You can install plugin to your Cordova project with command line:

cordova plugin add cz.blocshop.socketsforcordova

Usage is simple, you just have to create instance of socket object:

var socket = new Socket();

Then you need to setup data consumer, error and close handlers:

socket.onData = function(data) { // invoked after new batch of data is received (typed array of bytes Uint8Array) }; socket.onError = function(errorMessage) { // invoked after error occurs during connection }; socket.onClose = function(hasError) { // invoked after connection close };

Finally you can connect to server:

socket.open( "someremoteserver.com", 1234, function() { // invoked after successful opening of socket }, function(errorMessage) { // invoked after unsuccessful opening of socket });

At this point, socket instance is in connected state and you started to receive events to handlers you setup above.
Write method of the socket accepts only Uint8Array, so you have to convert your string data. This code shows how to do it:

var dataString = "Hello world"; var data = new Uint8Array(dataString.length); for (var i = 0; i

There are 2 options of how to close the connection.

1) You can close the connection gracefully by sending FIN packet using shutdownWrite method:

socket.shutdownWrite();

After you call this method, you should wait until server sends all data to you and closes the connection. After that, you receive socket.onClose event.

2) Second options is to close socket immediately:

socket.close();

You receive socket.onClose event shortly after you call this method. Writing data to closed socket is not allowed.
