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 method comprising:

obtaining, by a processing device of a server computer system, data for a topic associated with a message queue;

identifying, by the processing device, a client rendering a framework widget corresponding to a client web application, the framework widget to subscribe to the message queue for the topic; and

transmitting, by the processing device to the client without the client requesting an update for the client web application, a message comprising the topic data, wherein the message to enable the framework widget to process the data and to update the client web application using the data.

2. The method of claim 1, further comprising:

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

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:

transmitting a message associated with a subscription using 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 comprises logic for the display of the received message.

7. The method of claim 1, further comprising:

receiving the message comprising 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

routing, by the framework socket, the message comprising 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 non-transitory computer readable storage medium that provides instructions, which when executed on a processing device cause the processing device to perform a method comprising:

obtaining, by the processing device of a server computer system, data for a topic associated with a message queue;

identifying, by the processing device, a client rendering a framework widget corresponding to a client web application, the framework widget to subscribe to the message queue for the topic; and

transmitting, by the processing device to the client without the client requesting an update for the client web application, a message comprising the topic data, wherein the message to enable the framework widget to process the data and to update the client web application using the data.

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

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

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 non-transitory computer readable storage medium of claim 12, further comprising:

transmitting a message associated with a subscription using the dynamically injected framework socket.

14. The non-transitory 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 non-transitory 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 non-transitory computer readable storage medium of claim 14, wherein the application code comprises logic for the display of the received message.

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

receiving the message comprising 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

routing, by the framework socket, the message comprising the data to only the framework widgets with corresponding topic subscriptions.

18. The non-transitory 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 non-transitory 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;

a processing device coupled with the memory; and

an application framework executed from the memory by the processing device, the application framework to;

obtain data for a topic associated with a message queue;

identify a client rendering a framework widget corresponding to a client web application, the framework widget to subscribe to the message queue for the topic; and

transmit a message to the client without the client requesting an update for the client web application, the message comprising the topic data, wherein the message is to enable the framework widget to process the data and to update the client web application using the data.

21. The system of claim 20, wherein the application framework further to:

receive a request from the client for a web page comprising the framework widget, the widget comprising a subscription to the topic; and

dynamically inject 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.

22. The system of claim 20, wherein the application framework further to:

receive the message comprising 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; and

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

wherein the framework socket to route the message comprising the data to only the framework widgets with corresponding topic subscriptions.
