Lovable issues we find in TypeScript projects
Problems specific to Lovable's code generation patterns when building TypeScript apps.
Missing Supabase Row-Level Security
Lovable creates Supabase tables but frequently skips RLS policies, leaving database rows readable and writable by any authenticated — or sometimes unauthenticated — user.
Supabase anon key exposed in client
The Supabase anon key is meant to be public, but without RLS policies it grants unrestricted database access. Lovable apps often expose this key without the matching security layer.
Component state sync issues
Lovable components sometimes fall out of sync with the database state, showing stale data after mutations or navigating between pages.
Broken routing on refresh
Client-side routes generated by Lovable sometimes fail on hard refresh or direct URL access because of missing server-side routing configuration.
TypeScript issues we check for
Common TypeScript problems that affect production readiness.
Excessive use of 'any' type
AI tools use 'any' to bypass type errors instead of defining proper types, removing all the safety benefits TypeScript provides.
Missing strict mode
tsconfig.json without strict mode enables sloppy type checking that allows null errors and implicit any types.
Type assertions instead of type guards
Using 'as' casts to force types instead of runtime checks, causing crashes when data doesn't match the asserted type.
Incorrect generic implementations
Overly complex or incorrect generic types that confuse rather than help, making the code harder to maintain.
