xplanejs is a Node.js module for data transfer to/from X-Plane. It currently supports reads only via UDP.

A simple example can be found in the examples/ folder. Either access the stored data directly or listen for events.

var XPlane = require('xplane')
  , xplane = new XPlane({
    port: {
      in: 49000 // default port for X-Plane UDP data
    }
  });
xplane.on('data.airspeed', function(speeds) {
  console.log('IAS: ' + speeds.indicated + ' kts');
});
xplane.listen();

// somewhere else:
console.log(xplane.data.airspeed);

To recieve data, you will need to set up X-Plane to send it. Head over to https://github.com/dmolin/flightSimPanels#architecture for instructions.

XTypes are defined in data/xtypes.js. They can be accessed on-demand from XPlane.data.[xtype.name], or by listening to the data.[xtype.name] event.

Would you like to contribute? Here's a couple of things the project needs a hand with:

• Adding xType definitions to data/xtypes.js
• Support for writing back to the sim via UDP
• DataRef access via the official SDK
