Notifications are triggered via the API:

    group: 'foo',

    // (optional)
    // Title (will be wrapped in div.notification-title)
    title: 'This is the <em>title</em>',

    // Content (will be wrapped in div.notification-content)
    text: 'This is some <b>content</b>',

    // (optional)
    // Class that will be assigned to the notification
    type: 'warn',

  })

To remove notifications, include the clean: true parameter.

this.$notify({
  group: 'foo', // clean only the foo group
  clean: true
})

Plugin Options

Configure the plugin itself using an additional options object:

app.use(Notifications({ name: 'alert' }))

All options are optional:

Name	Type	Default	Description
name	String	notify	Defines the instance name. It's prefixed with the dollar sign. E.g. $notify
componentName	String	notifications	The component's name

Note: setting componentName can cause issues when using SSR.

Features

Position

Position the component on the screen using the position prop:

<notifications position="bottom right"/>

It requires a string with two keywords for vertical and horizontal postion.

Format: "<vertical> <horizontal>".

• Horizontal options: left, center, right
• Vertical options: top, bottom

Default is "top right".

Width

Width can be set using a number or string with optional % or px extensions:

<notifications :width="100"/>
<notifications width="100"/>
<notifications width="100%"/>
<notifications width="100px"/>

Type

Set the type of a notification (warn, error, success, etc) by adding a type property to the call:

this.$notify({ type: 'success', text: 'The operation completed' })

This will add the type (i.e. "success") as a CSS class name to the .vue-notification element.

See the Styling section for how to hook onto the class and style the popup.

Groups

For different classes of notifications, i.e...

• authentication errors (top center)
• app notifications (bottom-right)

...specify the group attribute:

<notifications group="auth" position="top"/>
<notifications group="app"  position="bottom right"/>

Trigger a notification for a specific group by specifying it in the API call:

this.$notify({ group: 'auth', text: 'Wrong password, please try again' })

Customisation

Styling

Vue Notifications comes with default styling, but it's easy to replace with your own.

Specify one or more class hooks via the classes prop on the global component:

<notifications classes="my-notification"/>

This will add the supplied class/classes to individual notification elements:

<div class="vue-notification-wrapper">
  <div class="vue-notification-template my-notification">
    <div class="notification-title">Info</div>
    <div class="notification-content">You have been logged in</div>
  </div>
</div>

Then include custom css rules to style the notifications:

// style of the notification itself
.my-notification {
  /*...*/

  // style for title line
  .notification-title {
    /*...*/
  }

  // style for content
  .notification-content {
    /*...*/
  }

  // additional styling hook when using`type` parameter, i.e. this.$notify({ type: 'success', message: 'Yay!' })
  &.success { /*...*/ }
  &.info { /*...*/ }
  &.error { /*...*/ }
}

Note that the default rules are:

.vue-notification {
  // styling
  margin: 0 5px 5px;
  padding: 10px;
  font-size: 12px;
  color: #ffffff;

  // default (blue)
  background: #44A4FC;
  border-left: 5px solid #187FE7;

  // types (green, amber, red)
  &.success {
    background: #68CD86;
    border-left-color: #42A85F;
  }

  &.warn {
    background: #ffb648;
    border-left-color: #f48a06;
  }

  &.error {
    background: #E54D42;
    border-left-color: #B82E24;
  }
}

Content

To completely replace notification content, use Vue's slots system:

<notifications>
  <template slot="body" slot-scope="{ item, close }">
    <div class="my-notification">
      <p class="title">
        {{ item.title }}
      </p>
      <button class="close" @click="close">
        <i class="fa fa-fw fa-close"></i>
      </button>
      <div v-html="props.item.text"/>
    </div>
  </template>
</notifications>

The props object has the following members:

Name	Type	Description
item	Object	Notification object
close	Function	A function to close the notification

Animation

Vue Notification can use the Velocity library to power the animations using JavaScript.

To use, manually install velocity-animate & pass the library to the vue-notification plugin (the reason for doing that is to reduce the size of this plugin).

In your main.js:

import { createApp } from 'vue'
import Notifications from '@kyvg/vue3-notification'
import velocity from 'velocity-animate'

const app = createApp({...})
app.use(Notifications({ velocity }))

In the template, set the animation-type prop:

<notifications animation-type="velocity"/>

The default configuration is:

{
  enter: { opacity: [1, 0] },
  leave: { opacity: [0, 1] }
}

To assign a custom animation, use the animation prop:

<notifications animation-type="velocity" :animation="animation"/>

Note that enter and leave can be an object or a function that returns an object:

computed: {
  animation () {
    return {
      /**
       * Animation function
       *
       * Runs before animating, so you can take the initial height, width, color, etc
       * @param  {HTMLElement}  element  The notification element
       */
      enter (element) {
        let height = element.clientHeight
        return {
          // animates from 0px to "height"
          height: [height, 0],

          // animates from 0 to random opacity (in range between 0.5 and 1)
          opacity: [Math.random() * 0.5 + 0.5, 0]
        }
      },
      leave: {
        height: 0,
        opacity: 0
      }
    }
  }
}
