​
Updating the user ID

User IDs are important for Frigade to keep track of your users. If you don’t provide a user ID, Frigade will generate a guest user id for you. User IDs can be provided at time of render in the <FrigadeProvider /> component or at any time using the setUserId method: 
import { useUser } from '@frigade/react';

const { setUserId } = useUser();

setUserId('1234');
If you want to set properties in the same call, you can do so by using the setUserIdWithProperties method: 
import { useUser } from '@frigade/react';

const { setUserIdWithProperties } = useUser();

setUserIdWithProperties('1234', {
  name: 'Christian Mathiesen',
  email: 'chris@frigade.com'
});

​
Adding user properties

import { useUser } from '@frigade/react';

const { addPropertiesToUser } = useUser();

addPropertiesToUser({
  name: 'Christian Mathiesen',
  email: 'christian@frigade.com'
});

​
Tracking events for the user

import { useUser } from '@frigade/react';

const { trackEventForUser } = useUser();

trackEventForUser('user-registered', {
  name: 'Christian Mathiesen'
});

​
Standardized fields

When setting user properties, Frigade automatically detects and stores the following fields on the user:
  • firstName
  • lastName
  • email
  • organization

​
Linking a guest session to a user

Frigade will generate a guest user ID for you if you do not provide a user id. This ID is stored in the user’s browser using localStorage. This allows unauthenticated users to have state in Frigade Flows and to be able to continue their session when they return to your application. Often it is useful to link a guest session to a user when they register or log in and transfer all state and data. The linkExistingGuestSessionToUser(userId: string) method enable this functionality for you: 
import { useUser } from '@frigade/react';

const { linkExistingGuestSessionToUser } = useUser();

// This will merge all state from the guest session to the user with the ID '1234'
linkExistingGuestSessionToUser('1234');
