We are excited to announce the open source release on GitHub of the offline-persistence-toolkit for JavaScript client applications, developed by the Oracle JavaScript Extension Toolkit (Oracle JET) team.

The Offline Persistence Toolkit is a client-side JavaScript library that provides caching and offline support at the HTTP request layer. This support is transparent to the user and is done through the Fetch API and an XHR adapter. HTTP requests made while the client device is offline are captured for replay when connection to the server is restored. Additional capabilities include a persistent storage layer, synchronization manager, binary data support and various configuration APIs for customizing the default behavior.

Whilst the toolkit is primarily intended for hybrid mobile applications created using Oracle JET, it can be used within any JavaScript client application that requires persistent storage and/or offline data access.

The Offline Persistence Toolkit simplifies life for application developers by providing a response caching solution that works well across modern browsers and web views. The toolkit covers common caching cases with a minimal amount of application-specific coding, but provides flexibility to cover non-trivial cases as well. In addition to providing the ability to cache complete response payloads, the toolkit supports "shredding" of REST response payloads into objects that can be stored, queried and updated on the client while offline.

The architecture diagram illustrates the major components of the toolkit and how an application interacts with it: Read the complete article here.
