The PDF player for the Sunbird!

The PDF player library is powered by Angular. This player is primarily designed to be used on Sunbird consumption platforms (mobile app, web portal, offline desktop app) to drive reusability and maintainability, hence reducing the redundant development effort significantly, and it can be integrated with any platform irrespective of the platforms and the frontend frameworks. It is exported not only as an angular library but also as a web component.

Getting started with integration steps

The pdf player can be integrated as a web component and also as an angular library in angular application projects and it can also be integrated into any mobile framework as a web component.

Use as web components

Any web based application can use this library as a web component. It accepts couple of inputs and triggers player and telemetry 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 demo project, use the following commands:
```
cd web-component-demo
 npx http-server --cors .
```
open http://127.0.0.1:8080/ Note: Due to cors errors when you open the index.html from demo folder as file, it is recomanded to run a static server in it like http-server.

Use as Web component in the Angular app

Run command

  npm i @project-sunbird/sunbird-pdf-player-web-component
  npm i reflect-metadata

Add these entries in angular json file inside assets, scripts and styles like below

          "assets": [
            "src/favicon.ico",
            "src/assets",
            {
              "glob": "**/*.*",
              "input": "./node_modules/@project-sunbird/sunbird-pdf-player-web-component/assets",
              "output": "/assets/"
            }
          ],
          "styles": [
            "src/styles.scss",
            "node_modules/@project-sunbird/sunbird-pdf-player-web-component/styles.css"
          ],
          "scripts": [
            "node_modules/reflect-metadata/Reflect.js",
            "node_modules/@project-sunbird/sunbird-pdf-player-web-component/sunbird-pdf-player.js"
          ]

Import CUSTOM_ELEMENTS_SCHEMA in app module and add it to the NgModule as part of schemas like below

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

@NgModule({
 ...
 schemas: [CUSTOM_ELEMENTS_SCHEMA],
 ...
})

Integrating sunbird-pdf-player web component in angular component

Create a viewChild in html template of the angular component like
```
    <div #pdf></div>
```
Refer the viewChild in ts file of the component and create the pdf player using document.createElement, then attach the player config and listen to the player and telemetry events like below and since we are rendering using viewChild these steps should be under ngAfterViewInit hook of the angular component.

....

@ViewChild('pdf') pdf: ElementRef;

  ....
 ngAfterViewInit() {
    const playerConfig = <Config need be added>;
      const pdfElement = document.createElement('sunbird-pdf-player');
      pdfElement.setAttribute('player-config', JSON.stringify(playerConfig));

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

      pdfElement.addEventListener('telemetryEvent', (event) => {
        console.log("On telemetryEvent", event);
      });
      this.pdf.nativeElement.append(pdfElement);
  }
  ....

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
