Performance for your Windsurf-built Svelte app
Expert performance for Svelte apps built with Windsurf. We audit Windsurf-generated Svelte code for performance issues. From $19.
Windsurf issues we find in Svelte projects
Problems specific to Windsurf's code generation patterns when building Svelte apps.
Incorrect auth middleware logic
Windsurf generates auth checks that look correct but have logical gaps — missing route protections, incorrect token validation, or bypassable middleware.
SQL injection in raw queries
When Windsurf uses raw SQL instead of an ORM, it sometimes concatenates user input directly into queries rather than using parameterized statements.
Silent data corruption
Type mismatches between frontend and backend go unnoticed. Data gets saved with wrong types or missing fields, causing issues that surface much later.
Svelte performance issues we check for
Performance-specific Svelte problems that need attention before production.
Store subscriptions causing memory leaks
Manual store subscriptions ($: 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.
