`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.
The project appears to be maintained only intermittently. The most recent upstream push was 2025-12-30, but the most recent versioned updates in the provided history are v1.2.7 (2022-09-23), suggesting long periods without published updates.
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: The repository shows a tagged update in v2.0.0 on 2025-03-23, and the last upstream push is 2026-06-01, but there are no additional tagged updates shown since 2025-03-23, so as of 2026-06-09 it appears largely quiet or in maintenance mode, with at least some recent activity not yet reflected in published updates.
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.
Active maintenance: Evidence shows at least some ongoing upstream activity (last upstream push on 2025-12-30), but no new published update is listed after v1.2.2 (2025-02-05), so from a consumer perspective it looks more like low-frequency maintenance than active day-to-day releases.
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).
Maintained status appears quiet or in maintenance mode, last upstream update was 2024-04-30, with no evidence of ongoing updates since then (as of 2026-06-09).
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.
The project shows signs of continued attention, with an upstream push on 2026-04-29, but the most recent published npm update was v1.1.0 on 2024-12-02, so day-to-day maintenance appears sporadic.
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.
Actively maintained: Evidence is mixed. The most recent published update in the provided summaries is v2.1.1 on 2025-01-23, but there is a GitHub upstream push on 2025-12-30, suggesting some ongoing work even though no newer version is shown here.
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.
Maintenance status: The repo shows an upstream push on 2025-12-30, which suggests ongoing maintenance activity, but the last published npm updates are older (v3.0.5 on 2024-12-16).
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.
Maintenance status: Not actively maintained as of today, with the most recent published updates dated 2021-11-04, and no evidence of further version updates since then (latest upstream push shown is 2022-11-23).
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 source does not look actively maintained today, the most recent published updates in the provided history are from 2021-11-04 (v2.0.1), and there have been no newer versioned updates shown since then.
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 upstream GitHub push and latest tagged update (v1.1.0 on 2024-12-13) are now about 18 months old (as of 2026-06-09), so this source looks quiet or in maintenance mode rather than actively maintained.
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).
The upstream last push for jensyt/imurmurhash-js was in 2013-08-24, and there have been no further updates since, indicating the source is effectively dormant or in maintenance mode (not actively maintained as of 2026-06-09).
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: Yes. The repo shows a recent update in 2026-02-25 (v4.0.0), indicating ongoing attention rather than maintenance-only status.
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.
Actively maintained: Upstream shows a recent push (2026-03-19), suggesting ongoing development, but the most recent published update in the provided history is 9.0.1 (2025-02-19), so published update cadence since then is unclear.
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.
Actively maintained status, not supported by evidence, upstream last push was 2023-07-31, and there have been no reported updates since then, so this appears quiet or in maintenance mode as of 2026-06-09.
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.
The repo appears largely quiet since its last upstream push on 2025-02-19 (about 16 months ago relative to 2026-06-09), so it does not look actively maintained right now.
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.
Maintenance status: The last recorded upstream push and published update is 2025-03-05, which is about 15 months ago as of 2026-06-09, so the project appears quiet/dormant rather than actively maintained.
Last release:
