How To Make A Chrome Extension

Step 1: Set up your project

Create a new folder on your computer and give it a meaningful name.

Inside the folder, create the following files:

manifest.json: This file will serve as the manifest for your extension.

popup.html: This file will be the HTML file for your extension’s popup.

popup.js: This file will contain the JavaScript code for your extension’s popup.

style.css: This file will contain the CSS styles for your extension.

Step 2: Define the manifest The manifest.json file is the heart of your extension. It defines important details about your extension, such as its name, version, permissions, and more. Here’s a basic example of a manifest.json file:

"manifest_version": 2,
"name": "My Chrome Extension",
"version": "1.0",
"description": "Description of your extension",
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
"browser_action": {
"default_popup": "popup.html",
"default_icon": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
"permissions": ["activeTab"]

Make sure to replace “My Chrome Extension” with the desired name of your extension. You’ll also need to create the icon files (icon16.png, icon48.png, and icon128.png) with the corresponding dimensions.

Step 3: Build the popup The popup is the small window that appears when the user clicks on the extension’s icon. Open the popup.html file and add your desired HTML structure. Here’s an example:

<!DOCTYPE html>
  <title>My Chrome Extension</title>
  <link rel="stylesheet" type="text/css" href="style.css">
  <script src="popup.js"></script>
  <h1>Welcome to My Chrome Extension!</h1>
  <button id="myButton">Click Me</button>

Feel free to modify the HTML structure and content to fit your needs. Also, link the style.css file for custom styling and the popup.js file to add interactivity.

Step 4: Style your extension Open the style.css file and add CSS rules to style your extension’s popup. For example:

body {
  font-family: Arial, sans-serif;
  text-align: center;

h1 {
  color: #333;

button {
  padding: 10px 20px;
  background-color: #007bff;
  color: #fff;
  border: none;
  border-radius: 5px;
  cursor: pointer;

button:hover {
  background-color: #0056b3;

Customize the styles based on your preferences to make your extension visually appealing.

Step 5: Add functionality with JavaScript Open the popup.js file and write JavaScript code to add functionality to your extension’s popup. Here’s an example:

document.addEventListener('DOMContentLoaded', function() {
  var button = document.getElementById('myButton');
  button.addEventListener('click', function() {
    alert('Button clicked!');

In this example.

Step 1: Set up your project

Create a new folder on your computer for your extension project.

Inside the folder, create the necessary files for your extension, such as HTML, CSS, and JavaScript files.

Step 2: Create the manifest file

In the root folder of your project, create a file named manifest.json. This file serves as the configuration for your extension.

Open manifest.json in a text editor and define the required properties, such as "name", "version", and "manifest_version". Additionally, specify permissions and other optional properties based on your extension’s functionality. Refer to the Chrome extension documentation for a full list of available options and their usage.

Step 3: Build the extension’s functionality

Create or modify the necessary HTML, CSS, and JavaScript files to implement the desired functionality of your extension.

Use HTML to structure the user interface of your extension, CSS to style it, and JavaScript to add interactivity and logic.

Link your JavaScript and CSS files to your HTML file(s) using appropriate <script> and <link> tags.

Step 4: Test the extension locally

Open Google Chrome and navigate to chrome://extensions.

Enable Developer Mode by toggling the switch at the top-right corner of the page.

Click on “Load unpacked” and select the root folder of your extension project.

Your extension should appear in the list of installed extensions. Make sure to enable it if it’s not already enabled.

Test your extension’s functionality to ensure it behaves as expected.

Step 5: Package and distribute your extension (optional)

If you’re ready to distribute your extension, you can package it into a .crx file or publish it on the Chrome Web Store.

To package your extension, navigate to chrome://extensions, locate your extension, and click on “Pack extension”.

Follow the instructions and provide the necessary details to create the package.

Alternatively, you can publish your extension on the Chrome Web Store by following the guidelines and requirements provided by Google.

Remember to regularly test and update your extension as needed, and be mindful of the Chrome extension guidelines to ensure compliance and a positive user experience.
