Abstract

Application code for deployment to a client over a data link is optimized to minimize download time by supplying only the application code with a particular object that is required by the object. In a web application that includes multiple pages, the HTML and JAVASCRIPT are scanned to identify code resources called by a particular web page. When all called resources are identified, they are extracted and concatenated into a single resource file. When the page is downloaded to the client, the import file is included with the page. The import file may be cached so that it need only be downloaded once, rather than being downloaded every time the page is requested. The invention is suitable for use with other interpreted scripting languages.

Claims

1. A method comprising:

locating a first entry point and a second entry point into hyper-text markup language code associated with a web page;

identifying a first resource associated with the first entry points and a second resource associated with the second entry point;

generating, by at least one server, a first resource information object associated with the first resource and a second resource information object associated with the second resource, the first resource information object containing code that implements the first resource and the second resource information object containing code that implements the second resource; and

upon determining that the first resource is used by the web page and the second resource is not used by the web page, sending the first resource information object to a client device in response to a request from the client device to access the web page.

2. The method as recited in claim 1, wherein locating the first entry point into the hyper-text markup language code associated with the web page comprises scanning the hyper-text markup language code for one or more of hyper-text markup language tags that incorporate Javascript statements, actions associated with various web page elements, or document object model events.

3. The method as recited in claim 1, wherein generating the first resource information object associated with the first resource comprises creating a data structure with one or more of a resource name field, a method called by the resource field, a code implementing the resource field, a source file for the resource field, an is-used field, and an is-real field.

4. The method as recited in claim 3, wherein the code implementing the resource field and the source file for the resource field are optionally included in the data structure.

5. The method as recited in claim 1, further comprising:

identifying, by the at least one server, one or more first external code resources referenced by the web page hosted by the at least one server, wherein identifying one or more first external code resources referenced by the web page comprises identifying markup language code and one or more scripting language code blocks referenced by the web page; and

bundling, by the at least one server, the one or more first external code resources and the first resource information object into an import file, wherein sending the first resource information object to the client device in response to the request from the client device to access the web page comprises sending the import file to the client device.

6. The method as recited in claim 1, further comprising adding the first resource information object to an aggregated list of resource information objects associated with the first entry point.

7. The method as recited in claim 6, wherein the aggregated list of resource information objects is a hash map with associated hash map keys and hash map values, wherein:

the hash map keys comprise one or more resource names, and

the hash map values comprise one or more resource information objects corresponding to the one or more resource names.

8. The method as recited in claim 7, wherein sending the first resource information object to the client device further comprises sending the aggregated list of resource information objects associated with the first entry point without sending the second resource information object.

9. The method as recited in claim 8, wherein sending the aggregated list of resource information objects further comprises:

identifying a value associated with an is-used field associated with each resource information object in the aggregated list of resource information objects; and

sending each resource information object based on the identified value associated with the is-used field associated with each resource information object.

10. A system comprising:

at least one processor; and

at least one non-transitory computer-readable storage medium storing instructions thereon that, when executed by the at least one processor, cause the system to;

locate a first entry point and a second entry point into hyper-text markup language code associated with a web page;

identify a first resource associated with the first entry point and a second resource associated with the second entry point;

generate a first resource information object associated with the first resource and a second resource information object associated with the second resource, the first resource information object containing code that implements the first resource and the second resource information object containing code that implements the second resource; and

upon determining that the first resource is used by the web page and the second resource is not used by the web page, send the first resource information object to a client device in response to a request from the client device to access the web page.

11. The system as recited in claim 10, wherein locating the first entry point into the hyper-text markup language code associated with the web page comprises scanning the hyper-text markup language code for one or more of hyper-text markup language tags that incorporate Javascript statements, actions associated with various web page elements, or document object model events.

12. The system as recited in claim 10, wherein generating the first resource information object associated with the first resource comprises creating a data structure with one or more fields associated with one or more of a resource name field, a method called by the resource field, a code implementing the resource field, a source file for the resource field, an is-used field, and an is-real field.

13. The system as recited in claim 12, wherein the code implementing the resource field and the source file for the resource field are optionally included in the data structure.

14. The system as recited in claim 10, further comprising instructions that, when executed by the at least one processor, cause the system to add the first resource information object to an aggregated list of resource information objects associated with the first entry point.

15. The system as recited in claim 14, wherein the aggregated list of resource information objects is a hash map with associated hash map keys and hash map values, wherein:

the hash map keys comprise one or more resource names, and

the hash map values comprise one or more resource information objects corresponding to the one or more resource names.

16. The system as recited in claim 15, wherein sending the first resource information object to the client device further comprises sending the aggregated list of resource information objects associated with the first entry point without sending the second resource information object.

17. The system as recited in claim 16, wherein sending the aggregated list of resource information objects further comprises:

identifying a value associated with an is-used field associated with each resource information object in the aggregated list of resource information objects; and

sending each resource information object based on the identified value associated with the is-used field associated with each resource information object.

18. The system as recited in claim 10, further comprising instructions that, when executed by the at least one processor, cause the system to:

identify one or more first external code resources referenced by the web page, wherein identifying one or more first external code resources referenced by the web page comprises identifying markup language code and one or more scripting language code blocks referenced by the web page; and

bundle the one or more first external code resources and the first resource information object into an import file, wherein sending the first resource information object to the client device in response to the request from the client device to access the web page comprises sending the import file to the client device.

19. A non-transitory computer readable medium storing instructions thereon that, when executed by at least one processor, cause a computer system to:

locate a first entry point and a second entry point into hyper-text markup language code associated with a web page;

identify a first resource associated with the first entry point and a second resource associated with the second entry point;

generate a first resource information object associated with the first resource and a second resource information object associated with the second resource, the first resource information object containing code that implements the first resource and the second resource information object containing code that implements the second resource; and

upon determining that the first resource is used by the web page and the second resource is not used by the web page, send the first resource information object to a client device in response to a request from the client device to access the web page.

20. The non-transitory computer readable medium as recited in claim 19, wherein generating the first resource information object associated with the first resource comprises creating a data structure with one or more of a resource name field, a method called by the resource field, a code implementing the resource field, a source file for the resource field, an is-used field, and an is-real field.
