Example 1: Custom Chart

Description

In this example, we create a custom state that shows a chart with an overview of all objects in the system. The resulting doughnut chart is clickable to drill down into the specific object types.

Implementation

  1. Use a CLI command to generate a state component with a custom name and sidebar link. The link appears in the navigation menu on the left. (sidebar-navigation = default)

    Code Block
    languagebash
    linenumberstrue
    eo g state custom


  2. Use a CLI command to install the maps package (takes some time).

    Code Block
    languagebash
    linenumberstrue
    npm install -P ng2-charts@1.6.0


  3. Import ChartsModule module to CustomStatesModule.

    Code Block
    languagejs
    titlecustom-states.module.ts
    linenumberstrue
    import {NgModule} from '@angular/core';
    import {CommonModule} from '@angular/common';
    import {Route, RouterModule} from '@angular/router';
    import {EoFrameworkModule} from '@eo-sdk/client';
    import {EoLinkPlugin} from '@eo-sdk/client';
    import {AuthGuard} from '@eo-sdk/client';
    import {CustomComponent} from './custom/custom.component';
    import {ChartsModule} from 'ng2-charts';
    
    export const routes: Route[] = [
      {path: CustomComponent.path, component: CustomComponent, canActivate: [AuthGuard]},
    ];
    
    export const links: EoLinkPlugin[] = [
      CustomComponent
    ];
    
    @NgModule({
      imports: [
        CommonModule,
        EoFrameworkModule,
        RouterModule.forChild(routes),
        ChartsModule
      ],
      declarations: [CustomComponent]
    })
    export class CustomStatesModule {
    }


  4. Update custom.component.ts to load current chart data.

    Code Block
    languagejs
    titlecustom.component.ts
    linenumberstrue
    import {Component, ViewChild} from '@angular/core';
    import {Chart} from 'chart.js';
    import {TranslateService, SearchService} from '@eo-sdk/core';
    import {BaseChartDirective} from 'ng2-charts';
    import {AppSearchService, UnsubscribeOnDestroy} from '@eo-sdk/client';
    import {takeUntil} from 'rxjs/operators';
    
    @Component({
      selector: 'eo-custom',
      templateUrl: './custom.component.html',
      styleUrls: ['./custom.component.scss']
    })
    export class CustomComponent extends UnsubscribeOnDestroy {
    
      static id = 'eo.custom.state.custom';
      static path = 'custom/custom';
      static matchType = new RegExp('sidebar-navigation');
    
      groupCount: number;
      totalCount: number;
      chart;
      activeType = 0;
      types = [];
    
      @ViewChild(BaseChartDirective) chartEl: BaseChartDirective;
    
      constructor(private translate: TranslateService,
                  private searchService: SearchService,
                  private appSearchService: AppSearchService) {
        super();
        this.fetchData();
      }
    
      chartClicked(el?) {
        if (!el || (this.activeType === this.groupCount && el.active[0])) {
          this.activeType = el ? el.active[0]._index : this.groupCount;
          this.chart = this.dataToChart(this.types[this.activeType]);
          setTimeout(() => {
            this.chartEl.chart.config.data.labels = this.chart.labels;
            this.chartEl.chart.update();
          }, 0);
        }
      }
    
      dataToChart(groups: any[]): Chart {
        return {
          data: [{
            data: groups.map(g => g.count),
            label: ''
          }],
          labels: groups.map(g => g.label)
        };
      }
    
    
      private fetchData() {
        this.appSearchService.setTerm('');
        this.appSearchService
          .queryState$
          .pipe(
            takeUntil(this.componentDestroyed$)
          )
          .subscribe(res => {
              this.totalCount = res.count;
              this.groupCount = this.appSearchService.objectTypeGroups.length;
              this.types = [];
    
              const main = this.appSearchService.objectTypeGroups.map((g) => {
                const type = g.types.map(t => ({label: t.label, count: res.aggregations.type.get(t.qname) || 0}));
                this.types.push(type.sort((a, b) => b.count - a.count));
                return {
                  label: g.label === '0' ? this.translate.instant('eo.quicksearch.result.group.global') : g.label,
                  count: type.map(t => t.count).reduce((a, b) => a + b, 0)
                };
              });
    
              this.types.push(main.sort((a, b) => b.count - a.count));
              this.chartClicked();
            }
          );
      }
    }
    


  5. Update custom-state.component.html to include a chart component.

    Code Block
    languagexml
    titlecustom-state.component.html
    linenumberstrue
    <button class="summary" (click)="chartClicked()">
      <span class="label" *ngIf="activeType != groupCount">{{types[groupCount][activeType].label}}: &nbsp;</span>
      <span class="count" *ngIf="activeType != groupCount"> {{types[groupCount][activeType].count}} of &nbsp;</span>
      <span class="total">{{totalCount}}</span>
    </button>
    
    <div class="chart-container">
      <canvas baseChart *ngIf="chart" height="100%"
              [datasets]="chart.data"
              [labels]="chart.labels"
              [chartType]="'doughnut'"
              (chartClick)="chartClicked($event)"></canvas>
    </div>


  6. To finish this state, add some styling

    Code Block
    languagecss
    titlecustom-state.component.scss
    linenumberstrue
    :host {
      flex: 1;
      display: flex;
      flex-flow: column;
    
      .summary {
        align-items: baseline;
        position: absolute;
        right: 30px;
        top: 30px;
        flex: 1 1 auto;
        display: flex;
        background: papayawhip;
        border-radius: 4px;
        padding: 16px;
        border: 1px solid rgba(255, 255, 255, 0.2);
    
        .label {
          font-size: 1.5em;
        }
        .count {
          font-size: 2.5em;
        }
        .total {
          font-size: 3.5em;
        }
    
      }
      .chart-container {
        flex: 0 0 auto;
      }
    }


  7. Use a CLI command to generate labels/translations.

    Code Block
    languagebash
    linenumberstrue
    eo g label eo.custom.state.custom --en "Custom state" --de "Custom state"


Example 2: Full screen State + Result List + Content Preview

Description

This example provides two new states. The first one shows the search result list in full screen, outside the usual client context. The second one shows the content preview of an object, also in full screen.


Implementation

  1. Use a CLI command to generate a simple preview state component. The link appears in the navigation menu on the left. (sidebar-navigation = default)

    Code Block
    languagebash
    titleTerminal
    eo g state simple-preview


  2. Update the simple-preview component implementation. Please update queryParams based on your scheme!

    Code Block
    languagexml
    titlesimple-preview.component.html
    <eo-media *ngIf="item"
              [dmsObject]="item"
              [useVersion]="item.id === item.content?.id"
              #viewer>
    </eo-media>
    


    Code Block
    languagecss
    titlesimple-preview.component.scss
    /* fullscreen setup */
    :host {
      position: fixed !important;
      top: 0;
      right: 0;
      bottom: 0;
      left: 0;
      z-index: 10 !important;
    }


    Code Block
    languagejs
    titlesimple-preview.component.ts
    import {Component, OnInit} from '@angular/core';
    import {DmsObject, DmsParams, DmsService} from '@eo-sdk/core';
    import {ActivatedRoute} from '@angular/router';
    import {UnsubscribeOnDestroy} from '@eo-sdk/client';
    import {takeUntil, filter} from 'rxjs/operators';
    
    @Component({
      selector: 'eo-simple-preview',
      templateUrl: './simple-preview.component.html',
      styleUrls: ['./simple-preview.component.scss']
    })
    export class SimplePreviewComponent extends UnsubscribeOnDestroy implements OnInit {
    
      static id = 'eo.custom.state.simple-preview';
      static path = 'custom/simple-preview';
      static matchType = new RegExp('sidebar-navigation');
    
      /* set specific existing ID of DMS object to provide correct link */
      static queryParams = {id: '0000'};
    
      item: DmsObject;
    
      constructor(private dmsService: DmsService, private route: ActivatedRoute) {
        super();
      }
    
      loadDmsObject(params: DmsParams) {
        this.dmsService
          .getDmsObjectByParams(params)
          .subscribe(val => this.item = val)
      }
    
      ngOnInit() {
        this.route
          .queryParams
          .pipe(takeUntil(this.componentDestroyed$), filter(params => params.id))
          .subscribe(params => this.loadDmsObject(params as DmsParams));
      }
    
    }
    


  3. Use a CLI command to generate a simple list state component. The link appears in the navigation menu on the left. (sidebar-navigation = default)

    Code Block
    languagebash
    titleTerminal
    eo g state simple-list


  4. Update the simple-list component implementation (a double-click redirects to the simple preview state). Please update queryParams based on your scheme!

    Code Block
    languagexml
    titlesimple-list.component.html
    <eo-result-list [query]="query" [hasIcon]="true" (onDoubleClick)="onDoubleClick($event)"></eo-result-list>
    


    Code Block
    languagecss
    titlesimple-list.component.scss
    /* fullscreen setup */
    :host {
      position: fixed !important;
      top: 0;
      right: 0;
      bottom: 0;
      left: 0;
      z-index: 10 !important;
    }


    Code Block
    languagejs
    titlesimple-list.component.ts
    import {Component, OnInit} from '@angular/core';
    import {SearchService, SearchQuery, SearchResult} from '@eo-sdk/core';
    import {ActivatedRoute, Router, NavigationExtras} from '@angular/router';
    import {takeUntil, filter} from 'rxjs/operators';
    import {UnsubscribeOnDestroy} from '@eo-sdk/client';
    import {SimplePreviewComponent} from '../simple-preview/simple-preview.component';
    
    @Component({
      selector: 'eo-simple-list',
      templateUrl: './simple-list.component.html',
      styleUrls: ['./simple-list.component.scss']
    })
    export class SimpleListComponent extends UnsubscribeOnDestroy implements OnInit {
    
      static id = 'eo.custom.state.simple-list';
      static path = 'custom/simple-list';
      static matchType = new RegExp('sidebar-navigation');
    
      /* set specific existing query to provide correct link */
      /* multiple ways how to set query based on input format */
      // static queryParams = {query : '%7B%22types%22%3A%5B%22eoxemail%22%5D%7D'};
      // static queryParams = {query : decodeURIComponent('%257B%2522types%2522%253A%255B%2522eoxemail%2522%255D%257D')};
      static queryParams = {query: encodeURIComponent(JSON.stringify({'types': ['eoxemail']}))};
    
      query: SearchQuery;
      searchResult: SearchResult = new SearchResult();
    
      constructor(private route: ActivatedRoute,
                  private router: Router,
                  private searchService: SearchService) {
        super();
      }
    
    
      getParams() {
        this.route
          .queryParams
          .pipe(takeUntil(this.componentDestroyed$), filter(params => params.query))
          .subscribe((params: any) => {
            this.query = JSON.parse(decodeURIComponent(params.query));
            const defaultQuery = this.searchService.buildQuery(this.query);
    
            this.searchService
              .getChunkedResult(defaultQuery, 0, 10000)
              .subscribe(result => {
                this.searchResult = result;
              });
          });
      }
    
      onDoubleClick(event) {
        const {id, version, typeName} = event.data;
        const queryParams: NavigationExtras = {queryParams: {id, version, 'type': typeName}};
        const url = this.router.createUrlTree([SimplePreviewComponent.path], queryParams).toString();
        window.open(url);
    
      }
    
      ngOnInit() {
        this.getParams();
      }
    
    }
    


  5. We need to generate a guard to deactivate the original behavior of the result list component

    Code Block
    languagebash
    titleTerminal
    ng generate guard eo-custom-client/custom-states/simple-list/can-deactivate-list --spec false


  6. Update can-deactivate-list.guard.ts

    Code Block
    languagejs
    titlecan-deactivate-list.guard.ts
    linenumberstrue
    import {Injectable} from '@angular/core';
    import {CanDeactivate} from '@angular/router';
    import {SimpleListComponent} from './simple-list.component';
    
    @Injectable({
      providedIn: 'root'
    })
    export class CanDeactivateListGuard implements CanDeactivate<SimpleListComponent> {
      canDeactivate() {
        return false;
      }
    }
    
    


  7. Add CanDeactivateListGuard guard to the custom-states module.

    Code Block
    languagejs
    titlecustom-states.module.ts
    linenumberstrue
    import {NgModule} from '@angular/core';
    import {CommonModule} from '@angular/common';
    import {Route, RouterModule} from '@angular/router';
    import {EoFrameworkModule} from '@eo-sdk/client';
    import {EoLinkPlugin} from '@eo-sdk/client';
    import {AuthGuard} from '@eo-sdk/client';
    import {SimpleListComponent} from './simple-list/simple-list.component';
    import {CanDeactivateListGuard} from './simple-list/can-deactivate-list.guard';
    import {SimplePreviewComponent} from './simple-preview/simple-preview.component';
    
    export const routes: Route[] = [
      {path: SimplePreviewComponent.path, component: SimplePreviewComponent, canActivate: [AuthGuard]},
      {path: SimpleListComponent.path, component: SimpleListComponent, canActivate: [AuthGuard], canDeactivate: [CanDeactivateListGuard]},
    ];
    
    export const links: EoLinkPlugin[] = [
      SimplePreviewComponent,
      SimpleListComponent,
    ];
    
    @NgModule({
      imports: [
        CommonModule,
        EoFrameworkModule,
        RouterModule.forChild(routes)
      ],
      declarations: [SimpleListComponent, SimplePreviewComponent]
    })
    export class CustomStatesModule {
    }
    
    


  8. Use a CLI command to generate labels/translations.

    Code Block
    languagebash
    linenumberstrue
    eo g label eo.custom.state.simple-list --en "Simple List" --de "Einfache Liste"


    Code Block
    languagebash
    linenumberstrue
    eo g label eo.custom.state.simple-preview --en "Simple Preview" --de "Einfache Vorschau"


Example 3: Custom Gallery State and Action

Description

In this example, we add a new custom action that opens an image gallery.

Implementation

  1. Use a CLI command to generate a state component.

    Code Block
    languagebash
    linenumberstrue
    eo g state gallery


  2. Use a CLI command to install the gallery package and hammerjs as dependency (takes some time).

    Code Block
    languagebash
    linenumberstrue
    npm install -P @ngx-gallery/core
    npm install -P hammerjs


  3. Import GalleryModule module and hammerjs to CustomStatesModule.

    Code Block
    languagejs
    titlecustom-states.module.ts
    linenumberstrue
    import {NgModule} from '@angular/core';
    import {CommonModule} from '@angular/common';
    import {Route, RouterModule} from '@angular/router';
    import {EoFrameworkModule} from '@eo-sdk/client';
    import {EoLinkPlugin} from '@eo-sdk/client';
    import {AuthGuard} from '@eo-sdk/client';
    import {GalleryComponent} from './gallery/gallery.component';
    import {GalleryModule} from '@ngx-gallery/core';
    import 'hammerjs';
    
    export const routes: Route[] = [
      {path: GalleryComponent.path, component: GalleryComponent, canActivate: [AuthGuard]},
    ];
    
    export const links: EoLinkPlugin[] = [
      GalleryComponent,
    ];
    
    @NgModule({
      imports: [
        CommonModule,
        EoFrameworkModule,
        GalleryModule.withConfig({
          gestures:false
        }),
        RouterModule.forChild(routes)
      ],
      declarations: [GalleryComponent]
    })
    export class CustomStatesModule {
    }
    
    


  4. Update gallery.component.ts to load files/images.

    Code Block
    languagejs
    titlegallery.component.ts
    linenumberstrue
    import {Component, OnInit} from '@angular/core';
    import {ActivatedRoute} from '@angular/router';
    import {DmsService} from '@eo-sdk/core';
    import {GalleryItem, ImageItem} from '@ngx-gallery/core';
    
    @Component({
      selector: 'eo-gallery',
      templateUrl: './gallery.component.html',
      styleUrls: ['./gallery.component.scss']
    })
    export class GalleryComponent implements OnInit {
    
      static id = 'eo.custom.state.gallery';
      static path = 'custom/gallery';
      // to hide link from sidebar-navigation just change matchType to non existing state
      static matchType = new RegExp('sidebar-navigation.no-link');
    
      images: GalleryItem[] = [];
    
      constructor(private route: ActivatedRoute, private dmsService: DmsService) {
      }
    
      ngOnInit() {
    
        const files = (this.route.snapshot.queryParams['files'] || '').split(',');
    
        this.images = files.map(id => new ImageItem({
            src: this.dmsService.getPreview(id),
            thumb: this.dmsService.getSlide(id)
          }));
      }
    
    }
    
    


  5. Update gallery.component.html to include a gallery component.

    Code Block
    languagexml
    titlegallery.component.html
    linenumberstrue
    <gallery [items]="images" [gestures]="false" *ngIf="images.length"></gallery>


  6. To finish this state, add some styling.

    Code Block
    languagecss
    titlegallery.component.scss
    linenumberstrue
    :host {
      display: block;
      height: 100%;
      gallery {
        height: 100%;
      }
    }


  7. Use a CLI command to generate an action component.

    Code Block
    languagebash
    linenumberstrue
    eo g action open-in-gallery


  8. Update open-in-gallery.component.ts to enable a redirect to the gallery state.

    Code Block
    languagejs
    titleopen-in-gallery.component.ts
    linenumberstrue
    import {Component} from '@angular/core';
    import {of as observableOf} from 'rxjs';
    import {Router} from '@angular/router';
    import {DmsObjectTarget, SelectionRange, SimpleAction} from '@eo-sdk/client';
    import {DmsObject, TranslateService} from '@eo-sdk/core';
    
    @Component({
      selector: 'eo-open-in-gallery',
      template: ``,
      styles: []
    })
    export class OpenInGalleryComponent extends DmsObjectTarget implements SimpleAction {
    
      label: string;
      description: string;
      priority = 0;
      iconSrc = 'assets/_default/svg/ic_finalized.svg';
      group = 'common';
      range = SelectionRange.MULTI_SELECT;
    
      constructor(private translate: TranslateService,
                  private router: Router) {
        super();
        this.label = this.translate.instant('eo.custom.action.gallery');
        this.description = this.translate.instant('eo.custom.action.gallery');
      }
    
      isExecutable(item: DmsObject) {
        return observableOf(item.content && item.content.contents && item.content.contents[0].mimetype.match(/^image/));
      }
    
      run(selection: DmsObject[]) {
        const queryParams = selection.map(i => i.id).join(',');
        this.router.navigate(['custom/gallery'], {queryParams: {files: queryParams}});
      }
