compone v0.2.0

compone

Lifecycle Callbacks for any HTML Element

<div c1="my-compone">Hello!</div>

import { define } from "compone"

define("my-compone", function (host) {
  console.log("connected", host.textContent)
})

Mixins

Add more functionality to your compone with mixins

onDisconnect

import { define } from "compone"
import { _onDisconnect } from "compone/mixins"

define("my-compone", function (host) {
  const onDisconnect = _onDisconnect(host)

  function clickHandler(event) {
    console.log("click", event)
  }

  host.addEventListener(clickHandler)

  onDisconnect(function () {
    host.removeEventListener(clickHandler)
  })
})

on

onDisconnect is a good place to clean up event listeners. While this is a common pattern, there's an own mixin for that.

import { define } from "compone"
import { _on } from "compone/mixins"

define("my-compone", function (host) {
  const on = _on(host)

  on(host, "click", function (event) {
    console.log("click", event)
  })
})

qs & qsa

Another common task is selecting child elements

import { define } from "compone"
import { _qs, _qsa } from "compone/mixins"

define("my-compone", function (host) {
  const qs = _qs(host)
  const qsa = _qsa(host)

  const child = qs(".child")
  const children = qsa(".child")
})
