Abstract

Systems and methods are described which provide improved memory and resource allocation for content pages accessed using a browser. A content page may be accessed and compiled into machine code, such as executable files or an application. The machine code may then be executed on a user device in a process separate from the browser to cause display of the content page, such as in a standalone application. Content pages may be pre-compiled and provided in response to user requests to access the content pages. A content page may be compiled faster than the browser may process the native content page, and the compiled machine code may require less memory than the native content page and associated resources. In some embodiments an intermediary system may be used to perform content page compilation and may provide the compiled machine code, instead of the native content, to the user device.

Claims

re-compiling at least a portion of the content page based on information indicating detected changes to the content page.

2. The method of claim 1, wherein the machine code representing the content page comprises one or more executable files or a standalone application.

3. The method of claim 1, wherein the target platform is determined based at least in part on one or more device attributes accessed from the user computing device.

4. The method of claim 1, wherein the one or more content resources associated with the content page includes one or more of hypertext markup language files, JavaScript files, cascading style sheet files, image files, or media content files.

5. A system comprising:

an intermediary system comprising computer hardware configured to at least;

retrieve a content page from a host system, the content page comprising associated metadata descriptive of one or more content resources associated with the content page;

provide, to a user computing device, the compiled code version of the content page, the user computing device configured to cause the compiled code version of the content page to be executed by an operating system installed on the user computing device in a separate process,

wherein at least a portion of the content page is re-compiled based on information indicating detected changes to the content page.

6. The system of claim 5, wherein the content page is retrieved on behalf of the user computing device in response to a request for the content page, the request received by the intermediary system.

7. The system of claim 6, wherein the target platform is determined based in part on one or more device attributes received with the request for the content page.

8. The system of claim 5, wherein the one or more content resources associated with the content page includes at least one of a hypertext markup language file, a JavaScript file, a cascading style sheet file, an image file, or a media content file.

9. The system of claim 5, wherein the machine code comprises one or more executable files.

10. The system of claim 5, wherein the machine code is a standalone application.

11. The system of claim 5, wherein to generate the compiled code version of the content page and the one or more content resources associated with the content page, the intermediary system is further configured to:

link, with the content page, the code library executable on the target platform; and

compile the content page, the one or more content resources, and the code library into an executable application.

12. The system of claim 11, wherein the code library is selected based at least in part on the associated metadata for the content page.

13. The system of claim 5, wherein the content page is accessed independently of a request for the content page.

14. The system of claim 5, wherein the intermediary system is further configured to:

receive, from the user computing device, user interaction data indicative of a state change for a respective portion of the content page;

generate, based on the user interaction data, a re-compiled code version of the content page and the one or more content resources associated with the content page; and

provide to the user computing device, the re-compiled code version of the content page, the user computing device configured to cause the re-compiled code version of the content page to be executed by the operating system installed on the user computing device in the separate process.

15. A method of providing a content page, the method comprising:

accessing, by an intermediary computing system comprising computer hardware, a content page from a host system, the content page comprising associated metadata descriptive of one or more content resources associated with the content page;

determining a target platform for which a compiled code version of the content page is to be generated, wherein a code library is selected for compilation based, at least in part, on the target platform

generating, according to the determined target platform, the compiled code version of the content page and the one or more content resources associated with the content page, the compiled code version comprising machine code representative of the content page, the machine code configured for execution on the target platform; and

responsive to a request for the content page received from a user computing device, providing, to the user computing device, the compiled code version of the content page for execution by an operating system installed on the user computing device,

wherein at least a portion of the content page is re-compiled based on information indicating detected changes to the content page.

16. The method of claim 15, wherein the target platform specifies at least a target device type and a target operating system.
