Jasny Bootstrap
The missing components for your favorite front-end framework
Jasny Bootstrap is an extension to vanilla Bootstrap, adding a number of features and components. The aim of Jasny Bootstrap is to provide all the required features for building highly interactive web applications for desktop and mobile. As of version 3.1.0 Jasny Bootstrap is no longer bundled with vanilla Bootstrap. You should load vanilla Bootstrap's CSS before this extension. Jasny Bootstrap has a few easy ways to quickly get started, each one appealing to a different skill level and use case. Read through to see what suits your particular needs. The fastest way to get Jasny Bootstrap is to download the compiled and minified versions of our CSS and JavaScript. No documentation or original source files are included. Get the latest Jasny Bootstrap LESS and JavaScript source code by downloading it directly from GitHub. Visit us on GitHub to clone or fork the Jasny Bootstrap project. -

Jasonette
Native App over HTTP, on iOS
Jasonette offers a different, easy way to let you create an iOS app, and that’s by using a single JSON, loaded over HTTP, local file, or anywhere. That’s right, with nothing but JSON, you can create your own native iOS app. It fetches a JSON markup from a server, and self-constructs into the native app in real time. It’s 100% native, 100% JSON, no hard-coding required. It’s the easiest and fastest way to build your app, as it only takes minutes and needs no programming experience. You can make changes to your live app and see these changes instantly. Jasonette comes with all the essential native APIs and components, and if there’s a specific feature you’re looking for, you can easily extend Jasonette. You could even integrate Jasonette with your existing iOS project, so you don’t have to switch to a completely different way of programming, just let Jasonette handle a part of your app. -

JavaScript & Node.js Testing
Comprehensive and exhaustive JavaScript & Node.js testing
This project compiles practical advice for testing JavaScript applications across the stack, emphasizing clarity, speed, and reliability over dogma. It distinguishes between different kinds of tests—unit, integration, end-to-end—and shows when each is appropriate given time and risk constraints. The guide focuses on removing flakiness by isolating side effects, controlling randomness, and stabilizing async code paths. It also demonstrates test design techniques like arranging test data, using expressive assertions, and structuring test suites for readability and discoverability. Tooling agnosticism is a theme: patterns are illustrated with popular tools but written to survive framework churn. The end goal is a test suite that acts as living documentation while catching regressions quickly and deterministically. -

JavaScript Array Explorer
A resource to figure out what JavaScript array method would be best
Array Explorer is an educational web-based resource created by Sarah Drasner to help developers understand and select the appropriate JavaScript array method (like map, filter, reduce, find, etc.) when they’re stuck wondering “which one should I use?” Instead of diving into endless docs, you can use the interactive tool to specify what you’re trying to accomplish—e.g., “remove items,” “transform items,” “find something,” “aggregate results”—then see which methods match and get live code examples. The tool provides visual examples, explanations of method semantics, and code snippets you can copy into your own project. Because many JavaScript learners struggle with which array method to choose or misuse them, this resource offers an approachable way to learn by doing and exploring rather than memorizing. The front-end is friendly and responsive, with filtering UI that lets you narrow based on the kind of task you’re performing. -

JavaScript Load Image
Load images provided as File or Blob objects or via URL
JavaScript-Load-Image is a client-side image loading and processing library that focuses on turning File/Blob objects or remote URLs into HTML <img> or <canvas> elements, optionally transformed in the process. It is often used in upload flows where images need to be previewed, resized, rotated, or cropped before being sent to a server, reducing bandwidth and improving user experience. The library can interpret image metadata, including Exif and IPTC tags, and can extract embedded thumbnails when present, which is handy for building fast image pickers or galleries. One of its key capabilities is correcting Exif Orientation, so photos taken on mobile devices appear upright without additional server-side processing. It also offers the option to preserve or restore image headers when resizing, which helps retain metadata or orientation information in the re-encoded image. -

JavaScript MD5
Compatible with server-side environments like node.js
JavaScript-MD5 is a small, dependency-free implementation of the MD5 hashing algorithm written entirely in JavaScript, designed to run consistently across browsers, Node.js, and popular module loaders. It allows you to generate MD5 hashes from strings, arrays, ArrayBuffers, and other binary-like data types, making it useful for checksums, fingerprinting, and simple integrity checks on the client or server. The library is exposed as a plain function, so usage is as simple as calling md5(value) and receiving the 32-character hexadecimal hash. It supports multiple packaging formats, including UMD, making it easy to drop into legacy codebases as well as modern bundlers like webpack or Browserify. A comprehensive test suite and demo page are provided to validate behavior across platforms and edge cases. -

JavaScript Stack from Scratch
Tutorial to build a modern JavaScript stack
This is a straight-to-the-point guide to assembling a JavaScript stack. It requires some general programming knowledge, and JavaScript basics. It focuses on wiring tools together and giving you the simplest possible example for each tool. You can see this tutorial as a way to write your own boilerplate from scratch. Since the goal of this tutorial is to assemble various tools, I do not go into details about how these tools work individually. Refer to their documentation or find other tutorials if you want to acquire deeper knowledge in them. You don't need to use this entire stack if you build a simple web page with a few JS interactions of course (a combination of Browserify/Webpack + Babel + jQuery is enough to be able to write ES6 code in different files), but if you want to build a web app that scales, and need help setting things up, this tutorial will work great for you.
