Performance for your Bolt.new-built Svelte app
Expert performance for Svelte apps built with Bolt.new. We audit Bolt.new-generated Svelte code for performance issues. From $19.
Bolt.new issues we find in Svelte projects
Problems specific to Bolt.new's code generation patterns when building Svelte apps.
Hardcoded credentials in source
Bolt frequently embeds API keys, database URLs, and service credentials directly in source files rather than using environment variables.
No authentication or authorization
Bolt prototypes rarely include auth. Routes and API endpoints are completely unprotected, allowing anyone to access or modify data.
Incomplete error handling
Happy-path-only code that crashes on edge cases. Network failures, empty states, and invalid data cause unhandled exceptions and blank screens.
Svelte performance issues we check for
Performance-specific Svelte problems that need attention before production.
Store subscriptions causing memory leaks
Manual store subscriptions ($: syntax works in components, but manual subscribe() calls in modules need explicit unsubscribe to avoid memory leaks).
Incorrect use of derived state
AI-generated Svelte code uses reactive statements ($:) for complex derived data without memoization, recalculating expensive operations on every state change.
