  "account": "Adding a booking page to a Next.js app with a REST API involves several components. The service catalog lists what can be booked, such as a 60-minute session or a color treatment, along with its duration, price, and the staff who can provide it. Real-time availability determines which slots are open for a specific service and date range, taking into account existing bookings, staff hours, buffer time, and multi-staff conflicts. A cart and checkout feature allows customers to reserve a slot while entering details and making a payment, ensuring race-safe handling of limited resources. Post-booking management includes confirming bookings, sending reminders, and enabling customers to reschedule or cancel without additional email communication. To implement this, you can use a booking API like Opencals, which simplifies the backend logic while keeping full control of the Next.js frontend. The frontend consists of a few forms and a calendar grid, while the backend handles real-time availability across staff, services, and existing bookings, as well as payments. By calling a booking API, you can focus on the frontend while offloading the complex backend tasks.",

Adding a booking page to a Next.js app looks like a weekend project until you start it. The UI is the easy part. The hard part is everything the calendar needs to know before it can show a single open slot: which staff are working, how long the service takes, what's already booked, how much buffer…",
