Building a chrome extension with NestJS? Let us review it.
Expert code review for chrome extensions built with NestJS. We fix NestJS-specific security gaps, optimize performance, and handle deployment. From $19.
Common NestJS issues we find
Real problems from NestJS codebases we've reviewed.
Missing authentication guards
Controllers and routes without @UseGuards decorators, leaving endpoints publicly accessible without any auth checks.
Incorrect dependency injection scope
Services registered with wrong scope (default singleton vs request-scoped) causing shared state between requests and data leakage between users.
Unvalidated DTOs
Data Transfer Objects without class-validator decorators or missing the global ValidationPipe, accepting any shape of input data.
Circular dependency issues
Modules importing each other in cycles, causing runtime errors or undefined injections that only surface in production.
Chrome Extension challenges to solve
Key chrome extension concerns that AI-generated code often misses.
Manifest V3 compliance
Chrome is migrating to Manifest V3, which changes how extensions work — service workers instead of background pages, restricted remote code execution, and new permission models. AI tools sometimes generate Manifest V2 code that won't be accepted.
Permission minimization
Chrome Web Store reviews extensions for excessive permissions. Request only the permissions you actually need. AI tools often request broad permissions ('tabs', 'storage', 'activeTab') when narrower permissions would suffice.
Content Security Policy
Extensions must comply with strict CSP rules. No inline scripts, no eval(), no remote code loading. AI-generated code sometimes violates these rules, causing the extension to fail silently.
Data privacy
Extensions that access browsing data must have a privacy policy, explain what data is collected, and handle it securely. Chrome Web Store requires this disclosure for approval.
What we check
Key areas we review for NestJS chrome extension projects.
Manifest V3 compliance — service workers, permissions, CSP
Permission minimization — only requesting what's needed
Content security — no eval(), no inline scripts, no remote code
Data handling — privacy policy, secure storage, no unnecessary collection
