Installation

🏷️ System requirements

The following are prerequisites to use question set editor

Softwares / Frameworks	Version
Angular	15.2.3

{% hint style="info" %} The Question Set Editor is tested against the above version of angular. Updating to latest versions needs further testing.

For more information on installing angular, see angular.io/cli. If you are unsure what version of Angular runs on your system, run “ng version” in a command prompt (terminal) window.

Angular requires an active LTS or maintenance LTS version of Node.js.

Refer here for more details on Angular CLI dependencies {% endhint %}

💠 Question Set Editor library for Sunbird platform

Question Set Editor library components is powered by angular. This editor is primarily designed to be used in the sunbirdEd portal and web portal to drive reusability, 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 aims to make it easy to share, discover, and reuse web components. It creates a framework agnostic way of composing and re-purposing code.

📑 Getting started with integration steps

The Question Set Editor can be integrated as a web component and also as an angular library in angular application projects.

Use as web components 🌏

Question Set Editor Library can also be used as a web component which means if your project does not use a JavaScript framework but prefers platform-based HTML, CSS, and JavaScript, you may wish to use Question Set Editor Library in this way. Simply follow the below-mentioned steps to use it in plain JavaScript project:

Insert library as below:

<script  type="text/javascript"  src="sunbird-questionset-editor.js"></script>

Copy all the files from here, the library requires these files internally to work well.
Define an html element where you want to display the editor and set an id to it. For example
```
<div id="inQuiryEditor">
</div>
```
Note - You can give any id of your choice but the same id should be used to append the questionsetEditorElement.

Create a custom HTML element: lib-questionset-editor

const questionsetEditorElement = document.createElement('lib-questionset-editor');

Get sample questionsetEditorConfig from here: questionsetEditorConfig and pass data using editor-config
```
questionsetEditorElement.setAttribute('editor-config', JSON.stringify(questionsetEditorConfig));
```
Note: Attribute should be in string type

Listen for the output events: editorEmitter as:

questionsetEditorElement.addEventListener('editorEmitter', (event) => {
  console.log("On editorEvent", event);
});

Append this element to the existing element

const inQuiryEditor = document.getElementById("inQuiryEditor");
inQuiryEditor.appendChild(questionsetEditorElement);

▶️ Refer demo example
Note: Question Set Editor requires a back-end service for making the API calls. For running the Question Set Editor you need a server where inQuiry services are up and running.
For testing purpose we are using a node.js server where the API's proxy and editor are running on localhost. For running the editor and services from localhost please refer the server.js file and run it using node server.js

Use as web component in the Angular app

Run command

npm i @project-sunbird/sunbird-questionset-editor-web-component

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

"assets": [
              "src/favicon.ico",
              "src/assets",
+             {
+              "glob": "**/*",
+              "input": "node_modules/@project-sunbird/sunbird-questionset-editor-web-component/assets/",
+               "output": "/assets/"
+             }
            ],
            "styles": [
              "src/styles.scss",
+              "./node_modules/@project-sunbird/sunbird-questionset-editor-web-component/styles.css"
            ],
            "scripts": [
+              "node_modules/@project-sunbird/sunbird-questionset-editor-web-component/sunbird-questionset-editor.js"
            ]

Integrating lib-questionset-editor web component in the angular component

Create a viewChild in HTML template of the angular component like

<div #questionsetEditor></div>

Refer to the viewChild in the ts file of the component and create the Questionset Editor using the document.createElement, then attach the editor config and listen to the editor events like below and since we are rendering using viewChildthese steps should be under the ngAfterViewInit hook of the angular component.

  import { AfterViewInit, Component, ElementRef, ViewChild } from '@angular/core';
+ import { questionSetEditorConfig } from './data';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent implements AfterViewInit {
+  @ViewChild('questionsetEditor') inQuiryEditor! : ElementRef;
  
  ngAfterViewInit() {
+   const editorConfig = questionSetEditorConfig;
+   const questionsetEditorElement = document.createElement('lib-questionset-editor');
+   questionsetEditorElement.setAttribute('editor-config', JSON.stringify(editorConfig));

+   questionsetEditorElement.addEventListener('editorEmitter', (event) => {
+     console.log("On editorEvent", event);
+   });

+   this.inQuiryEditor.nativeElement.append(questionsetEditorElement);
  }
}

Note: Click to see the mock - questionsetEditorConfig and send the input config as a string

For running different question set in the editor, set the do_id of Question Set in data.ts file as:

export const questionSetEditorConfig = {
  context: {
    ...
    ...
    ...
    },
+    identifier: 'do_id', // identifier of created questionset
    ...
    ...
  };

You're done! Question Set Editor web component integration in angular application is completed.

