Live Demo: https://collaborative-whiteboard.vercel.app/

This is a collaborative whiteboard that allows real-time communication through sockets. It was built using Next.js, Spring Boot and MongoDB. Users can share a room and draw on canvas which will be updated on every participant's screen.

When the app is launched, the user must create a room or join an existent one. If the user chooses to create a room, a username and a room name is required. Else, to join a room a username and the room ID are required.

• Once the room is created, it will be stored in MongoDB Database.
• Other users can join this room if they know its ID
• Every time a user joins or leaves a room, the message will be broadcasted to all users in that specific room through sockets.
• Each user in a room can draw on canvas, change the width of pencil, erase drawings, save the canvas or import other.
• Each drawing is stored in Database. Drawings are broadcasted as json object which holds coordinates of drawing, color, lineWidth, and the ID of the user who draw it.
