Lisa Parity Sentry Sdk Setup

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

The upstream sentry@claude-plugins-official plugin ships ~30 separate per-SDK setup skills (one per framework/runtime). This single Lisa-native skill consolidates all of them: instead of one thin skill per SDK, it detects the framework and applies the matching case below. The behavior is reimplemented from scratch against Lisa conventions — it is not a translation of the upstream skills. Pinned to sentry@claude-plugins-official@1.0.0 via synced-from so the parity drift detector tracks it as one unit.

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):

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 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.
• Verify with a real captured event and a source-mapped trace before declaring setup complete.
