insights - Algolia

Signature

import {
  createInsightsMiddleware
} from "instantsearch.js/es/middlewares";

createInsightsMiddleware({
  insightsClient: null | InsightsClient,
  insightsInitParams?: object,
  onEvent?: (event: InsightsEvent, aa: null | InsightsClient) => void,
});

Starting from v4.9.0, you can use the insights option instead of setting up the Insights middleware yourself.

The createInsightsMiddleware creates an insights middleware to help you achieve the following:

Set the userToken for insights purposes (Click Analytics, Personalization, etc.)
Automatically send events from built-in widgets. You can turn this off if needed
Send events from your own custom widgets

Requirements

search-insights v1.6.2 or later.
Vue InstantSearch v3.7.0 or later.

Examples

JavaScript

import { createInsightsMiddleware } from "instantsearch.js/es/middlewares";

createInsightsMiddleware({
  insightsClient,
  insightsInitParams,
  onEvent,
});

Options

insightsClient

InsightsClient | null

The Insights client is used to send events. It synchronizes the user token between search and analytics calls.To disable userToken synchronization and automatic event sending, set this to null.

  }
</script>

insightsInitParams

object

Insights parameters to forward to the Insights client’s init method.With search-insights >= v1.7.0 and < 2.0.0, the Insights client accepts useCookie and userToken parameters in the init method. You can pass useCookie: false to prevent the usage of cookies to store an anonymous userToken. You can also pass a custom userToken while creating insights middleware, if you have one.With search-insights >= 2.0.0, the default value of useCookie is false.

You can set an authenticated user token and a user token in insightsInitParams. Both tokens are passed to the Insights API for sending events. If both are set, InstantSearch uses the authenticated user token for search queries.

createInsightsMiddleware({
  insightsInitParams: {
    useCookie: true,
  },
});

createInsightsMiddleware({
  insightsInitParams: {
    userToken: "user-token",
    authenticatedUserToken: "auth-user-token",
  },
});

onEvent

(event: InsightsEvent, aa: null | InsightsClient) => void

default:"undefined"

By default, the middleware sends events to Algolia using the provided insightsClient. You can also control events and send them yourself by implementing an onEvent method for the middleware to call instead. This method lets you access data and filter or modify the payload. You can also use it to send events to third-party trackers.If you want to use onEvent to send events to third-party trackers, but don’t want to send them to Algolia, you can set insightsClient to null, and you don’t need the search-insights library in your application.

Show event properties

event.insightsMethod

string

The Insights method, such as, 'viewedObjectIDs', 'clickedObjectIDsAfterSearch'. For more information, see the Insights API reference.

event.payload

[key: string]: any

Event payload.

Widget type given by connectors, such as 'ais.refinementList or 'ais.hits.

event.eventType

string

Event type, such as 'view', 'click', 'conversion', or anything else if you customized it.

JavaScript

createInsightsMiddleware({
  insightsClient: window.aa,
  onEvent: (event, aa) => {
    const { insightsMethod, payload, widgetType, eventType } = event;

    // Send the event to Algolia
    if (insightsMethod) {
      aa(insightsMethod, payload);
    }

    // Send the event to a third-party tracker
    if (widgetType === "ais.hits" && eventType === "click") {
      thirdPartyTracker.send("Product Clicked", payload);
    }
  },
});

Custom events

Connectors

Many of the InstantSearch connectors expose the sendEvent method. If you use these connectors to create custom widgets, you can leverage the method to send custom events.Here’s a list of connectors that expose sendEvent and they’re exposed at the default slot of corresponding Vue InstantSearch components.

connectAutocomplete: ais-autocomplete
connectHierarchicalMenu: ais-hierarchical-menu
connectHits: ais-hits
connectInfiniteHits: ais-infinite-hits
connectMenu: ais-menu and ais-menu-select
connectNumericMenu: ais-numeric-menu *
connectRange: ais-range-input *
connectRatingMenu: ais-rating-menu *
connectRefinementList: ais-refinement-list
connectToggleRefinement: ais-toggle-refinement

The sendEvent method provided to connectNumericMenu, connectRange, and connectRatingMenu can’t be used to send clicked filter events.

Vue

<ais-hits>
  <template v-slot="{ items, sendEvent }">
    <ul>
      <li v-for="item in items" :key="item.objectID">
        <p>{{ item.name }}</p>
        <button
          type="button"
          @click="sendEvent('click', item, 'Item Starred')"
        >
          Star
        </button>

        <button
          type="button"
          @click="sendEvent('conversion', item, 'Item Ordered')"
        >
          Order
        </button>
      </li>
    </ul>
  </template>
</ais-hits>
