    DOMPurify

    DOMPurify

    XSS sanitizer for HTML, MathML and SVG

    A DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, SVG and MathML. It's also very simple to use and get started with. DOMPurify was started in February 2014 and, meanwhile, has reached version 2.3.0. DOMPurify is written in JavaScript and works in all modern browsers (Safari (10+), Opera (15+), Internet Explorer (10+), Edge, Firefox and Chrome - as well as almost anything else using Blink or WebKit). It doesn't break on MSIE6 or other legacy browsers. It either uses a fall-back or simply does nothing. Our automated tests cover 17 different browsers right now, more to come. We also cover Node.js v14.15.1, v15.4.0, running DOMPurify on jsdom. Older Node.js versions are known to work as well. DOMPurify is written by security people who have vast background in web attacks and XSS.

    Fastify

    Fastify

    Fast and low overhead web framework, for Node.js

    Fastify is a high-performance web framework for Node.js that focuses on minimal overhead and predictable extensibility. It pairs a declarative routing API with JSON Schema–driven validation and serialization, so requests are checked at the edge and responses are produced quickly. The framework’s plugin system uses encapsulation to isolate routes, decorators, and hooks, which keeps large codebases modular and avoids accidental cross-pollution. Built-in hooks (such as onRequest, preHandler, and onSend) and lightweight decorators make it easy to insert cross-cutting concerns like auth, caching, and metrics. Fastify ships with thoughtful defaults like structured logging via Pino and AJV for schema validation, and it has first-class TypeScript types. The result is a server stack that scales to high throughput while remaining easy to reason about in production.

    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.

    Retire.js

    Scanner detecting the use of JavaScript libraries

    There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP.
