I’m webGL engine developer (ThreeJS) in small company. We have some events in few weeks and my boss just told me that i have to make registration form as soon as possible, also one page should show names, lastnames and company of all registered members. Problem is that i’m very bad in databases and i have really small amount of time to re-learn it. How can i store registration data on Server without Database? I looked up on web and most instructions are unclear(because i’ve not worked on database before) and others are using localstorage (as far as i know its used for cacheing data)
What you're looking for is a flat file database system, try taffyDB it basically use Json to store its data or Papa parse that uses CSV files, you can easily edit with excel for example.
If you're really good with javascript you can consider using a real database after all,mongodb is a bit advance but still not as complicated as mysql or even sqlite.
