<script>
import { listen, idle, onIdle } from 'svelte-idle'

// Run listen on component Initialization
listen()

// Run code when the user idle via a callback...

</script>

User is idle: {$idle}

listen

The listen method accepts an optional object (type: SvelteIdleListenConfig). The following values can be defined:

timer

• type: number
• defines: amount of milliseconds until idle is true
• default: 60_000 (10 minutes)

cycle

• type: number
• defines: amount of milliseconds before each idle-check
• default: 200

Example:

import { listen } from 'svelte-idle'

listen({
    timer: 60_000,
    cycle: 500
})

idle

A readable store that reflects the current idle-state.

onIdle

Callback which will be fired everytime idle becomes true. Returns a method for clearing the listener.

Example:

import { onMoumt } from 'svelte'
import { onIdle } from 'svelte-idle'

onMount(() => {
    const unsub = onIdle(() => console.log('User is idle!'))
    return unsub
})
