Building a booking system with Angular? Let us review it.
Expert code review for booking systems 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.
Booking System challenges to solve
Key booking system concerns that AI-generated code often misses.
Double-booking prevention
Two customers booking the same time slot simultaneously is the most critical failure mode. AI-generated booking logic often has race conditions — checking availability and creating the booking aren't atomic, so two requests can both see the slot as available and both succeed.
Timezone handling
If your provider is in New York and your customer is in Los Angeles, a '2 PM appointment' means different things. AI tools store times in the server's timezone or the developer's local timezone, causing bookings to appear at wrong times for users in other timezones.
Calendar integration and availability
Providers have existing calendars (Google Calendar, Outlook) that affect their availability. Without two-way calendar sync, providers get double-booked with their personal events, or manual availability management becomes a full-time job.
Payment and cancellation policies
Bookings often require deposits or full prepayment. Cancellation policies (full refund within 24 hours, 50% after that, no refund day-of) need precise time-based logic. AI tools implement basic checkout but not the nuanced refund rules that booking businesses need.
What we check
Key areas we review for Angular booking system projects.
Double-booking prevention — atomic availability checks and booking creation
Timezone handling — correct display and storage across all timezones
Payment integration — deposits, refunds, cancellation policy enforcement
Notification pipeline — confirmations, reminders, cancellation alerts

Frequently asked questions
Can you review a booking system built with Angular?
Yes. We regularly audit Angular booking system 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 booking systems?
Common issues include memory leaks from unsubscribed observables and bypassed domsanitizer on the Angular side, combined with booking system-specific concerns like double-booking prevention and timezone handling. We check for all of these and more.
How do I make my Angular booking system production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Angular booking system projects, the typical path is: fix security gaps, address booking system-specific requirements, optimize Angular performance, then configure deployment. We provide a fixed quote after the audit.
