@Brown bear dont think for now that we can call server action from outside

Why do you want to call server actions from outside ? Just call the API? My understanding is Server Actions are just syntactic sugar for API calls in your RSCs

I was under the impression that server action replace API endpoints in nextjs

I'm no expert, but I think the idea is instead of making traditional API endpoints, you create a server action which allows you to bypass a) making an API endpoint, b) calling it... For the times when the API endpoint is made for just that reason (and not to be called from outside like a traditional endpoint), just a quick way to add form submissions and similar in RSC

Definitely could be wrong, I'm not 100% on my understanding

So instead of making an API endpoint for just 1 form, and then calling it from just that 1 form. (you now have the 2 sides of the API interaction), you just make a simple server action, and it's quick code, lightweight, and feels like frontend stuff

https://nextjs.org/docs/app/building-your-application/routing/route-handlers

build APIs with this

the big picture vision is that route handlers are only necessary if you need to expose an API endpoint to external services and for everything in your own application to use Server Actions

but as of now, it's pretty standard to use route handlers to create API endpoints that your client components use (especially considering that server actions are experimental and not feature complete)

Jarrah, do you know if server actions are providing responses ?
Success, Errors, input validation feedback ?

i haven't tried

I.e Login component, being able to validate, or respond to successful logins

ok, when i tried a month ago, it was not able, which made it difficult to use, so switched to client components for that