Note: Question Set Editor requires a back-end service to make the API calls. For running it locally we need a proxy server. You can use the below steps for doing the proxy and run the services on localhost:3000
Create a proxy.conf.json in the root folder. Refer: proxy.conf.json

Update the packge.json

{
    ...
    ...
    "scripts": {
      "ng": "ng",
+      "start": "ng serve --proxy-config proxy.conf.json",
      ...
      ...
    },
    ...
    "dependencies": {
    ...
    ...
    },
    "devDependencies": {
    ...
    ...
    }
  }

Create a latexService.js in the root folder. Refer: latexService.js

Create server.js in the root folder. Refer: server.js

Update the host variable to which env your pointing. example if you are pointing sunbird dev instance update variable like below
const BASE_URL = 'https://dev.inquiry.sunbird.org/' //add the base url of your portal
const API_AUTH_TOKEN = 'XXXX' // Add the API_KEY of your inQuiry API's.

For running the server.js file few packges are to be installed. Please install the below packages.
```
npm i express-http-proxy
npm i async
npm i mathjax-full
npm i svg2img
```
Now we are ready to run the application.
- Open one terminal in your application's root folder and run the server as below and let it keep on running.
```
node server.js
```
- Open another terminal on root folder and start your application
```
npm run start
```

Use as Angular library in Angular app

For getting started with a new Angular app, check out the Angular CLI.

For existing apps, follow the below-mentioned steps:

🏷️ Step 1: Install the packages

The following commands will add sunbird-questionset-editor library to your package.json file along with its dependencies.

npm i @project-sunbird/sunbird-questionset-editor --save

Don't forget to install the below peer dependencies of the library in your application. that need to be installed in order to use the library in your angular project.

npm i @project-sunbird/common-form-elements-full --save
npm i ng2-semantic-ui-v9 --save
npm i ngx-infinite-scroll --save
npm i lodash-es --save
npm i jquery.fancytree --save
npm i uuid --save
npm i @project-sunbird/client-services --save
npm i export-to-csv --save
npm i moment --save
npm i @project-sunbird/ckeditor-build-classic --save
npm i @project-sunbird/sunbird-quml-player-web-component --save
npm i ngx-bootstrap@^10.0.0 --save
npm i [email protected] --save
npm i jquery --save
npm i express-http-proxy --save
npm i mathjax-full --save
npm i svg2img --save
npm i font-awesome --save
npm i @project-sunbird/sb-styles

Note: As QuestionSet library is build with angular version 15, we are using "bootstrap": "^4.6.2" and ngx-bootstrap@^10.0.0 which are the compatible versions. For more reference Check compatibility document for ng-bootstrap here

🏷️ Step 2: create and copy required assests

After installing the above dependencies, now we have to copy the required assets from the given folder to the assets folder of your angular application. It contains styles and plugins.

Copy the assets from: assets

Create a latexService.js in the root folder. Refer: latexService.js
Create a proxy.conf.json in the root folder. Refer: proxy.conf.json
Create server.js in the root folder. Refer: server.js

🏷️ Step 3: Include the styles, scripts and assets in angular.json

Now open the angular.json file and add the following under architect.build.assets for default project

{
  ...
  "build": {
    "builder": "@angular-devkit/build-angular:browser",
    "options": {
      ...
      ...
      "aot": false,
      "assets": [
        ...
        ...
+        {
+          "glob": "**/*",
+          "input": "node_modules/@project-sunbird/sunbird-questionset-editor/lib/assets",
+          "output": "/assets/"
+        },
+        {
+          "glob": "**/*",
+          "input": "node_modules/@project-sunbird/sunbird-quml-player-web-component/assets/",
+          "output": "/assets/"
+        }
      ],
      "styles": [
        ...
+        "node_modules/@project-sunbird/sunbird-quml-player-web-component/styles.css",
+        "node_modules/@project-sunbird/sb-styles/assets/_styles.scss",
+        "src/assets/lib/semantic/semantic.min.css",
+        "src/assets/styles/styles.scss",
+        "node_modules/font-awesome/css/font-awesome.css"
      ],
      "scripts": [
        ...
+        "node_modules/@project-sunbird/sunbird-quml-player-web-component/sunbird-quml-player.js",
+        "src/assets/libs/iziToast/iziToast.min.js",
+        "node_modules/jquery.fancytree/dist/jquery.fancytree-all-deps.min.js",
+        "src/assets/lib/dimmer.min.js",
+        "src/assets/lib/transition.min.js",
+        "src/assets/lib/modal.min.js",
+        "src/assets/lib/semantic-ui-tree-picker.js",
+        "node_modules/@project-sunbird/telemetry-sdk/index.js",
+        "node_modules/@project-sunbird/client-services/index.js"
      ]
    }
  }
  ...
  ...
}

