Domain bus

Seamless communication between browser tabs/windows on the same domain.

• Works offline
• Uses localStorage to synchronize
• Inspired by page-bus
• See also browser-bus

Examples

var Bus = require('domain-bus');

var bus = new Bus();

bus.listen(function( message ){
    if (message === 'ping')
        bus.write('pong');

    console.log(message);
});

bus.write('ping');

Run the above script in a minimum of two tabs simultaneously.

Open example.html in multiple tabs to see a very basic chat functionality.

Interface

var bus = new Bus({
    // defaults
    env: window,
    namespace: '',
});

// write a message to the bus. Any JSON value is supported via JSON.stringify.
bus.write(message);

bus.listen(fn); // `fn(message)` will be called for each received message
