The HTML5 Filesystem API is a versatile API that addresses many of the uses cases that the other offline APIs don’t. It can remedy their shortcomings, like making it difficult to dynamically caching a page. I’m looking at you AppCache!
My ♥ for the API is deep—so much so that I wrote a book and released a library called filer.js to help promote its adoption. While filer aims to make the API more consumable, it fails to address the elephant in the room: browser support.
Today, I’m happy to bring the HTML5 Filesystem API to more browsers by releasing idb.filesystem.js.
I’ve thrown together two demo apps to demonstrate the library’s usage. The first is a basic example. It allows you to create empty files/folders, drag files into the app from the desktop, and navigate into a folder or preview a file by clicking its name:Try the demo in Firefox 11+
Want to use filer.js’s API with idb.filesystem.js? No problem. 90% of filer.js works out of the box with idb.filesystem.js. In fact, the second demo is a slightly modified version of filer.js’s playground app, showing that the two libraries can work in harmony. \m/
What’s exciting is that both of these apps work in FF, Chrome, and presumably other browsers that implement storing binary data in IndexedDB.
I look forward to your feedback and pull requests!
