Common Bugs in Create.xyz-Generated Code

Create.xyz optimizes for rapid visible output and may not fully implement the authentication and authorization logic needed to protect multi-user applications. Error handling between frontend and backend is often incomplete

Create.xyz apps frequently have authentication gaps — pages that should require login are accessible without it, and user-specific data isn't properly scoped. MongoDB queries often retrieve all documents rather than filtering to the current user's data. Form submissions may succeed on the frontend while silently failing on the backend without user feedback

Start by running your app through its complete user flow — sign up, use every feature, try edge cases like empty inputs and invalid data. Most Create.xyz bugs surface when you go off the happy path. Use your browser's developer tools to watch for console errors, failed network requests, and unhandled promise rejections. TypeScript's strict mode will catch many issues at compile time if it's not already enabled.

For async errors, wrap every server-side operation in try/catch blocks and return meaningful error messages. For state bugs, consider whether the state belongs in the URL, in a server component, or in client state — Create.xyz often defaults to client state when server state would be more appropriate. For data fetching issues, implement proper loading and error states for every data-dependent component.

The best way to prevent Create.xyz bugs from reaching production: enable TypeScript strict mode, add ESLint rules for common mistakes (no-floating-promises, exhaustive-deps), and write tests for critical user flows. Even basic smoke tests catch the majority of issues.
