-Server-ScriptLibraries contain code happening at the server before sending the data to the client. Every [[protogrid:proto|Proto]] can have a server side library attached. Whenever something is done with a [[protogrid:card|Card]] of this Proto on the server, the Server takes the assigned library into account. The server side libraries contain mainly the following functions: on_render, on_save, get_shortname, get_title. +Server ScriptLibraries contain code happening at the server before sending the data to the client.

 on_render gets called when opening a new Card. This function can be used for example to [[protogrid:hide_field| hide fields]] of the Card. Inside the on_render function, one has access to the card which is opening as well as to a predicate called "before_first_save" telling you whether the Card was already saved before or not (if not, it is a newly created Card).  on_render gets called when opening a new Card.

-Please note that all your code should reside within a enclosing function in order to limit its scope and avoid naming conflicts. Protogrid supports you in this by automatically providing such an enclosing function in the default Client ScriptLibrary and replacing the identifier of this enclosing function with the name of the Client ScriptLibrary before loading it into the browser. However, you are free to set your own static identifier for this function.+Please note that all your code should reside within a enclosing function in order to limit its scope and avoid naming conflicts.
