gremlins.js
Monkey testing library for web apps and Node.js
Gremlins.js is an open-source monkey testing library written in JavaScript. It unleashes a horde of undisciplined gremlins on a web app in order to check its robustness. We've modernized the code of Gremlins.js, our monkey testing library for frontend apps. It's now super easy to detect memory leaks in your JavaScript code. Gremlins.js comes with 5 types of undisciplined gremlins that will try to break your web application: the clicker, the form filler, the scroller, the typer and the toucher. You can also add custom gremlins easily. While gremlins try their best to destroy your app, another type of scripts called mogwais monitor the console errors and the number of frames by second to detect performance problems. Every action performed by the gremlins, and all the errors that might occur, are all logged! In version 2.0, we now use npm to publish the library and unpkg to serve it! -

A client-side JavaScript SDK for authenticating with OAuth2 (and OAuth1 with an OAuth proxy) web services and querying their REST APIs. HelloJS standardizes paths and responses to common APIs like Google Data Services, Facebook Graph and Windows Live Connect. It’s modular, so that list is growing. No more spaghetti code! Compiled source, which combines all of the modules, can be obtained from GitHub, and source files can be found in Source. The Bower package shall install the aforementioned "/src" and "/dist" directories. The "/src" directory provides individual modules which can be packaged as desired. If a network string is provided: A consent window to authenticate with that network will be initiated. Else if no network is provided a prompt to select one of the networks will open. A callback will be executed if the user authenticates and or cancels the authentication flow. -

iCSS
More than CSS
iCSS is a large curated repository of advanced CSS techniques, creative experiments, and deep dives into modern web animation and styling capabilities. Rather than being a traditional library, the project functions as an educational and inspirational knowledge base that explores unusual, powerful, or overlooked CSS features. The content covers topics such as layout tricks, animation patterns, visual effects, accessibility considerations, and emerging CSS standards. Materials are continuously updated and organized by category, helping frontend developers discover new approaches to solving UI and visual design challenges. The repository aims to broaden developers’ thinking about what can be achieved purely with CSS and native browser capabilities. Overall, iCSS serves as a high-value reference and inspiration hub for frontend engineers seeking to push the boundaries of modern CSS. -

iLib
The most comprehensive library of Javascript i18n classes available
Note: development has been moved over to github! Please see https://github.com/iLib-js/iLib "I18N" means way more than just translation. Other libraries claim to be an i18n solution when translation and string formatting is really all they offer. Yes, iLib has classes that do translation too, but there is also much, much more. From date formatting to name parsing to phone number handling to collation, iLib has classes that do it. And, it has the ability to support thousands of possible locales. Everything in iLib is written in pure JS with minimal platform dependencies, so it works the same way in many different environments and browsers, from Chrome to Opera to node to Qt/QML. Over 17K unit tests help to guarantee this. ILib is also the library of choice for enyo apps on webOS which ships on over 10 million LG SmartTVs in over 135 countries. Give it a try and see if it can work for your app too! -

iView Weapp
A set of high-quality WeChat applet UI component library
Use WeChat to scan and experience the example of small program components. Before you start using iView Weapp, you need to read the micro-channel applet custom components related documents. We have built-in examples of all components, you can scan the small program code experience on the right, or view it in WeChat developer tools. Then, the examplesdirectory can be opened in the micro-channel developer tools. We adopted a 24-grid system to divide the area into 24 equal parts, which can easily deal with most layout problems. Using the grid system for web page layout can make the page layout beautiful and comfortable. The grid contains 4 components: i-grid, i-grid-item, i-grid-icon, i-grid-label, among them, i-grid-icon and i-grid-label have customized styles by default, but These two components can also be eliminated in development. -

interview-ouch
Simple web snippets for interviews
interview-ouch is a cheeky, realistic collection of tough interview questions and scenarios that tend to “hurt” unprepared candidates. It’s meant to expose the gaps in typical interview prep by highlighting non-trivial, edge-case, or context-heavy questions. The repo covers programming, systems, and sometimes softer judgment questions that interviewers use to see how you think under pressure. Instead of focusing only on textbook algorithms, it nudges you toward understanding trade-offs, code quality, debugging, and real-world constraints. This makes it a good practice tool for senior or experienced candidates who won’t be impressed by just LeetCode-style prompts. It’s also helpful for interviewers who want to refresh their own question bank with more challenging material. -
