Build apps with Sentry

Sentry crash reporting is wired into every Goodspeed app with null-safe init, breadcrumb helpers, and sensitive-key redaction. Goodspeed generates Sentry as a standard part of every app, so the output is a working codebase from day one, not a scaffold you have to finish yourself.

WHAT GETS GENERATED

Built into every Sentry build

Every app Goodspeed generates with Sentry includes these production-ready patterns, wired together from the first build.

Item	Description	Strength
lib/sentry.ts null-safe initialization	Sentry.init only runs when EXPO_PUBLIC_SENTRY_DSN is set and gasConfig.features.analytics.crashReporting is true. Empty DSN makes all exports no-ops.	Reliability
sanitizeData sensitive-key redaction	sanitizeData redacts any property key matching a regex of 30+ sensitive patterns (password, token, secret, apiKey, etc.) before the event is sent to Sentry.	Security
Breadcrumb helpers for UI, API, auth, navigation	addBreadcrumb(category, message) writes a typed breadcrumb. Callers across lib/posthog.ts, lib/revenuecat.ts, and services/ use it to produce readable event trails.	Debugging
User context enrichment	setSentryUser sets scope.user with the subscription tier, app version, and device model after auth. clearSentryUser clears it on sign-out.	Context
Transaction and span support	captureTransaction wraps expensive operations (image upload, sync replay) in Sentry transactions for performance monitoring.	Performance

REAL GENERATED CODE

A snippet from a Sentry app the studio shipped

This pattern comes directly from the gas-template codebase, the foundation every Goodspeed app is generated on. The studio generates Sentry code like this for every app in the pipeline, not just a hello-world scaffold.

Null-safe init + redaction

// lib/sentry.ts: null-safe Sentry init
const dsn = process.env.EXPO_PUBLIC_SENTRY_DSN ?? '';
const isEnabled = gasConfig.features.analytics.crashReporting && !!dsn;

if (isEnabled) { Sentry.init({ dsn, tracesSampleRate: 0.2 }); }

export function sanitizeData(data: Record<string, unknown>) {
  const SENSITIVE = /password|token|secret|apiKey|authorization/i;
  return Object.fromEntries(
    Object.entries(data).map(([k, v]) =>
      [k, SENSITIVE.test(k) ? '[REDACTED]' : v]
    )
  );
}
