Installation

Get Angular Star Rating:

• clone & build this repository
• download as .zip
• via npm: by running $ npm install angular-star-rating --save from your console

Consuming the library

As a precondition we consider you have your .angular-cli.json setup with an assets folder so that the ./src/assets folder is included in the bundled version. But this is given by default if you use the angular-cli to setup your project.

Now you can import your library in your angular application by running:

$ npm install angular-star-rating --save

or

$ npm install angular-star-rating@2.0.0-rc.5 --save

for a specific version.

Create an assets folder under your ./src folder and copy the images from your ./node_modules/assets/images folder into ./src/assets/images.

In your app.module.ts import the StarRatingModule to your Angular AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';  
  

// IMPORT YOUR LIBRARY
import { StarRatingModule } from 'angular-star-rating';
  
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
  
    // SPECIFY YOUR LIBRARY AS AN  IMPORT
    StarRatingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Once your library is imported, you can use the components in your Angular application:

<!-- You can now use your library component in app.component.html -->
<h1>
  {{title}}
</h1>
  
<!-- USE COMPONENT HERE-->
<star-rating-comp [rating]="2.63"></star-rating-comp>

If something is not working check if

• the component renders the expected html
• if you use the svg version check if the star-rating.icons.svg is present in your ./src/assets/images and loaded
