How It Works

Three steps to zero downtime

Step 01

Install the SDK

Add a single line of code to your app. Sentinel automatically captures errors, crashes, and performance metrics.

import Sentinel from '@bandhannova/sentinel';
Sentinel.init({ projectId: 'proj_12345' });

Step 02

Errors Stream In

Every unhandled exception, promise rejection, and console error flows into your Sentinel dashboard in real-time.

[INGEST] Project: proj_12345
  Error ID: 847
  Error: TypeError at UserList.tsx:42
  Stack: 3 frames captured
  PII: 2 fields auto-masked ✓

Step 03

AI Explains & Fixes

Our AI instantly analyzes the root cause and writes a production-ready fix suggestion in plain English.

Cerebras AI Diagnostics

Root Cause

The .map() function is being called on users before the API request has resolved, resulting in a TypeError: Cannot read properties of undefined.

Suggested Fix

Add optional chaining to ensure the array exists before mapping over it.

- data.users.map(user => ...)
+ data?.users?.map(user => ...)
