Usage

@Input() options:

  • animationSpeed [integer] - speed of animation in ms (defaults to 100)
  • customPadding [string] - custom padding-right between stars, e.g. '10px' (defaults to 0.$sizerem e.g. 0.2rem with size=2)
  • wholeStars [boolean] - if this is true only whole star numbers are able to be selected (defaults to false)
  • customStarIcons [object of form { empty: string, half: string, full: string }] - CSS URLs to alternative image files to use instead of the default stars
How to use customStarIcons

If you want to use the default (Font Awesome 5) star icons, there's no need to use this param, but if you want to use other icons do the following:

  • Find 3 SVG files that you want to use, one for 'empty', one for 'half' and one for 'full'
  • Include the files in a part of your application that will be accessible when running, e.g. the src/assets folder
  • Alternatively the images can be hosted elsewhere on the internet
  • For each file you will need its CSS url()
  • Create an object that contains all 3 urls and adheres to the { empty: string, half: string, full: string } format
  • Pass the object into the ngx-stars instance. The example below assumes src/assets contains heart-empty.svg, heart-half.svg and heart-full.svg
// src/app/app.component.ts
heartIcons = {
    empty: '../assets/heart-empty.svg',
    half: '../assets/heart-half.svg',
    full: '../assets/heart-full.svg',
}

// src/app/app.component.html
<ngx-stars [readonly]="false" [size]="4" [initialStars]="2.5" [customStarIcons]="heartIcons"></ngx-stars>
@Output() options:
  • ratingOutput - provides the current rating as a float every time user changes it

Examples

  • <ngx-stars [readonly]="true"></ngx-stars>

  • <ngx-stars [readonly]="true" [color]="'dodgerblue'" [size]="2"></ngx-stars>
  • <ngx-stars [readonly]="true" [color]="'#FF0000'" [size]="5"></ngx-stars>
editable, 5 stars, none filled
  • <ngx-stars></ngx-stars>
