Open
Open stuff like URLs, files, executables. Cross-platform
Open is a cross-platform Node.js package for launching URLs, files, directories, and executables from command-line tools or scripts. It uses the operating system's default application unless developers request a specific program. Applications can also pass command-line arguments to the program being opened. The package works across macOS, Windows, Linux, and Windows Subsystem for Linux environments. On Linux, it includes an up-to-date xdg-open implementation, while WSL support can translate paths for Windows applications. Open uses process spawning rather than shell execution, which avoids several problems associated with command-string execution. It is distributed as a native ESM package and expects developers to sanitize untrusted values before opening them. -

P-Limit
Run multiple promise-returning & async functions
P-Limit is a JavaScript utility for controlling how many promise-returning or asynchronous functions execute at the same time. Developers create a limiter with a chosen concurrency level and run tasks through it instead of launching every operation immediately. The library works in both Node.js and modern browsers. It exposes counts for currently active and waiting tasks so applications can inspect workload state. Pending work can be cleared, and an optional setting can reject discarded promises with an AbortError. The concurrency limit can also be changed after creation. Additional helpers support concurrency-limited mapping and creating individual functions that automatically manage their own simultaneous executions. -

Pify
Promisify a callback-style function
Pify is a JavaScript package for converting callback-based functions into promise-returning equivalents. It can promisify a single function or process the methods of an entire module automatically. This makes older Node.js callback APIs easier to use with async and await syntax. Developers can selectively include or exclude methods through names or regular-expression patterns. The library can return multiple callback values as an array when an API provides more than one successful result. It also supports APIs that do not follow the conventional error-first callback pattern. Additional options allow the module's main function to remain untouched and permit use of a custom Promise implementation. -

fastq
Fast, in memory work queue
fastq is a high-performance in-memory work queue for JavaScript and Node.js applications. It runs tasks through a worker function while enforcing a configurable concurrency limit. Both traditional callback workers and Promise-based async workers are supported. Tasks can be added to either the front or back of the queue depending on scheduling needs. Processing can be paused, resumed, emptied, or terminated while exposing the current queue length and idle state. Hooks report conditions such as drain, saturation, empty queues, and task errors. TypeScript definitions are included, and the package is designed to provide queue management with very little performance overhead. -

screenfull
Wrapper for cross-browser usage of the JavaScript Fullscreen API
Screenfull is a lightweight JavaScript library that simplifies use of the browser Fullscreen API across supported browsers. It lets developers place an entire page or an individual element into fullscreen mode through a consistent interface. The library smooths over browser-specific API differences that would otherwise require extra compatibility code. Applications can request fullscreen, exit it, toggle it, inspect the active fullscreen element, and check whether fullscreen is available. It also exposes fullscreen change and error events for reactive interfaces. Screenfull is distributed as an ESM package, is only about 0.7 kB when gzipped, and is considered feature complete. It does not support fullscreen operation on iPhone. -

Stylus for Chrome
Stylus - Userstyles Manager
Stylus is a fork of Stylish for Chrome, also compatible with Firefox as a WebExtension. "Stylus" is a fork of the popular Stylish extension which can be used to restyle the web. Not "ish", but "us", as in "us" the actual users. Stylus is a fork of Stylish that is based on the source code of version 1.5.2, which was the most up-to-date version before the original developer stopped working on the project. The objective in creating Stylus was to remove any and all analytics, and return to a more user-friendly UI. We recognize that the ability to transfer your database from Stylish is important, so this is the one and only feature we've implemented from the new version. Two different optional code validators with user-configurable rules: CSSLint and Stylelint. Both validators use Web Worker API to run in a separate background thread inside the editor tab without blocking your interaction with the code. -

Dexie.js
A Minimalistic Wrapper for IndexedDB
Dexie was written to be straightforward and easy to learn. If you've ever had to work with native IndexedDB then you'll certainly appreciate Dexie's concise API. What good is any development tool without great documentation? Dexie is thoroughly explained, and examples are available to help you on your way. Dexie has near-native performance. Its bulk operations utilize an often-overlooked feature in IndexedDB, ignoring success callbacks when possible. Offline databases are groovy! But without keeping the database in sync with a server, you're missing a great deal. Dexie.js solves these limitations and provides a neat database API. Dexie.js aims to be the first-hand choice of a IDB Wrapper Library due to its well thought-through API design, robust error handling, extendability, change tracking awareness and its extended KeyRange support (case insensitive search, set matches and or operations). -

SwissGL
SwissGL is a minimalistic wrapper on top of WebGL2 JS API
SwissGL is a compact JavaScript library that provides a streamlined abstraction layer over the WebGL2 API, designed to minimize boilerplate when building GPU-accelerated graphics, simulations, and procedural visualizations. Acting as a "Swiss Army knife" for WebGL2, it simplifies shader, texture, and framebuffer management into a single, expressive interface that enables developers to write complex GPU workflows in just a few lines of code. The library centers around one main function that unifies rendering and compute operations, allowing the creation of particle systems, GPGPU effects, and real-time simulations entirely on the GPU. Despite its simplicity and small size (under 1000 lines of code), SwissGL demonstrates remarkable flexibility, from basic visual experiments to complex multi-pass rendering pipelines. It’s also designed as an exploration of minimalist graphics API design, serving as an early experimental step toward the upcoming WebGPU era.
