Toaster-JS

The simple vanilla JavaScript toast pop-up notifications module, which is fully CSS-customizable. The solution which "just works": add the module to your project and go further.

Supported by all major browsers. Safe to use with ReactJS and other virtual-dom frameworks.

Preview

See the demo here.

Features

• Fully CSS-customizable toast pop-ups for any design;
• No dependencies and < 1kb code;
• Configurable toasts type and timeout;
• Fully configurable toast content (HTML, custom elements, etc).

Installation & Usage

Toaster-JS is primarily the uncompiled ES6 module. Install it with npm:

npm install toaster-js

Then, include it to your project:

import { Toast } from "toaster-js"; // const { Toast } = require("toaster-js/umd.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. 
// Or draw your own styles! For instance, you can make toasts appear on the left by overwriting .toast { left: 0; right: auto; }

// Simple toast
new Toast("Welcome!");

// Typed toast (just a matter of CSS) with timeout
new Toast("There is a lot of toasts!", Toast.TYPE_ERROR, Toast.TIME_NORMAL);

// Custom toast content example (you can also add something like close buttons, etc)
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";

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

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

const { 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="https://unpkg.com/toaster-js/umd.js"></script>
<link rel="stylesheet" href="https://unpkg.com/toaster-js/default.css"/>

API

• 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.

configureToasts(options)

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

configureToasts({
    topOrigin: -100, // [default=0] Y-axis origin of the messages (better to use CSS `transform` instead).
    deleteDelay: 300 // time until the toast is completely removed from the DOM after deleting. 
});

Styles

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