panda-play-esm v1.8.2

Play

Play is a lightweight library for building Web Components.

To create a component, you just call gadget:

import {Gadget, bebop, shadow, template, events} from "panda-play"

mixin class extends Gadget, [

  tag "x-greeting"

  # bebop preset gives us VDOM + automatic rendering
  # shadow give us Shadow DOM support
  bebop, shadow

  template ({value}) -> "<h1>#{value}, World!</h1>"

  events
    h1:
      click: ({target}) -> @value = "Goodbye"

Features

• Fully encapsulated native Web Components
• Virtual DOM, with diff-based updates
• Selector-based event handlers instead of inline
• Arbitrary template functions—use template literals, JSX, Pug, …
• Or use VHTML and generate VDOM directly
• Observable properties generate change events and re-render
• Component-targetable CSS from client document
• Pipe operator to wire components together
• Delegation pattern—Gadgets are handles to DOM elements
• Mixin-based composition avoid fragile base class problem
