WTFJS
A list of funny and tricky JavaScript examples
WTFJS is a curated collection of JavaScript “gotchas” and puzzling examples that reveal surprising corners of the language. Each entry presents a small snippet, explains why the behavior occurs, and ties it back to the specification or engine rules. The repository covers coercion quirks, edge-case comparisons, floating-point oddities, prototype traps, and scoping pitfalls, among others. It’s designed as both a fun read and a serious learning aid, helping developers build an intuition for how JavaScript evaluates expressions. By highlighting common misconceptions, it encourages safer coding patterns and more reliable mental models. Teachers, interviewers, and learners use it to spark discussion and deepen understanding of JavaScript’s semantics. -

WebRTC Chrome Extensions
WebRTC chrome extensions for screen sharing, screen recording
Chrome Extensions is a collection of WebRTC-focused Chrome extension examples from Muaz Khan. It includes extensions for recording screens, sharing desktops, sharing application windows, capturing YouTube audio, and related browser media workflows. The repository is organized as a set of small extension projects rather than one single application. Developers can study the source code to understand Chrome extension permissions, desktop capture behavior, and WebRTC media integration. Some entries link to Chrome Web Store installs, while the repository itself provides the implementation code. It is useful as a practical reference for browser-based screen capture, media sharing, and extension-powered WebRTC experiments. -

body-parser
Node.js body parsing middleware
Node.js body parsing middleware. Parse incoming request bodies in a middleware before your handlers, available under the req.body property. As req.body's shape is based on user-controlled input, all properties and values in this object are untrusted and should be validated before trusting. For example, req.body.foo.toString() may fail in multiple ways, for example the foo property may not be there or may not be a string, and toString may not be a function and instead a string or other user input. The bodyParser object exposes various factories to create middlewares. All middlewares will populate the req.body property with the parsed body when the Content-Type request header matches the type option, or an empty object ({}) if there was no body to parse, the Content-Type was not matched, or an error occurred. -

bootstrap-select
The jQuery plugin that brings select elements into the 21st century
The jQuery plugin that brings select elements into the 21st century with intuitive multiselection, searching, and much more. Now with Bootstrap 4 support. Bootstrap-select requires jQuery v1.9.1+, Bootstrap’s dropdown.js component, and Bootstrap's CSS. If you're not already using Bootstrap in your project, a precompiled version of the Bootstrap v3.4.1 minimum requirements can be downloaded. If using bootstrap-select with Bootstrap v4+, you'll also need Popper.js. For all of Bootstrap v4's requirements, see Getting started. A precompiled version of the requirements will be made available in an upcoming release of bootstrap-select. Bootstrap 4 only works with bootstrap-select v1.13.0+. By default, bootstrap-select automatically detects the version of Bootstrap being used. However, there are some instances where the version detection won't work. -

cls-rtracer
CLS-based request id generation for Express, Fastify, Koa and Hapi
Express & Koa middlewares and Fastify & Hapi plugins for CLS-based request ID generation, batteries included. An out-of-the-box solution for adding request IDs into your logs. Check out this blog post that describes the rationale behind cls-rtracer. Automatically generates a UUID V1 value as the id for each request and stores it in AsyncLocalStorage. Optionally, if the request contains an X-Request-Id header, uses its value instead. Allows to obtain the generated request id anywhere in your routes later and use it for logging or any other purposes. -

documentation.js
Documentation for modern JavaScript
A documentation system so good, you'll actually write documentation. documentation.js has pluggable output formats: you can get raw documentation as JSON, beautiful, customizable HTML, or Markdown that fits perfectly into an API.md or README.md file in a GitHub repository. Demos, self-documentation as HTML, Markdown, JSON. documentation.js aims to cover all flavors of modern JavaScript. documentation.js works in your workflow, whether you just want a command-line utility that generates documentation from your code, you use Gulp to publish websites, or you're building a new system and want low-level JavaScript methods. Infers parameters, types, membership, and more. Write less documentation: let the computer write it for you. Integrates with GitHub to link directly from documentation to the code it refers to. -

edgetunnel
edgetunnel 2.0 VLESS/Trojan
edgetunnel is a modified version of a serverless tunnelling solution designed to run on platforms like Cloudflare Workers and Pages, enabling protocols such as VLESS and Trojan to be exposed through edge-functions rather than traditional servers. The project’s fork by cmliu emphasizes conversion of protocol configuration (especially VLESS) into subscription links, so that users can deploy and then generate “Clash” or “Sing-box” compatible subscription content easily. It provides a streamlined way to host proxy endpoints without managing a full server stack, instead leveraging the edge network of Cloudflare for distribution and potential performance. Because it runs at the edge, latency can be minimized and deployment complexity simplified; users supply configuration variables (host, port, UUID, path) and the script handles mapping to technical protocols and subscription formatting. -

fast-json-stringify
2x faster than JSON.stringify()
fast-json-stringify is significantly faster than JSON.stringify() for small payloads. Its performance advantage shrinks as your payload grows. It pairs well with flatstr, which triggers a V8 optimization that improves performance when eventually converting the string to a Buffer. -

goober
A less than 1KB css-in-js solution
As the subtitle notes, this is the smallest and fullest featured css-in-js solution out there. Weighing at 1KB and once bundled it's gonna be less due to tree-shake. goober does more with less! Since the code measure less in size, it's served, read and ran quicker. goober is built on the shoulders of well-established solutions. That means the API has been paved and we need to follow it. You'll find as, forwarded, CSS, keyframes, styled and so much more. Easily access your common sizes, colors, and anything really with the use of a theme. On the server, you can easily extract the CSS for the current state with extractCss. The initial thought of goober was a CSS-in-js solution at the cost of peanuts. Hence the peanuts emoji. By using goober, you are practically getting back space in size to build more of the needed features. -

The library allows developers to build automation workflows for media processing without directly interacting with command-line tools. It supports multiple output formats such as MP4 and MKV and includes compatibility across major operating systems. handbrake-js relies on an installed HandBrakeCLI binary and exposes its functionality through asynchronous JavaScript APIs. It is commonly used in backend services and automation pipelines that require reliable video conversion. Overall, it serves as a bridge between HandBrake’s capabilities and Node.js environments. -

iFrame Resizer
Keep same and cross domain iFrames sized to their content
Size cross domain iFrames to content with support for window/content resizing, and multiple iFrames. This library enables the automatic resizing of the height and width of both same and cross domain iFrames to fit their contained content. It provides a range of features to address the most common issues with using iFrames. Provides a range of page size calculation methods to support complex CSS layouts. Detects changes to the DOM that can cause the page to resize using MutationObserver. Detects events that can cause the page to resize (window resize, CSS animation and transition, orientation change and mouse events). Fixes in page links in iFrame and supports links between the iFrame and parent page. Works with ViewerJS to support PDF and ODF documents. The package contains two minified JavaScript files in the js folder. The first (iframeResizer.min.js) is for the page hosting the iFrames. -
