# Querying Lists Easily with ListService |
||||
|
|
||||
|
`ListService` is a utility service to provide an easy pagination, sorting, and search implementation. |
||||
|
|
||||
|
|
||||
|
|
||||
|
## Getting Started |
||||
|
|
||||
|
`ListService` is **not provided in root**. The reason is, this way, it will clear any subscriptions on component destroy. You may use the optional `LIST_QUERY_DEBOUNCE_TIME` token to adjust the debounce behavior. |
||||
|
|
||||
|
```js |
||||
|
import { ListService } from '@abp/ng.core'; |
||||
|
import { BookDto } from '../models'; |
||||
|
import { BookService } from '../services'; |
||||
|
|
||||
|
@Component({ |
||||
|
/* class metadata here */ |
||||
|
providers: [ |
||||
|
// [Required] |
||||
|
ListService, |
||||
|
|
||||
|
// [Optional] |
||||
|
// Provide this token if you want a different debounce time. |
||||
|
// Default is 300. Cannot be 0. Any value below 100 is not recommended. |
||||
|
{ provide: LIST_QUERY_DEBOUNCE_TIME, useValue: 500 }, |
||||
|
], |
||||
|
template: ` |
||||
|
|
||||
|
`, |
||||
|
}) |
||||
|
class BookComponent { |
||||
|
items: BookDto[] = []; |
||||
|
count = 0; |
||||
|
|
||||
|
constructor( |
||||
|
public readonly list: ListService, |
||||
|
private bookService: BookService, |
||||
|
) {} |
||||
|
|
||||
|
ngOnInit() { |
||||
|
// A function that gets query and returns an observable |
||||
|
const bookStreamCreator = query => this.bookService.getList(query); |
||||
|
|
||||
|
this.list.hookToQuery(bookStreamCreator).subscribe( |
||||
|
response => { |
||||
|
this.items = response.items; |
||||
|
this.count = response.count; |
||||
|
// If you use OnPush change detection strategy, |
||||
|
// call detectChanges method of ChangeDetectorRef here. |
||||
|
} |
||||
|
); // Subscription is auto-cleared on destroy. |
||||
|
} |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
> Noticed `list` is `public` and `readonly`? That is because we will use `ListService` properties directly in the component's template. That may be considered as an anti-pattern, but it is much quicker to implement. You can always use public component properties instead. |
||||
|
|
||||
|
Place `ListService` properties into the template like this: |
||||
|
|
||||
|
```html |
||||
|
<abp-table |
||||
|
[value]="book.items" |
||||
|
[(page)]="list.page" |
||||
|
[rows]="list.maxResultCount" |
||||
|
[totalRecords]="book.totalCount" |
||||
|
[headerTemplate]="tableHeader" |
||||
|
[bodyTemplate]="tableBody" |
||||
|
[abpLoading]="list.isLoading$ | async" |
||||
|
> |
||||
|
</abp-table> |
||||
|
|
||||
|
<ng-template #tableHeader> |
||||
|
<tr> |
||||
|
<th (click)="nameSort.sort('name')"> |
||||
|
{%{{{ '::Name' | abpLocalization }}}%} |
||||
|
<abp-sort-order-icon |
||||
|
#nameSort |
||||
|
sortKey="name" |
||||
|
[(selectedSortKey)]="list.sortKey" |
||||
|
[(order)]="list.sortOrder" |
||||
|
></abp-sort-order-icon> |
||||
|
</th> |
||||
|
</tr> |
||||
|
</ng-template> |
||||
|
|
||||
|
<ng-template #tableBody let-data> |
||||
|
<tr> |
||||
|
<td>{%{{{ data.name }}}%}</td> |
||||
|
</tr> |
||||
|
</ng-template> |
||||
|
``` |
||||
|
|
||||
|
## Usage with Observables |
||||
|
|
||||
|
You may use observables in combination with [AsyncPipe](https://angular.io/guide/observables-in-angular#async-pipe) of Angular instead. Here are some possibilities: |
||||
|
|
||||
|
```ts |
||||
|
book$ = this.list.hookToQuery(query => this.bookService.getListByInput(query)); |
||||
|
``` |
||||
|
|
||||
|
```html |
||||
|
<!-- simplified representation of the template --> |
||||
|
|
||||
|
<abp-table |
||||
|
[value]="(book$ | async)?.items || []" |
||||
|
[totalRecords]="(book$ | async)?.totalCount" |
||||
|
> |
||||
|
</abp-table> |
||||
|
|
||||
|
<!-- DO NOT WORRY, ONLY ONE REQUEST WILL BE MADE --> |
||||
|
``` |
||||
|
|
||||
|
...or... |
||||
|
|
||||
|
|
||||
|
```ts |
||||
|
@Select(BookState.getBooks) |
||||
|
books$: Observable<BookDto[]>; |
||||
|
|
||||
|
@Select(BookState.getBookCount) |
||||
|
bookCount$: Observable<number>; |
||||
|
|
||||
|
ngOnInit() { |
||||
|
this.list.hookToQuery((query) => this.store.dispatch(new GetBooks(query))).subscribe(); |
||||
|
} |
||||
|
``` |
||||
|
|
||||
|
```html |
||||
|
<!-- simplified representation of the template --> |
||||
|
|
||||
|
<abp-table |
||||
|
[value]="books$ | async" |
||||
|
[totalRecords]="bookCount$ | async" |
||||
|
> |
||||
|
</abp-table> |
||||
|
``` |
||||
|
|
||||
|
## How to Refresh Table on Create/Update/Delete |
||||
|
|
||||
|
`ListService` exposes a `get` method to trigger a request with the current query. So, basically, whenever a create, update, or delete action resolves, you can call `this.list.get();` and it will call hooked stream creator again. |
||||
|
|
||||
|
```ts |
||||
|
this.store.dispatch(new DeleteBook(id)).subscribe(this.list.get); |
||||
|
``` |
||||
|
|
||||
|
...or... |
||||
|
|
||||
|
```ts |
||||
|
this.bookService.createByInput(form.value) |
||||
|
.subscribe(() => { |
||||
|
this.list.get(); |
||||
|
|
||||
|
// Other subscription logic here |
||||
|
}) |
||||
|
``` |
||||
|
|
||||
|
## How to Implement Server-Side Search in a Table |
||||
|
|
||||
|
`ListService` exposes a `filter` property that will trigger a request with the current query and the given search string. All you need to do is to bind it to an input element with two-way binding. |
||||
|
|
||||
|
```html |
||||
|
<!-- simplified representation --> |
||||
|
|
||||
|
<input type="text" name="search" [(ngModel)]="list.filter"> |
||||
|
``` |
