Annotation Several client-side storage options are available to web applications, but one area that's been lacking until now is file I/Othe 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 directoriesBecome familiar with HTML5's storage use cases and security considerationsUnderstand the storage options available, including temporary, persistent, and unlimitedWrite text or append data to an existing user fileImport files into your application by accessing a user's hard driveGet techniques for using a file with filesystem, blob, or data URLsUse the synchronous version of the HTML5 Filesystem API within a Web Worker context. |
