hyper(HTML)

A Fast & Light Virtual DOM Alternative available for NodeJS and NativeScript too.

V2 Highlights

Following most important changes in version 2:

• fully rewritten, and consumable, as ES2015 Module
• usable via CDN as bundled global hyperHTML variable
• restructured in modules, utilities, helpers, and commented all over for simplified contribution
• removed .escape and .adopt, either useless or unstable. hyperHTML.adopt will be implemented as module a part
• added support for objects as style attribute, fully compatible with Preact implementation
• improved performance in numerous ways
• custom elements V0 and V1 are now fully, and properly, supported through document.importNode and/or regular cloneNode tested against common polyfills
• back to 4.5K thanks to rollup and its ability to merge all the things together like it was already in V1

Documentation

A proper documentation full of examples can be found in viperhtml.js.org.

Basic Example

The easiest way to describe hyperHTML is through an example.

// this is hyperHTML
function tick(render) {
  render`
    <div>
      <h1>Hello, world!</h1>
      <h2>It is ${new Date().toLocaleTimeString()}.</h2>
    </div>
  `;
}
setInterval(tick, 1000,
  hyperHTML(document.getElementById('root'))
);

Features

• Zero dependencies, no polyfills needed, and it fits in about 4.5KB (minified + brotli)
• Uses directly native DOM, no virtual DOM involved
• Designed for template literals, a templating feature built in to JS
• Compatible with plain DOM elements and plain JS data structures
• Also compatible with Babel transpiled output, hence suitable for every browser you can think of

Compatibility

IE9+ , iOS8+ , Android 4+ and every modern Mobile or Desktop Browser. You can verify directly through the following links:

• 100% code coverage for browsers natively compatible with string literals
• 100% code coverage for IE9+ and browsers that need transpiled code
