useSetActiveSession

On success the hook:

1. Optimistically swaps the cached session to the matching entry from useListDeviceSessions.
2. Scrolls the window to the top.
3. Refetches both the session and device-session queries.

Usage

import {
  type MultiSessionAuthClient,
  useAuth,
  useSetActiveSession
} from "@better-auth-ui/react"

const { authClient } = useAuth()
const { mutate: setActive } = useSetActiveSession(
  authClient as MultiSessionAuthClient
)

setActive({ sessionToken: deviceSession.session.token })

useSetActiveSession requires the Better Auth multiSession plugin. Cast authClient to MultiSessionAuthClient so TypeScript picks up the plugin-extended method signature.

Options factory

import { setActiveSessionOptions } from "@better-auth-ui/react"
import { useMutation } from "@tanstack/react-query"

const { mutate } = useMutation(setActiveSessionOptions(authClient))

Note: using the raw factory skips the optimistic session swap — prefer useSetActiveSession unless you only need a stable options object (for example to match on mutationKey inside a global MutationCache observer).
