Sentry SDK Setup

Detect a project's framework and runtime, then install and configure the correct Sentry SDK with sensible, production-ready defaults: client initialization, DSN via environment variable, error capture, performance/tracing, and source map upload so stack traces are readable.

Consolidation note

Upstream sentry@claude-plugins-official 1.0.0 shipped ~30 separate per-SDK setup skills; this single Lisa-native skill consolidated all of them. As of upstream 1.2.0 Sentry itself consolidated the suite into one sentry-instrument playbook, so the shapes now match — but this skill remains a from-scratch reimplementation against Lisa conventions, not a translation of the upstream skill. Pinned to sentry@[email protected] via synced-from so the parity drift detector tracks it as one unit.

Step 0 — Scope the install

Decide what you are actually doing before touching code; default to the smallest scope (adapted from upstream 1.2.0's scope gate):

• First error — no Sentry yet: install the SDK, initialize it for error capture plus tracing — noting that tracing is opt-in in every Sentry SDK: it only activates when you set tracesSampleRate/tracesSampler (and, in browsers, add the tracing integration, e.g. browserTracingIntegration()), exactly as the Step 3 snippets do — then verify a real captured event and stop. Do not wire up further signals unasked.
• Add a signal — Sentry already installed and the user wants one more signal (logging, profiling, session replay, metrics, cron check-ins, AI/LLM monitoring): skip install/provisioning and configure just that signal per the SDK's docs.
• Full setup — the user asked for "proper" defaults: do first-error, then propose releases + source maps + the signals that fit the app, and add what they accept.

Never over-instrument. Wiring up every signal upfront produces noise, quota burn, and config the team doesn't understand.

Step 1 — Detect framework & runtime

Inspect the project before choosing an SDK. Read package.json (dependencies/scripts), config files, and lockfiles:

• next dependency or next.config.* → Next.js
• @nestjs/core → NestJS
• react-native / expo → React Native / Expo
• react + a bundler (vite/webpack) without Next → React (browser)
• express / fastify / koa and a Node entrypoint → Node server
• vue / @angular/core / svelte → that browser framework
• pyproject.toml / requirements.txt; django/flask/fastapi → Python (and which web framework)
• A plain Node library/CLI → Node

If the runtime is genuinely ambiguous, ask which app to instrument rather than guessing. Respect the project's package manager (bun/npm/pnpm/yarn — match the lockfile) and module system (ESM vs CJS).

Step 2 — Install the package

Use the project's package manager. Examples (swap bun add for your manager):

| Framework | Package | | --- | --- | | React (browser) | @sentry/react | | Next.js | @sentry/nextjs | | Node / Express / Fastify | @sentry/node (+ @sentry/profiling-node for profiling) | | NestJS | @sentry/nestjs (+ @sentry/node) | | React Native / Expo | @sentry/react-native | | Vue | @sentry/vue | | Angular | @sentry/angular | | Svelte / SvelteKit | @sentry/svelte / @sentry/sveltekit | | Python (generic) | sentry-sdk | | Django | sentry-sdk[django] | | Flask | sentry-sdk[flask] | | FastAPI | sentry-sdk[fastapi] |

For Next.js, prefer the official wizard when available — it scaffolds the config files and source-map upload for you:

npx @sentry/wizard@latest -i nextjs

Step 3 — Initialize the client

Initialize as early as possible in the app's lifecycle, before other code runs. Always read the DSN from the environment (see Step 4) — never hard-code it.

React (browser) — src/instrument.ts, imported first in the entrypoint:

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

Sentry.init({
  dsn: import.meta.env.VITE_SENTRY_DSN,
  environment: import.meta.env.MODE,
  integrations: [Sentry.browserTracingIntegration()],
  tracesSampleRate: 0.1, // tune per traffic; 1.0 in dev
});

Node / Express — instrument.ts, required at the very top of the entrypoint (import "./instrument"; must be the first import):

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

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  environment: process.env.NODE_ENV,
  tracesSampleRate: 0.1,
});

Then, after routes are defined: Sentry.setupExpressErrorHandler(app);

NestJS — import ./instrument first in main.ts, then add Sentry's module:

// main.ts — FIRST line
import "./instrument";
// ...
// app.module.ts
import { SentryModule } from "@sentry/nestjs/setup";
@Module({ imports: [SentryModule.forRoot()] })
export class AppModule {}

Next.js — config lives in sentry.client.config.ts, sentry.server.config.ts, sentry.edge.config.ts, and next.config.js is wrapped with withSentryConfig. The wizard (Step 2) writes these; verify the DSN is read from process.env.NEXT_PUBLIC_SENTRY_DSN / process.env.SENTRY_DSN.

