hypel

hypel creates dom elements with vanilla javascript

div('#app', [
  h1('hello everybody'),
  ul('#bestest-menu', items.map(item => (
    li('#item-'+item.id, attrs(item.id), item.title))))
])

hypel is used with vdom implementations such as react or inferno. A compact example,

import hypel from 'hypel'
import { h } from 'inferno-hyperscript'
import { render } from 'inferno'

const { div, span, a } = hypel(h)

render(
  div('#container.two.classes', {
    // note: syntax for classNames, attributes and other
    // details differ depending upon virtual-dom library
    on: { click: () => console.log('go') }
  }, [
    span('.bold', 'This is bold'), ' and this is just normal text ',
    a('.link', { props: { href: "/foo" } }, 'now go places!')
  ]), document.getElementById('container'))
// <div class="two classes" id="container">
//   <span class="bold">This is bold</span> and this is just
//   normal text <a class="link">now go places!</a>
// </div>

hypel includes a namespace feature that renders className and id attibutes from namespace values as below. Import hypelns or hypelnssvg to use this feature,

import { hypelns } from 'hypel'
import { h } from 'inferno-hyperscript'

const { div, h1, ul, li } = hypelns(h)
const ns = { uid: '123' } // use any key namea
const items = [
  { id: 'item1', title: 'item 1!'},
  { id: 'item2', title: 'item 2!'}]

div(ns, '#:uid-app', [
  h1(ns, 'hello everybody'),
    ul(ns, '#:uid-bestest-menu', items.map(item => (
      li(ns, '#:uid-item-'+item.id, item.title))))
  ])
)
// <div id="123-app">
//   <h1>hello everybody</h1>
//   <ul id="123-bestest-menu">
//     <li id="123-item-item1">item 1!</li>
//     <li id="123-item-item2">item 2!</li>
//   </ul>
// </div>

Credit

Credit to Ossi Hanhinen and his hyperscript-helpers package. This package was created from hyperscrpt-helpers when that package was no longer maintaind and incompatible with the esm-bundling strategy I used.

This package adds to the original hyperscript-helpers in these ways,

• exports an esm module and declares "module" type in the package.json,
• exports a single file,
• uses node-native test-runner,
• examples demonstrate more vdom packages; snabbdom, inferno and react,
• adds a namespacing feature,
• adds github ci for tests,
• smaller package size
