Cheerio
Implementation of core jQuery designed for the server
Fast, flexible & lean implementation of core jQuery designed specifically for the server. Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API. Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Cheerio wraps around parse5 parser and can optionally use @FB55's forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If your use case requires any of this functionality, you should consider projects like Puppeteer or JSDom. -

Everything Claude Code
Complete Claude Code configuration collection
Everything Claude Code is a community-driven collection of Claude Code skills, workflows, and examples that accelerate the adoption of Anthropic’s Claude models for real-world developer tasks, ranging from project scaffolding to code generation and testing automation. The repository curates reproducible templates that demonstrate how Claude Code agents can participate in end-to-end developer journeys such as building new features, adhering to coding standards, generating documentation, and automating refactor patterns. It also includes example orchestrations that showcase multi-step agent workflows, letting developers see how to compose small, discrete agent capabilities into productive, cohesive sequences. Because it is designed to be modular, individuals and teams can pull in only the skills they need, combine them with custom logic, or share their own extensions with the community. -

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! -

Grunt
A JavaScript task runner
Why use a task runner? In one word, automation. The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes. After you've configured it through a Gruntfile, a task runner can do most of that mundane work for you and your team with basically zero effort. The Grunt ecosystem is huge and it's growing every day. With literally hundreds of plugins to choose from, you can use Grunt to automate just about anything with a minimum of effort. If someone hasn't already built what you need, authoring and publishing your own Grunt plugin to npm is a breeze. Many of the tasks you need are already available as Grunt Plugins, and new plugins are published every day. While installing grunt is simple, it's slightly more involved to get it running on your project. -

Highlight.js
JavaScript syntax highlighter with language auto-detection
Highlight.js is a syntax highlighter written in JavaScript. It works in the browser as well as on the server. It can work with pretty much any markup, doesn’t depend on any other frameworks, and has automatic language detection. Highlight.js supports over 180 languages in the core library. There are also 3rd party language definitions available to support even more languages. We strongly recommend <pre><code> wrapping for code blocks. It's quite semantic and "just works" out of the box with zero fiddling. It is possible to use other HTML elements (or combos), but you may need to pay special attention to preserving linebreaks. You can run highlighting inside a web worker to avoid freezing the browser window while dealing with very big chunks of code. -

Jasmine
A JavaScript Testing Framework
Jasmine is a behavior-driven JavaScript development framework for running both browser and Node.js tests. It’s been tested to work on most versions of popular browsers including Safari, Chrome, Firefox, and Internet Explorer. Jasmine does not rely on any other JavaScript frameworks, browsers or DOM, making it suitable for websites, Node.js projects, or just about anywhere that JavaScript can run. Jasmine has everything you need out of the box to test your code, yet retains a low overhead and absolutely no external dependencies. This means, of course, that it is fast. It has a clean, obvious syntax that makes writing tests a breeze. -

Learning Prompt
Free prompt engineering online course
Learning-Prompt is a curated repository of prompts, techniques, and instructional patterns designed to help people construct better prompts for AI systems, including generation, reasoning, and debugging tasks. It collects examples of effective prompt formats, chains of thought, strategy scaffolds, and comparative methods that help yield consistent, high-quality results. The project also includes meta-guidance: reflections on prompt failures, tips for prompt tuning, ways to mitigate model bias or misinterpretation, and how to adapt prompts for different AI capabilities. Because prompt design is a skill under continuous iteration, the repo encourages contributions of new prompt recipes, evaluations, and domain-specific adaptations. It’s intended for educators, developers, and prompt engineers who want a living toolkit rather than static advice. Over time it serves as both a reference and playground for emergent prompt techniques. -
