Abstract

Described is a mechanism for enabling an application operating as a web application to transition to a client-side application without impacting a user'"'"'s interaction with the application. The progressive installation transitions through three states: a start-up state, a demand state, and an install state. During the start-up state, a subset of components associated with the application is downloaded and stored in a local data store. The subset is sufficient to allow execution of the application in a manner similar to a web application. During the demand state, additional resources associated with the application are downloaded. Transitioning from the demand state to the installed state occurs without impacting a user'"'"'s interaction with the application. The transition may occur autonomously based on the number of additional resources stored in the local data store or upon an external trigger.

Claims

1. A computer-readable storage medium encoded with computer-executable instructions configured to perform a computer-implemented method, comprising:

Identifying an application package associated with an application, the application package including sufficient resources to enable user interaction with the application;

downloading content of the application package to a local store, the content being less than the full application;

upon receiving a request for one of a plurality of additional resources associated with the application, downloading the additional resource, the request for one of a plurality of additional resources being made without corresponding user action; and

upon receiving a request to transition the application to a client-side full application, downloading remaining resources to the local store, the request to transition the application to a client-side full application being made without corresponding user action.

2. The computer-readable storage medium of claim 1, wherein identifying of the application package comprises activating a hyperlink associated with the application.

3. The computer-readable storage medium of claim 1, wherein identifying of the application package further comprises initiating retrieval of a deployment manifest that identifies the application package.

4. The computer-readable storage medium of claim 1, wherein a subset of components is identified by the application package.

5. The computer-readable storage medium of claim 1, wherein the application package comprises an application manifest and code.

6. The computer-readable storage medium of claim 1, wherein the application package is in an executable format.

7. The computer-readable storage medium of claim 1, the computer-implemented method further comprising downloading an additional resource associated with the application upon activation of a hyperlink on a Web page associated with the application.

8. The computer-readable storage medium of claim 7, wherein the additional resource comprises an on demand resource.

9. The computer-readable storage medium of claim 8, the computer-implemented method further comprising storing the on demand resource to the local data store.

10. The computer-readable storage medium of claim 7, wherein the additional resource comprises an online resource.

11. The computer-readable storage medium of claim 10, the computer-implemented method further comprising storing the online resource in a transient cache.

12. The computer-readable storage medium of claim 11, wherein transitioning the application to the installed full application comprises storing the online resource in the local data store.

13. The computer-readable storage medium of claim 1, wherein transitioning the application to the installed full application comprises downloading a plurality of remaining resources to the local data store, the plurality of remaining resources being components that are not currently in the local data store.

14. The computer-readable storage medium of claim 1, wherein transitioning the application to the installed full application comprises transferring a state associated with the application to the installed full application in a manner such that when the installed full application is launched offline, execution of the installed full application resumes at the state associated with the application.

15. The computer-readable storage medium of claim 14, wherein the state information is stored in an application object associated with the application.

16. A computer-executable method for transitioning a web application to a client-side full application, comprising:

identifying an application package associated with an application, the application package including sufficient resources to enable user interaction with the application;

downloading content of the application package to a local store, the content being less than the full application;

upon receiving a request for one of a plurality of additional resources associated with the application, downloading the additional resource, the request for one of a plurality of additional resources being made without corresponding user action; and

upon receiving a request to transition the application to a client-side full application, downloading remaining resources to the local store, the request to transition the application to a client-side full application being made without corresponding user action.

17. The computer-executable method of claim 16, wherein the request to transition the application to the client-side full application is based on the number of additional resources currently stored in the local store.

18. The computer-executable method of claim 17, wherein the request to transition the application occurs autonomously.

19. The computer-executable method of claim 16, wherein the application package includes an application manifest and code, the application manifest uniquely identifying a subset of resources associated with the application.

20. The computer-executable method of claim 19, wherein the application comprises the subset of resources and the plurality of additional resources.

21. The computer-executable method of claim 20, wherein downloading the additional resource further comprises storing the additional resource in the local store if the additional resource comprises an on demand resource, and storing the additional resource in a transient cache if the additional resource comprises an online resource.

22. The computer-executable method of claim 16, further comprising determining whether the additional resource is available locally, and if so, using the local additional resource rather than downloading the additional resource.

23. The computer-executable method of claim 16, wherein the remaining resources are an additional subset out of the plurality of additional resources that are not currently stored in the local store.

24. The computer-executable method of claim 16, wherein transitioning the application to the client-side full application comprises transferring a state associated with the application to the client-side full application in a manner such that when the client-side full application is launched offline, execution of the client-side full application resumes at the state associated with the application when transitioned.

25. The computer-executable method of claim 16, wherein the state information is stored in an application object associated with the application.
