useUser()
The useUser() hook is a convenient way to access the current User data where you need it. This hook provides the user data and helper methods to manage the current active session.
useUser() returns
| Name | Type | Description |
|---|---|---|
isSignedIn | boolean | A boolean that returns true if the user is signed in. |
isLoaded | boolean | A boolean that until Clerk loads and initializes, will be set to false. Once Clerk loads, isLoaded will be set to true. |
user | User | The User object for the currently active user. If the user is not signed in, user will be null. |
How to use the useUser() hook
Retrieve the current user data with the useUser() hook
The following example demonstrates how to use the useUser() hook to access the user object, which includes the current user's data, like the user's full name. The isLoaded and isSignedIn properties are used to handle the loading state and to check if the user is signed in, respectively.
home.tsximport { useUser } from "@clerk/clerk-react"; export default function Home() { const { isSignedIn, user, isLoaded } = useUser(); if (!isLoaded) { // Handle loading state however you like return null; } if (isSignedIn) { return <div>Hello {user.fullName}!</div>; } return <div>Not signed in</div>; }
Update the current user data with the useUser() hook
The following example demonstrates how to use the useUser() hook to access the user object, which includes the update method for updating the user's data.
home.tsximport { useUser } from "@clerk/clerk-react"; export default function Home() { const { isLoaded, user } = useUser(); if (!isLoaded) { // Handle loading state however you like return null; } if (!user) return null; const updateUser = async () => { await user.update({ firstName: "John", lastName: "Doe", }); }; return ( <> <button onClick={updateUser}>Click me to update your name</button> <p>user.firstName: {user?.firstName}</p> <p>user.lastName: {user?.lastName}</p> </> ); }
Reload user data with the useUser() hook
To retrieve the latest user data after updating the user elsewhere, use the user.reload() method.
home.tsximport { useUser } from "@clerk/clerk-react"; export default function Home() { const { isLoaded, user } = useUser(); if (!isLoaded) { // Handle loading state however you like return null; } if (!user) return null; const updateUser = async () => { // Update data via an API endpoint const updateMetadata = await fetch("/api/updateMetadata"); // Check if the update was successful if (!updateMeta.message === "success") { throw new Error("Error updating"); } // If the update was successful, reload the user data user.reload(); }; return ( <> <button onClick={updateUser}>Click me to update your metadata</button> <p>user role: {user?.publicMetadata.role}</p> </> ); }
