ExtPlaneJs

A JavaScript Client Library for NodeJs that uses the ExtPlane plugin.

Inspired by ExtPlaneInterface for Java and ExtPlaneNet for C#

Prerequisites

1. You need X-Plane (demo works fine) with the ExtPlane plugin installed.
2. NodeJs >= 4.0.0

Installation

Install via NPM

$ npm install extplanejs

Connecting to X-Plane

Make sure X-Plane is started and the plugin is installed and active.

ExtPlaneJs Config

Either modify the config.json or modify the config object passed into ExtPlaneJs

{
    "host": "127.0.0.1",
    "port": 51000,
    "broadcast": false,
    "debug": true
}

Running the example connector

1. Open your terminal
2. cd to ExtPlaneJs
3. Install Node.js Dependencies npm install
4. Run npm start

Watch your terminal as your X-Plane information is streamed on-screen

Running the tests

1. Make sure X-Plane is running and in a current flight. Not on the QuickFlight screen.
2. Run npm test

Example

var ExtPlaneJs = require('extplanejs');

var ExtPlane = new ExtPlaneJs({
    host: '127.0.0.1',
    port: 51000,
    broadcast: true
});

ExtPlane.on('loaded', function(){

    ExtPlane.client.interval(0.33);

    // Subscribe to the airspeed
    ExtPlane.client.subscribe('sim/cockpit2/gauges/indicators/airspeed_kts_pilot');

    // Handle all data-ref changes
    ExtPlane.on('data-ref', function(data_ref, value){
        console.log(data_ref+' - '+value);
    });

});