🏷️ Step 4: Change in package.json

{
    ...
    ...
    "scripts": {
      "ng": "ng",
+      "start": "ng serve --proxy-config proxy.conf.json",
      ...
      ...
    },
    ...
    "dependencies": {
    ...
    ...
    },
    "devDependencies": {
    ...
    ...
    }
  }

🏷️ Step 5: Add question-cursor-implementation.service

Create a question-cursor-implementation.service.ts in a project and which will implement the QuestionCursor and EditorCursor abstract class.
QuestionCursor and EditorCursor is an abstract class, exported from the library, which needs to be implemented. Basically it has some methods which should make an API request over HTTP

Let's create the question-cursor-implementation service by running the following command:

cd src/app
ng g service question-cursor-implementation

Now open app.module.ts file and import like this:

+ import { EditorCursor } from '@project-sunbird/sunbird-questionset-editor';
+ import { EditorCursorImplementationService } from './editor-cursor-implementation.service';

@NgModule({
  providers: [
+    { provide: EditorCursor, useExisting: EditorCursorImplementationService }
  ],
})
export class AppModule { }

For more information refer question-cursor-implementation.service.ts.

🏷️ Step 5: Import the modules and components

Include QuestionsetEditorLibraryModule in your app module:

  import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
+  import { QuestionsetEditorLibraryModule, EditorCursor } from '@project-sunbird/sunbird-questionset-editor';
  import { RouterModule } from '@angular/router';
  import { EditorCursorImplementationService } from './editor-cursor-implementation.service';

  @NgModule({
   ...

   imports: [ 
+      QuestionsetEditorLibraryModule,
      BrowserAnimationsModule,
      RouterModule.forRoot([])
      ],
   providers: [
    { provide: EditorCursor, useExisting: EditorCursorImplementationService }
   ]

   ...
  })

 export class AppModule { }

Once your library is imported, you can use its main component, lib-questionset-editor in your Angular application.

Add the tag to the app.component.html like so:

<lib-questionset-editor [editorConfig]="editorConfig" (editorEmitter)="editorEventListener($event)"></lib-questionset-editor>

🏷️ Step 6: Send input to render QuestionSet Editor

Create a data.ts file which contains the questionSetEditorConfig Refer: data.ts

(Note: data.ts contains the mock config used in component to send it as input to questionset Editor. We need only questionSetEditorConfig.Use the mock config in your component to send input to questionset editor as editorConfig)

app.component.ts

   ...
+  import { questionSetEditorConfig } from './data';
   @Component({
     ...
   })
   export class AppComponent {
     ...
+     public editorConfig: any = questionSetEditorConfig;
   }

app.component.html

<lib-questionset-editor [editorConfig]="editorConfig" (editorEmitter)="editorEventListener($event)"></lib-questionset-editor>

🟠 Available components

Feature	Notes	Selector	Code	Input	Output
QuestionSet Editor	Can be used to render Editor	lib-questionset-editor	`<lib-questionset-editor [editorConfig]="editorConfig"></lib-questionset-editor>`	editorConfig	editorEmitter

🔻 Input Parameters

editorConfig: Object - [Required]

{
  context: Object   // Information about the telemetry and default settings for editor API requests
  config: Object    // default editor config such as sidebar menu list
}

For more information refer this documentation: CONFIGURATION.MD

🔻 Output Events

editorEmitter() - It emits event for each action performed in the editor.

🏷️Step 7: Set the auth token and questionset identifier

From the root directory - go to server.js file

Update the host variable to which env your pointing. example if you are pointing sunbird dev instance update variable like below
const BASE_URL = 'dev.sunbirded.org'
const API_AUTH_TOKEN = 'XXXX'
const USER_TOKEN= 'YYYY

Note: You will need actual API_AUTH_TOKEN and USER_TOKEN

If you are pointing to sunbird dev (dev.sunbirded.org), create a Question Set in sunbird dev, set the do_id of Question Set in data.ts file

export const questionSetEditorConfig = {
  context: {
    ...
    ...
    ...
    },
    identifier: 'do_id', // identifier of questionset created in sunbird dev
    ...
    ...
  };

🏷️ Step 8: Build the library

Run npm run build-lib to build the library. The build artifacts will be stored in the dist/ directory.

🏷️ Step 9: Run the application

Before running the application, we have to start the node server to proxy the APIs by running the following command:

nodemon server.js

Once that is done, Use the following CLI command to run your application locally

npm run start

To see your application in the browser, go to http://localhost:4200.
