Data Components

Reference for Spiderly's data table and data view components — paginated lists with filtering, sorting, selection, and Excel export.

Overview

Spiderly provides two components for displaying entity lists:

SpiderlyDataTable — paginated table with server-side filtering, sorting, row selection, and Excel export.
SpiderlyDataView — card-based list with filtering, useful for visual layouts.

Both support lazy loading (server-side pagination) and work with the generated API service methods.

SpiderlyDataTable

Selector: spiderly-data-table

Advanced paginated table with server-side filtering, sorting, selection, inline editing, and Excel export.

Key Inputs

Input	Type	Default	Description
`cols`	`Column[]`	—	Column definitions (see Column Configuration)
`getPaginatedListObservableMethod`	`(filter) => Observable<PaginatedResult>`	—	Server fetch method for lazy loading
`exportListToExcelObservableMethod`	`(filter) => Observable<any>`	—	Method called on "Export to Excel"
`deleteItemFromTableObservableMethod`	`(id) => Observable<any>`	—	Method called when a row is deleted
`rows`	`number`	config default	Page size
`rowsPerPageOptions`	`number[]`	config default	Page-size selector options
`selectionMode`	`'single' \| 'multiple'`	—	Row selection mode
`readonly`	`boolean`	`false`	Hides all action buttons
`hasLazyLoad`	`boolean`	`true`	`true` = server-side; `false` = client-side
`items`	`any[]`	—	Data rows (only when `hasLazyLoad` is `false`)
`showAddButton`	`boolean`	`true`	Show the "Add" button
`showExportToExcelButton`	`boolean`	`true`	Show the "Export" button
`navigateOnRowClick`	`boolean`	`false`	Clicking a row navigates to details
`additionalFilterIdLong`	`number`	—	Extra filter ID appended to every request

Key Outputs

Output	Payload	Description
`onLazyLoad`	`Filter`	Fires on every table load (sort, filter, page change)
`onTotalRecordsChange`	`number`	Fires when the total record count changes
`onRowSelect`	`RowClickEvent`	Fires when a row is selected
`onRowUnselect`	`RowClickEvent`	Fires when a row is deselected
`onIsAllSelectedChange`	`AllClickEvent`	Fires when the "select all" checkbox changes

Example

import { Component, OnInit } from '@angular/core';
import { TranslocoService } from '@jsverse/transloco';
import { Column, SpiderlyDataTableComponent } from 'spiderly';
import { ApiService } from 'src/app/business/services/api/api.service';

@Component({
  selector: 'product-list',
  templateUrl: './product-list.component.html',
  imports: [SpiderlyDataTableComponent],
})
export class ProductListComponent implements OnInit {
  cols: Column[];

  getProductTableDataObservableMethod = this.apiService.getProductPaginatedList;
  exportProductListToExcelObservableMethod = this.apiService.exportProductListToExcel;
  deleteProductObservableMethod = this.apiService.deleteProduct;

  constructor(
    private apiService: ApiService,
    private translocoService: TranslocoService,
  ) {}

  ngOnInit() {
    this.cols = [
      { name: this.translocoService.translate('Name'), field: 'name', filterType: 'text' },
      { name: this.translocoService.translate('Price'), field: 'price', filterType: 'numeric' },
      {
        name: this.translocoService.translate('CreatedAt'),
        field: 'createdAt',
        filterType: 'date',
        showMatchModes: true,
      },
    ];
  }
}

<spiderly-data-table
  [cols]="cols"
  [getPaginatedListObservableMethod]="getProductTableDataObservableMethod"
  [exportListToExcelObservableMethod]="exportProductListToExcelObservableMethod"
  [deleteItemFromTableObservableMethod]="deleteProductObservableMethod"
></spiderly-data-table>

Column Configuration

Columns are defined using the Column class. Each column maps to a data field and can have filtering, sorting, and custom actions.

Property	Type	Description
`name`	`string`	Column header label
`field`	`string`	Data field name (key from the DTO)
`filterType`	`'text' \| 'date' \| 'multiselect' \| 'boolean' \| 'numeric' \| 'blob'`	Type of column filter
`filterField`	`string`	Alternate field used for filtering (useful for FK autocomplete fields)
`showMatchModes`	`boolean`	Show match mode dropdown in the column filter
`dropdownOrMultiselectValues`	`PrimengOption[]`	Options for multiselect column filters
`editable`	`boolean`	Enable inline editing for this column
`showTime`	`boolean`	For date columns: show time portion
`decimalPlaces`	`number`	For numeric columns: decimal formatting
`actions`	`Action[]`	Row action buttons (see Actions)

Actions

Use the Action class to add buttons to each row:

{
  actions: [
    { field: 'Details', icon: 'pi pi-pencil' },
    { field: 'Delete', icon: 'pi pi-trash' },
    { field: 'custom', name: 'Preview', icon: 'pi pi-eye', onClick: (id) => this.preview(id) },
  ],
}

Built-in field values:

'Details' — navigates to the detail page
'Delete' — opens a confirmation dialog and calls deleteItemFromTableObservableMethod
Any other value — triggers the onClick callback

SpiderlyDataView

Selector: spiderly-data-view

Card-based paginated list with custom rendering and filtering. Use this when you want a visual layout instead of a table.

Key Inputs

Input	Type	Default	Description
`filters`	`DataViewFilter[]`	`[]`	Filter definitions displayed above the card list
`getPaginatedListObservableMethod`	`(filter) => Observable<PaginatedResult>`	—	Server fetch method
`rows`	`number`	`10`	Page size
`items`	`any[]`	—	Data items (only for non-lazy mode)

Key Outputs

Output	Payload	Description
`onLazyLoad`	`Filter`	Fires on every lazy load (page change, filter change)

Content Projection

Render each card using an ng-template with the #cardBody reference:

<spiderly-data-view
  [getPaginatedListObservableMethod]="getProductListObservableMethod"
  [filters]="filters"
>
  <ng-template #cardBody [templateType]="templateType" let-item let-index="index">
    <div class="p-4 border rounded">
      <h3>{{item.name}}</h3>
      <p>{{item.price | currency}}</p>
    </div>
  </ng-template>
</spiderly-data-view>

The template context provides item (the data object) and index (row index).

Example

import { Component, OnInit } from '@angular/core';
import { TranslocoService } from '@jsverse/transloco';
import { ApiService } from 'src/app/business/services/api/api.service';
import {
  DataViewFilter,
  DataViewCardBody,
  SpiderlyControlsModule,
  SpiderlyDataViewComponent,
  SpiderlyTemplateTypeDirective,
} from 'spiderly';

@Component({
  selector: 'product-data-view',
  templateUrl: './product-data-view.component.html',
  imports: [SpiderlyTemplateTypeDirective, SpiderlyDataViewComponent, SpiderlyControlsModule],
})
export class ProductDataViewComponent implements OnInit {
  templateType?: DataViewCardBody<Product>;
  filters: DataViewFilter<Product>[];

  getProductListObservableMethod = this.apiService.getProductPaginatedList;

  constructor(
    private apiService: ApiService,
    private translocoService: TranslocoService,
  ) {}

  ngOnInit() {
    this.filters = [
      { label: this.translocoService.translate('Name'), type: 'text', field: 'name' },
      {
        label: this.translocoService.translate('Price'),
        type: 'numeric',
        field: 'price',
        showMatchModes: true,
      },
      {
        label: this.translocoService.translate('CreatedAt'),
        type: 'date',
        field: 'createdAt',
        showMatchModes: true,
      },
    ];
  }
}
