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. -

jQuery Validation Plugin
jQuery Validation Plugin library sources
The jQuery Validation Plugin provides drop-in validation for your existing forms, while making all kinds of customizations to fit your application really easy. This jQuery plugin makes simple clientside form validation easy, whilst still offering plenty of customization options. It makes a good choice if you’re building something new from scratch, but also when you’re trying to integrate something into an existing application with lots of existing markup. The plugin comes bundled with a useful set of validation methods, including URL and email validation, while providing an API to write your own methods. All bundled methods come with default error messages in english and translations into 37 other languages. The plugin was initially written and maintained by Jörn Zaefferer, a member of the jQuery team, lead developer on the jQuery UI team and maintainer of QUnit. It was started back in the early days of jQuery in 2006, and updated and improved since then. -

update-notifier
Update notifications for your CLI app
update-notifier is a Node.js package for informing command-line application users when a newer package version is available. It is designed to make update messages noticeable without delaying application startup or repeatedly interrupting users. Version checks run asynchronously in a separate unreferenced child process and are persisted for later runs. Developers can define how frequently checks occur and inspect information such as the installed version, latest version, package name, and update type. Notification messages and Boxen-based presentation options can be customized. Users can disable notifications through configuration, an environment variable, or a command-line flag. Checks are automatically skipped in environments such as continuous integration and unit tests. -

DevTools Detect
Detect if DevTools is open and its orientation
DevTools Detect is a browser-focused JavaScript package for estimating whether a browser's developer tools are currently open. It also reports whether detected DevTools are positioned vertically or horizontally. Applications can inspect the current state directly or listen for a custom event when the state changes. The package supports Chrome, Safari, Firefox, and Opera developer tools. It can be used for interface behaviors such as pausing graphics or displaying additional debugging information while tools are open. However, browser changes have made detection unreliable, and the project explicitly warns about false positives and limitations with undocked tools. The repository was archived in May 2026 and is now read-only. -

Electron Context Menu
Context menu for your Electron app
Electron Context Menu is a JavaScript package that adds configurable right-click menus to Electron applications. It provides common native-style actions that Electron developers would otherwise need to implement manually. Built-in behavior includes cut, copy, paste, text lookup, web search, link copying, image actions, video actions, and spellchecking-related commands. An Inspect Element option can automatically appear during development for easier debugging. Developers can add, remove, reorder, rename, or transform menu actions and can target specific windows or views. The package operates from Electron's main process and can apply menus to existing and newly created windows. Its extensible API helps applications provide richer context-sensitive interactions with less custom menu code. -

Gifted Form
One React-Native form component to rule them all
React Native Gifted Form is a form-building component library for React Native applications. It provides reusable widgets for text inputs, text areas, selects, switches, dates, countries, modal subforms, hidden values, notices, and submit actions. Validation rules can be attached to individual fields and executed when a form is submitted. Forms with the same name can share stored values through GiftedFormManager. External state management is also supported for selected widgets through controlled values and change callbacks. Google Places integration is available through a dedicated location widget. Developers can create additional widgets by implementing the library’s widget mixin, making the form system extensible beyond its built-in controls. -

Node.js Telegram Bot API
Telegram Bot API for NodeJS
TelegramBot is an EventEmitter that emits several events. Message, received a new incoming Message of any kind. Depending on the properties of the Message, one of these events may ALSO be emitted, text, audio, document, photo, sticker, video, voice, contact, location, new_chat_members, left_chat_member, new_chat_title, new_chat_photo, delete_chat_photo, group_chat_created, game, pinned_message, poll, dice, migrate_from_chat_id, migrate_to_chat_id, channel_chat_created, supergroup_chat_created, successful_payment, invoice, video_note, etc. Its much better to listen a specific event rather than on message in order to stay safe from the content. Bot must be enabled on inline mode for receive some messages.T elegram only supports HTTPS connections to WebHooks. Therefore, in order to set a WebHook, you will need a SSL certificate. The library makes it easy to get started sending files. By default, you may provide a file-path and the library will handle reading it for you. -

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. -
16
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. -
17
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. -
18
Prettier
Opinionated Code Formatter
Prettier is an open source, opinionated code formatter that basically takes all the original styling of your code and enforces a consistent code style through parsing and reprinting following its own rules. It takes the maximum line length into account, wrapping code if needed. Prettier makes writing code in one consistent style automatic, painless and so much easier. No need to spend so much time, effort and mental energy discussing styles or formatting your code. Simply press save and your code is formatted. Prettier supports several languages including JavaScript, TypeScript, JSON, CSS, HTML and more. It also integrates with most editors (Atom, Visual Studio, Vim, Espresso and more). -

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. -
