Abstract

A method and apparatus for providing real-time web applications is described. In one embodiment, the method includes obtaining data for a topic with a server computer system. The method may also include determining a client that is rendering a framework widget with a subscription to the topic. In one embodiment, the method may further include transmitting a message including the data from an application framework to the client to enable the framework widget to process the data, the message transmitted to the client without the client issuing a request for an update.

Claims

1. A computer-implemented method comprising:

obtaining data for a topic with a server computer system;

determining a client that is rendering a framework widget with a subscription to the topic; and

transmitting a message including the data from an application framework to the client to enable the framework widget to process the data, the message transmitted to the client without the client issuing a request for an update.

2. The method of claim 1, further comprising:

receiving a request from the client for a web page including the framework widget, the widget including a subscription to the topic;

dynamically injecting a framework socket into the requested web page prior to delivery to the client, the framework socket creating an open communications pathway between the client and a message broker.

3. The method of claim 2, further comprising:

receiving a subscription to the topic transmitted from the dynamically injected framework socket.

4. The method of claim 2, further comprising:

dynamically injecting application code into the framework widget while the framework widget is transmitted to the client.

5. The method of claim 4, wherein the dynamically injected application code corresponds to one or more pointers, stored by the framework widget, that point to snippets of logic stored by a real-time web application framework.

6. The method of claim 4, wherein the application code includes logic for the display of the received message.

7. The method of claim 1, further comprising:

receiving the message including the data at a framework socket open in a client, the framework socket enabling a live communications link between the framework widget and a message broker;

determining one or more framework widgets displayed in a web page with subscriptions to the topic; and

the framework socket routing the message including the data to only the framework widgets with corresponding topic subscriptions.

8. The method of claim 7, further comprising

responsive to receiving the message routed by the framework socket, executing one or more callback functions to process the data message.

9. The method of claim 1, wherein the data is obtained by a hub of a real-time web application framework, the hub executing plug-in applications outside of a web stack managed by the real-time web application framework.

10. The method of claim 1, wherein the message is transmitted to the client in real-time and without receiving a request from the web browser for the data.

11. A computer readable storage medium that provides instructions, which when executed on a processing system cause the processing system to perform a method comprising:

obtaining data for a topic with a server computer system;

determining a client that is rendering a framework widget with a subscription to the topic; and

transmitting a message including the data from an application framework to the client to enable the framework widget to process the data, the message transmitted to the client without the client issuing a request for an update.

12. The computer readable storage medium of claim 11, further comprising:

receiving a request from a client for a web page including the framework widget, the widget including a subscription to the topic;

dynamically injecting a framework socket into the requested web page prior to delivery to the client, the framework socket creating an open communications pathway between the client and a message broker.

13. The computer readable storage medium of claim 12, further comprising:

receiving a subscription to the topic transmitted from the dynamically injected framework socket.

14. The computer readable storage medium of claim 12, further comprising:

dynamically injecting application code into the framework widget while the framework widget is transmitted to the client.

15. The computer readable storage medium of claim 14, wherein the dynamically injected application code corresponds to one or more pointers, stored by the framework widget, that point to snippets of logic stored by a real-time web application framework.

16. The computer readable storage medium of claim 14, wherein the application code includes logic for the display of the received message.

17. The computer readable storage medium of claim 11, further comprising:

receiving the message including the data at a framework socket open in a client, the framework socket enabling a live communications link between the framework widget and a message broker;

determining one or more framework widgets displayed in a web page with subscriptions to the topic; and

the framework socket routing the message including the data to only the framework widgets with corresponding topic subscriptions.

18. The computer readable storage medium of claim 17, further comprising

responsive to receiving the message routed by the framework socket, executing one or more callback functions to process the data message.

19. The computer readable storage medium of claim 11, wherein the data is obtained by a hub of a real-time web application framework, the hub executing plug-in applications outside of a web stack managed by the real-time web application framework, and wherein the message is transmitted to the client in real-time and without receiving a request from the web browser for the data.

20. A system, comprising:

a memory; and

a processor coupled with the memory to

obtain data for a topic with a server computer system;

determine a client that is rendering a framework widget with a subscription to the topic; and

transmit a message including the data from an application framework to the client to enable the framework widget to process the data, the message transmitted to the client without the client issuing a request for an update.
