    qxotica - tools for qooxdoo

    Tools for developing qooxdoo Web apps

    Includes a package for the Lazarus IDE that adds items to the File | New dialog. Selecting "qooxdoo JavaScript App" creates either a single-page or two-page master-detail qooxdoo app and a Lazarus project for managing and editing the app's JavaScript files. Selecting "qooxdoo JavaScript Page" adds a page to the app and to the Lazarus project. Can also "compile" (run generate.py) from within Lazarus - if a syntax error is detected, the code editor jumps to the JavaScript file and line where the error is located. Also includes full source code for the Unicodum demo app. This is a Unicode viewer consisting of a qooxdoo-based mobile client and a choice of Pascal (FCGI) or PHP server app.

    reactstrap

    reactstrap

    Simple React Bootstrap 5 components

    Reactstrap is currently compatible with Bootstrap 5.1. If you are using Bootstrap 4, you'll need to use Reactstrap v8. This library contains React Bootstrap components that favor composition and control. The library does not depend on jQuery or Bootstrap javascript. However, Poppers.js via react-popper is relied upon for advanced positioning of content like Tooltips, Popovers, and auto-flipping Dropdowns. There are a few core concepts to understand in order to make the most out of this library. Your content is expected to be composed via props.children rather than using named props to pass in Components. Attributes in this library are used to pass in-state, conveniently apply modifier classes, enable advanced functionality (like tether), or automatically include non-content-based elements.

    sakura

    sakura

    A minimal CSS framework/theme

    Just drop in sakura.css to any webpage and go from ugly looking 1900s website to a pretty modern website in literally 0 seconds. Easy to customize and build on top of sakura. Sakura supports extremely easy theming support using variables for duotone color scheming. Comes with several existing themes, and can be found in the CSS folder of this repository. Don't want to develop using sakura, but instead want to use it on websites with outdated 90's design (i.e. no CSS)? Quick prototyping, especially when working on backend sites and can't yet be bothered to fidget with CSS/HTML. Building a quick (but pretty) site/blog for your best friend or aunt! No need to remember tons of different class names for every other CSS framework. Works amazingly with markdown generated HTML pages (eliminates the need of hacks like including .img img-responsive in markdown-parser generated <img></img> tags).

    scriptaculous

    scriptaculous

    script.aculo.us is an open-source JavaScript framework

    scriptaculous is an open-source JavaScript framework for visual effects and interface behaviors in classic Ajax-era web applications. It builds on the Prototype JavaScript library and adds higher-level tools for animation, drag-and-drop behavior, controls, sliders, and interface enhancements. The project was created for websites that wanted richer user interaction before modern frontend frameworks became common. Developers could include Prototype and the script.aculo.us files, then use the provided modules to create dynamic page behavior. The repository includes source files, library builds, tests, examples, and installation guidance. It is most useful today as a legacy frontend dependency, a historical reference, or a maintenance tool for older Prototype-based applications.

    slim.js

    slim.js

    Fast & Robust Front-End Micro-framework based on modern standards

    slim.js makes interactivity creation a joy. Design any view for you application and the fast implementation of slim.js will take care of the reactivity. Any property change or event triggered in your app will efficiently update your DOM only when it needs to. It is expressive as you would like it to be: anything typed inside handlebars will execute as-is, causing efficient re-render only of the affected nodes. The slim.js core is tiny (less than 3kB gzipped) - It scans the HTML and looks for handlebars syntax. Anything inside is your code. It just executes it as functions in your component's scope, only when your properties change, and only for the relevant ones. slim.js is extensible. You can add your own custom directives to the registry with a simple API, or add global plugins that execute's your code on every step of a component's lifecycle.
