Basic Alert Messages in JavaScript

// Create an instance of Notyf
var notyf = new Notyf();

// Display an error notification
notyf.error('You must fill out the form before moving forward');

// Display a success notification
notyf.success('Your changes have been successfully saved!');

Examples

Global Configuration

The following example configures Notyf with the following settings:

  • 1s duration
  • Render notifications in the top-right corner
  • New custom notification called ‘warning’ with a ligature material icon
  • Error notification with custom duration, color and dismiss button
const notyf = new Notyf({
  duration: 1000,
  position: {
    x: 'right',
    y: 'top',
  },
  types: [
    {
      type: 'warning',
      background: 'orange',
      icon: {
        className: 'material-icons',
        tagName: 'i',
        text: 'warning'
      }
    },
    {
      type: 'error',
      background: 'indianred',
      duration: 2000,
      dismissible: true
    }
  ]
});

Custom toast type

const notyf = new Notyf({
  types: [
    {
      type: 'info',
      background: 'blue',
      icon: false
    }
  ]
});

notyf.open({
  type: 'info',
  message: 'Send us <b>an email</b> to get support'
});
