Pdf player library for Sunbird platform!

Contains PDF player library components powered by angular. These components are designed to be used in sunbird consumption platforms (mobile app, web portal, offline desktop app) to drive reusability, maintainability hence reducing the redundant development effort significantly.

Getting Started with different integrations steps

The pdf player can be integrated as web component in plain javascript projects and as web component in angular apps and also as angular library in angular and mobile applications.

Use as web components

Any web application can use this library as a web component. It accepts couple of inputs and triggers some events back to the application.

Follow below-mentioned steps to use it in plain javascript project:

• Insert library as below:

   <script type="text/javascript" src="sunbird-pdf-player.js"></script>

• Update below script in index.html file

     <script src="https://cdnjs.cloudflare.com/ajax/libs/reflect-metadata/0.1.13/Reflect.min.js"
     integrity="sha512-jvbPH2TH5BSZumEfOJZn9IV+5bSwwN+qG4dvthYe3KCGC3/9HmxZ4phADbt9Pfcp+XSyyfc2vGZ/RMsSUZ9tbQ=="
     crossorigin="anonymous" referrerpolicy="no-referrer"></script>

• Get sample playerConfig from here: playerConfig

• Create a custom html element: sunbird-pdf-player

   const  pdfElement = document.createElement('sunbird-pdf-player');

• Pass data using player-config

   pdfElement.setAttribute('player-config', JSON.stringify(playerConfig));

  Note: Attribute name should be in kebab-case regardless of the actual Attribute name used in the Angular app. The value of the attribute should be in string type, as web-component does not accept any objects or arrays.

• Listen for the output events: playerEvent and telemetryEvent

   pdfElement.addEventListener('playerEvent', (event) => {
   	console.log("On playerEvent", event);
   });
   pdfElement.addEventListener('telemetryEvent', (event) => {
   	console.log("On telemetryEvent", event);
   });

• Append this element to existing element

   const  myPlayer = document.getElementById("my-player");
   myPlayer.appendChild(pdfPlayerElement);

• Refer demo example

• To run the project, use the following command:

   npm run build-web-component
   http-server --cors web-component .

  open http://127.0.0.1:8081/web-component/ Note: There are some request for which we need to run this on server, so we need to run this on server for demo purpose we are using http-server.

• 

Use as Web component in the Angular app

• Copy the assets files from web component folder assets to assets folder

• Create sunbird folder inside assets folder, and copy sunbird-pdf-player.js and styles.css. and Add/import these entries in angular json file inside scripts and styles respectively.

• Add the reflect-metadata script to index.html file

     <script src="https://cdnjs.cloudflare.com/ajax/libs/reflect-metadata/0.1.13/Reflect.min.js"
     integrity="sha512-jvbPH2TH5BSZumEfOJZn9IV+5bSwwN+qG4dvthYe3KCGC3/9HmxZ4phADbt9Pfcp+XSyyfc2vGZ/RMsSUZ9tbQ=="
     crossorigin="anonymous" referrerpolicy="no-referrer"></script>

• Import CUSTOM_ELEMENTS_SCHEMA in app module

  import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';

• Import sunbird-pdf-player in component

  <sunbird-pdf-player  [playerConfig]="playerConfig" (playerEvent)="playerEvents($event)"
  (telemetryEvent)="playerTelemetryEvents($event)"></sunbird-pdf-player>

• Provide input to render PDF player

Use the mock config in your component to send input to PDF player Click to see the mock - playerConfig Note: : Send input config as string

Use as Angular library in angular app

For help getting started with a new Angular app, check out the Angular CLI. If you have an Angular ≥ 9 CLI project, you could simply use our schematics to add sunbird-pdf-player library to it.

Step 1: Installation

Just run the following:

ng add @project-sunbird/sunbird-pdf-player-v9

It will install sunbird-pdf-player for the default application specified in your angular.json. If you have multiple projects and you want to target a specific application, you could specify the --project option

ng add @project-sunbird/sunbird-pdf-player-v9 --project myProject

Manual installation

If you prefer not to use schematics or want to add sunbird-pdf-player-v9 to an older project, you'll need to do the following:

Click here to show detailed instructions!

1. Install the packages:

npm install @project-sunbird/sunbird-pdf-player-v9 --save
npm install @project-sunbird/sb-styles --save
npm install @project-sunbird/client-services --save

2. Include the sb-styles and assets in angular.json configuration:

Add following under architect.build.assets and styles

{
  ...
  "build": {
  "builder": "@angular-devkit/build-angular:browser",
  "options": {
    ...
    "assets": [
    ...
+   {
+    "glob": "**/*.*",
+    "input": "./node_modules/@project-sunbird/sunbird-pdf-player-v9/lib/assets/",
+    "output": "/assets/"
+   }	
    ...    
    ],
    "styles": [
    ...
+   "./node_modules/@project-sunbird/sb-styles/assets/_styles.scss"    
    ...
    ],
    ...
  }

3. Import the modules and components:

Import the NgModule where you want to use:

+  import { SunbirdPdfPlayerModule } from '@project-sunbird/sunbird-pdf-player-v9';
@NgModule({
  ...
+    imports: [SunbirdPdfPlayerModule],
  ...
})
export class YourAppModule { }

Step 2: Send input to render PDF player

Use the mock config in your component to send input to PDF player Click to see the mock - playerConfig
