PersistJS, a client-side JavaScript persistent storage library, has been released.

See some of the features or visit the project’s homepage.

• Small (9.3k minified, 3k gzipped)
• Standalone: Does not need any additional browser plugins or JavaScript libraries to work on the vast majority of current browsers.
• Consistent: Provides a consistent, opaque API, regardless of the browser.
• Extensible: Custom backends can be added easily.
• Backwards Compatible: Can fall back to flash or cookies if no client-side storage solution for the given browser is available.
• Forwards Compatible: Supports the upcoming versions of Internet Explorer, Firefox, and Safari (Opera too, if you have Flash).
• Unobtrusive: Capability testing rather than browser detection, so newer standards-compliant browsers will automatically be supported.
