# SMB2 Client for Node.js
[](http://badge.fury.io/js/smb2) [](https://david-dm.org/bchelli/node-smb2) [](https://codeclimate.com/github/bchelli/node-smb2)
## Introduction
This library is a simple implementation of SMB2 for Node.js. It allows you to access a SMB2 share as if you were using the native fs library.
The development is still at an experimental stage and should not be yet considered for production environment.
## Installation
```bash
npm install -S smb2
```
## API
### var smb2Client = new SMB2 ( options )
The SMB2 class is the constructor of your SMB2 client.
the parameter ```options``` accepts this list of attributes:
- ```share``` (mandatory): the share you want to access
- ```domain``` (mandatory): the domain of which the user is registred
- ```username``` (mandatory): the username of the user that access the share
- ```password``` (mandatory): the password
- ```port``` (optional): default ```445```, the port of the SMB server
- ```packetConcurrency``` (optional): default ```20```, the number of simulatanous packet when writting / reading data from the share
- ```autoCloseTimeout``` (optional): default ```10000```, the timeout in milliseconds before to close the SMB2 session and the socket, if setted to ```0``` the connection will never be closed unless you do it
Example:
```javascript
// load the library
var SMB2 = require('smb2');
// create an SMB2 instance
var smb2Client = new SMB2({
share:'\\\\000.000.000.000\\c$'
, domain:'DOMAIN'
, username:'username'
, password:'password!'
});
```
### smb2Client.readdir ( path, callback )
Asynchronous readdir(3). Reads the contents of a directory. The callback gets two arguments (err, files) where files is an array of the names of the files in the directory excluding '.' and '..'.
Example:
```javascript
smb2Client.readdir('Windows\\System32', function(err, files){
if(err) throw err;
console.log(files);
});
```
### smb2Client.readFile ( filename, [options], callback )
- ```filename``` String
- ```options``` Object
- ```encoding``` String | Null default = null
- ```callback``` Function
Asynchronously reads the entire contents of a file. Example:
```javascript
smb2Client.readFile('path\\to\\my\\file.txt', function(err, data){
if(err) throw err;
console.log(data);
});
```
The callback is passed two arguments (err, data), where data is the contents of the file.
If no encoding is specified, then the raw buffer is returned.
### smb2Client.writeFile ( filename, data, [options], callback )
- ```filename``` String
- ```data``` String | Buffer
- ```options``` Object
- ```encoding``` String | Null default = 'utf8'
- ```callback``` Function
Asynchronously writes data to a file, replacing the file if it already exists. data can be a string or a buffer.
The encoding option is ignored if data is a buffer. It defaults to 'utf8'.
Example:
```javascript
smb2Client.writeFile('path\\to\\my\\file.txt', 'Hello Node', function (err) {
if (err) throw err;
console.log('It\'s saved!');
});
```
### smb2Client.mkdir ( path, [mode], callback )
Asynchronous mkdir(2). No arguments other than a possible exception are given to the completion callback. mode defaults to 0777.
Example:
```javascript
smb2Client.mkdir('path\\to\\the\\folder', function (err) {
if (err) throw err;
console.log('Folder created!');
});
```
### smb2Client.rmdir ( path, callback )
Asynchronous rmdir(2). No arguments other than a possible exception are given to the completion callback.
Example:
```javascript
smb2Client.rmdir('path\\to\\the\\folder', function (err) {
if (err) throw err;
console.log('Folder deleted!');
});
```
### smb2Client.exists ( path, callback )
Test whether or not the given path exists by checking with the file system. Then call the callback argument with either true or false. Example:
```javascript
smb2Client.exists('path\\to\\my\\file.txt', function (err, exists) {
if (err) throw err;
console.log(exists ? "it's there" : "it's not there!");
});
```
### smb2Client.unlink ( path, callback )
Asynchronous unlink(2). No arguments other than a possible exception are given to the completion callback.
```javascript
smb2Client.unlink('path\\to\\my\\file.txt', function (err) {
if (err) throw err;
console.log("file has been deleted");
});
```
### smb2Client.rename ( oldPath, newPath, callback )
Asynchronous rename(2). No arguments other than a possible exception are given to the completion callback.
```javascript
smb2Client.rename('path\\to\\my\\file.txt', 'new\\path\\to\\my\\new-file-name.txt', function (err) {
if (err) throw err;
console.log("file has been renamed");
});
```
### smb2Client.close ( )
This function will close the open connection if opened, it will be called automatically after ```autoCloseTimeout``` ms of no SMB2 call on the server.
