Abstract

Representative implementations provide devices and techniques for automatically generating a skeleton of at least a portion of a web service application. The skeleton comprises a framework that may be modified as needed for a desired use, such as for a relational database backed application, for example. In one aspect, the framework includes a versatile model to support different validation methods and varied customization. Filter support allows a user to perform actions on and/or define rules for inputs. In another aspect, the skeleton is automatically activated in an in-memory database repository.

Claims

1. Computer-readable storage media, having computer-executable instructions stored thereon, that when executed, cause a computer processor to initiate:

receiving a service call request via a user interface;

transforming the request to conform to a customizable framework;

modifying the customizable framework with user-customized route tables, validation methods, and/or filtering components;

importing the customizable framework;

automatically generating a skeleton of a web service application component via a scaffold service, based on the framework; and

automatically activating the skeleton of the web service application component in an in-memory database repository.

2. The computer-readable storage media of claim 1, further comprising displaying a representation of a response object of the web service application component via the user interface.

3. A method, comprising:

receiving a service call request via a user interface;

transforming the request to conform to a customizable framework;

importing the customizable framework; and

automatically generating a skeleton of a web service application component based on the customizable framework.

4. The method of claim 3, further comprising automatically generating the skeleton of the web service application component via a scaffold service.

5. The method of claim 4, further comprising generating the scaffold service using the customizable framework.

6. The method of claim 3, further comprising importing one or more additional frameworks arranged to interact with the customizable framework.

7. The method of claim 3, further comprising modifying the customizable framework with user-customized validation and/or filtering components.

8. The method of claim 3, further comprising automatically activating the skeleton of the web service application component in an in-memory database repository.

9. The method of claim 3, further comprising:

receiving the request from a client;

rewriting the request to a framework-compliant format;

automatically parsing the rewritten request into request components;

determining a request action from the request components;

looking up the request action in one or more route tables;

applying predefined and/or user-defined filters to the request action;

de-serializing a payload of the request to an object;

validating one or more fields of the object;

invoking the request action, based on the object, when the object is valid;

serializing a response object to a string; and

sending the serialized response object to the client.

10. The method of claim 9, further comprising composing rewrite rules for rewriting the request, via the user interface.

11. The method of claim 9, further comprising registering one or more method calls corresponding to potential request actions to the one or more route tables.

12. The method of claim 9, further comprising throwing an exception when the request action is not present in the one or more route tables.

13. The method of claim 9, further comprising checking, via the filters, whether the request action of a user has required privileges for execution.

14. The method of claim 9, further comprising implementing user-customized logic and/or a stored procedure with regard to the request action and the object to determine the response object.

15. The method of claim 9, further comprising setting a content-type of the response object.

16. The method of claim 9, further comprising displaying a representation of the response object via the user interface.

17. A system, comprising:

a user interface;

an input/output module arranged to receive a service call request via the user interface;

a control module including a processor and a non-transitory memory storage device communicatively coupled to the processor;

a customizable framework arranged to provide operations, validation, and filtering; and

a scaffold service component comprising processor-executable instructions stored in the memory storage device and operative on the processor to automatically generate a skeleton of a web service application component based on the service call request and the customizable framework.

18. The system of claim 17, wherein the framework is arranged to support different predetermined and/or user-defined method calls, validation methods, and filter rules.

19. The system of claim 17, wherein the scaffold service is arranged to automatically activate the skeleton of the web service application component in an in-memory database repository.

20. The system of claim 17, wherein the web service application comprises a REST-based relational database type web service application.
