docs-es | : black_joker : Un generador mágico

Okay, two things here. firstly, it isn't a good idea to update your DB on every keystroke. Think about it. You are making a post request to your server more than once in a second with a payload and touching DB. Not ideal. So either you keep this data cached and save it once it crosses a threshold (say after one paragraph or X number of characters) or,

secondly, you can do some tweaks at the front-end side also here. Make sure you catch only valid or wanted keystrokes. Use reactive programming. Check for Rxjs and filter out invalid characters or catch only at a certain interval. Hope this will help.