React Native / Expo — wrap the root component:

import * as Sentry from "@sentry/react-native";
Sentry.init({
  dsn: process.env.EXPO_PUBLIC_SENTRY_DSN,
  tracesSampleRate: 0.2,
});
export default Sentry.wrap(App);

Python (Django/Flask/FastAPI/generic) — initialize at startup (settings.py, app factory, or main module):

import os
import sentry_sdk

sentry_sdk.init(
    dsn=os.environ["SENTRY_DSN"],
    environment=os.environ.get("ENVIRONMENT", "production"),
    traces_sample_rate=0.1,
    send_default_pii=False,
)

Framework-specific integrations (e.g. DjangoIntegration, FastApiIntegration) are auto-enabled by the matching extra installed in Step 2.

Step 4 — DSN via environment

• Store the DSN in an environment variable, never in committed source.
• Add it to .env.example (with a placeholder) so the requirement is documented, but keep the real value in .env/secrets and confirm .env is gitignored.
• Use the framework's public-env convention for client-side code: NEXT_PUBLIC_SENTRY_DSN (Next.js), VITE_SENTRY_DSN (Vite), EXPO_PUBLIC_SENTRY_DSN (Expo). Server-only code uses SENTRY_DSN.
• For source-map upload (Step 6) the build also needs SENTRY_AUTH_TOKEN, SENTRY_ORG, and SENTRY_PROJECT — these are build/CI secrets, not shipped to the client.

Step 5 — Error + performance monitoring

• Errors: unhandled exceptions/rejections are captured automatically once init runs; add the framework error handler where required (Express: setupExpressErrorHandler; React: an error boundary via Sentry.ErrorBoundary; NestJS: SentryModule). Use Sentry.captureException(err) for caught-but-notable errors.
• Performance/tracing: set a tracesSampleRate (start ~0.1 in production, 1.0 in dev) and enable the framework tracing integration (browser tracing, HTTP/DB auto-instrumentation on the server). Optionally add profiling on Node via @sentry/profiling-node and profilesSampleRate.
• Set environment and (ideally) release so issues are grouped per deploy.

Step 6 — Source maps (readable stack traces)

Minified/transpiled traces are useless without source maps. Configure upload at build time:

• Next.js: handled by withSentryConfig in next.config.js (the wizard sets it up); ensure SENTRY_AUTH_TOKEN/SENTRY_ORG/SENTRY_PROJECT exist in CI.
• Vite/Webpack/Rollup/esbuild: add the Sentry bundler plugin (@sentry/vite-plugin, @sentry/webpack-plugin, etc.) with sourcemaps upload enabled and the same auth env vars.
• Node: build with source maps emitted and upload via sentry-cli sourcemaps upload (or the bundler plugin) in the release step.
• React Native: source maps upload through the Sentry Metro/Gradle/Xcode integration added by the SDK's setup.
• Tie uploads to a release identifier (commit SHA or version) and inject the same release into Sentry.init({ release }) so traces map to the right build.

Step 6a — Name custom telemetry consistently

When adding custom span or log attributes, use the current stable Sentry semantic-convention key for that domain when one exists. Sentry conventions are aligned with OpenTelemetry in many domains, but Sentry's current convention is authoritative for data sent to Sentry. Consult only the relevant domain in the official convention reference, omit deprecated keys, and do not invent a second name for an established attribute. Keep values low-cardinality and never attach secrets, credentials, request bodies, or unnecessary personal data.

Step 7 — Verify

• Build/typecheck to confirm the SDK wiring compiles: bun run build / bun run typecheck (or the project's equivalents).
• Trigger a deliberate test error in a non-production environment and confirm it appears in Sentry with a readable (source-mapped) stack trace.
• Confirm a transaction/trace shows up to validate performance monitoring.
• Remove the test error afterward.

Rules

• Do not port or copy upstream plugin code — reimplement from scratch.
• Never hard-code or commit a DSN or SENTRY_AUTH_TOKEN; route everything through env/secrets and update .env.example.
• Match the project's package manager and module system; do not introduce a new one to install Sentry.
• Initialize Sentry before any other application code runs.
• Tune sample rates for the environment — do not ship tracesSampleRate: 1.0 to high-traffic production by default.
• Prefer current Sentry semantic-convention keys for custom span and log attributes; do not use deprecated keys or invent aliases for established ones.
• Verify with a real captured event and a source-mapped trace before declaring setup complete.
