Using the HTML5 Filesystem API (Paperback)

Several client-side storage options are available to web applications, but one area that's been lacking until now is file I/O—the ability to organize binary data into a true hierarchy of folders. That has changed with the advent of HTML5. With this book, you'll learn how to provide your applications with a file system that enables them to create, read, and write files and folders in a sandboxed section of the user's local filesystem.

Author Eric Bidelman, a Senior Developer Programs Engineer on the Google Chrome team, provides several techniques and complete code examples for working with the HTML5 Filesystem API.

• Learn common operations for working with files and directories
• Become familiar with HTML5's storage use cases and security considerations
• Understand the storage options available, including temporary, persistent, and unlimited
• Write text or append data to an existing user file
• Import files into your application by accessing a user's hard drive
• Get techniques for using a file with filesystem, blob, or data URLs
• Use the synchronous version of the HTML5 Filesystem API within a Web Worker context
