This package returns an array of Typed Array names that are available in the current JavaScript environment. It is useful for runtime feature detection before using specific Typed Array types (for example, checking support for Float16Array or BigInt64Array).
Actively maintained is unclear, but there is evidence of recent repository activity: the upstream last push was 2026-03-10, while the latest documented package update was v1.0.7 on 2024-02-19.
Last release:
async-function is a small package that returns the normally hidden AsyncFunction constructor when it is available. It is useful if you need to create async functions dynamically (for example, by calling new AsyncFunction(...) with a function body).
The source appears to be quiet-to-low activity: the provided evidence shows a last upstream push on 2026-04-21, but the most recent documented update/tag is v1.0.0 from 2025-01-23, with no newer update summaries included.
Last release:
Astring is a tiny, fast JavaScript code generator that turns an ESTree-compliant AST into JavaScript source code. It’s useful for projects that need to generate code (optionally with source maps and comments) from ASTs produced by parsers like Acorn or Meriyah.
Maintenance status: The most recent upstream activity was 2024-12-01, and the newest recorded GitHub update is v1.9.0 on 2024-08-25, so relative to 2026-06-09 the project appears quiet and likely in maintenance mode rather than actively maintained.
Last release:
Provides Flow type definitions for the JavaScript AST (based on benjamn/ast-types), so you can import `ast-types-flow` types like `Node` in Flow-typed code. It includes a transform that compiles “extends” relationships expressed in comments into disjoint union types to help model different AST node shapes accurately.
The source appears not actively maintained, with the last upstream push on 2023-04-15, which is over 3 years ago relative to 2026-06-09.
Last release:
ES spec-compliant shim for `ArrayBuffer.prototype.slice`, provided for JavaScript environments where it may be missing or unsupported. Useful if you need to create sliced `ArrayBuffer` instances consistently, by calling the `shim` method when `ArrayBuffer.prototype.slice` is unavailable.
This GitHub update source appears to be quiet rather than actively maintained, with the last upstream push on 2024-12-15, and no evidence of activity since then (as of 2026-06-09).
Last release:
Provides an ESnext spec-compliant shim or polyfill for `Array.prototype.toSorted`, letting you use the proposed `toSorted` behavior in environments down to ES3. It can be used either as a function that takes the input array, or via `shim()` to install `Array.prototype.toSorted` when it is missing.
Maintenance status: The last upstream push and published update are from 2024-06-03, and there have been no evidence-backed updates since then, so the project appears quiet or in maintenance mode rather than actively maintained as of 2026-06-09.
Last release:
An ES2019 spec-compliant `Array.prototype.flatMap` shim, polyfill, or replacement designed to work in environments down to ES3. Useful for adding `flatMap`-style behavior to older JavaScript engines, with a API that exports a function taking the array as the first argument (because `flatMap` depends on the receiver `this`).
Maintenance status: Appears not actively maintained in terms of published package updates, with the most recent published update v1.3.3 dated 2024-12-16 (about 1.5 years ago as of 2026-06-09). However, there was an upstream push on 2025-12-30, suggesting some ongoing repository activity despite no corresponding new published updates shown here.
Last release:
This is an ES2019 spec-compliant `Array.prototype.flat` shim or polyfill for flattening nested arrays, implemented to work in environments as old as ES3. It provides a main export that takes the target array as the first argument and can also supply a `shim()` that replaces or matches `Array.prototype.flat` behavior when needed.
The source appears maintained, with the most recent tagged update v1.3.3 dated 2024-12-15, and an additional upstream push on 2025-12-30, though detailed release notes are not provided for recent updates.
Last release:
An ESnext spec-compliant shim or polyfill that provides `Array.prototype.findLastIndex`, including in older ES3-supported environments. Useful for codebases that need consistent `findLastIndex` behavior and can either call the exported function with an array argument or use `.shim()` to ensure `Array.prototype.findLastIndex` is available.
Maintenance status: Appears to be in maintenance mode rather than actively maintained, with the most recent update on 2025-03-14 and no evidence of updates since then (as of 2026-06-09 this is about 15 months ago).
Last release:
A JavaScript shim or polyfill for the proposed ESnext `Array.prototype.findLast`, letting you search from the end of an array to find the last element that matches a predicate. It is designed to work in older ES3-supported environments and provides a main export that takes the array as the first argument due to `this` receiver behavior.
Maintenance status: Updates last published in March 2024 (latest v1.2.5 on 2024-03-19), which is over 2 years ago relative to today (2026-06-09), suggesting the project is quiet/dormant or in maintenance mode rather than actively maintained.
Last release:
This is a spec-compliant shim/polyfill for `Array.prototype.includes`, implemented to work in older JavaScript environments down to ES3. It provides a drop-in `includes(array, value[, fromIndex])` function and can also expose a `shim()`/`getPolyfill()` result when `Array.prototype.includes` is missing.
This source (es-shims/array-includes) appears intermittently maintained. The most recent observed activity is an upstream push on 2025-12-30, and the latest listed package update is v3.1.9 on 2025-06-02, after a long gap since v3.1.8 (2024-03-20).
Last release:
array-buffer-byte-length is a JavaScript utility that returns the byte length of an ArrayBuffer, including in environments that do not provide a `.byteLength` method. It can be used as a shim or polyfill, for example to support consistent byte-length checks and to return NaN for non-ArrayBuffer inputs.
The repository shows ongoing activity (upstream push on 2026-01-13), but the provided tagged v1.x updates are older (latest shown is v1.0.2 on 2024-12-20), suggesting maintenance rather than frequent updates.
Last release:
ARIA Query provides programmatic access to the WAI-ARIA 1.2 roles model, tracking the W3C Recommendation updates. It lets you look up ARIA role definitions and map between roles and HTML elements (including cases that depend on specific attributes like input type).
Actively maintained: Evidence suggests the project is quiet/dormant today, with the last upstream push on 2024-12-06 and the newest listed update v5.3.2 on 2024-09-20 (roughly 18 months before 2026-06-09).
Last release:
Arg is an unopinionated CLI argument parser for Node.js. It parses command line flags into an object (consumed options become properties, extra positional values go into `result._`) and supports basic types, aliases, and permissive parsing behavior. It is useful for turning `process.argv` into structured inputs for command line tools.
Maintenance status: The repo has an upstream push as of 2024-07-18, but the most recent published updates shown here are older (5.0.2 on 2022-06-05), suggesting a long, quiet maintenance cadence rather than active, frequent development (as of 2026-06-09).
Last release:
anymatch is a JavaScript module that matches a string against configurable matchers such as regular expressions, glob patterns, direct strings, or functions (or arrays mixing these). It is useful for flexible, user-defined configuration like matching file paths, and it can optionally return the index of the first matching matcher instead of just a boolean.
Maintenance status: Evidence suggests low-activity maintenance mode, with the last upstream push dated 2023-05-18 and the most recent documented updates (v3.1.3) on 2022-11-21. No signs of frequent ongoing work near today (2026-06-09).
Last release:
Any Promise lets a library work with any ES2015-compatible Promise implementation chosen by the application author. An application can optionally register its preferred Promise (including a global or browser Promise), and libraries can require `any-promise` to get that selected implementation. It can also help older Node.js versions where the global Promise may be unreliable.
The GitHub source (kevinbeaty/any-promise) appears quiet and effectively dormant, with the last upstream push on 2018-10-01 and the most recent tagged updates dating back to 2016, which is long before 2026-06-09.
Last release:
Ajv is a fast JSON schema validator for Node.js and browsers. It supports JSON Schema draft-04/06/07/2019-09/2020-12 and JSON Type Definition (RFC8927), useful for validating JSON data against schema definitions.
Actively maintained, upstream has recent activity (last push 2026-05-12) and multiple version updates in 2026 (v8.18.0 on 2026-02-14, v8.19.0 and v8.20.0 on 2026-04-24).
Last release:
Node.js HTTP Proxy Agents monorepo providing HTTP agent implementations that route traffic through proxies using different protocols, with support for HTTP/HTTPS and related proxy technologies. It’s useful if you’re looking for Node.js “agent” modules to send requests via proxies, and the guidance suggests using proxy-agent for the most common cases.
Actively maintained, as shown by multiple upstream updates on 2026-06-08 across the monorepo packages (http-proxy-agent, https-proxy-agent, proxy, proxy-agent-negotiate, socks-proxy-agent, pac-proxy-agent, proxy-agent), with the last upstream push at 2026-06-08 16:47 UTC.
