API

  this.$notify({
    // (optional)
    // Name of the notification holder
    group: 'foo',

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

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

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

    // Overrides default/provided duration
    duration: 10000,

    // (optional)
    // Overrides default/provided animation speed
    speed: 1000
  })

Title and Text can be HTML strings.

Also you can use simplified version:

this.$notify('text')

Groups

If you are planning to use notification component for 2 or more completely different types of notifications (for example, authentication error messages in top center and generic app notifications in bottom-right corner) - you can specify group property which is essentially a name of notification holder.

Example:

<notifications group="auth"/>
<notifications group="app"/>

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

Position

Position property requires a string with 2 keywords for vertical and horizontal postion.

Format: "<vertical> <horizontal>".

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

Default is "top right".

Style

You can write your own css styles for notifications:

Structure:

// SCSS:

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

  .notification-title {
    // Style for title line
  }

  .notification-content {
    // Style for content
  }

  &.my-type {
    /*
    Style for specific type of notification, will be applied when you
    call notification with "type" parameter:
    this.$notify({ type: 'my-type', message: 'Foo' })
    */
  }
}

To apply this style you will have to specify "classes" property:

  <notifications classes="my-style"/>

Default:

.vue-notification {
  padding: 10px;
  margin: 0 5px 5px;

  font-size: 12px;

  color: #ffffff;
  background: #44A4FC;
  border-left: 5px solid #187FE7;

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

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

  &.success {
    background: #68CD86;
    border-left-color: #42A85F;
  }
}

Custom template (slot)

Optional scope slot named "body" is supported.

Scope props:

Name	Type	Description
item	Object	notification object
close	Function	when called closes the notification

Example:

<notifications group="custom-template"  
               position="bottom right">
   <template slot="body" scope="props">
    <div>
        <a class="title">
          {{props.item.title}}
        </a>
        <a class="close" @click="props.close">
          <i class="fa fa-fw fa-close"></i>
        </a>
        <div v-html="props.item.text">
        </div>
    </div>
  </template>
</notifications>

Width

Width can be set using a string with a percent or pixel extension (if simple number is not enough).

Examples: '100%', '50px', '50', 50

Velocity Animation

Plugin can use use Velocity library to make js-powered animations. To start using it you will have to manually install velocity-animate & supply the librarty to vue-notification plugin (reason for doing that is to reduce the size of this plugin).

In your main.js:

import Vue           from 'vue'
import Notifications from 'vue-notification'
import velocity      from 'velocity-animate'

Vue.use(Notifications, { velocity })

In the template you will have to set animation-type="velocity".

<notifications animation-type="velocity"/>

The animation configuration consists of 2 objects/functions: enter and leave.

Example:

/*
 * Both 'enter' and 'leave' can be either an object or a function
 */
animation = {
  enter (element) {
     /*
      *  "element" - is a notification element
      *    (before animation, meaning that you can take it's initial height, width, color, etc)
      */
     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
  }
}

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

TypeScript support

You will have to extend Vue type declaration:

import Notification from 'vue-notification';

declare module 'vue/types/vue' {
  export interface Vue {
    $notify: Notification;
  }
}
