    Plupload

    Plupload

    JavaScript API for building file uploaders

    At its core Plupload is visually flat and you can customize it however you like. We are using HTML5 APIs. Always. Plupload is based on multi-runtime pollyfills for XMLHttpRequest L2, File and Image APIs. So when there's no HTML5 available in the browser, we emulate it ourselves. Files not only can be picked from browse dialog, but also can be dropped directly from the desktop. In some browsers, mostly in those based on WebKit, it is possible to drag and drop whole folders. Since we emulate as much of HTML5 as possible, we are able (among other things) to provide access to raw file data, even in such environments that do not normally support it. One of the biggest benefits of this is that we can display the thumbnails instantly, right as you select the images in the dialog or drag&drop them from the desktop. We slice the files in chunks and send them out one by one. You can then safely collect them on the server and combine into original file.

    PreprocesssorWizard

    PreprocesssorWizard

    WYSIWIG conditional compilation preprocessor for Java etc.

    A WYSIWYG Conditional Compilation Preprocessor for Java, Perl, C, C++, Basic, PowerShell, C#, Javascript, and other programming languages. Many C and C++ developers rely heavily on the C preprocessor, and lament the lack of a preprocessor in Java, scripting languages, and other programming languages. The principal objection to a preprocessor is that it makes one's code difficult to read. This is indeed true for the C preprocessor. It is sometimes difficult to determine which lines of code are active and which are not. Being WYSIWYG, the PreprocessorWizard multi-language WYSIWIG preprocessor resolves the problem of code being difficult to read and allows one preprocessing syntax for all languages. It is easy to use as a standalone application and it can be easily integrated with almost any IDE.

    Ramda

    Ramda

    A practical functional library for JavaScript programmers

    Ramda is a practical functional library for JavaScript programmers. There are already several excellent libraries with a functional flavor. Typically, they are meant to be general-purpose toolkits, suitable for working in multiple paradigms. Ramda has a more focused goal. We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data. The primary distinguishing features of Ramda are: Ramda emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code. Ramda functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters. The parameters to Ramda functions are arranged to make it convenient for currying. The data to be operated on is generally supplied last.

    Ratchet

    Ratchet

    Build mobile apps with simple HTML, CSS, and JavaScript components

    Ratchet is designed to respond to touch events from a mobile device. Enable touch event emulation in Chrome (found in the overrides tab in the web inspector preferences). Use a JavaScript library like fingerblast.js to emulate touch events (ideally only loaded from desktop devices). Ratchet is downloadable in two forms, within which you'll find directories and files, logically grouping common resources and providing both compiled and minified variations. The most basic form of Ratchet is the grouping of the precompiled files for quick drop-in usage in nearly any web project. We provide compiled CSS and JS (ratchet.*), as well as compiled and minified CSS and JS (ratchet.min.*). The Ratchicon fonts are included, as are the Android and iOS platform themes. The Ratchet source code download includes the precompiled CSS, JavaScript, and font assets. Provides design patterns that serve as basic building blocks.

    React Redux Starter Kit

    React Redux Starter Kit

    Get started with React, Redux, and React-Router

    This starter kit is designed to get you up and running with a bunch of awesome front-end technologies. The primary goal of this project is to provide a stable foundation upon which to build modern web appliications. Its purpose is not to dictate your project structure or to demonstrate a complete real-world application, but to provide a set of tools intended to make front-end development robust, easy, and, most importantly, fun. The project structure presented in this boilerplate is fractal, where functionality is grouped primarily by feature rather than file type. This structure is only meant to serve as a guide, it is by no means prescriptive. That said, it aims to represent generally accepted guidelines and patterns for building scalable applications. Hot reloading is enabled by default when the application is running in development mode (yarn start). This feature is implemented with webpack's Hot Module Replacement capabilities.

    Screwdriver API

    Screwdriver API

    An open source build platform designed for continuous delivery

    Screwdriver is an open-source build platform designed for Continuous Delivery. Screwdriver began as a hack for simplified interfacing with Jenkins at Yahoo in 2012. As the volume of builds increased, it became clear that Jenkins was not stable or feasible to use at the scale we were running builds. In 2016, we rebuilt Screwdriver from scratch in open source with our best coding practices and CICD goals in mind. Screwdriver is executor and SCM-agnostic, meaning you can choose whichever plugin better suits your need or build your own. It's completely free and open-source, and our team is actively maintaining the code. Screwdriver is a self-contained, pluggable service to help you build, test, and continuously deliver software using the latest containerization technologies. We support an expanding list of source code services, execution engines, and databases so Screwdriver can work in your ecosystem.

    Snowpack

    Snowpack

    ESM-powered frontend build tool

    Snowpack is a frontend build tool built around native JavaScript ES modules. It was designed to make development faster by avoiding the traditional full-bundle step during local work. The dev server can start quickly and reflect browser changes almost instantly. Snowpack supports modern web project needs such as TypeScript, JSX, CSS Modules, plugins, and framework integrations. It can also connect with bundlers for optimized production builds when a project needs minification, code splitting, or compatibility output. The repository is no longer actively maintained, so it is best understood as an important legacy tool that influenced the modern unbundled development workflow.
