RyzBook is a simple and open guestbook web application where visitors can leave messages without the need to log in or create an account. Built with React.js, Vite Tailwind CSS, and Firebase, RyzBook allows anyone to share their thoughts, feedback, or greetings permanently.
- Anonymous Messaging – Users can submit messages without signing in.
- Optional Username – If no username is provided, a default name like
anonym-message#<random>is assigned. - Permanent Messages – All messages are stored indefinitely and visible to everyone.
- Message Queue System – A maximum of 100 messages is stored at a time. When a new message is added beyond this limit, the oldest message is automatically removed.
- Rate Limiting – Users can send only one message per hour from the same device.
- Timestamps – Each message displays the sender's name, the message, and the date in the format: Example:
Month/DD/YYYY
- Framework:
- Styling: Tailwind CSS
- Database & Backend: Firebase
- A user enters a username (optional) and a message (required).
- If the username is empty, it defaults to
anonym-message#<random>. - The message is saved in Firebase and displayed instantly.
- The system ensures:
- Users can send only one message per hour from the same device.
- A maximum of 100 messages is stored, using a queue system where older messages are deleted when new ones arrive.
