Methods for updating applications

A storage medium including program instructions executable by one or more processors that, when executed, cause the one or more processors to perform operations, the operations comprising:

• transmitting, from a computing device to one or more server computers, an update request corresponding to a client-side application package that is stored at the computing device, the client side application package contains a plurality of application components;
• receiving a differential update package in response to the request, the differential update package including a plurality of deltas, wherein each delta corresponds to one of the application components contained in the client side application package;
• and
• applying the plurality of deltas to modify at least some of the application components from the plurality of application components.

An apparatus, comprising:

• one or more processors;
• and
• one or more memory devices for storing program instructions used by the one or more processors, wherein the program instructions, when executed by the one or more processors, cause the one or more processors to:
• transmit, from a computing device to one or more server computers, an update request corresponding to a client-side application package that is stored at the computing device, the client side application package contains a plurality of application components;
• receive a differential update package in response to the request, the differential update package including a plurality of deltas, wherein each delta corresponds to one of the application components contained in the client side application package;
• and
• apply the plurality of deltas to modify at least some of the application components from the plurality of application components.
