ws-chan

WebSocket interaction modeled as a pair of streams, for incoming and outgoing messages correspondingly. It provides:

  • JSON encoding/decoding of incoming/outgoing messages correspondingly
  • reconnect logic with exponential backoff (by default)

Example usage

On a client:

var channel = require('ws-chan');
var ch = channel('ws://localhost');

ch.in.on('data', function(message) {
  console.log('received', message);
});
ch.out.write({'data': 1});

Channel also emits open, end and error events on corresponding socket stream events.

On socket end and error channel tries to re-establish a connection after some timeout which is handled by node-backoff module (by default exponential backoff algorithm is used).
