Extensionator - Rise of the Chromium
#1about 2 minutes

Understanding the core components of a Chrome extension

Chrome extensions are built from components like background scripts for events, content scripts for page modification, and UI elements for user interaction.

#2about 3 minutes

Creating the initial manifest.json for your extension

Every Chrome extension starts with a mandatory manifest.json file that requires three key fields: name, version, and manifest_version.

#3about 2 minutes

Customizing your extension with an icon and description

Enhance your extension's presentation in the management page by adding `icons` and a `description` to the manifest.json file.

#4about 5 minutes

Building a focus extension to redirect distracting websites

Use a background script with the `chrome.webRequest` API to intercept and redirect navigation from specified URLs to a more productive page.

#5about 3 minutes

Requesting API permissions and debugging your extension

To use powerful Chrome APIs like `webRequest`, you must declare them in the `permissions` field of your manifest and use the management page to inspect errors.

#6about 4 minutes

Building a reminder extension for work-life balance

A second extension example demonstrates how to create a tool that reminds you to stop working after a set amount of time to improve work-life balance.

#7about 5 minutes

Creating a popup UI using a browser action

Add an interactive popup to your extension by defining a `browser_action` in the manifest that points to an HTML file for the UI.

#8about 3 minutes

Setting and canceling timers with the Alarms API

Use JavaScript in your popup to interact with the `chrome.alarms` API, allowing users to create and cancel timed events.

#9about 6 minutes

Triggering system notifications from a background script

Listen for alarm events in a background script and use the `chrome.notifications` API to display a system notification to the user.

#10about 2 minutes

Final steps for publishing to the Chrome Web Store
