color-picker | Simple color picker for GNOME Shell | Calendar library

I would really appreciate If someone could figure out what is wrong with my functions. I'm working on this simple paint program and I have Undo and Clear buttons. Undo is supposed to clear the last drawn line (the function deletes the last element of the array since the array consist of all the drawn lines on the canvas) and Clear just takes the canvas back to It's formal state (makes the board completely white). But every time I put any of those functions in the code my canvas just deletes Itself and I can't seem to figure out what's wrong. The function names are clear_canvas and undo_last. Any tips or solutions on how to fix or make another working example?

I'm working on this simple drawing program using HTML CSS and JSC only. I have a problem where I can't fix where my div elements with the class color-field, they won't go horizontal (in line block one next to another). Instead they for some reason go diagonal and all the elements after them go like that. I want to make them go under the canvas one next to another but I can't seem to make it work. I tried all the methods I found online and nothing works. I'm not sure what is the problem really?

Haven't made this feature before where you can change the color of button's hover.

I have already made a feature to change the radius with a slider, background color and font color using color-picker. However, I noticed the hover (for background AND font) could be better.

Here is the code:

I'm trying to make a collaborative whiteboard, where multiple clients connect to the server and each can see what everyone is drawing on the board. The way that it is run is first you have to type in the terminal node server.js to execute the server.js file, which runs on localhost:5000. After that you open a new terminal and then type npm start and it opens the React app on localhost:3000. Now the problem is that my other device tells me GET http://localhost:5000/user net:ERR_CONNECTION_REFUSED when I click on inspect. This is the link to show me JSON data of pictures from the MySQL database. So I cannot see pictures from the database on the whiteboard on different devices. Only on my own device. But the weird thing is that I can only see the JSON data when I explicitly type the IP address and then the port and /user in a different tab. But on the whiteboard itself, it tells me this error and shows me no pictures from the database.

This is the server.js code:

im trying to show images from the database and loop through them with a map. Here is the code:
