node-gamepad

node-gamepad is a package for node that allows you to effortlessly interface your node applications with a variety of gamepad controllers.

Installation

npm install node-gamepad

Supported Controllers

snes/tomee
snes/retrolink
ps3/dualshock3
ps4/dualshock4
n64/retrolink
logitech/rumblepad2
logitech/dualaction
logitech/gamepadf710
microsoft/sidewinder-precision-2

How to Use

Plug in a supported controller and run a variation of the code below (with an actual supported controller):

Code Example

var GamePad = require( 'node-gamepad' );
var controller = new GamePad( 'supported/controller/here' );
controller.connect();

controller.on( 'up:press', function() {
    console.log( 'up' );
} );
controller.on( 'down:press', function() {
    console.log( 'down' );
} );

If you want to use the same configuration for another controller but the vendorID and/or productID is different that the one included in the existing controller dictionary, you can simply pass in an optional second parameter when instantiating the new GamePad object:

var GamePad = require( 'node-gamepad' );
var controller = new GamePad( 'supported/controller', {
	vendorID: 1337,
	productID: 1338
} );
controller.connect();

Both vendorID and productID are individually optional key/value pairs you can specify. If they are defined, they will override the ones in the controller's dictionary file, thus allowing you to use the same mapping but with a different product and/or vendor ID.

If you want to be implicit, you can drop the product ID from the controller type specification and node-gamepad will try to automatically detect the proper controller:

var GamePad = require( 'node-gamepad' );
var controller = new GamePad( 'snes' );

Please note: it's better to be explicit and specify the exact product ID so you don't run into any confusion with the configuration that's loaded.

Supported Events

This package supports up to 3 different types of components: joysticks, buttons and statuses (like battery level, charging, etc). It's possible that a controller could make use of all 3 different components or even introduce additional components. The idea here is the dictionary file will dictate how the controller will be used and how to read data from it.

Joysticks

{name}:move - When fired, this joystick event will provide an object literal with an x and y value.

Buttons

{name}:press - No data is attached to this callback but it serves the purpose of notifying the developer that a button has been pressed.
{name}:release - No data is attached to this callback but it serves the purpose of notifying the developer that a button (that was previously pressed) has been released.

Statuses

A status value is read from a pin on the hardware and then can be mapped to a "state" (based on the dictionary file). See this example for more information.

{name}:change

Contributing Controllers

You can add controller configuration files to the controllers directory. They are namespaced by platform/vendor.json. Each configuration file contains the pins/values mapped to the name of each button, joystick or status. You can use the hid-mapper tool which will help you create all the necessary mappings to save to your configuration file.
