Abstract

Techniques to dynamically discover and manage page fragments, e.g., to provide a dynamic application user interface, are disclosed. In various embodiments, an indication to add a fragment dynamically to a current application page is received. The fragment to be added is determined, in response to the indication, and added dynamically to the current application page.

Claims

1. A method of providing a dynamic application user interface, comprising:

receiving an indication to add a fragment dynamically to a current application page at runtime;

in response to the indication, determining the fragment to be added, wherein determining the fragment to be added includes

identifying at runtime a user-composed expression associated with the current application page, wherein the user-composed expression is defined by a developer at development time, and

evaluating the expression associated with the current application page at runtime to discover the fragment to be added, wherein identification of the fragment is dependent upon evaluation of the expression, the expression including page context data of the current application page read from a context data cache; and

adding the determined fragment dynamically to the current application page at runtime.

2. The method of claim 1, wherein receiving the indication to add the fragment dynamically includes receiving a user interface event.

3. The method of claim 2, wherein the fragment to be added is determined dynamically based at least in part on the user interface event.

4. The method of claim 3, wherein the fragment to be added is determined dynamically based at least in part on a payload data comprising the user interface event.

5. The method of claim 1, wherein adding the determined fragment dynamically to the current application page includes retrieving a fragment definition associated with the determined fragment.

6. The method of claim 1, wherein adding the determined fragment dynamically to the current application page includes providing to the fragment an input value required by the fragment.

7. The method of claim 6, wherein the input value required by the fragment is determined based at least in part by a fragment definition associated with the determined fragment.

8. The method of claim 1, wherein the fragment added dynamically to the current application page is configured to publish an event.

9. The method of claim 1, wherein the fragment added dynamically to the current application page is configured to publish an output.

10. The method of claim 9, wherein the output comprises one or more output data values and wherein the method further comprises providing at least a subset of the one or more output data values to one or more other elements of the current application page.

11. The method of claim 10, wherein providing at least the subset of the one or more output data values to one or more other elements of the current application page includes transforming said at least the subset of the one or more output data values.

12. The method of claim 1, wherein the fragment is configured to exhibit a first behavior in a first page context of the current application page and a second behavior in a second page context of the current application page.

13. The method of claim 12, wherein the first behavior includes being rendered visibly in the current application page as displayed and the second behavior includes being at least partly hidden from view in the current application page as displayed.

14. The method of claim 1, wherein receiving the indication to add the fragment dynamically to the current application page comprises receiving an indication to add the fragment dynamically to another fragment comprising the current application page.

15. The method of claim 14, wherein the fragment to be added is defined using the expression and wherein the method further comprises adding a default fragment based on a determination that a valid fragment to be added cannot be determined based on the expression.

16. The method of claim 1, further comprising, creating a page document object model (DOM) of the current application page, wherein adding the determined fragment dynamically to the current application page comprises adding the determined fragment to the page DOM.

17. A system, comprising:

a display;

a processor;

and a non-transitory memory storing instructions executable by the processor to;

receive an indication to add a fragment dynamically at runtime to a current application page displayed on the display;

in response to the indication, determine the fragment to be added, wherein determining the fragment to be added includes identifying at runtime a user-composed expression associated with the current application page, wherein the user-composed expression is defined by a developer at development time, and evaluating the expression associated with the current application page at runtime to discover the fragment to be added, wherein identification of the fragment is dependent upon evaluation of the expression, the expression including page context data of the current application page read from a context data cache, wherein evaluating the expression comprises using the page context data to evaluate the expression; and

add the determined fragment dynamically to the current application page at runtime.

18. The system of claim 17, wherein the fragment to be added is determined dynamically at least in part by evaluating the expression.

19. The system of claim 17, wherein the processor is further configured to retrieve a fragment definition associated with the determined fragment.

20. The system of claim 17, wherein adding the determined fragment dynamically to the current application page comprises adding the determined fragment to a document object model (DOM) of the current application page.

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

receiving an indication to add a fragment dynamically to a current application page at runtime;

in response to the indication, determining the fragment to be added, wherein determining the fragment to be added includes identifying at runtime a user-composed expression associated with the current application page, wherein the user-composed expression is defined by a developer at development time, and evaluating the expression associated with the current application page at runtime to discover the fragment to be added, wherein identification of the fragment is dependent upon evaluation of the expression, the expression including page context data of the current application page read from a context data cache, wherein evaluating the expression comprises using the page context data to evaluate the expression; and

adding the determined fragment dynamically to the current application page at runtime.

22. The computer program product of claim 21, wherein adding the determined fragment dynamically to the current application page comprises adding the determined fragment to a document object model (DOM) of the current application page.
