rsync-slim

rsync-slim

Slim wrapper around rsync.
Use rsync options as on the command line.

Prerequisites

rsync needs to be installed on your machine. Or cwRsync on Windows.

Installation

npm install rsync-slim --save-dev

Usage

Basic:

var rsync = require('rsync-slim');

rsync({
  src: ['index.html', 'css', 'img'],
  dest: '[e-mail]:/path/on/server',
  options: '-rtvhcz --delete --progress'
});

In a gulp task:

var rsync = require('rsync-slim');

gulp.task('deploy', function() {
  var secrets = require('./secrets.json');

  rsync({
    src: 'build',
    dest: secrets.rsync.dest,
    options: '-rtvhcz --delete --progress',
    ssh: 'authFile',
    log: require('gulp-util').log
  });
});

with a file secrets.json like:

{
  "rsync": { "dest": "[e-mail]:/path/on/server" }
}

which you can keep private by adding a line secrets.json to the file .gitignore.

Variations:

rsync({
  ....
  log: true,   // Will use console.log for logging.
  sync: false  // Launches rsync in async process; script doesn't wait.
},
  function(err) {  // Custom callback function.
    console.log(err);
  }
);

API

rsync(settings, callback) :

• settings :

  • src (Array|String), required :
    an array or space-separated string of source files and folders.

  • dest (String), required :
    the destination server+path.

  • options (Object) :
    the raw rsync-command options.

  • log (Boolean|Function) :
    If true, the generated rsync-command will be sent to console.log.
    If it is a function, then it will be called with this command as String argument.

  • sync (Boolean), default=true :
    Tells whether to launch rsync synchronously (true) and wait for it to finish,
    or in an asynchronous process (false).

  • stdio (String|Array), default='inherit' :
    The child process's input/output configuration. Is passed on as stdio option to child_process.spawn/spawnSync.

  • ssh (String), default='' :
    If not empty then an option -e "ssh -i <sshAuthFile>" is generated.
    If only a filename without path, then the user's home folder + '/.ssh' is prepended (works on Window and *nix).
    On Windows, paths like C:\Users\x\.ssh\sshAuthFile are converted to cwRsync-compatible cygwin filepaths, e.g. /cygdrive/c/Users/x/.ssh/sshAuthFile.

• callback(err) :

  is called when rsync finishes. err is null on success, else an Error object.

  If no callback is given and rsync finishes with an error, then an Error object is thrown instead.

Tips

• For Windows clients using cwRsync:

  Create a batch-file rsync.bat that sets cwRsync's required environment-variables, and put it in a location included in your PATH:

  @echo off
  setlocal
  set RSYNC_HOME=%PROGRAMFILES%\cwRsync
  set HOME=%USERPROFILE%
  set PATH=%RSYNC_HOME%;%PATH%
  rsync %*
  

• cwRsync accepts absolute paths like /cygdrive/c/path/to/source instead of C:\path\to\source.
