 # `server$()`
 
-`server$()` allows you to create a function that always execute on the server, making it a great place to access the DB or perform server-only actions.

+`server$()` allows you to define functions that execute exclusively on the server, making it ideal for server-only operations and database access. It functions as an RPC (Remote Procedure Call) mechanism between the client and server, similar to a traditional HTTP endpoint, but strongly typed with TypeScript and easier to maintain.
