months from the latest published update as of 2026-09-10).
Last release:
is-alphanumerical is a small ESM function that checks whether a given character (ASCII code point) matches `[a-zA-Z0-9]`. It’s useful when you need a shared helper to test alphanumeric characters in JavaScript, including Node.js, Deno, and modern browsers.
The source appears to be maintained in bursts, but based on the latest evidence it is effectively quiet/dormant now, with the last upstream push on 2022-11-23 and the most recent published update (2.0.1) on 2021-11-04, which is several years ago relative to 2026-09-10.
Last release:
is-alphabetical is a small ESM JavaScript/TypeScript function that checks whether a given character is an ASCII alphabetical character (matching [a-z], case insensitive). It returns true for letters like “a” and “B”, and false for non-letters, and is useful when you need this check as a shared helper across multiple packages.
The repository shows no upstream push since 2022-11-23, and the most recent packaged update appears to be from 2021-11-04 (2.0.1), so maintenance looks quiet or in maintenance mode rather than actively evolving as of 2026-09-10.
Last release:
internal-slot is a JavaScript utility that provides truly private per-object storage similar to the JS spec’s internal slots. It uses WeakMap when available, otherwise falls back to Map or an object, which helps modules store hidden values with environment-dependent performance and garbage collection behavior.
The ljharb/internal-slot source appears quiet or in maintenance mode, with the last upstream push on 2024-12-13 (over 1.5 years ago as of 2026-09-10), and no newer updates shown in the provided history.
Last release:
Inline style parser for JavaScript and Node.js, published as an npm package. It parses CSS inline style strings into structured declaration objects (property, value, and position), useful for turning style text like `color: #BADA55;` into data for further processing.
Actively maintained, most evidence shows ongoing development with an upstream push on 2026-07-06, and additional updates just days earlier (v0.2.8 on 2026-07-03).
Last release:
iMurmurHash.js is an incremental JavaScript implementation of the MurmurHash3 (32-bit) hashing algorithm. It lets you hash many small strings into a single hash efficiently by updating a hash state as you add text, useful for cases where concatenating strings first would be costly (in both browser and Node.js).
Maintenance status: Quiet and effectively dormant, the last upstream push was 2013-08-24, and there have been no updates in about 13 years as of 2026-09-10.
Last release:
Import-fresh is a Node.js utility for importing an ES module while bypassing the import cache, so code can be reloaded with fresh state. It is useful for development and testing scenarios where you need a freshly imported module, with an optional option to avoid cache-busting modules inside node_modules.
Actively maintained, with the most recent update (v4.0.0) pushed on 2026-02-25, which is relatively recent compared to today (2026-09-10).
Last release:
hastscript is a hyperscript-style helper for creating hast (HTML AST) trees using function calls. It provides `h` for HTML and `s` for SVG, converting simple selectors and children into the hast node structures and normalizing attributes into the form expected by hast.
Active maintenance: Evidence suggests some ongoing work (GitHub upstream push on 2026-03-19), but no published updates since 9.0.1 (2025-02-19), so the project looks more quiet than actively releasing as of today (2026-09-10).
Last release:
hast-util-whitespace is a small utility for hast (HTML AST) that checks whether a given node or string is inter-element whitespace according to HTML rules. It’s useful when you need to detect text nodes that contain only allowed whitespace characters like spaces, tabs, and line breaks.
The source (syntax-tree/hast-util-whitespace) shows no upstream push since 2023-07-31, and its most recent entry is 3.0.0, so it appears quiet or in maintenance mode rather than actively updated.
Last release:
rehype-minify provides plugins to minify HTML, including a preset (rehype-preset-minify) with good and safe default settings. It is useful if you already process HTML with rehype (and possibly remark) and want smaller HTML output.
Maintenance status: The most recent upstream push is 2025-02-19, and there are no later update summaries shown up to 2026-09-10, so the project appears quiet/dormant (maintenance mode at best) rather than actively maintained.
Last release:
hast-util-to-jsx-runtime converts a hast syntax tree into JSX elements for frameworks like Preact, React, Solid, Svelte, and Vue, using an automatic JSX runtime. It is useful when you already have a hast tree and want to render or integrate it with a chosen JSX-based framework.
The source does not appear actively maintained today, with the most recent upstream push on 2025-03-05, about 19 months before 2026-09-10 (so it is effectively quiet/dormant in the near term).
