    Cloudflare-Socks5

    Cloudflare-Socks5

    CF-workers/pages proxy script: supports Vless-ws (tls) and Trojan-ws

    Cloudflare-Socks5 is a proxy deployment toolkit designed to leverage Cloudflare Workers and Pages to create flexible, censorship-resistant proxy nodes using protocols such as VLESS and Trojan. The project provides scripts that enable users to deploy proxy services locally without relying on external subscription providers, improving privacy and control over configuration data. It supports multiple transport modes including WebSocket with TLS, as well as optional encrypted handshake mechanisms like ECH-TLS, standard TLS, or even non-TLS configurations to adapt to different network restrictions. The system is designed with accessibility in mind, offering simplified setup processes that allow users to deploy nodes with minimal configuration, often requiring only a UUID or password. It also includes tools for generating optimized Cloudflare IP selections and supports multiple node formats for compatibility with clients like Clash and sing-box.

    Engine.IO

    Engine.IO

    Transport-based cross-browser bi-directional communication layer

    In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client. Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect. Scale to multiple servers and send events to all connected clients with ease. Socket.IO is a library that enables real-time, bidirectional and event-based communication between the browser and the server. There are also several client implementation in other languages, which are maintained by the community. The client will try to establish a WebSocket connection if possible, and will fall back on HTTP long polling if not. WebSocket is a communication protocol which provides a full-duplex and low-latency channel between the server and the browser.

    Exifr

    Exifr

    The fastest and most versatile JS EXIF reading library

    Exifr is a fast and very versatile JavaScript EXIF reading library that works everywhere, parses everything and handles just about anything you throw at it. It can handle any input: buffers, url, <img> tag and more; .jpg, .tif, and .heic files; and TIFF (EXIF, GPS, etc.), XMP, ICC, IPTC, JFIF segments. It skips parsing tags you don’t need, and reads only the first few bytes. There’s no need to read the whole file to see if there’s an EXIF file in it, or extract all the data when you just need a few tags. Instead of reading byte by byte from start to finish, Exifr jumps through the file structure from pointer to pointer, making it extremely fast and efficient!

    MIT License

    MIT License

    Hosted MIT License with details controlled through this repo

    The MIT License repository is a simple GitHub project that hosts the full text of the MIT License and provides a stable reference for developers who want to include permissive licensing details in their work. The MIT License itself is one of the most widely used open-source licenses because it allows reuse, modification, distribution, and even proprietary use, as long as copyright notices and license texts are preserved. This repository offers an easy way to copy the license text, understand its legal language, and see example usage in a context that is separate from any specific software project. It can also be useful for automated tooling and templates where a standard license file is needed across multiple repositories or as part of a code generation process. While not a software library or application, the repository serves an important role in open-source governance by centralizing a commonly adopted license with clear formatting.

    Moment.js

    Moment.js

    Parse, validate, manipulate, and display dates in javascript

    Moment is a JavaScript date and time library that simplifies parsing, formatting, arithmetic, and humanizing of dates. It supports many formats in input and output, internationalization (i18n), locale-based month/day names, relative time (for example, “3 days ago”), and chaining of operations (adding, subtracting, diffing). Developers often use it for calendar displays, scheduling, and manipulating times across time zones or daylight saving transitions. While it makes working with date strings convenient, moment maintains internal mutability, which has trade-offs with safety and chainability. Over time, newer alternatives with immutable and modular designs have emerged, but moment remains widely known and integrated in many legacy projects. Its comprehensive feature set and ease of use made it a standard for date-time handling in JavaScript for many years.

    NN-SVG

    NN-SVG

    Publication-ready NN-architecture schematics

    Illustrations of Neural Network architectures are often time-consuming to produce, and machine learning researchers all too often find themselves constructing these diagrams from scratch by hand. NN-SVG is a tool for creating Neural Network (NN) architecture drawings parametrically rather than manually. It also provides the ability to export those drawings to Scalable Vector Graphics (SVG) files, suitable for inclusion in academic papers or web pages. The tool provides the ability to generate figures of three kinds: classic Fully-Connected Neural Network (FCNN) figures, Convolutional Neural Network (CNN) figures of the sort introduced in the LeNet paper, and Deep Neural Network figures following the style introduced in the AlexNet paper. The former two are accomplished using the D3 javascript library and the latter with the javascript library Three.js. NN-SVG provides the ability to style the figure to the user's liking via many size, color, and layout parameters.

    PWA

    PWA

    (WIP) Universal PWA Builder

    PWA is a “universal, framework-agnostic PWA builder” developed by Luke Edwards (lukeed) that aims to let developers scaffold progressive web apps with minimal friction across different view frameworks or libraries. Unlike many CLI tools that target a specific framework (React, Vue, Svelte), this project intentionally tries to remain agnostic, supporting presets for Preact, React, Vue, Svelte and even vanilla JS, while offering all the PWA boilerplate you need (service workers, manifest, offline support) right out of the box. The project is designed for speed of setup: you run pwa init, choose your preset, then pwa build or pwa watch and you get a production-ready bundle with PWA features baked in. The README emphasizes that modern bundlers (Webpack, Rollup) and ecosystem maturity finally allow a universal CLI of this kind, whereas earlier attempts weren’t practical.

    Playwright CLI is the official command-line interface for Playwright, a powerful cross-browser automation and end-to-end testing framework that lets developers write and run tests reliably across Chromium, WebKit, and Firefox. The CLI provides an easy entry point for creating new test projects, running test suites, generating test traces, and debugging issues directly from the terminal. Developers can scaffold test files, record browser interactions as code, and run tests in headless or headed modes without needing a complex setup, dramatically reducing the barrier to writing robust UI tests. Playwright-CLI includes utilities for running tests in parallel across multiple devices, capturing screenshots and videos on failures, and outputting detailed reports that help diagnose flaky behavior or regressions. It also integrates with CI/CD pipelines, making it simple to automate testing as part of build and deployment workflows.
