Building a real-time app with Angular? Let us review it.
Expert code review for real-time apps 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.
Real-time App challenges to solve
Key real-time app concerns that AI-generated code often misses.
Connection management and reconnection
WebSocket connections drop constantly — network switches, phone sleep, server deploys. AI tools open a connection but don't handle disconnection, reconnection, or missed messages during downtime. Users see stale data or lose messages without knowing it.
Message ordering and delivery guarantees
Messages must arrive in order and must not be lost. Network issues can deliver messages out of sequence or duplicate them. AI-generated real-time code has no message ordering, no deduplication, and no delivery confirmation — which means lost messages and confused users.
Conflict resolution in collaborative editing
When two users edit the same content simultaneously, whose changes win? AI tools implement 'last write wins,' which silently discards one user's work. Production collaboration needs operational transforms or CRDTs to merge concurrent edits correctly.
Scaling concurrent connections
Each WebSocket connection holds server resources. A single server can handle hundreds of connections, but thousands require load balancing with sticky sessions, a pub/sub layer (like Redis), and horizontal scaling. AI tools don't implement any of this.
What we check
Key areas we review for Angular real-time app projects.
Connection lifecycle — reconnection logic, heartbeat, graceful degradation
Message delivery — ordering guarantees, deduplication, acknowledgments
Authentication — WebSocket connections verified, channel-level authorization
Scaling — connection pooling, pub/sub architecture, horizontal scaling readiness

Frequently asked questions
Can you review a real-time app built with Angular?
Yes. We regularly audit Angular real-time app 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 real-time apps?
Common issues include memory leaks from unsubscribed observables and bypassed domsanitizer on the Angular side, combined with real-time app-specific concerns like connection management and reconnection and message ordering and delivery guarantees. We check for all of these and more.
How do I make my Angular real-time app production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Angular real-time app projects, the typical path is: fix security gaps, address real-time app-specific requirements, optimize Angular performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a Angular real-time app?
Our code audit delivers a full report within 24 hours. For Angular real-time app projects, we check security, architecture, performance, and deployment readiness across all Angular-specific patterns. Fixes are scoped separately with a fixed quote.
