## 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](https://github.com/Sunbird-Knowlg/sunbird-pdf-player/blob/release-5.5.0/web-component/sunbird-pdf-player.js) as below: ```javascript ``` - Update below script in index.html file ```javascript ``` - Get sample playerConfig from here: [playerConfig](https://github.com/Sunbird-Knowlg/sunbird-pdf-player/blob/release-5.5.0/src/app/data.ts) - Create a custom html element: `sunbird-pdf-player` ```javascript const pdfElement = document.createElement('sunbird-pdf-player'); ``` - Pass data using `player-config` ```javascript 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** ```javascript pdfElement.addEventListener('playerEvent', (event) => { console.log("On playerEvent", event); }); pdfElement.addEventListener('telemetryEvent', (event) => { console.log("On telemetryEvent", event); }); ``` - Append this element to existing element ```javascript const myPlayer = document.getElementById("my-player"); myPlayer.appendChild(pdfPlayerElement); ``` - Refer demo [example](https://github.com/Sunbird-Knowlg/sunbird-pdf-player/blob/release-5.5.0/web-component-demo/index.html) - To run the demo project, use the following commands: ```bash cd web-component-demo npx http-server --cors . ``` open [http://127.0.0.1:8080/](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](https://www.npmjs.com/package/http-server). - ![demo](https://github.com/Sunbird-Knowlg/sunbird-pdf-player/blob/release-5.5.0/web-component-demo/pdf-player-wc.png) # Use as Web component in the Angular app - Run command ```bash 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 ```bash "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 ```javascript ... 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 ```bash
``` 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. ```bash .... @ViewChild('pdf') pdf: ElementRef; .... ngAfterViewInit() { const playerConfig = ; 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); } .... ``` **Note:** : Click to see the mock - [playerConfig](https://github.com/Sunbird-Knowlg/sunbird-pdf-player/blob/release-5.5.0/src/app/data.ts) and 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](https://angular.io/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: ```red 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 ```red 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: ```bash 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 ```diff { ... "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: ```diff + 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](https://github.com/Sunbird-Knowlg/sunbird-pdf-player/blob/release-5.5.0/src/app/data.ts) ## Player config ```js var playerConfig = { "context": { "mode": "play", // To identify preview used by the user to play/edit/preview "authToken": "", // Auth key to make api calls "sid": "7283cf2e-d215-9944-b0c5-269489c6fa56", // User sessionid on portal or mobile "did": "3c0a3724311fe944dec5df559cc4e006", // Unique id to identify the device or browser "uid": "anonymous", // Current logged in user id "channel": "505c7c48ac6dc1edc9b08f21db5a571d", // Unique id of the channel(Channel ID) "pdata": { "id": "sunbird.portal", // Producer ID.
