Abstract

Systems, devices, and methods for providing a development environment for cloud-based, data-driven software applications are presented. On a client device, an execution platform may provide a graphical user interface (GUI) through which a software designer can visually develop an application. The execution platform may represent the application as an application model and a data model. The application model may contain information related to pages and program logic that make up the application, and the data model may contain information stored and used by the application. Both the application model and the data model may be updated, in near real-time, as the software designer makes changes to the application.

Claims

1. A method, performed by a computing device, the method comprising:

displaying on the computing device, via a graphical development environment, a user interface of an application, wherein the graphical development environment has access to an application model and a data model, wherein the application model includes program logic of the application and a representation of the user interface of the application, wherein the data model includes a database schema for storing data used by the application, and wherein the graphical development environment is controlled by a script-based execution platform operating on the computing device;

the computing device receiving a change to the user interface of the application; and

in response to receiving the change, the computing device (i) applying a modification to the application model and the data model to incorporate the change, and (ii) automatically transmitting a representation of the modification to a server device, wherein the server device stores copies of the application model and the data model.

2. The method of claim 1, wherein the representation of the user interface comprises a representation of a web page that includes a widget.

3. The method of claim 2, wherein the widget contains text and graphical content, and wherein use of the widget triggers execution of a script.

4. The method of claim 1, wherein an instance of the graphical development environment is in a design mode, wherein the instance of the graphical development environment receives the change to the application, the method further comprising:

based on receiving the change to the user interface of the application, the computing device (i) automatically updating a first instance of the application executing in a preview mode to incorporate the change, and (ii) refraining from updating a second instance of the application executing in a run mode.

5. The method of claim 1, wherein receiving the change to the user interface of the application comprises:

the computing device receiving a script containing additional program logic, wherein the script is associated with a new widget added to the user interface of the application by the change;

in response to receiving the script, the computing device transmitting the script to the server device;

after transmitting the script to the server device, the computing device receiving a compiled version of the script from the server device; and

in response to receiving the compiled version of the script from the server device, the computing device adding the compiled version of the script to the program logic of the application.

6. The method of claim 5, wherein the script controls a value of at least one unit of data stored in the database schema.

7. The method of claim 5, wherein adding the compiled version of the script to the program logic of the application comprises:

the computing device storing the compiled version of the script in a compiled scripts module of the application; and

the computing device linking the program logic of the application to the additional program logic of the compiled script via a script callbacks module.

8. An article of manufacture including a non-transitory computer-readable medium, having stored thereon program instructions that, if executed by a computing device, cause the computing device to perform operations comprising:

displaying, via a graphical development environment, a user interface of an application, wherein the graphical development environment has access to an application model and a data model, wherein the application model includes program logic of the application and a representation of the user interface of the application, wherein the data model includes a database schema for storing data used by the application, and wherein the graphical development environment is controlled by a script-based execution platform operating on the computing device;

receiving a change to the user interface of the application; and

in response to receiving the change, (i) applying a modification to the application model and the data model to incorporate the change, and (ii) automatically transmitting a representation of the modification to a server device, wherein the server device stores copies of the application model and the data model.

9. The article of manufacture of claim 8, wherein the representation of the user interface comprises a representation of a web page that includes a widget.

10. The article of manufacture of claim 9, wherein the widget contains text and graphical content, and wherein use of the widget triggers execution of a script.

11. The article of manufacture of claim 8, wherein an instance of the graphical development environment is in a design mode, wherein the instance of the graphical development environment receives the change to the user interface of the application, the computer-readable medium, having further stored thereon program instructions that, if executed by a computing device, cause the computing device to perform operations comprising:

based on receiving the change to the user interface of the application, (i) automatically updating a first instance of the application executing in a preview mode to incorporate the change, and (ii) refraining from updating a second instance of the application executing in a run mode.

12. The article of manufacture of claim 8, wherein receiving the change to the user interface of the application comprises:

receiving a script containing additional program logic, wherein the script is associated with a new widget added to the user interface of the application by the change;

in response to receiving the script, transmitting the script to the server device;

after transmitting the script to the server device, receiving a compiled version of the script from the server device; and

in response to receiving the compiled version of the script from the server device, adding the compiled version of the script to the program logic of the application.

13. The article of manufacture of claim 12, wherein the script controls a value of at least one unit of data stored in the database schema.

14. The article of manufacture of claim 12, wherein adding the compiled version of the script to the program logic of the application comprises:

storing the compiled version of the script in a compiled scripts module of the application; and

linking the program logic of the application to the additional program logic of the compiled script via a script callbacks module.

15. A system comprising:

means for displaying on a computing device, via a graphical development environment, a user interface of an application, wherein the graphical development environment has access to an application model and a data model, wherein the application model includes program logic of the application and a representation of the user interface of the application, wherein the data model includes a database schema for storing data used by the application, and wherein the graphical development environment is controlled by a script-based execution platform operating on the computing device;

means for receiving a change to the user interface of the application; and

means for, in response to receiving the user interface of the application, (i) applying a modification to the application model and the data model to incorporate the change, and (ii) automatically transmitting a representation of the modification to a server device, wherein the server device stores copies of the application model and the data model.

16. The system of claim 15, wherein an instance of the graphical development environment is in a design mode, wherein the instance of the graphical development environment receives the change to the user interface of the application, the system further comprising:

means for, based on receiving the change to the user interface of the application, (i) automatically updating a first instance of the application executing in a preview mode to incorporate the change, and (ii) refraining from updating a second instance of the application executing in a run mode.

17. The system of claim 15, wherein receiving the change to the application comprises:
