Key features:

• error reporting
• virtual DOM tree
• create
  • create using prototype class
  • support multiple level prototypes
  • DOM caching
• state
• binding
  • with other component
  • with state
• update
  • set (recreate)
  • only iterate with diff
• events

Getting started

To install all dependencies and run dev server, run:

yarn && yarn start

Examples

Initialization:

import DOM from '@rackai/domql'

DOM.create({ text: 'Rendered' })

Attributes:

var link = {
  tag: 'a',
  class: 'menu link',
  attr: {
    href: '#'
  }
}

var img = {
  tag: 'img',
  class: 'avatar',
  attr: {
    src: '...'
  }
}

Reusing:

var Link = {
  tag: 'a'
}

var ListItem = {
  proto: Link,
  class: 'ui link',
  attr: {
    href: '#'
  }
}

var menu = {
  childProto: ListItem,
  home: 'Home',
  text: 'About'
}

var header = {
  logo: {},
  menu
}

Array Support:

var navItems = ['Home', 'About', 'FAQ', 'Contact']

var menu = {
  proto: ListItem,
  ...navItems
}

Update:

var val = {
  text: 0
}

var Increment = {
  tag: 'button',
  text: 'Increment',
  on: {
    click: (e) => {
      val.update({ text: val.text++ })
    }
  }
}

API

Properties

To specify your own property per Element, set the function inside define property like:

var User = {
  define: {
    username: param => param.toUpperCase()
  },
  text: element => element.username
}

var Contact = {
  proto: User,
  username: 'nikoloza'
}

Methods

Events

All native DOM events are supported and can be specified inside on parameter. Additionally, init and render can be also invoked. All events except these two receive event object as a first parameter, following the element object itself.

Reserved keywords

key
tag
node
proto
on
class
text
data
style
attr
update
set
define

Anything except these keywords will create a new nested child element. The easier method to specify HTML tag is to use related nodeName as a key, for example:

var layout = { // this will be <div>
  header: {}, // will create <header>
  aside: {}, // will create <aside>
  main: { // will create <main>
    childProto: {
      article: { // will create <article>
        title: {}, // will create <div>
        description: {}, // will create <div>
        _rating: {} // will create <div class="rating">
      }
    }
  },
  footer: {} //  will create <footer>
}
