Getting Started

<script>
  import { toasts, ToastContainer, FlatToast, BootstrapToast }  from "svelte-toasts";

  const showToast = () => {
    const toast = toasts.add({
      title: 'Message title',
      description: 'Message body',
      duration: 10000, // 0 or negative to avoid auto-remove
      placement: 'bottom-right',
      type: 'info',
      theme: 'dark',
      placement: 'bottom-right',
      type: 'success',
      theme,
      onClick: () => {},
      onRemove: () => {},
      // component: BootstrapToast, // allows to override toast component/template per toast
    });

    // toast.remove()

  };
</script>

<main class="flex flex-col container items-center mt-10">
    <h1 class="text-lg block text-center">Svelte Toasts</h1>
  <button on:click={showToast}>Show Toast</button>
  <ToastContainer placement="bottom-right" let:data={data}>
    <FlatToast {data} /> <!-- Provider template for your toasts -->
  </ToastContainer>
</main>

Every toast object has following structure:

{
  title: "Welcome",
  description: "Thanks for trying svelte-toasts!",
  uid: 1615153277482,
  placement: "bottom-right",
  type: "success",
  theme: "dark",
  duration: 0,
  remove: () => { /* implementation */ },
  update: () => { /* implementation */ },
  onClick: () => { console.log("Toast clicked"); }
  onRemove: () => { console.log("Toast removed"); },
  // and whatever properties that you want to add when calling toasts.add(options)
}

Below is a detail description of every property.

Helper Methods

You can use helper functions to create toast with just message argument.

toasts.success('Message body here'); // just 1 argument

toasts.success('Message Title', 'Message body here'); // 2 arguments, title, description

toasts.success('Message Title', 'Message body here', { duration: 5000 }); // 3 arguments, title, description and all other options object

Similarly, toasts.info(), toasts.warning() and toasts.error()
