Framework to facilitate taking snapshots of web application on demand

A system comprising:

• a microprocessor;
• and
• a non-transient computer-readable storage medium, comprising computer instructions executable by the microprocessor, wherein the computer instructions are configured to perform a method comprising the steps of:
• capturing user data and corresponding user interface state information from a current page of a web application after the current page was loaded on a client computer, wherein
• the capturing is performed by a process executing on the client computer, wherein
• the capturing is performed by the process in response to detecting either a change being made to the user data or in response to detecting a change with respect to a state of the user interface,
• the capturing is performed after the current page was loaded and prior to submitting the user data or the corresponding user interface state information to a server, and
• the capturing results in captured user data and captured corresponding user interface state information;
• storing the captured user data and the captured corresponding user interface state information in a persistent memory on the client computer;
• receiving a command to restore the web application to a previous state;
• subsequent to receiving the command to restore the web application to the previous state, displaying a list of one or more available snapshot versions;
• subsequent to displaying the list to a user, receiving a selection of a snapshot version;
• determining a selected version of captured user data and corresponding user state information to use in restoring the web application to the previous state, wherein
• the selected version of the captured user data and corresponding user state information is determined based, at least in part, on the selection of the snapshot version;
• and
• subsequent to determining the selected version of the captured user data and the captured corresponding user state information to use in restoring the web application to the previous state, restoring the web application to the previous state by using the selected version of the captured user data and the captured corresponding user interface state information to restore the user data and the user interface state information in the current page of the web application.

A computer program product, comprising a plurality of instructions stored on a non-transient computer-readable storage medium, wherein the instructions are configured to execute a method comprising the steps of:

• capturing user data and corresponding user interface state information from a current page of a web application after the current page was loaded on a client computer, wherein
• the capturing is performed by a process executing on the client computer, wherein
• the capturing is performed by the process in response to detecting either a change being made to the user data or in response to detecting a change with respect to a state of the user interface,
• the capturing is performed after the current page was loaded and prior to submitting the user data or the corresponding user interface state information to a server, and
• the capturing results in captured user data and captured corresponding user interface state information;
• storing the captured user data and the captured corresponding user interface state information in a persistent memory on the client computer;
• receiving a command to restore the web application to a previous state;
• subsequent to receiving the command to restore the web application to the previous state, displaying a list of one or more available snapshot versions;
• subsequent to displaying the list to a user, receiving a selection of a snapshot version;
• determining a selected version of captured user data and corresponding user state information to use in restoring the web application to a previous state, wherein
• the selected version of the captured user data and corresponding user state information is determined based, at least in part, on the selection of the snapshot version;
• and
• subsequent to determining the selected version of the captured user data and the captured corresponding user state information to use in restoring the web application to a previous state, restoring the web application to the previous state by using the selected version of the captured user data and the captured corresponding user interface state information to restore the user data and the user interface state information in the current page of the web application.
