Abstract

A server for editing content using a single page application (SPA). The server comprises a processor, a memory, and a self-contained SPA, that is configured to receive a request from a workstation to edit a selected segment within a file, wherein the file comprises a plurality of segments including the selected segment, determine if the selected segment is locked, wherein locked file segments are unavailable for editing, upon determining that the selected segment is unlocked, provide access to the selected segment to the workstation, lock the selected segment for a period of time, wherein the selected segment is unavailable for editing by any other workstations, receive a save request from the workstation to save changes made to the selected segment, save the changes made in the selected segment within the file, and unlock the selected segment, wherein the unlocked segment is available for editing by any workstation.

Claims

1. A method implemented in a server for editing content using a single page application, comprising:

receiving a request from a workstation to edit a selected segment of a plurality of segments within a file, wherein the file is in a markup language format, and wherein the plurality of segments within the file comprises source code in at least one of Cascading Style Sheets or JavaScript;

determining if the selected segment is locked, wherein any segments that are locked are unavailable for editing;

upon determining that the selected segment is unlocked, providing access to the selected segment to the workstation, wherein the selected segment is accessed by the single page application, and wherein the single page application is a self-contained application without links to external resources;

locking the selected segment for a period of time, wherein the selected segment is unavailable for editing by any other workstations;

receiving a save request from the workstation to save changes made to the selected segment;

saving the changes made in the selected segment within the file;

receiving a preview request from the workstation to preview the changes made to the selected segment within the file prior to publishing;

responsive to receiving the preview request and prior to publishing a new version of the file comprising the selected segment, sending predefined global sub-sections of the file and the selected segment to the workstation for previewing, wherein the previewing comprises combining the predefined global sub-sections and the source code in the selected segment to create a single markup language document that is rendered and displayed by a web browser in the workstation as the selected segment is to appear after publication;

subsequent to the previewing, publishing the new version of the file comprising the selected segment, wherein the new version of the file is in the markup language format and is self-contained without links to external resources outside of the new version of the file;

responsive to the publishing, sending, to a plurality of users with access to the file, a notification message indicating that the file has been updated and the new version of the file has been published; and

unlocking the selected segment, wherein the unlocked selected segment is available for editing by any workstation.

2. The method of claim 1, wherein the file is stored in a data store accessible by the single page application in the server.

3. The method of claim 1, further comprising:

upon determining that the selected segment is locked, sending a message to the workstation, wherein the message indicates that the selected segment is locked and unavailable for editing.

4. The method of claim 1, wherein providing access to the selected segment to the workstation further comprises sending content of the selected segment, a copy of the selected segment, or a link to the selected segment to the workstation.

5. The method of claim 4, wherein the content sent to the workstation is displayed via the web browser at the workstation and edited via an editor at the workstation.

6. The method of claim 1, further comprising:

upon expiration of the period of time, unlocking the selected segment;

receiving a lock request from the workstation to lock the selected segment for an additional period of time; and

locking the selected segment as requested, wherein the selected segment is unavailable for editing by any other workstation.

7. The method of claim 1, further comprising:

receiving a create request from the workstation to create a new segment in the file;

creating the new segment in the file; and

storing the new segment in the file in a data store.

8. The method of claim 1, wherein the period of time is initiated upon receiving a keystroke from the workstation.

15. The method of claim 1, wherein the notification message comprises a link to download or access the new version of the file in a data store.

16. The method of claim 15, wherein the notification message further indicates and describes the changes made in the selected segment in the new version of the file.

17. The method of claim 1, wherein the single markup language document is a HyperText Markup Language (HTML) document.

9. A server for editing content using a single page application, comprising:

a processor;

a memory; and

a single page application stored in the memory, wherein the single page application is a self-contained application without links to external resources, that when executed by the processor, is configured to;

receive an edit request from a workstation to edit a selected segment of a plurality of segments within a file, wherein the file is in a markup language format, and wherein the plurality of segments within the file comprises source code in at least one of Cascading Style Sheets or JavaScript;

determine if the selected segment is locked, wherein file segments that are locked are unavailable for editing;

upon determining that the selected segment is unlocked, provide access to the selected segment to the workstation;

lock the selected segment for a period of time, wherein the selected segment is unavailable for editing by any other workstations;

receive a save request from the workstation to save changes made to the selected segment;

save the changes made in the selected segment within the file;

receive a preview request from the workstation to preview the changes made to the selected segment within the file prior to publishing;

responsive to receiving the preview request and prior to publishing a new version of the file comprising the selected segment, send predefined global sub-sections of the file and the selected segment to the workstation for previewing, wherein the previewing comprises combining the predefined global sub-sections and the source code in the selected segment to create a single markup language document that is rendered and displayed by a web browser in the workstation as the selected segment is to appear after publication;

subsequent to the previewing, publish the new version of the file comprising the selected segment, wherein the new version of the file is in the markup language format and is self-contained without links to external resources outside of the new version of the file;

responsive to the publishing, send, to a plurality of users with access to the file, a notification message indicating that the file has been updated and the new version of the file has been published; and

unlock the selected segment, wherein the unlocked segment is available for editing by any workstation.

10. The server of claim 9, wherein the single page application further comprises an application in a collaborative environment that allows users associated with other workstations to create, edit, and view the file.

11. The server of claim 9, wherein the markup language format is a HyperText Markup Language (HTML) format.

12. The server of claim 9, wherein the workstation is one of a laptop, a desktop, a tablet, or a mobile device.

13. The server of claim 9, wherein the file is stored in a data store, and wherein the data store is located in the memory of the server.

14. The server of claim 9, wherein the period of time is initiated upon providing access to the selected segment to the workstation.
