Identify Users (React Native)

Identifying your users helps you find you find their sessions in the LogRocket dashboard.

Call LogRocket.identify() on page loads to associate your own application-specific user ID with the active user. These user identifiers will be referred to as "UIDs".

LogRocket.identify(uid);

You can use any string that uniquely identifies the user of your application, such as a database ID, an email, or a username.

If you do not provide a UID, the user will be assigned a random one and shown as "Anonymous" in the UI.

LogRocket.identify('123456') // an immutable ID from your database (preferred)
LogRocket.identify('[email protected]') // the user's email

It's recommended to use an immutable database ID if available. Names and email addresses can be added as user traits as they could change.

Specify other user traits

Other user information can also be given. This information will not be displayed in the session list directly, but can used for searching through sessions using a User Traits filter. They will also be displayed in the user details section of the session playback.

LogRocket.identify('123456', {
  name: 'Jane Smith',
  email: '[email protected]',
  age: 43,
  favoriteColor: 'blue',
  currentSubscription: 'professional-plan',
});

Here are a few gotchas to avoid while using LogRocket.identify:

• LogRocket.identify only accepts strings as UIDs. Make sure to cast your UID to a string before calling this function.
• There is no need to call LogRocket.identify for anonymous or logged out users. We use sessionStorage to persist sessions across pages for logged-out users.
• If LogRocket.identify is called multiple times during a recording, you can search for any of the identified users in the session.

🚧

Custom user data is identified on the user and will be the same across all of their sessions. Use LogRocket.track() to add information to individual sessions.

🚧

When searching within LogRocket using the User Trait filter, please note that we limit the search to 512 characters. Any terms greater than this length will be discarded.
