Customizable Stackable Toast & Growl Notification Library – yetialerts

yetialerts is a lightweight JavaScript library to display customizable toast- and growl-style alert notifications on your web app where you need to communicate with users through status messages, alerts, and notifications.

This library provides smooth fade/slide animations, stackable alerts, pre-built themes and supports multiple notification types for different scenarios – success, warnings, error, and information.

How to use it:

1. Download and load the yetialerts’ JavaScript and CSS files in the document.

<link rel="stylesheet" href="/yeti-alerts.css" />
<script src="/yeti-alerts.js"></script>

2. Initialize YetiAlerts and display your first alert notification:

const yeti = new Yeti();

yeti.show({
  message: 'This is a default alert!'
});

3. Set different notification types using the severity option: ‘ok’, ‘nok’, ‘warn’, and ‘info’

yeti.show({
  message: 'This is a warning alert!',
  severity: 'warn'
});

4. By default, the alerts fade when the next alert appears. You can disable that by adding the fadeOnNext: false option.

yeti.show({
  message: 'This is a warning alert!',
  fadeOnNext: false
});

5. By default, alerts persist until you close them or another alert appears (unless fadeOnNext: false is set). You can set a duration for the alert to automatically disappear using the time option (in milliseconds). Setting a time value makes the alert non-closable.

yeti.show({
  message: 'This is a warning alert!',
  time: 5000
});

6. You can further customize alerts with these options:

yeti.show({
  title: '', 
  width: 50,
  shadow: true,
  border: 0,
});

7. You can modify the look of the alerts using CSS variables. Override these variables in your stylesheet’s :root or a specific CSS rule:

:root {
  --yeti-bg-ok: #ebffec;
  --yeti-ok: #31a335;
  --yeti-bg-nok: #fdf2f1;
  --yeti-nok: #f44336;
  --yeti-bg-warn: #fff8ec;
  --yeti-warn: #ed7a00;
  --yeti-bg-info: #e6f4ff;
  --yeti-info: #0083ee;
  --yeti-close: #777;
  --yeti-shadow: #00000025;
  --yeti-radius: 5px;
  --yeti-gap: 10px;
  --yeti-font: 1em;
}
