Installation

Install it with npm

npm install --save ngx-bar-rating

SystemJS

If you are using SystemJS, you should also adjust your configuration to point to the UMD bundle.

In your systemjs config file, map needs to tell the System loader where to look for ngx-bar-rating:

map: {
  'ngx-bar-rating': 'node_modules/ngx-bar-rating/bundles/ngx-bar-rating.umd.js',
}

Here is a working plunkr

Basic usage:

Import BarRatingModule in the root module

import { BarRatingModule } from "ngx-bar-rating";

@NgModule({
  imports: [
    // ...
    BarRatingModule
  ]
})

In your template

<bar-rating [(rate)]="rate" [max]="5"></bar-rating>

Rating options (inputs):

• [rate]: Current rating. Can be a decimal value like 3.14, default undefined.

• [max]: Maximal rating that can be given using this widget, default 5

• [readOnly]: A flag indicating if rating can be updated, default false

• [theme]: Theme class. default default, see available themes.

• [showText]: Display rating title if set, otherwise display rating value, default false.

• [titles]: Titles array. array length should be equal to the max value, each index represents the rating title, default [].

• [required]: A flag indicating if rating is required for form validation. default false.

• [disabled]: A flag indicating if rating is disabled. works only with forms, default false.

• (rateChange): An event fired when a user selects a new rating.

  Event's payload equals to the newly selected rating.

• (hover): An event fired when a user is hovering over a given rating.

  Event's payload equals to the rating being hovered over.

• (leave): An event fired when a user stops hovering over a given rating.

  Event's payload equals to the rating of the last item being hovered over.

Movie rating example

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

It can be used with angular forms and reactive forms, for example:

<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>

Predefined themes

Add the rating theme either in index.html

<link rel="stylesheet" href="../node_modules/ngx-bar-rating/themes/br-default-theme.css"/>

Or in the global style style.scss (recommended)

• Pure css stars (default) [theme]="'default'"

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

• Bootstrap stars [theme]="'bootstrap'"

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

• Fontawesome stars [theme]="'fontawesome'"

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

• Fontawesome-o stars [theme]="'fontawesome-o'"

@import '~ngx-bar-rating/themes/br-fontawesome-o-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

If you have a nice rating style you would like to share, prupose your theme and I will include it in the package.
