Add Error Tracking (Sentry)

Use this skill when the user asks to add error tracking, crash reporting, exception monitoring, or performance tracing.

Steps

Detect the framework — check
```
package.json
```
, config files, and directory structure to determine the stack (Next.js, React, Node.js, Python/Django/Flask, etc.).

Install the SDK

Next.js:
```
npx @sentry/wizard@latest -i nextjs
```
React (Vite):
```
npm install @sentry/react
```
Node.js:
```
npm install @sentry/node
```
Python:
```
pip install sentry-sdk
```

Initialize Sentry

For Next.js, the wizard creates
```
sentry.client.config.ts
```
,
```
sentry.server.config.ts
```
, and
```
sentry.edge.config.ts
```
. Verify they exist and contain the DSN.

For React (Vite), init in

main.tsx

:

tsx

import * as Sentry from "@sentry/react";

Sentry.init({
  dsn: import.meta.env.VITE_SENTRY_DSN,
  integrations: [Sentry.browserTracingIntegration()],
  tracesSampleRate: 1.0,
});

For Node.js, init at the very top of the entry file before any other imports.

Add environment variables

NEXT_PUBLIC_SENTRY_DSN=https://...@sentry.io/...
SENTRY_AUTH_TOKEN=sntrys_...
SENTRY_ORG=your-org
SENTRY_PROJECT=your-project

Add error boundary — wrap the app (or critical subtrees) with
```
Sentry.ErrorBoundary
```
and a fallback UI.
Source maps — for production builds, configure the Sentry webpack/vite plugin to upload source maps. For Next.js, this is handled by
```
withSentryConfig
```
in
```
next.config.js
```
.
Test the integration — add a temporary button that throws an error to verify events appear in the Sentry dashboard.

Notes

Set
```
tracesSampleRate
```
to a lower value (e.g.
```
0.1
```
) in production to control costs.
Add
```
sentry.properties
```
and
```
.sentryclirc
```
to
```
.gitignore
```
.
Never commit
```
SENTRY_AUTH_TOKEN
```
.
