<ng-ais-instantsearch />

Is the root component of all Angular InstantSearch implementations.

Attributes Type Description
config ConfigOptions The config object to pass to the instantsearch instance

Three parameters are required to get you started with instantsearch.js:

  • appId: your algolia application id
  • apiKey: the search key associated with your application
  • indexName: the main index that you will use for your new search UI

Those parameters can be found in your Algolia dashboard.

Example:

@Component({
  selector: 'ng-ais-app',
  template: `
    <ng-ais-instantsearch
      [config]="{
        apiKey: '6be0576ff61c053d5f9a3225e2a90f76',
        appId: 'latency',
        indexName: 'instant_search'
      }"
    >
    </ng-ais-instantsearch>
  `
})
export class AppComponent {}

ConfigOptions

appId: string

The Algolia application ID

apiKey: string

The Algolia search-only API key

indexName: string

The name of the main index

numberLocale?: string

The locale used to display numbers. This will be passed to Number.prototype.toLocaleString()

searchFunction?: Function

A hook that will be called each time a search needs to be done, with the helper as a parameter. It’s your responsibility to call helper.search(). This option allows you to avoid doing searches at page load for example.

createAlgoliaClient?: (algoliasearch: Function, appId: string, apiKey: string) => CustomClient

Allows you to provide your own algolia client instead of the one instantiated internally. Useful in situations where you need to setup complex mechanism on the client or if you need to share it easily. We forward algoliasearch which is the original algoliasearch module imported inside angular-instantsearch.

searchParameters?: {}

Additional parameters to pass to the Algolia API.

urlSync?: boolean | URLSyncOptions

Url synchronization configuration. Setting to true will synchronize the needed search parameters with the browser url.

URLSyncOptions

mapping?: {}

Object used to define replacement query parameter to use in place of another. Keys are current query parameters and value the new value, e.g. { q: 'query' }.

threshold?: number

Idle time in ms after which a new state is created in the browser history. The default value is 700. The url is always updated at each keystroke but we only create a “previous search state” (activated when click on back button) every 700ms of idle time.

trackedParameters?: string[]

Parameters that will be synchronized in the URL. Default value is ['query', 'attribute:\*', 'index', 'page', 'hitsPerPage']. attribute:* means all the faceting attributes will be tracked. You can track only some of them by using […, 'attribute:color', 'attribute:categories']. All other possible values are all the attributes of the Helper SearchParameters.

useHash?: boolean

If set to true, the url will be hash based. Otherwise, it’ll use the query parameters using the modern history API.

getHistoryState?: Function

Pass this function to override the default history API state we set to null. For example this could be used to force passing {turbolinks: true} to the history API every time we update it.

Events

You can register to the (change) event on the <ng-ais-instantsearch> which will be fired after every new search. This event is useful for instance to push data to Google Analytics to know more about your users search:

<ng-ais-instantsearch
  [config]="{...}"
  (change)="onSearchChange($event)"
>
</ng-ais-instantsearch>
onSearchChange({ results, state }: { results: {}, state: {} }) {
  // Do what ever you need with the results or the state of search
}
