SystemJs

Add the following components to your systemjs.config.js file:
- ng2-translate
- alfresco-js-api
- ng2-alfresco-core
- ng2-alfresco-viewer
Please refer to the following example file: systemjs.config.js .

Basic usage with node id

<alfresco-viewer [overlayMode]="true" [urlFile]="'filename.pdf'"></alfresco-viewer>

Example of an App that declares the file viewer component :

import { NgModule, Component } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { CoreModule, AlfrescoSettingsService, AlfrescoAuthenticationService } from 'ng2-alfresco-core';
import { ViewerModule } from 'ng2-alfresco-viewer';

@Component({
    selector: 'alfresco-app-demo',
    template: `
        <alfresco-viewer 
            [showViewer]="true" 
            [overlayMode]="true" 
            [fileNodeId]="'d367023a-7ebe-4f3a-a7d0-4f27c43f1045'">
        </alfresco-viewer>`
})
class MyDemoApp {

    constructor(private authService: AlfrescoAuthenticationService, 
                private settingsService: AlfrescoSettingsService) {
        settingsService.ecmHost = 'http://localhost:8080';

        this.authService.login('admin', 'admin').subscribe(
            ticket => console.log(ticket),
            error => console.log(error)
        );
    }
}

@NgModule({
    imports: [
        BrowserModule,
        CoreModule.forRoot(),
        ViewerModule.forRoot()
    ],
    declarations: [ MyDemoApp ],
    bootstrap:    [ MyDemoApp ]
})
export class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

Basic usage with urlFile

<alfresco-viewer [overlayMode]="true" [urlFile]="'filename.pdf'"></alfresco-viewer>

Example of an App that declares the file viewer component :

import { NgModule, Component } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { CoreModule, AlfrescoSettingsService, AlfrescoAuthenticationService } from 'ng2-alfresco-core';
import { ViewerModule } from 'ng2-alfresco-viewer';

@Component({
    selector: 'alfresco-app-demo',
    template: `
        <alfresco-viewer 
            [showViewer]="true" 
            [overlayMode]="true" 
            [urlFile]="'localTestFile.pdf'">
        </alfresco-viewer>`
})
class MyDemoApp {

    constructor(private authService: AlfrescoAuthenticationService, 
                private settingsService: AlfrescoSettingsService) {
        settingsService.ecmHost = 'http://localhost:8080';
        this.authService.login('admin', 'admin').subscribe(
            ticket => console.log(ticket),
            error => console.log(error)
        );
    }
}

@NgModule({
    imports: [
        BrowserModule,
        CoreModule.forRoot(),
        ViewerModule.forRoot()
    ],
    declarations: [ MyDemoApp ],
    bootstrap:    [ MyDemoApp ]
})
export class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

Custom extension handler

If you want handle other file formats that are not yet supported by the ng2-alfresco-viewer you can define your own custom handler.

Below you can find an example where with the use of extension-viewer if you can handle 3d files

<alfresco-viewer 
    [(showViewer)]="fileShowed"
    [fileNodeId]="fileNodeId"
    [overlayMode]="true">
    
    <extension-viewer [supportedExtensions]="['obj','3ds']" #extension>
        <template let-urlFileContent="urlFileContent" let-extension="extension">
            <threed-viewer 
                [urlFile]="urlFileContent" 
                [extension]="extension">
            </threed-viewer>
        </template>
    </extension-viewer>

</alfresco-viewer>

Note: you need adding ng2-3d-editor dependency to your package.json file to make example above work.

It is possible to define multiple extension-viewer templates:

<alfresco-viewer 
    [(showViewer)]="fileShowed"
    [fileNodeId]="fileNodeId"
    [overlayMode]="true">

    <extension-viewer [supportedExtensions]="['xls','xlsx']" #extension>
        <template let-urlFileContent="urlFileContent"  >
            <my-custom-xls-component 
                urlFileContent="urlFileContent">
            </my-custom-xls-component>
        </template>
    </extension-viewer>

    <extension-viewer [supportedExtensions]="['txt']" #extension>
        <template  let-urlFileContent="urlFileContent" >               
            <my-custom-txt-component 
                urlFileContent="urlFileContent">
            </my-custom-txt-component>
        </template>
    </extension-viewer>
</alfresco-viewer>

Build from sources

Alternatively you can build component from sources with the following commands:

npm install
npm run build

Build the files and keep watching for changes

$ npm run build:w

Running unit tests

npm test

Running unit tests in browser

npm test-browser

This task rebuilds all the code, runs tslint, license checks and other quality check tools before performing unit testing.

Code coverage

npm run coverage

Demo

If you want have a demo of how the component works, please check the demo folder :

cd demo
npm install
npm start

NPM scripts
