axe-core
Accessibility engine for automated Web UI testing
Axe is an accessibility testing engine for websites and other HTML-based user interfaces. It's fast, secure, lightweight, and was built to seamlessly integrate with any existing test environment so you can automate accessibility testing alongside your regular functional testing. Axe-core has different types of rules, for WCAG 2.0 and 2.1 on level A and AA, as well as a number of best practices that help you identify common accessibility practices like ensuring every page has an h1 heading, and to help you avoid "gotchas" in ARIA like where an ARIA attribute you used will get ignored. With axe-core, you can find on average 57% of WCAG issues automatically. Additionally, axe-core will return elements as "incomplete" where axe-core could not be certain, and manual review is needed. -

bors-ng
A merge bot for GitHub Pull Requests
bors-ng is a GitHub merge bot that enforces an “evergreen” main branch by queueing approved pull requests, testing them together on a staging branch, and only advancing main with the exact, passing commit set. Instead of maintainers repeatedly rebasing and merging one PR at a time, bors-ng batches r+-ed PRs, triggers your existing CI (e.g., GitHub Actions), and merges automatically when the batch is green. If a batch fails, it bisects the batch into smaller runs to isolate the culprit, landing the good PRs and kicking only the failing one(s) back for fixes. The bot is implemented as a GitHub App and works alongside—rather than replacing—your CI by reporting commit statuses/checks and acting on PR comments like bors r+ or bors try. It provides a dashboard to watch queue progress, uses separate staging/trying branches for merge/test cycles, and supports both public GitHub and GitHub Enterprise endpoints. -

cookie
HTTP server cookie parsing and serialization
Basic HTTP cookie parser and serializer for HTTP servers. This is a Node.js module available through the npm registry. Installation is done using the npm install command. Parse an HTTP Cookie header string and return an object of all cookie name-value pairs. The str argument is the string representing a Cookie header value and options is an optional object containing additional parsing options. Specifies a function that will be used to decode a cookie's value. Since the value of a cookie has a limited character set (and must be a simple string), this function can be used to decode a previously-encoded cookie value into a JavaScript string or other object. The default function is the global decodeURIComponent, which will decode any URL-encoded sequences into their byte representations. -

crawler
Collection of JS reverse engineering examples for web scraping study
crawler is a collection of web scraping and JavaScript reverse engineering examples designed for learning how modern websites protect their data and how those protections can be analyzed. It contains many case studies that demonstrate how to analyze and replicate request parameters, cookies, and encryption logic used by real websites. Each directory in the project focuses on a specific target service or scenario, showing how browser network requests and JavaScript code can be studied to reproduce API calls programmatically. Many examples illustrate techniques such as debugging scripts, intercepting requests, analyzing encrypted parameters, and understanding authentication flows. crawler also explores common anti-scraping defenses and demonstrates how developers can examine them through debugging tools and reverse engineering techniques. -

cross-env
Cross platform setting of environment scripts
Run scripts that set and use environment variables across platforms. Cross-env still works well, but is in maintenance mode. No new features will be added, only serious and common-case bugs will be fixed, and it will only be kept up-to-date with Node.js over time. Most Windows command prompts will choke when you set environment variables with NODE_ENV=production like that. (The exception is Bash on Windows, which uses native Bash.) Similarly, there's a difference in how windows and POSIX commands utilize environment variables. -

css-spinner
Small, elegant pure css spinner for ajax or loading animation
Open source CSS loading animations dedicated for speed, simplicity & dev-friendly. Loading.io's CSS spinner uses CSS Animation, which is wildly supported by all modern browsers such as Google Chrome and Mozilla Firefox. However, the Microsoft Internet Explorer version earlier than 10 doesn't support CSS Animation. To support older IE, you have to use a GIF format image. Choose one from loading.io's online spinner gallery and you can customize a unique loader GIF with our icon editor easily. Some older browsers need prefixes like '-WebKit-' to use CSS Animation. To minimize file size, we omitted all vendor prefixes in loaders' CSS, but you can customize this by building CSS from the source. We also provide stylus and pug source files for better integrating these spinners into your project. Find corresponding stylus and pug files for your desired spinners under src/ folders. -

css3-
CSS3 implements various 3D && 3D planetary animation effects
css3- is an extensive collection of CSS3 demonstrations and visual experiments that highlight modern styling capabilities through practical, hands-on examples. The repository focuses on helping front-end developers understand how to implement sophisticated UI effects using native browser features rather than heavy external libraries. It covers a wide range of topics including animations, layout tricks, transitions, and creative visual compositions. The project is structured as a reference-style showcase where each example isolates a specific technique, making it easy to study and adapt into real projects. Its educational value lies in revealing non-obvious CSS behaviors and encouraging deeper mastery of the styling layer. Overall, css3- serves as a comprehensive learning and inspiration resource for developers seeking to master advanced CSS3 techniques. -

cssnano
A modular minifier, built on top of the PostCSS ecosystem
cssnano is a modern, modular compression tool written on top of the PostCSS ecosystem, which allows us to use a lot of powerful features in order to compact CSS appropriately. Our preset system allow you to load cssnano in a different configuration depending on your needs; the default preset performs safe transforms, whereas the advanced preset performs more aggressive transforms that are safe only when your site meets the requirements; but regardless of the preset you choose, we handle more than whitespace transforms! Optimizations range from compressing colors & removing comments, to discarding overridden at-rules, normalizing unicode-range descriptors, even mangling gradient parameters for a smaller output value! In addition, where it's made sense for a transform, we've added Browserslist to provide different output depending on the browsers that you support. -

darwin-skill
Autoresearch-inspired autonomous skill optimization for Claude Code
darwin-skill is an experimental framework designed to automatically improve AI agent “skills” through iterative evaluation and optimization loops inspired by machine learning training processes. Instead of treating prompts or skill definitions as static assets, the system applies a continuous improvement cycle that evaluates performance, proposes changes, tests outcomes, and either retains or reverts modifications. The framework introduces a scoring system across multiple dimensions, enabling quantitative assessment of skill quality and ensuring that only improvements are preserved over time. It incorporates a “ratchet mechanism” similar to version control workflows, guaranteeing that performance never degrades as iterations progress. The system also separates the agents responsible for editing and evaluating skills to avoid bias, which improves the reliability of optimization results. -

date-fns
Modern JavaScript date utility library
date-fns is a modern JavaScript date utility library that offers the most comprehensive toolset for manipulating JavaScript dates in a browser and Node.js. It’s complete and yet simple, because the API is unambiguous, with just one approach to a problem. It’s highly reliable and consistent, always respecting timezones and DST. And it’s also modular, so you don’t have to bloat your project with unnecessary functionality. date-fns supports TypeScript and Flow, and is supported by an amazing community with dozens of locales. -

dialog-polyfill.js
Polyfill for the HTML dialog element
dialog-polyfill.js is a polyfill for dialog and form method="dialog". Dialog is an element for a popup box in a web page, including a modal option that will make the rest of the page inert during use. This could be useful to block a user's interaction until they give you a response, or to confirm an action. See the HTML spec. This polyfill works on modern versions of all major browsers. It also supports IE9 and above. It can work when used inside Shadow DOM, but it's not recommended. The major limitation of the polyfill is that dialogs should not have parents that create a stacking context. The easiest way to solve this is to move your dialog element to be a child of body. -

electron-webpack-dashboard
Electron Desktop GUI for Webpack Dashboard
The original webpack-dashboard, was fun and people seemed to like it. Unless they were on Windows, or used a weird terminal set up, or if they just wanted more. Making things work across a variety of different terminal environments is pretty rough. Also, a web GUI provides some unique UI possibilities that weren't there with the term display. The original dashboard felt like working at NASA. 50 years ago. I hope this dashboard feels like working at NASA today. Or at Westworld. Or like the beginning of Westworld at least. To receive a complete analysis of your bundle, including modules, assets, and problems, you will need to make sure your project is using Webpack Dashboard Plugin 1.0 or higher. Simply hit save on a project running webpack-dev-server, or run your build task that builds with webpack and providing you have configured your project as shown above, you should see the dashboard start to display data. -

eslint-plugin-jsx-a11y
Static AST checker for a11y rules on JSX elements
Static AST checker for accessibility rules on JSX elements. This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. Enforce all elements that require alternative text have meaningful information to relay back to the end user. -

eslint-plugin-unicorn
More than 100 powerful ESLint rules
More than 100 powerful ESLint rules. You might want to check out XO, which includes this plugin. Each rule has emojis denoting if it belongs to the recommended configuration if some problems reported by the rule are automatically fixable by the --fix command line option, or if some problems reported by the rule are manually fixable by editor suggestions. Use a preset config or configure each rules in package.json. -

