HTML Gamepad API: Introduction

Over the years, gaming has advanced dramatically, moving from straightforward console games to lifelike virtual reality experiences. The growth of online technology has made game production more accessible than ever. The foundation of the web, HTML, has its own set of APIs that let programmers build interactive browser-based experiences.

The HTML Gamepad API is one such API that provides gamepad functionality in online applications. This beginner’s tutorial will teach you how to design games to play with game controllers and introduce you to the HTML Gamepad API.

Understanding the HTML Gamepad API

A standardized method of interacting with gamepads and controllers linked to a user’s device is provided via the HTML Gamepad API. JavaScript enables gamepad devices like Xbox controllers and PlayStation DualShock controllers to be accessed and used as input devices. By employing this API, game developers may give players a flawless gaming experience in their online apps.

Checking Browser Support

Confirming that the target browser supports the HTML Gamepad API before utilizing it is crucial. Although the majority of contemporary browsers support the API, it’s a good idea to double-check. To determine whether the browser is compatible with the Gamepad API, use the following bit of code:

if ("getGamepads" in navigator) {
// Gamepad API is supported
} else {
// Gamepad API is not supported

browser support

Accessing Gamepad Data

You must use the navigator to retrieve the gamepad data. An array of gamepad objects representing the connected controllers is returned by the getGamepads() function. Information about the controller, including its ID, buttons, and axes, is provided by each gamepad object.

An illustration of how to get gamepad data is shown below:

window.addEventListener("gamepadconnected", (event) => {
const gamepad = event.gamepad;
console.log("Gamepad connected:",;
window.addEventListener("gamepaddisconnected", (event) => {
const gamepad = event.gamepad;
console.log("Gamepad disconnected:",;

Handling Gamepad Input

After accessing the gamepad data, you can control the input to create interactive gaming. Check for changes in the variety of buttons and Axis on each gamepad. Axes give continuous input data, while you can use buttons to push or release.

An example of how to handle axis and button input is  here:

function handleGamepadInput() {
const gamepads = navigator.getGamepads();
for (const gamepad of gamepads) {
if (gamepad) {
for (const button of gamepad.buttons) {
if (button.pressed) {
// Button is pressed
} else {
// Button is released
for (const axis of gamepad.axes) {
if (axis > 0.5) {
//Axis is moved to the positive direction
} else if (axis < -0.5) {
//Axis is moved to the negative direction
}  } } }
// Update gamepad input every frame
function update() {
// Start the game loop

Creating a Game with Gamepad Support

Let’s make a basic game that users can play with a gamepad now that you know how to access and manage gamepad input. To illustrate this tutorial, we will make a straightforward platformer game.

<!DOCTYPE html>
<title>Gamepad Platformer</title>
/* CSS styles for the game */
// JavaScript code for the game

You may handle gamepad input and modify the game state using the HTML Gamepad API in the JavaScript section. You may respond to axis input to manage leaping or other actions and listen for button pushes to control the player character’s motions.

Enhancing the Gamepad Experience

Using the Gamepad API, you may add elements like haptic feedback and controller vibration to enhance the gaming experience. These improvements might improve the gameplay and increase immersion.

The navigator.vibrate() function allows you to make compatible controllers vibrate.

if ("vibrate" in navigator) {
navigator.vibrate(100); // Vibrate for 100 milliseconds

Gamepad Tester and Debugger

Testing your game throughout development on various gamepad and browser combinations is essential to ensure compatibility. Additionally, you can examine the gamepad data with the help of browser development tools, keep an eye on the button and axis states, and spot any potential problems.

The HTML Gamepad API: What is it?

A JavaScript API called the HTML Gamepad API enables developers to communicate with gamepads and controllers attached to a user's device. Developers may design games with gamepad support in web apps because it offers a standardized way to access and receive input from multiple gamepad devices.

What is a gamepad tester?

A gamepad tester is a device or piece of software that enables you to test and evaluate your controller's or gamepad's performance. It gives visual feedback and shows the input from the controller's buttons, axes, and other functions to verify that the controller functions correctly.

Can a controller test be performed using the HTML Gamepad API?

Yes, you can use a controller tester with the HTML Gamepad API. You may build your controller testing feature within your web application by accessing the gamepad data and watching the input from buttons and axes.

How can I use the HTML Gamepad API to verify controller input?

You may use the HTML Gamepad API to gain access to the gamepad data and track the input from buttons and axes to run a controller input test. You may test and confirm the controller's functioning by recording and showing the input values.

How can I test a controller in my online application using the HTML Gamepad API?

Designate a testing area within your web application where you can access and display the gamepad data to test a controller using the HTML Gamepad API. You can check if the controller works as it should by observing the input from the buttons and Axis.

Can the HTML Gamepad API be utilized to test joysticks?

Yes, a joystick tester may be used with the HTML Gamepad API. Since joysticks are frequently included in gamepad controllers, you can efficiently test their functioning by accessing the gamepad data and watching the joystick's input axis.

Do any tools for testing gamepads or controllers already exist?

Yes, there are a variety of online gamepad and controller tester tools. These tools let you evaluate input from buttons, axes, and other features while giving visual feedback, which may help you assess your gamepad's or controller's operation. You may find a variety of alternatives online by searching for 'gamepad tester' or 'controller tester.'


The HTML Gamepad API expands the options for developing controller-compatible web games. By implementing this API, developers may give customers a recognizable gaming experience using their preferred gamepads and controllers.

In this article, we went through the fundamentals of the HTML Gamepad API, including how to access gamepad data, how to handle input, how to make games that support gamepads, how to improve the user experience with haptic feedback, and how to test and debug programs. With this information, you may create games to play in the browser using gaming controllers. Have fun playing!
