Svelte app built with Bolt.new? Let’s review it.
Expert code review for Svelte apps built with Bolt.new. We find Bolt.new-specific bugs, fix Svelte security issues, and optimize performance. From $19.
Bolt.new issues we find in Svelte projects
Problems specific to Bolt.new's code generation patterns when building Svelte apps.
Hardcoded credentials in source
Bolt frequently embeds API keys, database URLs, and service credentials directly in source files rather than using environment variables.
No authentication or authorization
Bolt prototypes rarely include auth. Routes and API endpoints are completely unprotected, allowing anyone to access or modify data.
Incomplete error handling
Happy-path-only code that crashes on edge cases. Network failures, empty states, and invalid data cause unhandled exceptions and blank screens.
Missing loading and error states
Async operations show no loading indicators, and failed requests show no error messages — leaving users staring at a blank or frozen screen.
Svelte issues we check for
Common Svelte problems that affect production readiness.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: 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.
