sentry-sdk-configuration

Initialize Sentry by installing the SDK for your platform, setting your DSN (Data Source Name) from your Sentry project, and calling Sentry.init() early in your application startup. This enables centralized error tracking across JavaScript/TypeScript, Node.js, Python, Go, and other supported runtimes with a single configuration.

Set tracesSampleRate to control what percentage of transactions are monitored, and configure replay settings to capture user sessions for context during errors. Both are configured during SDK initialization alongside your DSN and environment variables for environment-specific tuning.

Yes, Sentry SDKs support framework-specific integrations for JavaScript/TypeScript (Browser, Node.js, Next.js, React), Python (Django), Go, and serverless contexts. Framework-specific integrations are registered during initialization to automatically capture relevant instrumentation.

Configure environment and release parameters during SDK initialization using environment variables or hardcoded values. Environment tags organize errors by deployment stage, while release tagging links errors to specific application versions for tracking when issues were introduced.

Sentry provides platform-specific integrations for each supported runtime and framework, automatically capturing errors, performance metrics, and context. Integrations are registered during initialization and vary by platform—JavaScript frameworks get replay and session replay, while serverless contexts get cold-start and invocation tracking.

Initialize Sentry before other code runs to capture startup errors and ensure all downstream modules report to Sentry. Early initialization is a best practice that prevents errors during application bootstrap from going untracked.
