Contains Collection Editor library components powered by angular. These components are designed to be used in the sunbirdEd portal and web portal to drive reusability, maintainability hence reducing the redundant development effort significantly.

This guide explains how to set up your Angular project to begin using the collection editor library. It includes information on prerequisites, installing editor library, and optionally displaying a sample editor library component in your application to verify your setup.

If you are new to Angular or getting started with a new Angular application, see Angular's full Getting Started Guide and Setting up your environment.

NOTE: @project-sunbird/[email protected].* versions will refer to angular 9 to 12 upgradation changes.

For existing applications, follow the steps below to begin using Collection editor library.

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

npm i @project-sunbird/sunbird-collection-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 common-form-elements-web-v9 --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 angular2-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-pdf-player-v9 --save
npm i @project-sunbird/sunbird-epub-player-v9 --save
npm i @project-sunbird/sunbird-video-player-v9 --save
npm i @project-sunbird/sunbird-quml-player --save

npm i @project-sunbird/sb-styles

Note: As Collection library is build with angular version 12, we are using [email protected] and [email protected] which are the compatible versions. For more reference Check compatibility document for ng-bootstrap here

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

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,

      ],
      "styles": [
        ...

      ],
      "scripts": [
        ...

      ]
    }
  }
  ...
  ...
}

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 'collection-editor-library';
+ import { QuestionCursor } from '@project-sunbird/sunbird-quml-player';
+ import { EditorCursorImplementationService } from './editor-cursor-implementation.service';

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

For more information refer question-cursor-implementation.service.ts and do not forgot to add your question list API URL For example: https://staging.sunbirded.org/api/question/v1/list

Include CollectionEditorLibraryModule in your app module:

  import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
+  import { CollectionEditorLibraryModule, EditorCursor } from '@project-sunbird/sunbird-collection-editor';
  import { RouterModule } from '@angular/router';
  import { QuestionCursor } from '@project-sunbird/sunbird-quml-player';
  import { EditorCursorImplementationService } from './editor-cursor-implementation.service';

  @NgModule({
   ...

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

   ...
  })

 export class AppModule { }

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

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

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

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

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

app.component.ts

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

app.component.html

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

1. 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

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

Go to the root directory - Open 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 textbook in sunbird dev, copy the textbook_id from the browser url and set the do_id of textbook in the data.ts file

export const collectionEditorConfig = {
  context: {
       ...
       identifier: 'do_id', // identifier of textbook created in sunbird dev
      ...
  },
  config: {
      ...
  }

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

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.
