​
Overview

reset() clears the current user identity set by identify(). Call it when a user logs out to prevent their events from being mixed with the next user’s events on the same device.

​
Signature

reset(): void

​
Parameters

None. reset() takes no arguments.

​
Example

import { reset } from 'analytiq'

reset()

​
When to call it

Always call reset() when a user logs out: 
import { reset } from 'analytiq'

async function handleLogout() {
  await api.post('/auth/logout')  // your own logout API call
  reset()                          // clear Analytiq identity
  navigate('/login')               // redirect to login page
}

​
What it clears

ClearedDescription
userId (memory)Removes the user set by identify(). Future events are anonymous.
userId (localStorage)Clears the persisted userId so the user is not re-identified on next page load.
Offline event queueClears any events saved to localStorage while the user was offline.
Event queue (memory)Clears any events queued before init() was called
Dedup cacheClears the 300ms deduplication memory

​
Why this matters

If you don’t call reset() on logout:
  • User A logs out
  • User B logs in on the same browser
  • User B’s events are attributed to User A’s identity on the dashboard
Calling reset() prevents this by wiping User A’s identity from both memory and localStorage.

Complete login/logout flow

import { identify, track, reset } from 'analytiq'

// On login:
async function onLoginSuccess(user) {
  identify(user.id)                            // link events to this user
  track('login', { method: 'email' })          // track the login event
  navigate('/dashboard')
}

// On logout:
async function onLogout() {
  track('logout')                              // track the logout event
  reset()                                      // clear identity
  navigate('/login')
}
