elevator.js

Finally, a "back to top" button that behaves like a real elevator, by adding elevator music to quietly soothe the awkwardness that can ensue when being smoothly scrolled to the top of the screen.

This is very serious stuff, here's a demo!

Instructions

Elevator.js is a stand alone library (no jquery, or the likes) so usage is pretty straight forward. All styling of elements is up to you. Elevator.js only handles the audio management, and the scroll functionality!

JS

Elevator.js lives entirely within the js realm, which makes things fairly simple to use.

You'll need to create a new instance of Elevator, and pass it some audio elements.

<script>
// Elevator script included on the page, already.
window.onload = function() {
  var elevator = new Elevator({
    mainAudio: '/src/to/audio.mp3',
    endAudio: '/src/to/end-audio.mp3'
  });
}

A virtual DOM library with focus on simplicity, modularity, powerful features and performance.

Thanks to Browserstack for providing access to their great cross-browser testing tools.

Introduction

Virtual DOM is awesome. It allows us to express our application's view as a function of its state. But existing solutions were way way too bloated, too slow, lacked features, had an API biased towards OOP and/or lacked features I needed.

Snabbdom consists of an extremely simple, performant and extensible core that is only ≈ 200 SLOC. It offers a modular architecture with rich functionality for extensions through custom modules. To keep the core simple, all non-essential functionality is delegated to modules.

You can mold Snabbdom into whatever you desire! Pick, choose and customize the functionality you want. Alternatively you can just use the default extensions and get a virtual DOM library with high performance, small size and all the features listed below.

Background

In React, the whole tree rendering performance problem of the form is very obvious in the controlled mode. Especially for the scene of data linkage, it is easy to cause the page to be stuck. To solve this problem, we have distributed the management of the state of each form field, which significantly improves the performance of the form operations. At the same time, we deeply integrate the JSON Schema protocol to help you solve the problem of back-end driven form rendering quickly.

Features

• 🖼 Designable, You can quickly develop forms at low cost through Form Builder.
• 🚀 High performance, fields managed independently, rather rerender the whole tree.
• 💡 Integrated Alibaba Fusion and Ant Design components are guaranteed to work out of the box.
• 🎨 JSON Schema applied for BackEnd. JSchema applied for FrontEnd. Two paradigms can be converted to each other.
• 🏅 Side effects…
