Abstract

Disclosed are methods, systems, and computer program products for updating a web application displayed on a client machine. In some implementations, a server maintains a database of application identifiers identifying instances of one or more web applications. The server receives, from a first client machine, a communication identifying a first web application and a first application identifier, the instance of the first web application being associated with one or more components. The server determines that the first application identifier is not included in the database of application identifiers, and generates an updated application identifier for the instance of the first web application based on component version identifiers of the one or more components. The server stores the updated application identifier and transmits a notification to the first client machine indicating that the instance of the first web application is out-of-date.

Claims

1. A system comprising:

a database system implemented using a server system comprising one or more processors, the database system configurable to cause;

maintaining, using the database system, a database of application identifiers identifying a plurality of web applications including a first web application being displayable at a first client machine, the first web application comprising a plurality of components, each component having a component version identifier indicating a version of the component, the first web application being identified by a first application identifier generated based on a calculation of each component version identifier of the components;

identifying, using the database system, a first component version identifier of a first one of the components, the first component capable of being stored in a cache of the first client machine;

processing a notification indicating that the first component has been updated, the updated first component having an updated component version identifier;

processing a request associated with the first web application from the first client machine;

identifying, using the database system, a set of component version identifiers associated with each component of the first web application, the identified set of component version identifiers comprising the updated component version identifier;

generating, using the database system, a second application identifier by traversing a dependency tree of the components to compute a hash of the identified set of component version identifiers of the components of the dependency tree;

determining, using the database system, that the first application identifier is different from the second application identifier;

storing the second application identifier as one of the application identifiers in the database; and

transmitting a notification indicating that the first web application is out-of-date, the notification comprising the second application identifier.

2. The system of claim 1, wherein the determination that the first application identifier is different from the second application identifier indicates that an instance of the first web application on the first client machine comprises at least one out-of-date component.

3. The system of claim 1, the database system further configurable to cause:

transmitting a response to the first client machine, the response comprising an identifier for the first component to be included in an updated instance of the first web application.

4. The system of claim 3, the database system further configurable to cause:

processing a component request for a definition of a component; and

transmitting an updated component definition to the first client machine to be rendered in a user interface at the first client machine.

5. The system of claim 1, wherein maintaining the database of application identifiers comprises:

determining that a component has been updated;

identifying, using the database system, one or more application identifiers associated with web applications comprising the updated component; and

removing the identified application identifiers from the database.

6. The system of claim 5, wherein determining that a component has been updated comprises receiving a notification from a component database that a component has been updated, the notification comprising an updated component version identifier, and wherein the updated application identifier is generated based in part on the updated component version identifier for the updated component.

7. The system of claim 1, wherein the first component is selected from a set of components associated with the first web application based on one or more criteria, the one or more criteria comprising one or more of:

a role of a user of the first web application, a position of the user, or a personalization setting of the user.

8. The system of claim 1, wherein the request is an XHR (XMLHttpRequest) request configured to trigger an action on the one or more servers.

9. The system of claim 1, wherein the second application identifier is stored and indexed in the database according to an attribute of the first web application, the attribute being an application name or an application descriptor.

10. A method comprising:

maintaining, using a database system, a database of application identifiers identifying a plurality of web applications including a first web application being displayable at a first client machine, the first web application comprising a plurality of components, each component having a component version identifier indicating a version of the component, the first web application being identified by a first application identifier generated based on a calculation of each component version identifier of the components;

identifying, using the database system, a first component version identifier of a first one of the components, the first component capable of being stored in a cache of the first client machine;

processing a notification indicating that the first component has been updated, the updated first component having an updated component version identifier;

processing a request associated with the first web application from the first client machine;

identifying, using the database system, a set of component version identifiers associated with each component of the first web application, the identified set of component version identifiers comprising the updated component version identifier;

generating, using the database system, a second application identifier by traversing a dependency tree of the components to compute a hash of the identified set of component version identifiers of the components of the dependency tree;

determining, using the database system, that the first application identifier is different from the second application identifier;

storing the second application identifier as one of the application identifiers in the database; and

transmitting a notification indicating that the first web application is out-of-date, the notification comprising the second application identifier.

11. The method of claim 10, wherein the determination that the first application identifier is different from the second application identifier indicates that an instance of the first web application on the first client machine comprises at least one out-of-date component.

12. The method of claim 10, the method further comprising:

transmitting a response to the first client machine, the response comprising an identifier for the first component to be included in an updated instance of the first web application.

13. The method of claim 12, the method further comprises:

processing a component request for a definition of a component; and

transmitting an updated component definition to the first client machine to be rendered in a user interface at the first client machine.

14. A computer program product comprising computer-readable program code to be executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code including instructions configured to cause:

maintaining, using a database system, a database of application identifiers identifying a plurality of web applications including a first web application being displayable at a first client machine, the first web application comprising a plurality of components, each component having a component version identifier indicating a version of the component, the first web application being identified by a first application identifier generated based on a calculation of each component version identifier of the components;

identifying, using the database system, a first component version identifier of a first one of the components, the first component capable of being stored in a cache of the first client machine;

processing a notification indicating that the first component has been updated, the updated first component having an updated component version identifier;

processing a request associated with the first web application from the first client machine;

identifying, using the database system, a set of component version identifiers associated with each component of the first web application, the identified set of component version identifiers comprising the updated component version identifier;

generating, using the database system, a second application identifier by traversing a dependency tree of the components to compute a hash of the identified set of component version identifiers of the components of the dependency tree;

determining, using the database system, that the first application identifier is different from the second application identifier;

storing the second application identifier as one of the application identifiers in the database; and

transmitting a notification indicating that the first web application is out-of-date, the notification comprising the second application identifier.

15. The computer program product of claim 14, wherein the determination that the first application identifier is different from the second application identifier indicates that an instance of the first web application on the first client machine comprises at least one out-of-date component.

16. The computer program product of claim 14, the instructions further configured to cause:

transmitting a response to the first client machine, the response comprising an identifier for the first component to be included in an updated instance of the first web application.

17. The computer program product of claim 16, the instructions further configured to cause:
