Syncrow
Real time directory synchronization using sockets. It can be used as a command line tool, and as a library in other programs.
Currently in Beta
Installation
$ npm install -g syncrow
Configuration
You need to configure syncrow in directory that you want to synchronize.
$ syncrow init
This command will run an interactive setup,
similar to npm init
, it will ask questions and save your answers.
The result will be a .syncrow.json
with your setup.
Running
$ syncrow run
or just $ syncrow
This command will look for .syncrow.json
file in current directory,
if the file exists it will start a syncrow process using it as configuration.
Connecting two machines
First install syncrow globally on both machines that you want to connect. Setup one machine to listen for incoming connections: (Your password will be stored as a hash)
user@server $ syncrow init
? Do you want to listen for connection? Yes
? On which local port would you like to listen 2510
? What is your external IP/hostname? 192.168.0.6
? Please enter comma-separated anymatch patterns for files that should be ignored .git,node_modules
? What synchronization strategy for every new connection would you like to choose? No Action - existing files will be ignored, only new changes will be synced
? Please enter password for obtaining connection my_horse_is_amazing
? Would you like to setup advanced options? No
Then configure syncrow on second machine that will connect:
user@laptop $ syncrow init
? Do you want to listen for connection? No
? Connection: remote host 192.168.0.6
? Connection: remote port 2510
? Please enter comma-separated anymatch patterns for files that should be ignored .git,.idea,node_modules
? What synchronization strategy for every new connection would you like to choose? Push - when other party connects all remote files will be overwritten by those local
? Please enter password for obtaining connection my_horse_is_amazing
? Would you like to setup advanced options? No
Once configured - start syncrow on both machines:
user@server $ syncrow run
and
user@laptop $ syncrow run
After a connection is obtained syncrow will sync existing files. This will run both syncrow instances as a foreground processes. It is possible to connect multiple connecting syncrow instances to single syncrow listener
Using as a library
It is possible to use syncrow as a part of node program.
Class: Server
Listens for incoming connections.
new Server(params)
const syncrow = require('syncrow');
const server = new syncrow.Server({path: './path/to_watch', localPort: 2510, externalHost: '192.168.0.2'});
params:
path
String path to watchlocalPort
Number port to listen onexternalHost
String external domain/IP[initalToken]
String optional token that will be used for authentication[watch]
Boolean optional, defaults totrue
, if set tofalse
server will not watch local files
server.engine
An instance of syncrow.Engine
server.start(callback)
starts the server watching the FS and listening for connections.
server.shutdown()
Completely stops the server.
event: connection
Emitted when remote party connects to the server
Class: Client
Connects to remote server.
new Client(params)
const syncrow = require('syncrow');
const client = new syncrow.Client({path: './path/to_watch', remotePort: 2510, remoteHost: '127.0.0.1'});
params:
path
String path to watchremotePort
Number port for connectionremoteHost
String host for connection[initalToken]
String optional token that will be used for authentication[watch]
Boolean optional, defaults totrue
, if set tofalse
server will not watch local files
client.engine
An instance of syncrow.Engine
client.start(callback)
starts the watching the path and connects to remote server.
client.shutdown()
Disconnects and stops the client.
Class: Engine
Watches local file system and handles messages from remote parties. It should not be created directly.
const server = new syncrow.Server({path: './path/to_watch', localPort: 2510, externalHost: '192.168.0.2'});
server.start((err)=>{
if(err) return console.error(err);
server.engine.on('newFile', (file)=>console.log(`remote created a new file: ${file}`));
server.engine.on('changedFile', (file)=>console.log(`remote changed file: ${file}`));
server.engine.on('deletedPath', (path)=>console.log(`remote deleted path (file or directory): ${path}`));
});
event: newFile
emitted when file changed by remote has been downloaded. Params:
filePath
String
event: changedFile
emitted when file changed by remote has been downloaded. Params:
filePath
String path of the file that changed
event: deletedPath
emitted when path (file or directory) has been deleted locally. Params:
filePath
String path of the file/directory deleted
event: newDirectory
emitted when directory created by remote has been created locally. Params:
dirPath
String path of the directory created
event: error
emitted on error. Params:
error
Error
event: synced
emitted when synchronization with remote has finished
Major TODOS:
- Add interval synchronization
- Separate into several repositories
- Integrate with Atom
