Hey all, ive been a frontend dev for a while so ive never really had to do much backend stuff. My question is, I'm helping a friend with a portfolio but hes not a coder, so I can code the website but how would he be able to edit it? Is there a way to add a backend portal where he could login and change texts in a form with inputs that when submitted make a POST request to update the web? Is that possible without a server? For context the website is hosted on firebase (just the free hosting, no server) and im using React and next.js
