How can i return a custom header from a loader?

In remix, we have data util that allows to return data with custom headers. Do we have the same thing in tanstack start?

yes a route's head property is a function which receives loader data as a parameter so your loader returns data, and you can access it in head

I mean the headers like set-cookie, max-age, etc.

a loader runs on server initially and then on the client so no you cant set a header for a loader what do you want to do here?

In the loader, i call an API and it returns data with the set-cookie header. I want to set that cookie in the user's browser. If the loaders run on the client, it should automatically set the cookie because it fetches on the client. But on the server, it doesnt work that way. In remix, they have the function "data" so they can return stuff like this in the loader

data(data, 
headers: {
    Cache-control: ....
}
)

data(data, 
headers: {
    Cache-control: ....
}
)

put the logic into a server function and then call that server function from the loader. within the server function you can call setResponseHeader
