useFailureEventTracker

Returns a ready-to-trigger trackFailureEvent by retrieving ReactNativeTracker instance and LocationStack automatically.

useFailureEventTracker = (
  hookParameters: {
    tracker?: Tracker,
    locationStack?: LocationStack,
    globalContexts?: GlobalContexts
  } = {}
) => (
  callbackParameters: {
    message: string,
    tracker?: Tracker,
    locationStack?: LocationStack,
    globalContexts?: GlobalContexts
  } = {}
) => Promise<TrackerEvent>

Parameters​

The hook and callback share tracker, locationStack and globalContexts parameters.

This allows composing the Event's payload by combining parameters provided to the hook and/or the callback:

  • tracker: Custom tracker instance. By default, useTracker() is used, which can be overridden by providing this parameter to the hook, or later to the callback. If both hook and callback have tracker parameters, the callback takes precedence.

  • locationStack: The callback and hook LocationStack are merged with the result of useLocationStack(). This allows to combine the LocationStack of parent components with the virtual Locations provided to either the hook or callback, or both.

  • globalContexts: The callback and hook GlobalContexts items are simply merged together.

Callback Parameters​

Returns​

A callback with the same parameters of the hook itself and an extra message parameter.

} = {}) => Promise<TrackerEvent>

Usage​

Scenario: form submit failure
import { useFailureEventTracker } from "@objectiv/tracker-react-native";

const trackFailureEvent = useFailureEventTracker();

submitFormData(formData)
  .catch((error) => {
    trackFailureEvent({
      message: error.message
    });
  });
Scenario: virtual location wrapper
import { makeContentContext } from "@objectiv/tracker-core";
import { useFailureEventTracker } from "@objectiv/tracker-react-native";

const trackFailureEvent = useFailureEventTracker();

submitFormData(formData)
  .catch((error) => {
    trackFailureEvent({
      locationStack: [
        makeContentContext({
          id: 'subscribe-view'
        })
      ],
      message: error.message
    });
  });
Scenario: additional global contexts representing form fields that did not validate
import { makeInputValueContext } from "@objectiv/tracker-core";
import { useFailureEventTracker } from "@objectiv/tracker-react-native";

const trackFailureEvent = useFailureEventTracker();

validateFields(formFields)
  .catch((errors) => {
    trackFailureEvent({
      globalContexts: [
        errors.map(({ fieldKey, fieldValue }) => {
          makeInputValueContext({
            id: fieldKey,
            // obfuscateFormField is a hypotethical function to obfuscate sensitive data
            value: obfuscateFormField(formFields, fieldKey)
          })
        })
      ],
      message: 'Validation Error'
    });
  });
