    Twemoji

    Twemoji

    Simple library that provides standard Unicode emoji for all platforms

    Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope.

    wa-sqlite

    wa-sqlite

    WebAssembly SQLite with support for browser storage extensions

    wa-sqlite is a WebAssembly build of SQLite that enables developers to run a fully functional relational database engine inside web browsers or other JavaScript environments. Unlike traditional SQLite builds, this project emphasizes extensibility by allowing developers to implement custom virtual file systems entirely in JavaScript, which enables flexible storage backends such as IndexedDB or the Origin Private File System. This design allows applications to persist data locally in a browser while maintaining the familiar SQL interface and behavior of SQLite. The project supports both synchronous and asynchronous execution models, accommodating different performance and architectural needs, including asynchronous APIs required for certain browser storage systems. It also includes example implementations of various storage strategies, demonstrating how developers can tailor persistence mechanisms for specific use cases.

    whatsapp-web.js

    whatsapp-web.js

    WhatsApp library for NodeJS that connects through the browser app

    A WhatsApp client library for NodeJS that connects through the WhatsApp Web browser app. Programmatically control WhatsApp whether you're running user or business accounts. It uses Puppeteer to run a real instance of Whatsapp Web to avoid getting blocked. Programmatically control WhatsApp whether you're running user or business accounts. Whatsapp-web.js connects to an official version of WhatsApp Web under the hood, reducing ban risks. The object-oriented approach makes it easy to get running quickly. Since whatsapp-web.js works by running WhatsApp Web in the background and automating its interaction, you'll need to authorize the client by scanning a QR code from WhatsApp on your phone. After scanning this QR code, the client should be authorized and you should see a Client is ready! message being printed out.

    window.fetch polyfill

    window.fetch polyfill

    A window.fetch JavaScript polyfill

    window.fetch polyfill is a JavaScript polyfill that provides the standard window.fetch API and related interfaces in older web browsers. Importing the package patches the browser environment only when native support is missing or incomplete. It supports common workflows for retrieving HTML or JSON, inspecting response metadata, posting forms or JSON, and uploading files through FormData. Requests return Promises and follow the behavior defined by the Fetch specification, including its handling of HTTP error statuses. Abortable requests are supported when compatible AbortController and AbortSignal implementations are available. The package is designed for browsers rather than Node.js and has little effect in modern browsers with native fetch support.

    Midscene

    Midscene

    Vision-based AI framework for cross-platform UI automation tasks

    Midscene.js is an open source AI-driven UI automation framework designed to control user interfaces across multiple platforms using natural language instructions. Instead of relying on traditional selectors, DOM structures, or accessibility attributes, it uses a vision-first approach where screenshots are analyzed by visual-language models to identify interface elements and perform actions. It allows developers to automate interactions on web applications, desktop software, and mobile devices without needing platform-specific automation logic. Developers can describe tasks such as clicking buttons, filling forms, or extracting information, and the system interprets these commands to interact with the interface accordingly. Midscene.js includes SDKs, scripting options, and integration capabilities that allow automation workflows to be written in JavaScript, TypeScript, or YAML-based scripts. Midscene also provides debugging and development tools.

    OWASP Juice Shop

    OWASP Juice Shop

    Probably the most modern and sophisticated insecure web application

    It can be used in security trainings, awareness demos, CTFs and as a guinea pig for security tools! Juice Shop encompasses vulnerabilities from the entire OWASP Top Ten along with many other security flaws found in real-world applications! Juice Shop is written in Node.js, Express and Angular. It was the first application written entirely in JavaScript listed in the OWASP VWA Directory. The application contains a vast number of hacking challenges of varying difficulty where the user is supposed to exploit the underlying vulnerabilities. The hacking progress is tracked on a scoreboard. Finding this scoreboard is actually one of the (easy) challenges! Apart from the hacker and awareness training use case, pentesting proxies or security scanners can use Juice Shop as a “guinea pig”-application to check how well their tools cope with JavaScript-heavy application frontends and REST APIs.

    OpenWhip

    OpenWhip

    Optimize interaction with AI coding assistants

    OpenWhip is a desktop utility built as a cross-platform Node.js application that humorously gamifies interaction with AI coding assistants by simulating a “whip” tool to interrupt and motivate them during long or stalled operations. The application runs as a lightweight system tray program and overlays a visual whip animation on the screen when activated, creating an interactive and slightly absurd interface for user engagement. Its core functionality is surprisingly practical beneath the joke: when triggered, it sends a keyboard interrupt signal (Ctrl+C) to halt the current AI process, effectively giving developers a quick way to stop unresponsive or slow-running tasks. In addition to the interrupt, the tool also delivers randomized “encouraging” or humorous messages, blending utility with personality and making the experience more entertaining.

    Serialize JavaScript

    Serialize JavaScript to a superset of JSON

    Serialize JavaScript to a superset of JSON that includes regular expressions, dates and functions. The code in this package began its life as an internal module to express-state. To expand its usefulness, it now lives as serialize-javascript — an independent package on npm. A primary feature of this package is to serialize code to a string of literal JavaScript which can be embedded in an HTML document by adding it as the contents of the script element. In order to make this safe, HTML characters and JavaScript line terminators are escaped automatically.

What's considered "image-like" differs depending on whether it is being run from the browser or through NodeJS.
