CHATROOM

This is a simple chatroom application built with Node.js and Express that allows users to register, log in, and send, edit, and delete messages. The application uses Sequelize for database interactions and cookies to manage user sessions.

• Registration: New users can register by entering their email, first name, last name, and setting a password.
• Message System: Users can send, edit, and delete messages in the chatroom.
• Search: Users can search messages by keywords.
• Session Management: Users are logged in with a cookie that expires after 30 seconds for security reasons.

Requirements

• Node.js: Version 14 or higher
