  • Toasts have different types and apply any style you need;
  • Toasts appear and disappear by specifying optional timeout.

Installation & Usage

Toaster-JS is primarily ES6 module. Install it with NPM:

npm install toaster-js

Then, include it to your project:

import { Toast } from "toaster-js";
import "toaster-js/default.scss"; // Assuming CSS/SCSS loader is present
// Import styles from SCSS: @import "../node_modules/toaster-js/default.scss";
// Or just copy default styles to your project from node_modules/toaster-js/default.*css. 

new Toast("Welcome!");
new Toast("There is a lot of toasts!", Toast.TYPE_ERROR, Toast.TIME_NORMAL);

let element = document.createElement("div");
element.textContent = "You can pass any HTML elements to Toast. Clicking on this one deletes it!";
let newToast = new Toast(element, Toast.TYPE_MESSAGE);
element.addEventListener("click", () => newToast.delete()); // delete a toast on message click!

You can set up additional options if you need. See the API section below for more details.

import { configureToasts, deleteAllToasts } from "toaster-js";

    topOrigin: 0,
    deleteDelay: 300
deleteAllToasts(); // just deletes all toasts on the screen

If you need to load ES5 (UMD) module, use the following:

let Toast = require("toaster-js/umd.js");

If you need to include the module with a script tag (for example, for demos), use this:

<script type="text/javascript" src=""></script>
<link rel="stylesheet" href=""/>


  • toast = new Toast(content, type, timeout)
    • Toast.TIME_SHORT (2000 ms)
    • Toast.TIME_NORMAL (4000 ms)
    • Toast.TIME_LONG (8000 ms, default)
    • Toast.TYPE_INFO
    • Toast.TYPE_MESSAGE
    • Toast.TYPE_WARNING
    • Toast.TYPE_ERROR
    • Toast.TYPE_DONE
    • toast.delete() - Deletes this toast from the DOM.
  • configureToasts(options)
    • options.topOrigin = 0 - A number in pixels of toasts Y-axis origin (negative values move toasts up).
    • options.deleteDelay = 300 - A number representing delay in milliseconds. When toast is deleted, it stays in DOM for deleteDelay more milliseconds. Useful with CSS animations.
  • deleteAllToasts() - Deletes all toasts on the screen.
Toast(content, type, timeout)

Creates a new toast notification message on the screen. Pass a string content to specify the message text, type = Toast.TYPE_* to specify the type and timeout = Toast.TIME_* to specify the timeout. Timeout constants are the numbers of milliseconds for message to stay on screen. For example, new Toast("Baked!", Toast.TYPE_ERROR, 10000) message will stay on the screen for 10 seconds.

  • TIME_SHORT = 2 seconds
  • TIME_NORMAL = 4 seconds
  • TIME_LONG = 8 seconds
  • TYPE_INFO = "info"
  • TYPE_MESSAGE = "message"
  • TYPE_WARNING = "warning"
  • TYPE_ERROR = "error"
  • TYPE_DONE = "done"

When content is a valid DOM Element, it will be attached to the message's body directly, allowing you to customize toast however you want.


Allows to configure some options of the toast. The available optional options are listed below:

    topOrigin: -100, // [default=0] Y-axis origin of the messages.
    deleteDelay: 300 // time until the toast is completely removed from the DOM after deleting. 


Import default toast styles from node_modules/toaster-js/default.*css (CSS, SCSS are available).

To style the toast properly, consider that toast elements (for example, info toasts) have three states: empty state (when the toast attaches to the DOM), displayed state (when the toast is moved to its proper position), and deleted state, when the toast "fades out" from the DOM. You can control how much time the toast stays in deleted state until it disappears using deleteDelay option. States:

<div class="toast">           <div class="body info">...</div> </div>
<div class="toast displayed"> <div class="body info">...</div> </div>
<div class="toast deleted">   <div class="body info">...</div> </div>
