so recently i working on my personal project almost completed frontend and backend both. then i started deployment because both app in different domain.
honestly deployment teach me lot. still initially use auto deploy platforms but still configure diff domain server to connect each other pain..
i already know cors little bit so that not big issue. but browser security things wow too much. cookies sharing issue, same site config, third party cookie problem frontend cant read api cookie. spend many hours just understanding what happening.
also learn cookie security part like secure true use for https only before never think about this but production time understand why important.
learn how same site works, when use lax strict none, how subdomain help make same site better. also cors deeper understanding came when real production.
sometimes frustrating but after fixing one issue that feeling different. like small adrenaline rush after long debugging...
