Abstract

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for operating a user application including a user rendered context operating on a user device and maintaining a current render tree, and a user programmer context operating on a cloud computing system. The user rendered context of the user application can receive an input; and send, responsive to receiving the input, an event notification to the user programmer context of the user application. The user rendered context can further receive, from the user programmer context, a difference tree to update the current render tree, and update the current render tree based on the difference tree.

First claim

What is claimed is:

1. A method for operating a user application, comprising:
receiving, by a user rendered context of the user application, an input, wherein the user rendered context operates on a user device and maintains a current render tree, the user rendered context includes an application user interface presented within a user renderer frame on a display of the user device, and generates drawing instructions to an abstracted two dimensional drawing surface without running HyperText Markup Language (HTML) in a browser;
responsive to receiving the input, sending an event notification to a user programmer context of the user application, wherein the user programmer context operates on a cloud computing system, the user application is different from a web application and includes the user rendered context and the user programmer context, and the user rendered context starts operation on the user device after the user programmer context is initialized on the cloud computing system;
receiving, from the user programmer context, a difference tree to update the current render tree; and
updating, by the user rendered context, the current render tree based on the difference tree.

2. The method of claim 1 , wherein the user programmer context is a part of the user application that is executed in the cloud computing system and is responsible for operations related to business logic, application flow, data model, or responses to user navigations.

3. The method of claim 1 , wherein the user rendered context is executed on the user device and is responsible for providing input or output functions for the user application.

4. The method of claim 1 , wherein the user rendered context includes an application user interface presented within a user rendered frame on the display of the user device.

5. The method of claim 4 , wherein the user renderer frame is contained within a root window of a graphical user interface (GUI) for a web browser installed on the user device.

6. The method of claim 1 , wherein the user application is written in one language for both the user rendered context and the user programmer context.

7. The method of claim 1 , wherein the difference tree received from the user programmer context operated in the cloud computing system is represented by JavaScript Object Notation (JSON).

8. The method of claim 1 , wherein the user rendered context includes one or more small components, and a small component is responsible for low-level behavior including key responses, animations, or graphical appearance.

9. The method of claim 1 , wherein the user rendered context is initialized with an initial render tree provided from the user programmer context.

10. A user device, comprising:
at least one processor; and
a user rendered context of a user application operated by the at least one processor, wherein the user rendered context operates on the user device and maintains a current render tree, the user rendered context includes an application user interface presented within a user renderer frame on a display of the user device, and generates drawing instructions to an abstracted two dimensional drawing surface without running HyperText Markup Language (HTML) in a browser, and the user rendered context is configured to:
receive an input;
responsive to receiving the input, send an event notification to a user programmer context of the user application, wherein the user programmer context operates on a cloud computing system, the user application is different from a web application and includes the user rendered context and the user programmer context, and the user rendered context starts operation on the user device after the user programmer context is initialized on the cloud computing system;
receive, from the user programmer context, a difference tree to update the current render tree maintained by the user rendered context; and
update the current render tree based on the difference tree.

11. The user device of claim 10 , wherein the user renderer context is executed on the user device and is responsible for providing input or output functions for the user application, and the user programmer context is a part of the user application that is executed in the cloud computing system and is responsible for operations related to business logic, application flow, data model, or responses to user navigations.

12. The user device of claim 10 , wherein the user renderer context includes an application user interface presented within a user rendered frame on the display of the user device.

13. The user device of claim 12 , wherein the user renderer frame is contained within a root window of a graphical user interface (GUI) for a web browser installed on the user device.

14. The user device of claim 10 , wherein the user rendered context is written in a same language as the user programmer context.

15. The user device of claim 10 , wherein the difference tree received from the user programmer context operated in the cloud computing system is represented by JavaScript Object Notation (JSON).

16. The user device of claim 10 , wherein the user rendered context includes one or more small components, and a small component is responsible for low-level behavior including key responses, animations, or graphical appearance.

17. The user device of claim 10 , wherein the user rendered context is initialized with an initial render tree provided from the user programmer context.

18. A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least a computing device, cause the computing device to perform operations comprising:
receiving, by a user rendered context of a user application, an input, wherein the user rendered context operates on the computing device and maintains a current render tree, the user rendered context includes an application user interface presented within a user renderer frame on a display of a user device, and generates drawing instructions to an abstracted two dimensional drawing surface without running HyperText Markup Language (HTML) in a browser;
responsive to receiving the input, sending an event notification to a user programmer context of the user application, wherein the user programmer context operates on a cloud computing system, the user application is different from a web application and includes the user rendered context and the user programmer context, and the user rendered context starts operation on the user device after the user programmer context is initialized on the cloud computing system;
receiving, from the user programmer context, a difference tree to update the current render tree; and
updating, by the user rendered context, the current render tree based on the difference tree.

19. The non-transitory computer-readable medium of claim 18 , wherein the user rendered context is executed on the computing device and is responsible for providing input or output functions for the user application, and the user programmer context is a part of the user application that is executed in the cloud computing system and is responsible for operations related to business logic, application flow, data model, or responses to user navigations.

20. The non-transitory computer-readable medium of claim 18 , wherein the user rendered context is initialized with an initial render tree provided from the user programmer context.
