fast-querystring is a JavaScript, Node.js utility that provides a fast query-string parser and stringifier as a drop-in alternative to the legacy node:querystring module. It supports parse and stringify, handles repeating keys, and can build query strings using & separators, making it useful for converting between query strings and plain JavaScript objects.
Maintenance status: The source shows an upstream push on 2026-04-19, but the most recent listed version update is 1.1.2 (2023-06-05), suggesting quiet or maintenance-mode behavior with limited published updates in the past ~2+ years.
Last release:
fast-memoize is a JavaScript library for memoization, designed to speed up programs by caching results of expensive function calls and reusing them for repeated inputs. It supports memoizing functions with N arguments, and can use a custom cache implementation or a custom serializer to control how arguments are turned into cache keys.
Maintenance status: Not clearly actively maintained as of 2026-08-13, since the most recent published updates appear to be v2.5.2 on 2020-03-04, with the upstream repo push noted on 2023-02-19 but no corresponding newer update evidence in the provided timeline.
Last release:
fast-json-stringify builds a fast JSON `stringify()` function from a JSON Schema (Draft 7), useful when you want faster serialization for small payloads than `JSON.stringify()`. It supports common JSON types and nested schemas, with special handling for values like `Date`, `RegExp`, and `BigInt`, and it is built to generate functions ahead of time using the provided schema.
Actively maintained: The repository shows recent GitHub activity (last upstream push on 2026-08-09) and multiple versioned updates in 2025-2026, including maintenance bug fixes and functional changes.
Last release:
Fast Diff is a fast JavaScript library for computing differences between two strings. It is a simplified Node.js import of diff-match-patch, with only the diffing logic kept, useful when you need quick string diff output.
A JavaScript utility that fast-decodes strings produced by encodeURI and encodeURIComponent. It avoids throwing on invalid escape sequences, returning null instead, and is useful when you need safe URL decoding with better performance than decodeURIComponent.
Maintenance status: Based on the last upstream push in 2019-10-06, this repository appears quiet or dormant rather than actively maintained as of 2026-08-12.
Last release:
fast-copy is a JavaScript library for performing fast deep copies of objects, including support for circular references. It provides a simple `copy` function and a stricter `copyStrict` mode, and you can also build custom high-performance copiers with `createCopier` to override how specific types like arrays, maps, and sets are duplicated.
Actively maintained: GitHub shows very recent activity, with an upstream push on 2026-09-02 and multiple tagged updates on 2026-08-31, indicating ongoing development rather than a dormant period.
Last release:
fast-base64-decode is a fast Base64 decoder for Node.js or browser JavaScript, providing a low level API. It lets you decode a Base64 string into a preallocated Uint8Array, which can be useful when you need performance and control over the output buffer.
The source appears quiet and effectively unmaintained, last upstream push was 2022-10-30, and there have been no recorded updates since then as of 2026-08-12.
Last release:
exit-x is a Node.js module that replaces process.exit to prevent output truncation, especially on Windows when piping or redirecting stdout and stderr. It waits for stdio streams to be fully drained before actually exiting, which is useful for ensuring logs are written completely during shutdown.
The project appears at least somewhat maintained, with the latest upstream push on 2026-04-07. However, the publicly summarized version history only goes up to v0.2.2 (2024-12-04), so recent work may not be reflected in published updates yet.
Last release:
Provides the Node.js `events` EventEmitter module for environments that do not have it, such as browsers. Useful when you need Node-style event emitting in non-Node runtimes, matching the Node 11.13.0 API using ES5 features.
Maintenance status: The provided history shows no new updates since v3.3.0 (2021-02-27), and as of 2026-08-13 this suggests the project is quiet and in maintenance mode rather than actively evolving (even though there was an upstream push on 2024-12-21, no corresponding tagged updates are shown here).
