Client-Side
Code or processing that runs in the user's browser application or device rather than on a remote server.
Plain English
Work performed by the app on the user's device.
In context
Client-side logic supports interaction rendering caching and validation but executes in an environment the service cannot fully trust or control.
Example
“The form performs client-side validation before sending the request.”
