Punycode.js is a JavaScript library that converts between Punycode (ASCII) and Unicode strings, fully complying with RFC 3492 and RFC 5891. It is useful for encoding and decoding internationalized domain names or email address domains (e.g., using functions like decode, encode, toUnicode, and toASCII).
The repository appears quiet in the present day: the last upstream push was 2024-04-18, and the most recent published updates listed are from 2023-12-19 (so there have been no new updates for well over a year relative to 2026-06-11).
Last release:
obug is a lightweight JavaScript debugging utility, forked from debug, with TypeScript and native ESM support. It helps developers enable and disable debug output by namespace (for example via the DEBUG environment variable or browser localStorage), and provides customizable formatting and logging with a small footprint for modern runtimes.
Actively maintained, as shown by a recent upstream push on 2026-07-16 and subsequent updates (v2.1.4 on 2026-07-16, with the latest activity in July 2026).
Last release:
NWSAPI is a fast CSS Selectors API engine written in pure JavaScript, built to aim for Selectors Level 4 conformance. It provides functions to parse and compile CSS selector strings for DOM selection and matching, and it can be used in browsers (as a global `NW.Dom`), or in headless environments and Node.js (as a CommonJS module).
The repository (dperini/nwsapi) appears to have recent activity, with an upstream push on 2026-06-07, which suggests it is not abandoned.
Last release:
Nano ID is a tiny, secure, URL-friendly unique string ID generator for JavaScript, designed to create short IDs with a URL-safe alphabet. It supports secure and non-secure modes (using hardware random generation by default) and can be customized by ID size or alphabet.
Actively maintained. Evidence shows very recent upstream activity (last push 2026-08-10) and multiple npm/package updates in 2026, including fixes and packaging refactors as recently as 2026-08-07 (v3.3.18).
Last release:
MZ (Modernize node.js) is a Node.js helper library that modernizes Node’s core APIs to current ECMAScript specifications, especially by wrapping parts of Node’s API. It provides promise-based versions of common modules like child_process, crypto, dns, fs, readline, and zlib, so you can use async functions cleanly with Node’s core APIs.
Maintenance status: The repository appears quiet/dormant now, with the last upstream push in 2020-12-11 and the most recent published updates listed in 2017-09-13 (v2.7.0), so there is no clear sign of active maintenance as of 2026-06-11.
Last release:
ms (vercel/ms) is a small utility for converting time expressions and units to milliseconds, and converting millisecond numbers back into formatted strings with units. It’s useful when you need consistent parsing of inputs like “2 days”, “1h”, or “100”, including TypeScript type definitions and support for different server and browser runtimes.
Maintenance status (evidence-based): The repo shows a recent upstream push on 2026-05-20, which suggests it is not completely dormant, but the provided “updates” list is otherwise old (latest shown is 3.0.0-canary.1 from 2021-09), so public update cadence appears very infrequent.
Last release:
min-indent is a small JavaScript utility that finds the shortest leading whitespace shared by non-empty lines in a string, then uses that value to remove redundant indentation. It is useful for normalizing multi-line strings that include extra indent.
The upstream repo appears not to be actively maintained, with the last upstream push on 2020-08-02 and only a small number of updates since then.
Last release:
markdown-table generates GitHub flavored markdown (GFM) tables from table data (a matrix of strings). It is useful when you want to produce markdown table source code from existing data, with options to control alignment, padding, delimiters, and delimiter alignment.
Maintenance status: Not actively maintained as of today (2026-06-11), with the most recent upstream update on 2024-10-22. The long gap (about 1.5 years) suggests the project is quiet/dormant rather than in active development.
Last release:
LZ-string is an LZ-based compression algorithm implemented for JavaScript, useful for compressing and decompressing text data in web or Node.js applications. It also provides a command line tool (if installed globally) to compress or decompress files, with options for different character encodings.
The source does not appear actively maintained in terms of published library updates, with the newest shown update being 2.0.0-rc.0 on 2023-06-20, and no later update information provided up to today (2026-06-11). While the upstream repo shows a push on 2025-08-11, there are no corresponding update/release notes in the provided data.
