FuseJS/FileSystem Module (JS)

Provides an interface to the file system.

var FileSystem = require("FuseJS/FileSystem");

Using the asynchronous Promise based functions is recommended to keep your UI responsive, although synchronous variants are also available if preferred.

When saving files private to the application you can use the dataDirectory property as a base path.

Example

This example writes a text to a file, and then reads it back:

var FileSystem = require("FuseJS/FileSystem");
var path = FileSystem.dataDirectory + "/" + "testfile.tmp";

FileSystem.writeTextToFile(path, "hello world")
    .then(function() {
        return FileSystem.readTextFromFile(path);
    })
    .then(function(text) {
        console.log("The read file content was: " + text);
    })
    .catch(function(error) {
        console.log("Unable to read file due to error:" + error);
    });
