About the Quarto Favorites Extension

This extension adds a simple but powerful feature to Quarto websites: the ability for users to bookmark or “favorite” pages for easy access later.

Why Create This Extension?

When browsing large documentation sites or complex websites, users often need to return to specific pages repeatedly. The Favorites extension provides a way for users to create their own personalized collection of important pages.

How It Works

The extension uses the browser’s localStorage to store the user’s favorites. This means:

• Favorites persist even after the browser is closed
• No server-side processing is required
• The solution works with static Quarto websites
• Each user’s favorites are stored on their own device

Technical Implementation

The extension consists of:

• Lua filters that inject JavaScript, CSS, and HTML into pages
• Client-side JavaScript for managing favorites
• CSS for styling the favorites button and list

Since Quarto generates static websites, all favorites functionality runs entirely in the user’s browser.
