node-webkit-winreg

node module that provides access to the Windows Registry through the REG commandline tool within node-webkit applications Based on Paul Bottin's winreg and includes George Petrov's fix for Windows XP

Installation

npm install node-webkit-winreg 

Usage

Let's start with an example. The code below lists the autostart programs of the current user.

var Winreg = require('winreg')
,   regKey = new Winreg({
      hive: Winreg.HKCU,                                          // HKEY_CURRENT_USER
      key:  '\\Software\\Microsoft\\Windows\\CurrentVersion\\Run' // key containing autostart programs
    })

// list autostart programs
regKey.values(function (err, items) {
  if (err)
    console.log('ERROR: '+err);
  else
    for (var i in items)
      console.log('ITEM: '+items[i].name+'\t'+items[i].type+'\t'+items[i].value);
});

The following options are processed by the Winreg constructor:

• host the optional hostname, must start with the '\\' sequence
• hive the optional hive id (see below), the default is HKLM
• key the optional key, the default is th root key

The key, if specified, has to start, but must not be terminated with a '\' character.

The instances of Winreg provide access to a single registry key. The hive id can be one of the following:

• HKLM HKEY_LOCAL_MACHINE
• HKCU HKEY_CURRENT_USER
• HKCR HKEY_CLASSES_ROOT
• HKCC HKEY_CURRENT_CONFIG
• HKU HKEY_USERS

Registry values are returned as objects, containing the following information:

• host the hostname, if it has been set in the options
• hive the hive id, as specified in the options
• key the key, as specified in the options
• name the name of the registry value
• type one of the types listed below
• value a string containing the value

Registry values can have one of the following types:

• REG_SZ a string value
• REG_MULTI_SZ a multiline string value
• REG_EXPAND_SZ an expandable string value
• REG_DWORD a double word value (32 bit integer)
• REG_QWORD a quad word value (64 bit integer)
• REG_BINARY a binary value
• REG_NONE a value of unknown type

Following methods are provided by instances of Winreg:
