Everyone, could someone give me a help.
I have a question about how the data of an online text editor in the google docs style is saved, it happens automatically, but the question for me is, how? via API? something like Socket.io? I'm having a hard time understanding how this happens, how the data is sent to the server, can anyone help me?
I wonder, a person goes there and writes three pages, but after continuing to write after the third page, how do I save only the modified content? or will I always have to save everything?
