svelte-eventbus

Simple eventbus realization based on internal Svelte's tools only.

Use when you need handle events from deeply-nested child components without events forwarding.

Features

• You can set event listeners on Eventbus component and catch any event created with createEventbusDispatcher in any child component.

• Events are isolated inside of Eventbus component instance. You can have more than one Eventbus in the parent component. Each will listen events from it's child components only.

• If you have several nested Eventbus components, events will bubble through them while needed event listener will be occurred.

Usage example:

Parent - App.svelte

<script>
    import {Eventbus} from 'svelte-eventbus';
    import Child from './Child.svelte';

    let totalclicks = 0;
</script>

<p>Total clicks: {totalclicks}</p>

<Eventbus on:button_click={()=>totalclicks++}>
    <!-- There can be childs in any nest level-->
    <Child />
</Eventbus>

Nested - Child.svelte

<script>
    import {createEventbusDispatcher} from 'svelte-eventbus';
    const dispatch = createEventbusDispatcher();
</script>

<button on:click={()=>dispatch('button_click')}>Click</button>
