User identification

Overview

User identification lets you see which users are affected by

each error, helping you prioritize fixes based on real impact.

Privacy-first design

Trovi never stores PII. All user IDs are one-way hashed

before storage. You can safely pass any identifier — database

ID, session token, username — and Trovi will hash it to an

anonymous string.

Setup

Identify on login

import { identifyUser } from '@trovi/sdk/browser'

identifyUser(session.user.id)

Set at init time

init({
  apiKey:       'your-key',
  dashboardUrl: 'https://...',
  userId:       currentUser.id,
})

Clear on logout

import { clearUser } from '@trovi/sdk/browser'
clearUser()

Anonymous users

If you don't call identifyUser(), Trovi automatically

assigns a random anonymous ID stored in localStorage.

Anonymous IDs start with anon_. Identified user IDs

start with uid_.

What you see in the dashboard

• Impact score on each ticket
• Affected users and counts per issue
• User explorer with aggregate error history
• User detail views with ticket and event patterns

Node.js

import { captureEvent } from '@trovi/sdk/node'

captureEvent({
  type:     'js_error',
  severity: 'error',
  message:  err.message,
  metadata: {
    userId: req.user?.id,
    path: '/api/orders',
  }
})
