This project was developed during Alfresco Global Virtual Hack-a-thon 2018

This project provides an extension for Alfresco Content Application 1.5.

A new Office button is added to Open with menu. When the button is clicked, Microsoft Office protocol is invoked so local Office Program is launched.

It's required an Alfresco Repository includig AOS feature properly configured.

Please also refer to the ACA Extensibility documentation.

This project contains:

• Blank Angular application
• AOS extension for ACA including a new Office button to Open with menu
• ADF dependencies (Extensions, Core and Content Services)
• Scripts to build, package and publish the extension

See also the official ACA Extension Sample from Alfresco.

Caution: Since ADF / ACA is evolving fast, this repository could be obsolete in the future.

This plugin includes a new Action for the feature Open With in the Viewer. You can find documentation related to Actions for ACA Extension at

https://alfresco.github.io/alfresco-content-app/#/extending?id=actions

Action configuration is performed on a JSON file following extension.schema.json specification. Following configuration has been defined for this plugin in aos.plugin.json file:

{
    "$schema": "../../../extension.schema.json",
    "$version": "1.0.0",
    "$name": "aos.plugin",
    "$description": "AOS Plugin",

    "actions": [
        {
            "id": "aos.plugin.actions.info",
            "type": "AOS_ACTION",
            "payload": "$(context.selection.first.entry)"
        }
    ],

    "features": {
        "viewer": {
            "openWith": [
                {
                    "id": "aos.plugin.viewer.openWith.action1",
                    "type": "button",
                    "icon": "build",
                    "title": "Office",
                    "actions": {
                        "click": "aos.plugin.actions.info"
                    }
                }
            ]
        }
    }
}

The action part includes the type AOS_ACTION and the payload. The type name is used to develop the Action and the Effect in Typescript. The payload can be any data value from any data type. It can be also an expression with the format $(<expresion>), as in the above sample, where a complex Entry object is sent in the payload.

The features part includes the feature type and also a block to include different actions. In this case, a click on the element will invoke aos.plugin.actions.info action.

To define the Action and the Payload type are defined as an @ngrx/store Action in aos.actions.ts

In this case $(context.selection.first.entry), the payload expression, is a MinimalNodeEntryEntity object from alfresco-js-api.

import { Action } from '@ngrx/store';
import { MinimalNodeEntryEntity } from 'alfresco-js-api';

export const AOS_ACTION = 'AOS_ACTION';

export class AosAction  implements Action {

	// Action Type
    readonly type = AOS_ACTION;

    // Payload Type
    constructor(public payload: MinimalNodeEntryEntity) {}
}

The Effect of the Action is defined in aos.effects.ts. In this case, the Action is calling to AosEditOnlineService.onActionEditOnlineAos() method, where the invocation to Office local program is performed.

import { Injectable } from '@angular/core';
import { Actions, Effect, ofType } from '@ngrx/effects';
import { map } from 'rxjs/operators';

import { AOS_ACTION, AosAction } from '../actions/aos.actions';
import { AosEditOnlineService } from '../aos-extension.service';

@Injectable()
export class AosEffects {
  constructor(
    private actions$: Actions,
    private aosEditOnlineService: AosEditOnlineService
  ) {}

  @Effect({ dispatch: false })
  openOffice$ = this.actions$.pipe(
    ofType<AosAction>(AOS_ACTION),
    map(action => {
      if (action.payload) {
        this.aosEditOnlineService.onActionEditOnlineAos(action.payload);
      }
    })
  );
}

After that, a module configuration including developed components, services and effects must be done at aos-extension.module.ts

import { ExtensionService } from '@alfresco/adf-extensions';
import { NgModule } from '@angular/core';
import { EffectsModule } from '@ngrx/effects';

import { AosExtensionComponent } from './aos-extension.component';
import { AosEditOnlineService } from './aos-extension.service';
import { AosEffects } from './effects/aos.effects';

@NgModule({
  imports: [
    EffectsModule.forRoot([AosEffects])
  ],
  declarations: [AosExtensionComponent],
  exports: [AosExtensionComponent],
  entryComponents: [AosExtensionComponent],
  providers: [ AosEditOnlineService]
})
export class AosExtensionModule {
  constructor(extensions: ExtensionService) {
    extensions.setComponents({
      'aos-edit-online.main.component': AosExtensionComponent
    });
  }
}

And finally a public declaration of elements to be used by other modules is done at public_api.ts

export * from './lib/aos-extension.service';
export * from './lib/aos-extension.component';
export * from './lib/aos-extension.module';
export * from './lib/actions/aos.actions';
export * from './lib/effects/aos.effects';

This plugin can be used by ACA as an extension from NPM or from local packaging.

$ npm run build:aos-extension

Build and package the extension library locally without publishing to NPM:

$ npm run package:aos-extension

The script produces the dist/aos-extension/aos-extension-0.0.1.tgz file that can be used to be installed as dependency.

Caution: Since ADF / ACA is evolving fast, following instructions could be different for your ACA version. This project has been developed by using a 1.5-beta version.

Download a new ACA project to integrate your extension.

$ wget https://github.com/Alfresco/alfresco-content-app/archive/development.zip
$ unzip development.zip
$ cd alfresco-content-app-development/

Install project dependencies and install also your extension into download ACA application.

$ npm install

$ npm i ../aca-extension-aos/dist/aos-extension/aos-extension-0.0.1.tgz

Update the extensions.module.ts file and append the module.

$ vi src/app/extensions.module.ts

import { AosExtensionModule } from 'aos-extension';

@NgModule({
  imports: [
    ...,
    AosExtensionModule
  ]
})
export class AppExtensionsModule {}

Update the app.extensions.json file and register new plugin

$ vi src/assets/app.extensions.json

{
  "$schema": "../../extension.schema.json",
  "$name": "app",
  "$version": "1.0.0",
  "$references": [
    ...,
    "aos.plugin.json"
  ],
}

Copy original plugin from extension dist/assets/aos.plugin.json to the ACA application src/assets/plugins folder.

$ cp ../dist/aos-extension/assets/aos.plugin.json src/assets/plugins

Run the ACA application

npm start

Depending on the setup, you might need to log in as an administrator and enable external plugins feature for your local run.
