Chrome Extension Development

This course takes learners from basic HTML, CSS, and JavaScript knowledge to building and deploying a functional Chrome Extension.

Module 1: The Basics of Chrome Extension Architecture

Topic	Key Concepts & Activities
Introduction & Setup	What Extensions are, use cases, and the development environment (VS Code, Chrome Developer Mode).
Manifest V3 Fundamentals	The `manifest.json` file: `manifest_version: 3`, name, version, and icons. Loading an “unpacked” extension in Chrome.
The Action API & Popup UI	Defining the browser action (the icon in the toolbar). Creating the `default_popup` HTML and CSS.
Project 1	Build a “Hello World” Popup Extension with a button that changes the popup’s text color.

Module 2: Core Components and Interactivity

Topic	Key Concepts & Activities
Content Scripts	How to inject scripts into a web page’s DOM. Declaring a content script in `manifest.json`. Accessing and modifying a live webpage (e.g., changing background color).
Background Service Workers	The core logic component in MV3. Understanding Service Workers as event listeners that are non-persistent. Registering the worker in `manifest.json`.
Permissions and Security	Understanding the security model. Requesting `permissions` (e.g., `storage`, `activeTab`) and `host_permissions` in the manifest.
Project 2	Build a “Tab Highlighter” Extension that injects a Content Script to outline all images on a page when the popup button is clicked.

Module 3: Data, Communication, and Events

Topic	Key Concepts & Activities
Message Passing	Essential for communication! Sending messages from Content Scripts to the Service Worker and vice-versa (one-time requests and long-lived connections).
Storage API	Using `chrome.storage.local` (persistent, non-synced data) and `chrome.storage.sync` (data synced across browsers). Saving and retrieving user preferences.
Listening to Browser Events	Using the Service Worker to listen for common events (e.g., `chrome.tabs.onUpdated`, `chrome.windows.onCreated`).
Debugging	Using the Chrome DevTools for the Popup, Service Worker, and Content Script console logs and inspection.
Project 3	Build a “Reading List Saver” that lets the user save the current tab’s URL and title to `chrome.storage` via the popup, then displays the list in an HTML options page.

Module 4: Advanced Features and Deployment

Topic	Key Concepts & Activities
External Communication	Making API requests (e.g., using `fetch`) from the Service Worker and handling responses.
Advanced UI (Options Page)	Creating a dedicated Options Page (`options_page` in manifest) for more complex settings and configuration.
The Declarative Net Request API	Introduction to the MV3 method for blocking or modifying network requests without full access to request data (a security-focused replacement for `webRequest`).
Publishing to the Chrome Web Store	Creating screenshots and descriptions. The submission process and compliance with Developer Program Policies.
Final Project	Build a complete, publishable extension (e.g., a simple Productivity Timer/To-Do List or a Custom Ad-Blocker concept).
