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 warmup data on the server. This function has no effect if called from client-side code.
Notes:
Name representing the data to return to the client-side. Key names are unique within a site. Using the same key name within the same site code overwrites the corresponding data.
Data to return to the client-side.
