Svelte app built with Windsurf? Let’s review it.
Expert code review for Svelte apps built with Windsurf. We find Windsurf-specific bugs, fix Svelte security issues, and optimize performance. From $19.
Windsurf issues we find in Svelte projects
Problems specific to Windsurf's code generation patterns when building Svelte apps.
Incorrect auth middleware logic
Windsurf generates auth checks that look correct but have logical gaps — missing route protections, incorrect token validation, or bypassable middleware.
SQL injection in raw queries
When Windsurf uses raw SQL instead of an ORM, it sometimes concatenates user input directly into queries rather than using parameterized statements.
Silent data corruption
Type mismatches between frontend and backend go unnoticed. Data gets saved with wrong types or missing fields, causing issues that surface much later.
Circular dependency issues
Complex projects generated by Windsurf sometimes have circular imports that cause runtime errors or undefined values in specific conditions.
Svelte issues we check for
Common Svelte problems that affect production readiness.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: syntax works in components, but manual subscribe() calls in modules need explicit unsubscribe to avoid memory leaks).
Missing form validation
SvelteKit form actions that process submitted data without validating fields, types, or sizes — trusting whatever the user sends.
