Frigade has introduced a new feature in its @frigade/react library, version 1.38.8 and above, that simplifies the process of mapping data collected during a guest session to a registered user account, which is a typical requirement in product onboarding flows. Traditionally, this process required developers to create a custom datastore to track guest sessions, manage cookies or local storage for storing IDs, and write extensive code to map the session data to the database. However, Frigade's new functionality allows developers to achieve this with a single line of code using the linkExistingGuestSessionToUser method in the Flows Hook, streamlining the integration of unauthenticated user data with registered user accounts efficiently.
