An async wrapper to the rsync command line utility for Node.js. Also available as the Grunt task grunt-rsync.
0.4.3
Added theexcludeFirst
option. See #34.0.4.2
Add defaultchmod
arguments on Windows to fix NTFS permissions, see #28.0.4.1
RenamedsyncDest
andsyncDestIgnoreExcl
options to the more scary soundingdeleteAll
anddelete
options in an effort to avoid potential user data loss due to misconfiguration. Updated docs to use the new option names. The old option names will continue to work.0.4.0
Reworking the way stdin is passed from the process to the rsync child process to facilitate Windows clients being able to read a passphrase from stdin.0.3.0
Swapping include/exclude order in the generated rsync command. Includes now come before excludes to faciliate the normal way of excluding file patterns with exceptions in rsync. See #16.0.2.0
Now launching the rsync command in a shell likechild_process.exec
does in Node Core. This enables us to usespawn
, and avoidexec
maxBuffer
, while retaining full shell wildcard expansion.0.1.0
Now usingchild_process.exec
as opposed tochild_process.spawn
to enable proper shell wildcard expansions in theoptions.src
value. SSH option handling has been improved.0.0.1
Initial release.
A reasonably modern version of rsync (>=2.6.9) in your PATH.
$ npm install rsyncwrapper
var rsync = require("rsyncwrapper").rsync;
rsync(options,[callback]);
The callback
function gets four arguments (error,stdout,stderr,cmd)
.
error
: An Error
object if rsync failed, otherwise null
.
stdout
: stdout from rsync.
stderr
: stderr from rsync.
cmd
: The command string that was used to invoke rsync for debugging purposes.
The options
argument is an object literal. See below for possible fields.
Path to src. Can be a single filename, or an array of filenames. Shell wildcard expansion is supported. Examples:
src: "./dist/"
src: ["./dir-a/file1","./dir-b/file2"]
src: "./*.foo"
src: "foo{1,2,3}.txt"
etc.
Path to destination. Example, "/var/www/mysite.tld"
.
Run rsync over ssh. This is false
by default. To use this you need to have public/private key passwordless ssh access setup and working between your workstation and your host. If set to true
, you should specify ssh host data as part of your src
or dest
values, e.g. [email protected]:/var/www/site
.
Another good approach is to define a host alias in your ssh config and just reference that alias in your rsync options.
If your ssh host uses a non standard SSH port then set it here. Example, "1234"
.
To specify an SSH private key other than the default for this host. Example, "~/.ssh/aws.pem"
Recurse into directories. This is false
by default which means only files in the src
root are copied. Equivalent to the --recursive
rsync command line flag.
Take care with this option, since misconfiguration could cause data loss. Deletes objects in dest
that aren't present in src
, also deletes files in dest
that have been specifically excluded from transfer. Equivalent to setting both the --delete
and --delete-excluded
rsync flags.
Take care with this option, since misconfiguration could cause data loss. The same as deleteAll
, but without the --delete-excluded
behaviour. One use case for using this option could be while syncing a Node app to a server: you want to exclude transferring the local node_modules
folder while retaining the remote node_modules
folder.
By default files will be compared by modified date and file size. Set this value to checksum
to compare by a 128bit checksum, or sizeOnly
to compare only by file size.
Optional array of rsync patterns to include in the transfer, if previously excluded. Include patterns are defined before exclude patterns when building the rsync command.
Optional array of rsync patterns to exclude from transfer. Include patterns are defined before exclude patterns when building the rsync command.
Optional array of rsync patterns to exclude from transfer. These are defined before the include patterns when building the rsync command. This is useful to exclude specific files or folders that would be included by the include patterns.
Buffer verbose information to stdout about the actions rsyncwrapper would take without modifying the filesystem. Equivalent to setting both the --dry-run
and --verbose
rsync command line flags.
Optional callback function. Called every time rsync outputs to stdout
. Use this to print rsync output as it happens, rather than all at the end. Example: function (data) { console.log(data) }
.
Optional callback function. Called every time rsync outputs to stderr
. Use this to print rsync error output as it happens, rather than all at the end. Example: function (data) { console.log(data) }
.
Array of additional arbitrary rsync command line options and flags.
String of additional ssh command line arguments and options. You can use this to have more control over the ssh connection. See SSH's clients man page for more.
The above options are provided for convenience and are designed to cover the most common use cases for rsync, they don't necessarily map directly to single rsync arguments with the same names. If you'd like to handcraft your rsync command then just use the src
, dest
and args
options.
For extra information and subtlety relating to rsync options please consult the rsync manpages.
Basic tests are run on Vows Async BDD via this package's Gruntfile. To test rsyncwrapper clone the repo and ensure that the devDependancies are present. Additionally ensure that Grunt and Vows are installed globally, and then invoke:
$ npm test
Copy a single file to another location. If the dest
folder doesn't exist rsync will do a mkdir
and create it. However it will only mkdir
one missing directory deep (i.e. not the equivalent of mkdir -p
).
rsync({
src: "file.txt",
dest: "tmp/file.txt"
},function (error,stdout,stderr,cmd) {
if ( error ) {
// failed
console.log(error.message);
} else {
// success
}
});
Copy the contents of a directory to another folder, while excluding txt
files. Note the trailing /
on the src
folder and the absence of a trailing /
on the dest
folder - this is the required format when copying the contents of a folder. Again rsync will only mkdir
one level deep:
rsync({
src: "src-folder/",
dest: "dest-folder",
recursive: true,
exclude: ["*.txt"]
},function (error,stdout,stderr,cmd) {
if ( error ) {
// failed
console.log(error.message);
} else {
// success
}
});
Syncronise the contents of a directory on a remote host with the contents of a local directory. The deleteAll
option will delete all files on the remote host that either aren't present in the local folder or have been excluded from transfer.
rsync({
src: "local-src/",
dest: "[email protected]:/var/www/remote-dest",
ssh: true,
recursive: true,
deleteAll: true // Careful, this could cause data loss
},function (error,stdout,stderr,cmd) {
if ( error ) {
// failed
console.log(error.message);
} else {
// success
}
});
- Add tests to cover usage of more options.
