React app built with Firebase Studio? Let’s review it.
Expert code review for React apps built with Firebase Studio. We find Firebase Studio-specific bugs, fix React security issues, and optimize performance. From $19.
Firebase Studio issues we find in React projects
Problems specific to Firebase Studio's code generation patterns when building React apps.
Firestore security rules too permissive by default
Firebase Studio frequently generates Firestore rules that allow authenticated users to read and write any document in the database, without scoping access to documents owned by that user.
Client-side security logic that can be bypassed
Access control checks are placed in frontend React components rather than Firestore rules or Cloud Functions, allowing users to bypass restrictions by making direct Firestore SDK calls.
Cloud Function cold start latency degrading UX
Infrequently-called Cloud Functions take 2-5 seconds to cold start, causing noticeable delays on first API calls and making the app feel slow during low-traffic periods.
Unhandled Firestore transaction conflicts
Concurrent writes to the same documents cause transaction conflicts that are not properly caught or retried, resulting in lost updates and silent data inconsistencies.
React issues we check for
Common React problems that affect production readiness.
XSS via dangerouslySetInnerHTML
AI tools use dangerouslySetInnerHTML to render dynamic content without sanitization, allowing script injection.
Exposed environment variables
Sensitive keys placed in NEXT_PUBLIC_ or REACT_APP_ prefixed variables, making them visible in the browser bundle.
Unnecessary re-renders
Missing React.memo, useMemo, and useCallback cause components to re-render on every parent update, degrading performance.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.

Frequently asked questions
Can you review React code generated by Firebase Studio?
Yes. We regularly audit React projects built with Firebase Studio and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What React issues does Firebase Studio typically create?
Common issues in Firebase Studio-generated React code include: firestore security rules too permissive by default, client-side security logic that can be bypassed, cloud function cold start latency degrading ux. Combined with React-specific concerns like xss via dangerouslysetinnerhtml and exposed environment variables.
How do I make my Firebase Studio React project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Firebase Studio-built React projects, the typical path is: fix security gaps, address React-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Firebase Studio-generated React code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
