Basic

const pureHandlers = new PureHandlers()

pureHandlers.addEventListener(window, 'scroll', (event) => {
  // your awesome logic
})

// Destroy all listeners
pureHandlers.destroy()

Targeted Destroyer

const destroyer = pureHandlers.setInterval(() => {
  // your awesome logs, for example
}, 1000)

// Destroy only this listener
destroyer()

Your own Destroyers

const listener = new MyAwesomeListener()

pureHandlers.addDestroyer(() => listener.myUnsubscribe())

// Destroy all listeners
pureHandlers.destroy()

Your own targeted Destroyer

const listener = new MyAwesomeListener()

const destroyer = pureHandlers.addDestroyer(() => listener.myUnsubscribe())

// Destroy only this listener
// and remove the destroyer from pureHandlers' list of destroyers
destroyer()

React

import PureHandlers from 'pure-handlers'

export default function MyOwnAwesomeClock() {
  const [second, setSecond] = useState(0)

  useEffect(() => {
    const pureHandlers = new PureHandlers()

    pureHandlers.setInterval(() => {
      setSecond((oldSecond) => oldSecond + 1)
    }, 1000)

    return () => pureHandlers.destroy()
  }, [])

  return <span>Current second: {second}</span>
}

React Hook

With auto-destroy on unmount.

import { usePureHandlers } from 'pure-handlers/react'

export default function MyOwnAwesomeClock() {
  const [second, setSecond] = useState(0)
  const pureHandlers = usePureHandlers()

  useEffect(() => {
    pureHandlers.setInterval(() => {
      setSecond((oldSecond) => oldSecond + 1)
    }, 1000)
  }, [])

  return <span>Current second: {second}</span>
}

Browser

Or move the file to your libs directory.

<script src="/node_modules/pure-handlers/dist/browser/pure-handlers.browser.min.js"></script>
<script>
  // PureHandlers is available globally now
  var pureHandlers = new PureHandlers()
</script>
