Node.js app built with Fine.dev? Let’s review it.
Expert code review for Node.js apps built with Fine.dev. We find Fine.dev-specific bugs, fix Node.js security issues, and optimize performance. From $19.
Fine.dev issues we find in Node.js projects
Problems specific to Fine.dev's code generation patterns when building Node.js apps.
Spec interpretation may differ significantly from intent
Fine.dev builds exactly what the specification says, not what you meant. Ambiguous specs lead to technically correct implementations that miss the actual product requirement.
Cross-file changes may miss security implications
When Fine.dev generates features spanning multiple files, security-sensitive changes — new endpoints, auth checks, data access patterns — are spread across the PR without a consolidated security review surface.
Generated tests may not cover real-world edge cases
Fine.dev writes tests for the happy path and obvious failure cases from the spec. Edge cases not explicitly mentioned — concurrent requests, null inputs, rate limits — are frequently untested.
Cross-file changes introduce inconsistencies
Large implementations touching many files accumulate subtle inconsistencies — type assumptions that don't hold across modules, different error handling patterns in different files.
Node.js issues we check for
Common Node.js problems that affect production readiness.
No input validation
Request bodies and query parameters accepted without validation, enabling injection attacks and unexpected data types.
Missing rate limiting
No rate limiting on auth endpoints, API routes, or resource-intensive operations, enabling brute-force and DoS attacks.
Unhandled async errors
Unhandled promise rejections crash the Node.js process in production, taking the entire server down.
Memory leaks
Event listeners not cleaned up, growing arrays/maps, and unclosed connections that gradually consume all available memory.

Frequently asked questions
Can you review Node.js code generated by Fine.dev?
Yes. We regularly audit Node.js projects built with Fine.dev and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Node.js issues does Fine.dev typically create?
Common issues in Fine.dev-generated Node.js code include: spec interpretation may differ significantly from intent, cross-file changes may miss security implications, generated tests may not cover real-world edge cases. Combined with Node.js-specific concerns like no input validation and missing rate limiting.
How do I make my Fine.dev Node.js project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Fine.dev-built Node.js projects, the typical path is: fix security gaps, address Node.js-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Fine.dev-generated Node.js 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.
