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.

Prop	Type	Default	Description
title	string	-	Title of toast
description	string	-	Description/body of toast
remove	Function	-	Invoking remove method will remove the respective toast object from store/UI. e.g. toast1.remove()
update	Function	-	Invoke update method to update a specific toast values like title, description or duration etc. toast.update({ title; "Progress: 80%" })
onClick	Function	() => {}	You can provide onClick callback which will be invoked when toast will be clicked (except toast close icon/button)
onRemove	Function	() => {}	You can provide onRemove callback which will be invoked when toast will be auto removed or removed by clicking on cross icon/button.
component	Svelte Component	-	You can provide your own toast component to render toast for a specific toast object
placement	string	-	Set placement of current toast, it will override default placement set by ToastContainer
showProgress	boolean	-	If set to "true" and duration is greater than 0 then a timeout progress bar will be shown at the bottom of current toast. It will override default value set by ToastContainer.
theme	string	-	"dark" and "light" themes are implemented for builtin Toast components but in case of your own Toast component, you can implement or leave this feature. This will override default value set by ToastContainer if you are using builtin Toast components.
type	string	-	Four types of toasts are available i.e. success, info, error and warning. It will override toast type set by ToastContainer.
duration	number	-	Duration in milliseconds after which toast will be auto removed. If duration will be 0 or negative, toast will not be auto removed but user can click on cross icon to remove it. It will override duration specified by ToastContainer.

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()
