    // Name of the notification holder
    group: 'foo',

    // (optional)
    // Title (will be wrapped in div.notification-title)

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

    // (optional)

    data: {}
  })
JavaScript

To remove notifications, include the clean: true parameter.

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

Plugin Options

Configure the plugin itself using an additional options object:

app.use(Notifications({ name: "alert" }));
Js

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" />
Vue

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" />
Vue

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" });
Js

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" />
Vue

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

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

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" />
Vue

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>
HTML

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 {
    /*...*/
  }
}
Sass (Scss)

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;
  }
}
Sass (Scss)

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>
Vue

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 ))
JavaScript

In the template, set the animation-type prop:

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

The default configuration is:

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

To assign a custom animation, use the animation prop:

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

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
      }
    }
  }
}
JavaScript
