fs-sandbox

A wrapper around the node fs module, used in the Beaker Browser to give sandboxed access to files and folders.

Usage

var fs = require('fs')
var fss = require('fs-sandbox')
 
// create a folder sandboxed to `path`
var folder = fss.createFolderSandbox(path)
 
// api:
// (all *Sync variants are supported)
folder.appendFile(path, data[, options], callback)
folder.exists(path, callback)
folder.mkdir(path, callback)
folder.open(path[, flags], callback)
folder.readdir(path[, options], callback)
folder.readFile(path[, options], callback)
folder.rename(oldPath, newPath, callback)
folder.rmdir(path, callback)
folder.stat(path, callback)
folder.unlink(path, callback)
folder.writeFile(file, data[, options], callback)
 
// open a file sandboxed to a path
var file = fss.createFileSandbox(path + '/myfile.txt', fs.openSync(path + '/myfile.txt', 'w+'))
// or...
var file = folder.openSync('./myfile.txt', 'w+')
 
// api:
// (all *Sync variants are supported)
file.appendFile(data[, options], callback)
file.close(cb)
file.read(buffer, offset, length, position, callback)
file.readFile([options,] callback)
file.stat(cb)
file.sync(cb)
file.truncate(len, cb)
file.unlink(cb)
file.write(buffer, offset, length[, position], callback)
file.write(data[, position[, encoding]], callback)
file.writeFile(data[, options], callback)
