Using the HTML5 Filesystem API

A True Filesystem for the Browser

• Broschiertes Buch

Produktbeschreibung

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
