A process performed on a server includes configuring the server to enable script for a Web service to be defined dynamically, where the Web service includes an application program interface (API) for enabling access by, and interaction with, a computer program executing on a device other than the server. The process also includes compiling the script to produce machine-executable code for the Web service, receiving a call from the computer program to the Web service, executing the machine-executable code in response to the call to produce an output, and sending the output to the device.
