Minimal Toast Alert JavaScript Library – Alert.js

A minimal yet customizable JavaScript library to generate success, error, warning, and info toast messages with one JS call.

The toast-style alerts are accompanied by a countdown progress bar indicating the remaining time before the alert disappears. OPTIONAL.

How to use it:

1. Install and import the alert component.

# NPM
$ npm i @bjnstnkvc/alert

import Alert from '@bjnstnkvc/alert'
// default styles
import '@bjnstnkvc/alert/src/alert.css'

<!-- OR -->
<link rel="stylesheet" href="src/alert.css" />
<script src="lib/Alert.js"></script>

2. Create success, error, warning, and info toast messages.

new Alert({
    type: 'success',
    message: 'Toast Message Here', 
})
new Alert({
    type: 'error',
    message: 'Toast Message Here', 
})
new Alert({
    type: 'warning',
    message: 'Toast Message Here', 
})
new Alert({
    type: 'info',
    message: 'Toast Message Here', 
})

3. Determine whether to display a countdown bar under the alert. Default: false.

new Alert({
    type: 'success',
    message: 'Toast Message Here', 
    withProgress: true,
})

4. Specify the parent container in which the alerts are placed. Default: body.

new Alert({
    type: 'success',
    message: 'Toast Message Here', 
    container: '.anotherElement',
})

5. Determine whether to auto-dismiss the alerts after a timeout. Default: true.

new Alert({
    type: 'success',
    message: 'Toast Message Here', 
    expires: true,
    duration: 10,
})

6. Determine whether to display a close button inside the alerts. Default: true.

new Alert({
    type: 'success',
    message: 'Toast Message Here', 
    close: false,
})

7. Replace the default icons.

new Alert({
    type: 'info',
    message: 'Toast Message Here', 
    info: '',
}

8. Override the default CSS varaibles to create your own styles/types.

:root {
  --alert-success : rgba(118, 189, 87, 1);
  --alert-error   : rgba(214, 45, 48, 1);
  --alert-warning : rgba(238, 146, 19, 1);
  --alert-info    : rgba(63, 175, 239, 1);
}
