Node's webpage
This web page runs inside Node. It is a lightweight web application that can display the information returned by the serial port of the printer in real time, upload and manage files, and perform the most basic control of the printer.
Since the web page storage space of ESP32 is very limited, there are very few js libraries that Node web pages can use.
For the webapi description document implemented by the web page, please refer to this document.
Refer to this document to update the webpage individually. You can just update the webpage without updating the firmware.
