Providing access to a hybrid application offline

Disclosed are systems, methods, and non-transitory computer-readable storage media for providing access to a hybrid web application offline. In some implementations, a computing device can be configured with a hybrid application that includes a native layer and a web view. The native layer can provide access to native features of the computing device while the web view can provide web client features, such as graphical user interfaces and server communication functionality. When the computing device is offline and the hybrid application is invoked, the native layer can load from local storage a resource bundle including the web code needed to present the web view graphical user interface, and/or facilitate communication with the web server. Similarly, when the computing device is offline, the hybrid application can load previously stored content items into the web view from local storage through the native layer so that the user can work with the content items offline.