Last release:
A fast LRU (least recently used) cache for JavaScript that automatically evicts the least recently accessed items when it reaches configured limits like max item count (or max size). Useful for speeding up repeated lookups where you want bounded memory and eviction based on recent access, with optional TTL behavior that treats expired items as missing.
Actively maintained: Recent upstream push on 2026-07-07 and multiple published updates in 2026 (from 2026-05-04 through 2026-07-07) indicate the project is being actively worked on rather than in maintenance mode.
Last release:
A JavaScript library for validating and working with BCP 47 language tags, based on BCP 47 (RFC 5646) and the latest IANA language subtag registry. It provides functions to check tag validity, look up language subtags, search subtags and tags by description, and format tags according to common conventions (case rules).
The source (mattcg/language-tags) looks largely in maintenance mode, with the last upstream push dated 2025-07-07 and the most recent tagged update being v1.0.5 on 2016-01-12 (as of 2026-06-11, that is years ago).
Last release:
Keyv is a simple key-value storage library for JavaScript and TypeScript that provides a consistent interface across multiple backends using storage adapters. It supports TTL-based expiry, which makes it useful for building caches or persistent key-value stores.
Keyv (jaredwray/keyv) appears actively maintained, with very recent upstream and repo activity (last upstream push 2026-08-05, and updates on 2026-08-04 including v6.0.1).
Last release:
JSON5 is a JavaScript library that extends the JSON file format to be easier to write and maintain by hand, mainly for config files. It provides parsing and serialization (JSON5.parse, JSON5.stringify) and includes a CLI for converting JSON5 to JSON and validating JSON5 syntax.
Maintenance status (2026-06-11): The repository shows no recent version updates beyond v2.2.3 (2022-12-31), even though the GitHub upstream was last pushed on 2024-10-25, which suggests the project is largely quiet in terms of public updates (maintenance mode rather than active feature development).
Last release:
jsdom is a pure JavaScript implementation of many web standards, notably the WHATWG DOM and HTML standards, designed to run in Node.js. It emulates enough of a browser environment to help with testing and scraping real-world web applications by parsing HTML into a DOM-like `window` and related APIs.
jsdom/jsdom appears actively maintained, with upstream pushes and multiple recent updates in July 2026 (including v30.0.1 and v30.0.0 just days apart, plus earlier CSS-focused updates in April 2026).
Last release:
`jose` is a JavaScript module for working with JOSE standards, including JSON Web Tokens (JWT), JSON Web Signature (JWS), JSON Web Encryption (JWE), and JSON Web Keys (JWK, JWKS). It provides tools to sign, verify, encrypt, decrypt, import/export keys, and validate JWT claims across multiple Web-interoperable runtimes such as Node.js, browsers, Cloudflare Workers, Deno, and Bun.
Actively maintained: Recent upstream pushes in 2026-08 (latest noted 2026-08-24) and multiple tag updates through 2026-08-21 indicate ongoing maintenance and active development for the panva/jose parser source.
Last release:
Jiti is a Node.js runtime tool that provides seamless TypeScript and ESM support, including interoperability between ESM and CommonJS. It can load TypeScript/ESM files via async APIs similar to `import()` or via a sync API similar to `require()`, and it supports features like ESM loader registration, filesystem transpile caching, and custom module resolution (including aliases).
Actively maintained: The most recent upstream push is 2026-06-10, and there is a recent v2.7.0 update (2026-05-05), indicating ongoing work rather than maintenance mode.
Last release:
Checks whether a given value is a JavaScript string, either as a primitive or as a String object. It is designed to work across realms like iframes, which helps when validating values in different execution contexts.
Actively maintained: The most recent recorded upstream activity is an upstream push on 2025-12-30, but the most recent published updates are v1.1.1 (2024-12-16) and v1.1.0 (2024-12-02). Relative to today (2026-06-11), this suggests low activity rather than continuous active maintenance.
Last release:
Checks whether a given string matches the HTML Standard’s `PotentialCustomElementName` production. Useful in JavaScript to validate candidate custom element names before using them.
The repository appears maintained at least through 2021, with a recent update (v1.0.1 on 2021-04-07), but prior activity is much older (v1.0.0 dated 2016-06-21).
