Initialize

`buildInsightEngine`

Creates an insight engine instance.

Parameters

options: InsightEngineOptions

The insight engine options.

Returns InsightEngine

`InsightEngineOptions`

The insight engine options.

Properties

configuration: InsightEngineConfiguration

The insight engine configuration options.
loggerOptions?: LoggerOptions

The logger options.
middlewares?: Middleware<{}, State>[]

List of additional middlewares. A middleware is a higher-order function that composes a dispatch function to return a new dispatch function. It is useful for logging actions, performing side effects like routing, or turning an asynchronous API call into a series of synchronous actions.
navigatorContextProvider?: NavigatorContextProvider

An optional function returning navigation context. (referer, location, UserAgent)
preloadedState?: State

The initial headless state. You may optionally specify it to hydrate the state from the server in universal apps, or to restore a previously serialized user session.

`InsightEngineConfiguration`

The insight engine configuration options.

Properties

insightId: string

Specifies the unique identifier of the target insight configuration.
search?: InsightEngineSearchConfigurationOptions

Specifies the configuration for the insight search.
accessToken: string

The access token to use to authenticate requests against the Coveo Cloud endpoints. Typically, this will be an API key or search token that grants the privileges to execute queries and push usage analytics data in the target Coveo Cloud organization.
organizationId: string

The unique identifier of the target Coveo Cloud organization (e.g., mycoveocloudorganizationg8tp8wu3)
analytics?: AnalyticsConfiguration

Allows configuring options related to analytics.
name?: string

The Engine name (e.g., myEngine). Specifying your Engine name will help in debugging when using an application with multiple Redux stores.

Default: 'coveo-headless'
organizationEndpoints?: OrganizationEndpoints

The endpoints to use.

For example: https://orgid.org.coveo.com

The getOrganizationEndpoints helper function can be useful to create the appropriate object.

We recommend using this option, since it has resiliency benefits and simplifies the overall configuration for multi-region deployments. See Organization endpoints.
platformUrl?: string

The Platform URL to use. (e.g., https://platform.cloud.coveo.com) The platformUrl() helper method can be useful to know what url is available.
preprocessRequest?: PreprocessRequest

Allows for augmenting a Platform request before it is sent.
renewAccessToken?: () => Promise<string>

A function that fetches a new access token. The function must return a Promise that resolves to a string (the new access token).

`LoggerOptions`

The logger options.

Properties

browserPostLogHook?: (level: LogLevel, logEvent: LogEvent) => void

Function which will be called after writing the log message in the browser.
level?: LevelWithSilent

By default, is set to warn.
logFormatter?: (object: {}) => {}

Changes the shape of the log object. This function will be called every time one of the log methods (such as .info) is called. All arguments passed to the log method, except the message, will be pass to this function. By default it does not change the shape of the log object.

`Middleware<{}, State>[]`

List of additional middlewares. A middleware is a higher-order function that composes a dispatch function to return a new dispatch function. It is useful for logging actions, performing side effects like routing, or turning an asynchronous API call into a series of synchronous actions.

Properties

(call): (api: MiddlewareAPI<D, S>): (next: (action: unknown) => unknown) => (action: unknown) => unknown;

`InsightEngineSearchConfigurationOptions`

Specifies the configuration for the insight search.

Properties

locale?: string

The locale of the current user. Must comply with IETF’s BCP 47 definition: https://www.rfc-editor.org/rfc/bcp/bcp47.txt.

Notes: Coveo Machine Learning models use this information to provide contextually relevant output. Moreover, this information can be referred to in query expressions and QPL statements by using the $locale object.

`AnalyticsConfiguration`

Allows configuring options related to analytics.

Properties

analyticsClientMiddleware?: AnalyticsClientSendEventHook

analyticsClientMiddleware allows to hook into an analytics event payload before it is sent to the Coveo platform.
analyticsMode?: 'legacy' | 'next'

The analytics client to use.
- legacy: The legacy analytics client, i.e., the Coveo Analytics.js library.
- next: The next analytics client, i.e., the Coveo Event Protocol with the Relay library.
anonymous?: boolean

Whether analytics events should be logged anonymously. If set to true, the Usage Analytics Write API will not extract the name and userDisplayName, if present, from the search token
deviceId?: string

The name of the device that the end user is using. It should be explicitly configured in the context of a native mobile app.
documentLocation?: string

Specifies the URL of the current page or component.
enabled?: boolean

Specifies if usage analytics tracking should be enabled.

By default, all analytics events will be logged.
originContext?: string

Sets the Origin Context dimension on the analytics events.

You can use this dimension to specify the context of your application. The possible values are "Search", "InternalSearch", and "CommunitySearch".

The default value is Search.
originLevel2?: string

Sets the value of the Origin Level 2 dimension on the analytics events.

Origin level 2 is a usage analytics event metadata whose value should typically be the name/identifier of the tab from which the usage analytics event originates.

In the context of product listing, the value should match the breadcrumb of the product listing page from which the usage analytics event originates (for example, canoes-kayaks/kayaks/sea-kayaks).

When logging a usage analytics event, originLevel2 should always be set to the same value as the corresponding tab (parameter) Search API query parameter so Coveo Machine Learning models function properly, and usage analytics reports and dashboards are coherent.

If left unspecified, this value will automatically try to resolve itself from the tab Search API query parameter.
originLevel3?: string

Origin level 3 is a usage analytics event metadata whose value should typically be the URL of the page that linked to the search interface that’s making the request.

When logging a Search usage analytics event, originLevel3 should always be set to the same value as the corresponding referrer Search API query parameter so usage analytics reports and dashboards are coherent.

This value is optional, and will automatically try to resolve itself from the referrer search parameter.
runtimeEnvironment?: IRuntimeEnvironment

Optional analytics runtime environment, this is needed for analytics to work correctly if you’re running outside of a browser. See https://github.com/coveo/coveo.analytics.js for more info.
trackingId?: string

The unique identifier of the tracking target.
userDisplayName?: string

Specifies the user display name for the usage analytics logs.

`Unsubscribe`

Call signatures

(): void;

Methods

`executeFirstSearch`

Executes the first search.

Parameters

analyticsEvent: LegacySearchAction

The analytics event to log in association with the first search. If unspecified, logInsightInterfaceLoad will be used.

`addReducers`

Adds the specified reducers to the store.

Parameters

reducers: ReducersMapObject

An object containing the reducers to attach to the engine.

`disableAnalytics`

Disable analytics tracking

`enableAnalytics`

Enable analytics tracking

`subscribe`

Adds a change listener. It will be called any time an action is dispatched, and some part of the state tree may potentially have changed. You may then access the new state.
