Using the HTML5 Filesystem API - A True Filesystem for the Browser - E-book - Multi-format

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
