Installation

Install it with npm

npm i ngx-bar-rating

Basic usage:

Import BarRating or BarRatingModule in your component imports.

@Component({
  standalone: true,
  selector: 'bars',
  template: `
    <bar-rating [(rate)]="rate"/>
  `,
  styleUrl: './example.component.scss',
  imports: [BarRating]
})
export class BarsComponent {
  rate: number = 4;
}

Import the theme in your global styles (unless you want to use custom template)

@import 'ngx-bar-rating/themes/br-default-theme';

Rating inputs and outputs:

Custom rating template

BarRatingModule provides a couple of directives to set custom rating template of your choice.

• *ratingActive: Set template, when a bar/star is active or hovered.
• *ratingInactive: Set template, when a bar/star is inactive.
• *ratingFraction: Set template, when a bar/star is a fraction.

Here are some example:

Bootstrap rating example

<bar-rating [(rate)]="rate" max="5">
  <i *ratingActive class="bi bi-star-fill" style="margin: 2px; color: #edb867"></i>
  <i *ratingInactive class="bi bi-star-fill" style="margin: 2px; color: #d2d2d2"></i>
</bar-rating>

FontAwesome rating example

<bar-rating [(rate)]="rate" max="10">
  <fa-icon *ratingInactive [icon]="['far', 'star']" [fixedWidth]="true" size="lg" style="color: #d2d2d2"/>
  <fa-icon *ratingActive [icon]="['fas', 'star']" [fixedWidth]="true" size="lg" style="color: #50e3c2"/>
  <fa-icon *ratingFraction [icon]="['fas', 'star-half-alt']" [fixedWidth]="true" size="lg" style="color: #50e3c2"/>
</bar-rating>

Movie rating example

<bar-rating [(rate)]="rate" max="4" theme="movie" showText
            [titles]="['Bad', 'Mediocre' , 'Good', 'Awesome']"/>

It can be used with Angular forms:

<form #form="ngForm">
  <bar-rating name="rating" [(ngModel)]="formRating" [max]="4" required disabled></bar-rating>
</form>
<p>form is valid: {{ form.valid ? 'true' : 'false' }}</p>
<pre>{{ formRating }}</pre>

And reactive forms:

<form [formGroup]="ratingForm">
  <bar-rating formControlName="rate" [max]="4" required disabled></bar-rating>
</form>
<p>form is valid: {{ form.valid ? 'true' : 'false' }}</p>
<pre>{{ formRating }}</pre>

CSS variables

• --br-font-size Sets the size of the step for the following themes: [default, square, stars].
• --br-width Sets the width of the step for the following themes: [stars, square, movie, vertical, horizontal].
• --br-height Sets the height of the step for the following themes: [stars, square, movie, vertical, horizontal].
• --br-gap Sets the gap between the stars.
• --br-active-color Sets active color.
• --br-inactive-color Sets inactive color.

Predefined themes

If you want to use a custom rating template, you don't need to import any CSS theme.

If you want to use one of the predefined themes, you will need to import it in the global style style.scss

• Pure CSS stars (default) theme="default"

@import 'ngx-bar-rating/themes/br-default-theme';

• Horizontal bars theme="horizontal"

@import 'ngx-bar-rating/themes/br-horizontal-theme';

• Vertical bars theme="vertical"

@import 'ngx-bar-rating/themes/br-vertical-theme';

• Custom stars theme="stars"

@import 'ngx-bar-rating/themes/br-stars-theme';

• Movie rating theme="movie"

@import 'ngx-bar-rating/themes/br-movie-theme';

• Square rating theme="square"

@import 'ngx-bar-rating/themes/br-square-theme';

Rating style can be easily customized, check the classes used in any theme and add your own css.

You can also do the same for forms classes such as untouched, touched, dirty, invalid, valid ...etc
