Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Node.js xinput wrapper. Access xinput based controllers

xinput.js wraps the xinput game controller API. Besides allowing raw access to the xinput device, it also provides a small wrapper class which emits events based on controller input.

Contents

Requirements

xinput is only available on Windows. Please ensure you have the required dependencies as well as Visual Studio installed.

Building

node-gyp is required to build xinput.js.

Install node-gyp using npm:

npm install -g node-gyp

Then configure and build:

node-gyp configure
node-gyp build

Examples

Simple

var xinput = require('../');

[0, 1, 2, 3]
.filter(n => xinput.IsConnected(n))
.map(n => xinput.WrapController(n, {
	interval: 20,
	deadzone: {
		x: 0.20,
		y: 0.15
	},
	holdtime: 500
}))
.forEach(gamepad => {
	var n = gamepad.deviceNumber;

	gamepad.addListener("button-long", (button, elapsed) => {
		console.log("[%d] Hold button %s for %dms", n, button, elapsed);
		/* After holding the button for a while ->
		[1] Button buttons.a changed: true
		[1] Hold button buttons.a for 501ms
		[1] Button buttons.a changed: false
		*/
	});

	gamepad.addListener("button-short", (button, elapsed) => {
		console.log("[%d] Pressed button %s for %dms", n, button, elapsed);
		/* After tapping the button for a short moment ->
		[1] Button control.start changed: true
		[1] Button control.start changed: false
		[1] Pressed button control.start for 101ms
		*/
	});

	gamepad.addListener("button-changed", (button, state) => {
		console.log("[%d] Button %s changed: %s", n, button, state);
		/* Find example output in both listeners above */
	});

	gamepad.addListener("analog-input", (input, data) => {
		console.log("[%d] Holding %s at:", n, input, data);
		/* Moving the left stick to the left ->
		[1] Holding leftstick at: { x: -0.04042176580095827, y: 0 }

		[1] Holding leftstick at: { x: -1, y: 0 }
		*/

		/* Holding both triggers for a short moment ->

		*/
	});

	gamepad.addListener("connection-changed", (isConnected) => {
		console.log("[%d] Connection state changed: %s", n, isConnected ? "Connected!" : "Disconnected!");
		/* Pulling out the batteries + plugging them back in ->
		[1] Connection state changed: Disconnected!

});

Raw

var xinput = require('../');

// Test all controllers 0-3
[0, 1, 2, 3].forEach(controllerNum => {
	console.log("Controller %d connected:", controllerNum, xinput.IsConnected(controllerNum));
	// -> Connected: true

	if(xinput.IsConnected(controllerNum)) {
		// Dump the current state
		console.log("Controller %d state:", controllerNum, xinput.GetState(controllerNum));
		/* -> {
		  // Digital inputs
		  buttons: { a: false, b: false, x: false, y: false },
		  dpad: { left: false, right: false, up: false, down: false },

		  thumb: { left: false, right: false },
		  control: { back: false, start: false },

		  // Analog inputs
		  trigger: { left: 0, right: 0 },
		  leftstick: { x: -1679, y: 1514 },
		  rightstick: { x: -296, y: -3893 }
		} */

		// Vibrate and stop after 1s
		xinput.Vibrate(controllerNum, 0.5, 0.5);
		setTimeout(() => xinput.Vibrate(controllerNum, 0.0, 0.0), 1000);
	}
