THANKS
Give thanks to the open source maintainers you depend on
THANKS is a small command-line tool that helps developers discover which open-source maintainers behind their npm dependencies are accepting donations. It is built around a simple idea: projects benefit from countless unpaid maintainer hours, so users should have an easy way to support the people who keep those projects alive. Instead of forcing teams to research every dependency manually, thanks scans the current project and surfaces donation opportunities directly from the terminal. It can be run instantly with npx or installed globally for repeated use across projects. The project also invites maintainers to add themselves to its donation list through pull requests, making it community-driven. It is best suited for JavaScript and Node.js developers who want to make open-source funding more visible and actionable. -

Text Typesetting
Concise guide to better typography and formatting practices
Text-Typesetting is a concise guide to better typography and formatting practices for technical writing. It collects rules of spacing, punctuation, emphasis, and layout that improve readability, especially in documents mixing multiple languages or code. The repository focuses on consistent micro-typography—such as when to use non-breaking spaces, how to place punctuation around quotes, and how to format lists and headings. Examples show the before/after impact of small adjustments, making the guidance practical rather than theoretical. Because the recommendations are tooling-agnostic, they apply to Markdown, HTML, slides, and printed PDFs alike. It’s a handy checklist for authors who want cleaner, more professional documents without becoming typography experts. -

URI.js
Javascript URL mutation library
URI.js is a javascript library for working with URLs. It offers a "jQuery-style" API (Fluent Interface, Method Chaining) to read and write all regular components and a number of convenience methods like .directory() and .authority(). URI.js offers simple, yet powerful ways of working with query string, has a number of URI-normalization functions and converts relative/absolute paths. While URI.js provides a jQuery plugin. URI.js itself does not rely on jQuery. You don't need jQuery to use URI.js. URI.js (without plugins) has a gzipped weight of about 7KB, if you include all extensions you end up at about 13KB. So unless you need second level domain support and use URI templates, we suggest you don't include them in your build. Clone the URI.js repository or use a package manager to get URI.js into your project. See the build tool or use Google Closure Compiler. -

UglifyJS
JavaScript parser library for NodeJS
UglifyJS-old is the original version of UglifyJS, a JavaScript toolkit for parsing, compressing, mangling, and beautifying source code. Its parser converts JavaScript into an abstract syntax tree that can be inspected or manipulated programmatically. The code generator can rebuild readable JavaScript or remove unnecessary whitespace to reduce file size. Its mangler shortens variable names while accounting for scope, globals, eval calls, and with statements. Compression routines simplify expressions, combine declarations, transform conditionals, and remove unreachable code. The package also includes a command-line interface and remains primarily a legacy version superseded by the rewritten UglifyJS2 project. -

Underscore.js
JavaScript's utility belt
Underscore.js is a JavaScript utility-library created by Jeremy Ashkenas that provides a broad set of functions for working with arrays, objects, functions, and other data types — essentially a “utility belt” for functional programming in JS. Instead of extending built-in objects or modifying prototypes, Underscore provides its helpers in a single _ namespace, enabling cross-browser support and consistent behaviour across environments. It offers map/filter/reduce, deep-cloning, templating, object traversal, function binding, and more, which makes it easier to write concise, expressive code rather than verbose loops and conditional logic. Many other libraries and frameworks (including Backbone) historically depended on or partnered with Underscore for their utility functions. Even though ES6+ and Lodash have overshadowed some of its role, Underscore remains influential and educational for how to design utility APIs. -
