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>

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