Last release:
An npm package that provides an implementation of the WHATWG EventTarget and Event interfaces for use in JavaScript, with support for event listener options like passive, once, and signal. It is designed to work in both browsers and Node.js and is intended to be TypeScript friendly. Useful when you need consistent EventTarget/Event behavior in environments that do not fully support the standard.
Maintenance status: The source appears quiet or in maintenance mode, with no versioned updates shown since v6.0.2 on 2021-01-07, and the last upstream push only dated to 2023-01-06.
Last release:
ESLint plugin that finds and removes unused ES6 module imports, splitting the usual no-unused-vars handling so imports and other variables are reported separately. Useful if you want an autofixer to delete unused import nodes, while integrating with ESLint and (optionally) @typescript-eslint for TypeScript support.
Actively maintained: the last upstream push was 2026-04-08, which is recent relative to today (2026-08-12), and there were published updates in 2026 (v4.4.0 and v4.4.1).
Last release:
ESLint plugin for Prettier formatting, it runs Prettier as an ESLint rule and reports formatting differences as individual ESLint issues. Useful for enforcing consistent Prettier output during linting, and it recommends disabling conflicting ESLint formatting rules via `eslint-config-prettier`.
The source appears actively maintained, with an upstream push on 2026-08-02 and multiple tagged updates in 2025 and 2026 (latest noted update v5.5.6 on 2026-05-28).
Last release:
eslint-config-prettier provides an ESLint configuration that turns off all rules that are unnecessary or might conflict with Prettier, so your shared ESLint setup does not interfere with Prettier formatting. It is intended to be used alongside another config, and it can also include a CLI helper tool to check for conflicting or redundant rules.
Maintenance status: The repo shows a very recent upstream push (2026-08-13), but the most recent published package updates in the provided history are from 2025-07-18, about a year ago, so released changes appear quiet for this period.
Last release:
ES Proposal spec-compliant shim for `AggregateError` in JavaScript. It provides an API to install a compliant `AggregateError` implementation when the global version is unavailable or noncompliant, and is intended to work in ES3-supported environments.
Maintenance status: Seems maintained but with a relatively low, irregular cadence. The upstream repo had a push on 2025-12-30, but the last published package update in the provided summaries is v1.0.14 on 2025-06-02.
Last release:
A small JavaScript utility (err-code) for creating Error instances that include a code and optional additional properties. It helps standardize how you set error.code (and related fields) when throwing errors, including preserving the original message and stack.
Maintenance status: Evidence suggests the repo is quiet or effectively in maintenance mode, with the last upstream push on 2022-06-22 and no newer documented updates shown beyond 2021-02-02 (v3.0.0).
Last release:
This Node.js module provides a helper that calls a callback when a readable, writable, or duplex stream completes or fails. It is useful for reliably detecting when streams end or error, including early close behavior, and it supports legacy stream types.
Maintenance status: The repo appears quiet/dormant today, with the last upstream push on 2025-06-16, about 14 months ago (no evidence of continued active maintenance since then).
Last release:
enabled is a small utility that checks whether a given namespace name matches a flag defined via environment variables, converting those variables into regular expressions for matching. It returns a boolean, and it is useful in browsers and servers (ES3 compatible) to gate behavior based on configurable enabled patterns.
This GitHub source (3rd-Eden/enabled) appears quiet or in maintenance mode, with its last upstream push on 2020-02-25, and no evidence of recent activity relative to today (2026-08-12).
Last release:
Emittery is a simple, modern async event emitter for Node.js and the browser, designed so listeners run asynchronously (next microtask) to keep code non-blocking. It supports strongly typed events (TypeScript), async iteration with for await...of, cancellation via AbortSignal, lifecycle hooks (init and deinit), and debug logging. Useful for building event-driven code that needs Promise-based async behavior and clean subscription management.
Actively maintained: Yes, the repo shows recent work within the last year (latest upstream push on 2026-05-24, and tagged updates through 2026-03-04).
