Building a api / backend service with Angular? Let us review it.
Expert code review for api / backend services built with Angular. We fix Angular-specific security gaps, optimize performance, and handle deployment. From $19.
Common Angular issues we find
Real problems from Angular codebases we've reviewed.
Memory leaks from unsubscribed Observables
Subscribing to Observables in components without unsubscribing on destroy, causing memory leaks and ghost subscriptions that fire after navigation.
Bypassed DomSanitizer
Using bypassSecurityTrustHtml() to render user-supplied content without proper sanitization, re-introducing XSS vulnerabilities that Angular's built-in sanitizer prevents.
Change detection performance issues
Default change detection strategy on components with expensive templates, causing Angular to re-evaluate bindings on every event cycle.
Improper lazy loading
All modules eagerly loaded in the root module instead of lazy-loaded per route, resulting in large initial bundle sizes and slow startup.
API / Backend Service challenges to solve
Key api / backend service concerns that AI-generated code often misses.
Authentication and API keys
Every endpoint needs to verify the caller's identity. AI tools create endpoints without auth, or with auth that's easy to bypass. You need token-based auth, API key management, and proper session handling.
Input validation
Every parameter, request body, and header value must be validated before use. AI-generated APIs trust client data, which leads to injection attacks, data corruption, and crashes from unexpected input.
Rate limiting and abuse prevention
Without rate limits, anyone can hammer your API — brute-forcing passwords, scraping data, or running up your infrastructure costs. Rate limiting must be per-user and per-endpoint.
Error handling and status codes
APIs should return appropriate HTTP status codes (400 for bad input, 401 for unauthorized, 404 for not found, 500 for server errors) with helpful error messages. AI tools often return 200 for everything or expose internal error details.
What we check
Key areas we review for Angular api / backend service projects.
Authentication on every endpoint — no unprotected routes
Input validation — every parameter validated with schema
Rate limiting — per-user, per-endpoint limits configured
Error responses — correct status codes, no internal detail leaks

Frequently asked questions
Can you review a api / backend service built with Angular?
Yes. We regularly audit Angular api / backend service projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in Angular api / backend services?
Common issues include memory leaks from unsubscribed observables and bypassed domsanitizer on the Angular side, combined with api / backend service-specific concerns like authentication and api keys and input validation. We check for all of these and more.
How do I make my Angular api / backend service production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Angular api / backend service projects, the typical path is: fix security gaps, address api / backend service-specific requirements, optimize Angular performance, then configure deployment. We provide a fixed quote after the audit.
