        component: DialogView,
        class: "dialog"
      },
      title: "Dialog title"
    })
  }>
  Show dialog
</button>
<Dialog /> <!-- dialog will be drawn by this component -->

<style>
  :global(.dialog) {
    transition: opacity 350ms ease-in-out;

UseDialog

It is often desired to automatically show a dialog at a given route, so that it can be accessed by URL, and the browser back button will hide the dialog.

The component UseDialog allows for a declarative way of controlling dialogs. It will be shown when a condition is met (such as the current route), and automatically hidden as soon as the condition is no longer met.

This component is functionally equal to React's UseDialog. It accepts the same props as useDialog.

Example:

<script>
  import { UseDialog } from 'dialogic-svelte';
  import { location } from 'svelte-spa-router'; // example routing library, here used to fetch the current route

  const dialogPath = '/profile/edit';
  const dialogReturnPath = '/profile';
  $: isMatchDialogPath = $location === dialogPath; // Update the match check whenever the route changes

  const useDialogProps = {
    dialogic: {
      component: EditProfileDialog,
      className: 'dialog',
    },
    title: 'Update your e-mail',
  };
</script>

<div class="page">
  <p>Contents</p>
  <UseDialog
    props={useDialogProps}
    isShow={isMatchDialogPath} />
</div>

To make the dialog content dynamic, make useDialogProps a reactive variable.

Assuming that currentEmail is reactive:

$: useDialogProps = {
  dialogic: {
    component: EditProfileDialog,
    className: 'dialog',
  },
  title: `Your e-mail: ${$currentEmail}`,
};

and add the reactive variable to the deps:

<UseDialog
  props={useDialogProps}
  isShow={isMatchDialogPath}
  deps={[$currentEmail]} />

UseNotification

The component UseNotification has the same functionality as UseDialog.
