How to pass data of the client component to server component

[stark python]

I know that if you want to use a server component inside a client component, you must wrap it, but how i suppose to pass the data, if i have it in States in the client component?

you cant pass data from client components to server components in conventional means. you have to do it by interacting with the URL itself, for example by adding a search query

[stark python]

and if you want to pass sensitive data?

or for example if i want to do a sign up page, my form is a client component and i have to pass the data throw URL to have it in the server component and save it to the BBDD?

[bleak zenith]

what is BBDD?

[stark python]

database*

[bleak zenith]

well, you can save it in the database

essentially, this is a restriction that you must abide by: server components only know the data present in the http request, which includes the URL and the http headers (including cookies). server components cannot know anything else, such as client-side states

[stark python]

so i can use cookies to do that?

i think is a better way, If I want to pass a lot of information from the client components to the server components

right?

[bleak zenith]

yes cookies is also a valid way to pass data, yes

though if you want to hide it from the user, then cookies won't hide anything. users can always check the cookies content

[stark python]

and what do you recomend to do a sign up and login page?

[bleak zenith]

form => use server actions to handle the submission

[stark python]

oh, so i dont need a client component to handle the page in this case?

[bleak zenith]

you can use a client component or a server component to make the form, no issues with either

[stark python]

ok, ty for the help mate 😄

Not sure if im allowed to ask a question on a already solved question. But I have a page (server comp) and a client component within it that has a form which uses some client validation. When a user submitts that form. Another server component on the same page needs that data.

Client form > Submit data > Perform query to database > Server component needs the returned data

What's the best solution then?