eslint-plugin-vue
ESLint plugin for Vue.js
ESLint plugin for Vue.js. This plugin allows us to check the template and script of .vue files with ESLint, as well as Vue code in .js files. This plugin supports the basic syntax of Vue.js 3.2, script setup, and CSS variable injection, but the ref sugar, an experimental feature of Vue.js 3.2, is not yet supported. If you have issues with these, please also refer to the FAQ. If you can't find a solution, search for the issue and if the issue doesn't exist, open a new issue. Be aware that depending on the code samples you write in tests, the RuleTester parser property must be set accordingly (this can be done on a test-by-test basis). The default JavaScript parser must be replaced because Vue.js single file components are not plain JavaScript, but a custom file format. vue-eslint-parser is a replacement parser that generates an enhanced AST with nodes that represent specific parts of the template syntax, as well as the contents of the script tag. -

fancyBox
jQuery lightbox script for displaying images, videos and more
Fancybox saves you time and helps to easily create beautiful, modern overlay windows containing images, iframes, videos or any kind of HTML content. This is the 4th generation of Fancybox and brings lots of fresh features. Both Carousel and Panzoom components are used under the hood and help ensure a best-in-class user experience. In addition, they are easy to integrate with each other. Touch and mobile optimized with swipe, drag and pinch-to-zoom gestures. Highly customizable with configuration options, Sass and CSS variables. There are two main styles of coding when using Fancybox. Each of these styles has advantages and disadvantages, and you can combine the two. You can choose any CSS selector here to attach click handler to the currently selected set of elements as well as all future matching elements. -

fast-json-stringify
2x faster than JSON.stringify()
fast-json-stringify is significantly faster than JSON.stringify() for small payloads. Its performance advantage shrinks as your payload grows. It pairs well with flatstr, which triggers a V8 optimization that improves performance when eventually converting the string to a Buffer. -

find-my-way
A crazy fast HTTP router
A crazy fast HTTP router, internally uses a highly performant Radix Tree (aka compact Prefix Tree), supports route params, wildcards, and it's framework is independent. You can set a custom length for parameters in parametric (standard, regex and multi) routes by using maxParamLength option, the default value is 100 characters. If you are using a regex-based route, find-my-way will throw an error if detects potentially catastrophic exponential-time regular expressions (internally uses safe-regex2). According to RFC3986, find-my-way is case-sensitive by default. You can disable this by setting the caseSensitive option to false: in that case, all paths will be matched as lowercase, but the route parameters or wildcards will maintain their original letter casing. -

frontend-interview
The strongest front-end interview guide in the universe
This is a review summary project about preparing for front-end interviews that I have summarized, and the project is updated from time to time. This is not only a strategy for job interviews, but also a collection of front-end ers to examine themselves and achieve breakthroughs. I hope that through this guide, everyone can open up their own lines of Ren and Du, and go further on the road to the front. This warehouse uses a large number of diagrams to convey knowledge. The so-called picture is worth a thousand words. I hope that this kind of graphic expression will make it easier for you to remember some abstract and incomprehensible concepts. "Graphic Front End" is my subtitle to it. Interviewing is a very subjective and difficult thing. Just because you don't pass the interview doesn't mean you're unqualified, just like passing the interview doesn't mean you're qualified. As a candidate, you are usually given 45 minutes to demonstrate your skills. -

fx
Command-line tool and terminal JSON viewer
fx can work in two modes, cli and interactive. To start interactive mode pipe any JSON into fx. One of the frequent operations is mapping some function on an array. You can pass any number of anonymous functions for reducing JSON. fx provides a function save which will save everything in place and return saved object. This function can be only used with filename as first argument to fx command. Create .fxrc file in $HOME directory, and require any packages or define global functions. To be able require global modules make sure you have correct NODE_PATH env variable. If you need output other than JSON (for example arguments for xargs), do not return anything from the reducer. undefined value is printed into stderr by default. Sometimes it is necessary to omit some messages in JSON stream, or select only specified log messages. For this purpose, fx has special helpers select/filter, pass function into it to select/filter JSON messages. -

gtop
System monitoring dashboard for terminal
gtop is a tool that helps you monitor your systems through a dashboard user interface, and it is optimized to monitor and visualize terminals. gtop requirements are to have Node.js version 8 or higher. It supports Linux, OSX, and Windows (with partial support). You need to assign host net and pid to access the metrics in the host machine. Start gtop with the gtop command. To stop gtop use q, or ctrl+c in most shell environments. You can sort the process table by pressing 'p' for Process Id, 'c' for CPU usage, and 'm' for Memory usage. If you see question marks or other different characters, try to run it with the environment variables provided in the documentation. gtop is released under the MIT license.
