attodom

attodom

yet another experimental small DOM component library, < 1kb

• Why • API • License

Why

• experimenting on different APIs to find the minimal helpers required for
  • dynamic nodes, elements and lists
  • one way data flow from root component to child nodes

Features

• multiple dynamic lists within the same parent
• svg and namespace support
• no virtual DOM, all operations are done on actual nodes
• synthetic events available
• < 1kb gzip, no dependencies
• Designed for phones and/or older browsers:
  • very low memory requirement
  • no transpilation required

Limitations

• strictly DOM element creation and manipulations (no router, no store)

API

Elements and Nodes (hyperscript)

• el(tagName [, attributes [,children ]] ): HTMLElement
• svg(tagName [, attributes [,children ]] ): SVGElement

where

• attributes: {name: value, update: updateFunction}
• children: {number|string|Node|Array<children>}
• updateFunction: (this:Node, value:* [, key:* [, object:*]]): void

Synthetic Events

Synthetic events are used when the first letter of the event name is capitalised

• regular event: el('h1', {onclick: handler}, 'click me')
• synthetic event: el('h1', {onClick: handler}, 'click me')

Lists

• list(parent, factory, options): List

where

• factory: function(value:* [, key:* [, object:*]]): Node
• options.before: Node
• options.after: Node
• options.key: string | function([*], [number], [Array]): string
• List: {parent, before, after, factory, key, children, update}
• list.update: function([*], [number], [Array]): List

list creates a List object with an update method that can update the parent children to match a data Array

var ol = el('ol'),
    bullets = list(ol, (v, i) => el('li', i + ':' + v))
bullets.update(['a', 'b'])
// <ol><li>1:a</li><li>2:b</li></ol>
