• Use Buffer (No encoding problem, binaries easy)
• AMD (CommonJS, RequireJS, etc)
• Works with Cordova/Phonegap/ionic

Dependencies

• Buffer: https://github.com/anodynos/node2web_buffer
• Async.js: https://github.com/caolan/async
• eventemitter2 https://github.com/hij1nx/EventEmitter2

Instalation

$ bower install cofs

Usage

var fs = new CoFS();

fs.readFile($('input[type="file"]').files[0], function (err, data) {

    if (err) {

    }

    console.log("Data of file:" + data.toString('utf-8'));

});

API

CoFS (Object)

new CoFS([options]);

CoFS object is a Class, options parameter is optional:

var fs = new CoFS();

Options can be:

• fs: Type of FileSystem request, by Default is PERSISTENT (see this page)
• logger: Callback for debug logger

CoFS.noConflict()

Returns CoFS object and restore the var CoFS to back definition.

~CoFS (Instance)

~CoFs.on(eventName, callback)

Subcribe callback to event.

~CoFS.once(eventname, callback)

Like on, but the callback only runs once time.

~CoFS.getFileSystem([options], callback)

Get a FileSystem instance.

Options can be:

• fs: Type of filesystem, by default is PERSISTENT

~CoFS.getDirectory(dirName, [options], callback)

Get DirectoryEntry, the options are passed to the natie API, see this article.

~CoFS.getFileEntry(fileName, [options], callback)

Get a FileEntry instance, from a path

The options are pass to the native API, but accept a root param for define a directory, for example:

var fs = new CoFS();

fs.getDirectory('data', function (err, directory) {

    // ...

    fs.getFileEntry('myFile.dat', { root: directory }, function (err, file) {
        //...
    });
});

~CoFS.readFromFileObject(file, callback)

Read a file from a native File instance.

~CoFS.readFromFileEntry(fileEntry, callback)

Read a file from a native FileEntry object.

~CoFS.readFile(file, callback)

Identify the object passed and read a file, the first param cab be a File object, FileEntry object, or a String with the file path.

~CoFS.writeFile(fileName, data, [encoding], callback)

Write a file with the content of data, if data is a Buffer object, encoding is not expected, is data is a String, encoding is needed.
