set( )

Sets data in server-side code for use in client-side code.

A performance best practice is to set warmup data for time-consuming operations, such as querying collections or working with the results of network requests from external sites. You can write code that sets the data from these operations as warmup data on the server. The client-side code can then get that data without performing the operations again.

You can only set warmupData on the server. This function has no effect if called from client-side code.
