TypeScript app built with Firebase Studio? Let’s review it.
Expert code review for TypeScript apps built with Firebase Studio. We find Firebase Studio-specific bugs, fix TypeScript security issues, and optimize performance. From $19.
Firebase Studio issues we find in TypeScript projects
Problems specific to Firebase Studio's code generation patterns when building TypeScript 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.
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.

Can you review TypeScript code generated by Firebase Studio?
Yes. We regularly audit TypeScript projects built with Firebase Studio and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What TypeScript issues does Firebase Studio typically create?
Common issues in Firebase Studio-generated TypeScript 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 TypeScript-specific concerns like excessive use of 'any' type and missing strict mode.
How do I make my Firebase Studio TypeScript project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Firebase Studio-built TypeScript projects, the typical path is: fix security gaps, address TypeScript-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
