svelte-awaitable-dialog

Js library for opening custom modal windows/dialogs/drawers and getting data from them inside a regular js function. With its help, you can get rid of adding additional variables to track the opening of a dialog and storing data from it, as well as adding the layout components themselves.

Installation

npm install svelte-awaitable-dialog

Or with Yarn

yarn add svelte-awaitable-dialog

Usage

For example, like that you can get user confirmation by the simplest dialog:

SimpleDialog.svelte

<script>
  import { closeDialog, resolveDialog } from 'svelte-awaitable-dialog'
  import { onMount } from 'svelte'

  export let title = 'Confirm action?'
  let dialog
  onMount(() => {
    dialog && dialog.showModal()
  })
</script>
<dialog bind:this={dialog} on:close={closeDialog}>
  <h1>{title}</h1>
  <button on:click={resolveDialog}>Confirm</button>
  <button on:click={closeDialog}>Cancel</button>
</dialog>

+page.svelte

<script lang="ts">
  import { AwaitableDialog, openDialog } from 'svelte-awaitable-dialog'
  import SimpleDialog from './components/dialog_examples/SimpleDialog.svelte'
  async function confirm() {
    // Here you can pass any custom Svelte component and its props
    openDialog(SimpleDialog, { title: 'Confirm action?' })
      .then(() => console.log('CONFIRMED'))
  }
</script>

<button on:click={confirm}>Run action</button>
<!--  You need only one AwaitableDialog on your page (for SvelteKit it's a good idea to add it to root +layout.svelte)-->
<AwaitableDialog/>

Also there's opportunity to return data from dialog as promise result by passing data object to resolveDialog function. Check REPL for example.
