import StarRating from 'vue-star-rating'

Then you can register the component globally:

Vue.component('star-rating', StarRating);

Or in your Vue component:

components: {
  StarRating
}

You can then use the following markup in your project:

<star-rating></star-rating>

Via CDN

You may also include vue-star-rating directly in to your webpage via Unpkg. Simply add the following script tag:

<script src="https://unpkg.com/vue-star-rating/dist/star-rating.min.js"></script>

You will need to register the component by doing:

Vue.component('star-rating', VueStarRating.default);

You may also register the component locally via the components option.

Getting Started

To get started with vue-star-rating you will want to sync the rating values between the component and parent, you can then take a look at the props and custom events section of the docs to customise your star-rating component.

Syncing Rating Values with V-Model for Vue 2.2 +

vue-star-rating supports v-model when using Vue 2.2 and above, which is the simplest way to keep your ratings in sync:

<star-rating v-model="rating"></star-rating>

See this example on JSFiddle

Syncing Rating Values when using Vue 2.1.x and below

If you are using Vue 2.1.x or below the following is the equivelent to the v-model example above:

<star-rating @rating-selected="rating = $event" :rating="rating"></star-rating>

See this example on JSFiddle

Docs

Props

The following props can be passed to the component:

General Props

These props provide general functionailty to the star rating component

Prop	Description	Default
increment	The rating increment, for example pass 0.5 for half stars or 0.01 for fluid stars. Expects a number between 0.01 - 1.	1
rating	The initial rating, this will automatically round to the closest increment, so for the most accurate rating pass 0.01 as increment or set the round-start-rating prop to false	0
max-rating	The maximum rating, this lets vue-star-rating know how many stars to display	5
star-points	The points defining a custom star shape. If no points are passed the default star shape is used.	[]
read-only	When set to true, the rating cannot be edited. Use in conjuction with increment to define rounding precision.	false
show-rating	Whether or not to show the rating next to the stars	true
fixed-points	Specify a fixed number of digits after the decimal point.	null
rtl	Pass true to display star rating using rtl (right-to-left)	false
round-start-rating	Pass false if you don't want the start rating value to round to the closest increment. The user will still only be able to select based on the given increment.	true

Style Props

These props are used to style the star rating component

Prop	Description	Default
star-size	The size of each star, this gets passed to the SVG width attribute, so larger numbers are larger stars	50
inactive-color	The color of the non-highlighted portion of a star.	#d8d8d8
active-color	The color of the highlighted portion of a star.	#ffd055
border-color	Sets the colour of the border for each star	#999
border-width	Sets the width of the border for each star	0
padding	Pads the right of each star so distance between stars can be altered	0
rounded-corners	Whether or not to round the star's corners	false
inline	Sets the star rating to display inline	false
glow	Adds a subtle glow around each active star, this should be a number to spread the glow	0
glow-color	Sets the color for the glow (note, this effect can be very subtle)	#000
text-class	A css class name to style the rating text for a specific star rating component	''

Important: Vue requires you to pass numbers and boolean values using v-bind, any props that require a number or bool should use v-bind: or the colon (:) shorthand.

Props Example

<star-rating v-bind:increment="0.5"
             v-bind:max-rating="3"
             inactive-color="#000"
             active-color="#f00"
             v-bind:star-size="90">
</star-rating>

Custom Events

vue-star-rating fires the following custom events, simply use v-on:event or the @ shortand to capture the event.

Event	Description	Return Value
rating-selected	Returns the rating the user selects via the click event	rating
current-rating	Returns the rating that the users mouse is currently over	rating

Custom Events Example

<star-rating @rating-selected ="setRating"></star-rating>

Then in your view model:

new Vue({
  el: '#app',
  methods: {
    setRating: function(rating){
      this.rating= rating;
    }
  },
  data: {
    rating: 0
  }
});

Note: When writing methods to capture custom events, the rating param is automatically passed to the method. If you need to declare methods with multiple paramaters you will need to use $event to pass the rating to the method:

<star-rating @current-rating="setCurrentRating($event, anotherParam)"></star-rating>

IE9 Support

vue-star-rating supports IE 9+; make sure you place the following in the head of your webpage to ensure that IE is in standards mode:
