Abstract

The disclosed embodiments relate to a system that displays diagnostic information to facilitate web page development. While a web page is being assembled at a front-end system using data gathered from one or more back-end systems, the system accumulates metadata associated with the assembly process. Next, the system renders the web page using the gathered data. Finally, the system sends the rendered web page along with the metadata to a browser to be displayed to a user, wherein the browser is configured to selectively display the metadata when the web page is displayed.

Claims

1. A method for displaying diagnostic information to facilitate web page development, comprising:

while a web page is being assembled at a front-end system using data gathered from one or more back-end systems, accumulating metadata associated with the assembly process;

configuring the web page to request and receive JavaScript (JS) code from a content distribution network (CDN), wherein the CDN comprises a distributed set of servers configured to serve content to end-users;

rendering the web page using the gathered data; and

sending the rendered web page to a browser to be displayed to a user, wherein the metadata is sent along with the rendered page, thereby enabling the browser to;

receive from the user a selection of a page element on the rendered web page;

use a string stored within the page element to perform a string search of the metadata to find a subset of metadata associated with the selected page element; and

display the subset of metadata to the user via a pop using the received JS code.

2. The method of claim 1, wherein the metadata includes a call graph that identifies one or more services that were accessed during the assembly process.

3. The method of claim 1, wherein the metadata includes a template which identifies source files that were used to render the web page.

4. The method of claim 1, wherein the metadata additionally includes performance metrics associated with the web page, so that the performance metrics can be selectively displayed when the web page is displayed.

5. The method of claim 1, wherein the metadata identifies currently active A/B tests, inactive A/B tests and associated treatments.

6. The method of claim 1, wherein the metadata includes page-level and page-module-level debugging information.

7. The method of claim 1, wherein upon receiving a request from the browser asking for additional metadata, the method further comprises:

forwarding the request to one or more back-end servers; and

when the additional metadata is received in response to the request from the one or more back-end servers, forwarding the additional metadata to the browser.

8. The method of claim 1, wherein the popup displays metadata associated with one or more elements over which a cursor is positioned in the web page.

9. The method of claim 1, wherein the popup displays metadata associated with one or more keywords entered by the user.

10. The method of claim 1, further comprising:

receiving a cookie from the browser that requests that metadata associated with a page-assembly process be captured; and

in response to receiving the cookie, instructing back-end systems to capture metadata associated with the page-assembly process.

11. A method for displaying diagnostic information to facilitate web page development, comprising:

receiving, at a browser, a web page along with metadata that relates to the process of assembling the web page, wherein the metadata was accumulated while the web page was being assembled at a front-end system using data gathered from one or more back-end systems;

configuring the web page to request and receive JavaScript (JS) code from a content distribution network (CDN), wherein the CDN comprises a distributed set of servers configured to serve content to end-users;

displaying the web page to a user;

receiving from the user a selection of a page element on the web page;

using a string stored within the page element to perform a string search of the metadata to find a subset of metadata associated with the selected page element; and

displaying the subset of metadata to the user via a popup using the received JS code.

12. The method of claim 11, wherein the popup displays metadata associated with one or more elements over which a cursor is positioned in the web page which is controlled by the user.

13. The method of claim 11, wherein the popup displays metadata associated with one or more keywords entered by the user.

14. The method of claim 11, wherein upon receiving a request from the user asking for additional metadata, the method further comprises:

forwarding the request to the front-end server, wherein the front-end server forwards the request to one or more back-end servers; and

when the additional metadata is received from the front-end server and the one or more back-end servers in response to the request, displaying the additional metadata to the user.

15. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for displaying diagnostic information to facilitate web page development, the method comprising:

while a web page is being assembled at a front-end system using data gathered from one or more back-end systems, accumulating metadata associated with the assemble process;

configuring the web page to request and receive JavaScript (JS) code from a content distribution network (CDN), wherein the CDN comprises a distributed set of servers configured to serve content to end-users;

rendering the web page using the gathered data; and

sending the rendered web page to a browser to be displayed to a user, wherein the metadata is sent along with the rendered web page thereby enabling the browser to;

receive from the user a selection of a page element on the rendered web page;

use a string stored within the page element to perform a string search of the metadata to fins a subset of metadata to find a subset of metadata associated with the selected page element; and

display the subset of metadata to the user via a popup using the received JS code.

16. A computer system that facilitates displaying diagnostic information for web page development, comprising:

a hardware module; and

a process, wherein the process is stored in the hardware module and configurable to be executed by the hardware module, configured to;

assemble a web page using data gathered from one or more back-end systems,

accumulate metadata associated with the assembly process,

configure the web page to request and receive JavaScript (JS) code from a content distribution network (CDN), wherein the CDN comprises a distributed set of servers configured to serve content to end-users,

render the web page using the gathered data, and

send the rendered web page to a browser to be displayed to a user, wherein the metadata is sent along with the rendered web page, thereby enabling the browser to;

receive from the user a selection of a page element on the rendered web page;

use a string stored within the page element to perform a string search of the metadata to fins a subset of metadata to find a subset of metadata associated with the selected page element; and

display the subset of metadata to the user via a popup using the received JS code.

17. The computer system of claim 16, wherein the metadata includes a call graph that identifies one or more services that were accessed during the assembly process.

18. The computer system of claim 16, wherein the metadata includes a template which identifies source files that were used to render the web page.

19. The computer system of claim 16, wherein the metadata additionally includes performance metrics associated with the web page, so that the performance metrics can be selectively displayed when the web page is displayed.

20. The computer system of claim 16, wherein the metadata identifies currently active A/B tests, inactive A/B tests and associated treatments.

21. The computer system of claim 16, wherein the metadata includes page-level and page-module-level debugging information.
