Sentry SDK setup for SvelteKit involves initializing error monitoring, tracing, and session replay across client and server boundaries, wiring instrumentation hooks, and optionally configuring Vite source maps for complete stack observability.

Yes, Sentry session replay and logging can be configured across both client and server in Svelte. This setup wires front-end and back-end initialization together, ensuring consistent observability across the entire stack.

This Sentry setup supports both modern (SvelteKit ≥2.31.0) and legacy setups. It provides guidance for choosing the right integration path, ensuring compatibility whether you are starting a new project or migrating an older codebase.

The best way to add end-to-end observability during a Svelte migration is to apply an opinionated Sentry setup that consolidates client and server initialization, wires instrumentation hooks, and configures Vite source maps, enabling faster issue detection.

To configure Vite source maps for Sentry in a SvelteKit project, you apply the optional source map configuration provided during SDK setup. This ensures errors are accurately mapped to original source code for easier debugging across client and server.
