Composable events for dynamic user interface composition

A system, comprising:

• a data storage device;
• and
• a processor coupled to the data storage device and configured to, prior to execution of an application:
• obtain, at a software development tool, a template that provides an interface for receiving structured user input;
• receive structured user input defining a customized interface event, the structured user input defining a data value to be associated with the custom user interface event, an event scope, wherein the custom user interface event is published only within the defined event scope and is consumable by page elements other than a user interface element that publishes the custom user interface event only within the defined event scope, and one or more trigger events that trigger the custom user interface event to be published;
• receive a first definition of the user interface element configured to publish the custom user interface event;
• receive a second definition of an additional application user interface element, the additional application user interface element configured to subscribe to the custom user interface event;
• and
• generate based at least in part on the structured user input, application user interface code, wherein during execution of the application, in response to at least one of the defined trigger events, the application user interface code publishes to a client an instance of the custom user interface event.

A computer program product to provide a user interface, the computer program product being embodied in a non-transitory computer-readable storage medium and comprising computer instructions for:

• prior to execution of an application,
• obtain, at a software development tool, a template that provides an interface for receiving structured user input;
• receive structured user input defining a customized interface event, the structured user input defining a data value to be associated with the custom user interface event, an event scope, wherein the custom user interface event is published only within the defined event scope and is consumable by page elements other than a user interface element that publishes the custom user interface event only within the defined event scope, and one or more trigger events that trigger the custom user interface event to be published;
• receive a first definition of the user interface element configured to publish the custom user interface event;
• receive a second definition of an additional application user interface element, the additional application user interface element configured to subscribe to the custom user interface event;
• and
• generate based at least in part on the structured user input, application user interface code, wherein during execution of the application, in response to at least one of the defined trigger events, the application user interface code publishes to a client an instance of the custom user interface event.
