PixelCanvas.io bot

Setup: (assuming Firefox, but any web browser would work)

• Install Node.js and ImageMagick
• Clone the repository using git clone https://github.com/mekb-turtle/pixel-canvas-bot.git or download .zip/.tar.gz of the repository and extract it
• Run npm i in the directory to install the dependencies
• Create a new file called .env in the directory of the repository
• Go to PixelCanvas.io
• Open network tab in developer tools
• Click a pixel on the canvas to draw it
• Open one of the network requests that says pixel (not online or X.Y.bmp)
• Open the Request tab
• Add FIREBASE= followed by the value of appCheckToken from the request body to the .env file
• Add FINGERPRINT= followed by the value of fingerprint from the request body to the .env file
• Use node . --help for help

The X-Firebase-AppCheck header has recently been moved to appCheckToken in the request body. Tokens now expire much quicker, and a CAPTCHA has been added.

If you get 401 Unauthorized, your firebase token or fingerprint is invalid. Delete the .env file and redo the "Setup" starting from "Create a new file called .env".

If you get 412 Precondition Failed, you have placed a pixel too recently, your cooldown hasn't expired yet. The program should wait in intervals of 10 seconds until this is over.

I've only tested this on Artix Linux and Windows 10.

The countdown/progress indicator won't show correctly on some Windows versions.
