Build your web apps using Smart UI
Smart.Rating - configuration and usage
Getting Started with Rating Web Component
Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.Setup the Rating
Smart UI for Web Components is distributed as smart-webcomponents NPM package
- Download and install the package.
npm install smart-webcomponents
- Once installed, import the Rating module in your application.
<script type="module" src="node_modules/smart-webcomponents/source/modules/smart.rating.js"></script>
-
Adding CSS reference
The smart.default.css CSS file should be referenced using following code.
<link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />
- Add the Rating tag to your Web Page
<smart-rating id="rating"></smart-rating>
- Create the Rating Component
<script type="module"> Smart('#rating', class { get properties() { return { value: 5 } } }); </script>
Another option is to create the Rating is by using the traditional Javascript way:
const rating = document.createElement('smart-rating'); rating.disabled = true; document.body.appendChild(rating);
Smart framework provides a way to dynamically create a web component on demand from a DIV tag which is used as a host. The following imports the web component's module and creates it on demand, when the document is ready. The #rating is the ID of a DIV tag.
import "../../source/modules/smart.rating.js"; document.readyState === 'complete' ? init() : window.onload = init; function init() { const rating = new Smart.Rating('#rating', { value: 5 }); }
- Open the page in your web server.
Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event
Create a new element:
const rating = document.createElement('smart-rating');
Append it to the DOM:
document.body.appendChild(rating);
Remove it from the DOM:
rating.parentNode.removeChild(rating);
Set a property:
rating.propertyName = propertyValue;
Get a property value:
const propertyValue = rating.propertyName;
Invoke a method:
rating.methodName(argument1, argument2);
Add Event Listener:
const eventHandler = (event) => { // your code here. }; rating.addEventListener(eventName, eventHandler);
Remove Event Listener:
rating.removeEventListener(eventName, eventHandler, true);
Using with Typescript
Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.
Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Setup Angular Environment
Angular provides the easiest way to set angular CLI projects using Angular CLI tool.
Install the CLI application globally to your machine.
npm install -g @angular/cli
Create a new Application
ng new smart-angular-rating
Navigate to the created project folder
cd smart-angular-rating
Setup the Rating
Smart UI for Angular is distributed as smart-webcomponents-angular NPM package
- Download and install the package.
npm install smart-webcomponents-angular
- Once installed, import the RatingModule in your application root or feature module.
app.module.ts
import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, ], bootstrap: [ AppComponent ] }) export class AppModule { }
- Adding CSS reference
The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code.@import 'smart-webcomponents-angular/source/styles/smart.default.css';
Another way to achieve the same is to edit the angular.json file and in the styles add the style."styles": [ "node_modules/smart-webcomponents-angular/source/styles/smart.default.css" ]
-
Example
app.component.html
<smart-rating></smart-rating>
app.component.ts
import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent implements AfterViewInit, OnInit { ngOnInit(): void { // onInit code. } ngAfterViewInit(): void { // afterViewInit code. this.init(); } init(): void { // init code. } }
app.module.ts
import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, ], bootstrap: [ AppComponent ] }) export class AppModule { }
Running the Angular application
After completing the steps required to render a Rating, run the following command to display the output in your web browser
ng serveand open localhost:4200 in your favorite web browser.

Getting Started with React Rating Component
Setup React Environment
The easiest way to start with React is to use create-react-app. To scaffold your project structure, follow the installation instructions.
npx create-react-app my-app cd my-app npm start
Preparation
Open src/App.js andsrc/App.css
- Remove everything inside the App div tag in src/App.js:
<div className="App"> </div>
- Remove the logo.svg import
- Remove the contents of src/App.css
- Remove src/logo.svg
Setup the Rating
Smart UI for React is distributed as smart-webcomponents-react NPM package
- Download and install the package.
npm install smart-webcomponents-react
Once installed, import the React Rating Component and CSS files in your application and render it
app.js
import 'smart-webcomponents-react/source/styles/smart.default.css'; import React from "react"; import ReactDOM from 'react-dom/client'; import { Rating } from 'smart-webcomponents-react/rating'; class App extends React.Component { init() { } componentDidMount() { } render() { return ( <div> <Rating ></Rating> </div> ); } } export default App;
Running the React application
Start the app withnpm startand open localhost:3000 in your favorite web browser to see the output.

Getting Started with Vue Rating Component
Setup Vue Environment
We will use vue-cli to get started. Let's install vue-cli
npm install -g @vue/cli
Then we can start creating our Vue.js projects with:
vue create my-project
Setup the Rating
Open the "my-project" folder and run:
npm install smart-webcomponents
Setup with Vue 3.x
-
Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.
Open src/main.js in your favorite text editor and change its contents to the following:
main.js
import { createApp } from 'vue' import App from './App.vue' const app = createApp(App) app.config.isCustomElement = tag => tag.startsWith('smart-'); app.mount('#app')
-
Open src/App.vue in your favorite text editor and change its contents to the following:
App.vue
<template> <div class="vue-root"> <smart-rating></smart-rating> </div> </template> <script> import { onMounted } from "vue"; import "smart-webcomponents/source/styles/smart.default.css"; import "smart-webcomponents/source/modules/smart.rating.js"; export default { name: "app", setup() { onMounted(() => {}); } }; </script> <style> body { } </style>
We can now use the smart-rating with Vue 3. Data binding and event handlers will just work right out of the box.
Setup with Vue 2.x
-
Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.
Open src/main.js in your favorite text editor and change its contents to the following:
main.js
import Vue from 'vue' import App from './App.vue' Vue.config.productionTip = false Vue.config.ignoredElements = [ 'smart-rating' ] new Vue({ render: h => h(App), }).$mount('#app')
-
Open src/App.vue in your favorite text editor and change its contents to the following:
App.vue
We have bound the properties of the smart-rating to values in our Vue component.
Running the Vue application
Start the app withnpm run serveand open localhost:8080 in your favorite web browser to see the output below:
