Why I Built This

I wanted to explore Chrome extension development while creating something fun and useful. This project helped me:

• Learn the fundamentals of Chrome extension architecture
• Understand manifest configuration and permissions
• Practice working with external APIs
• Create a delightful user experience with minimal resources
• Spread some joy and laughter during work breaks

Tech Stack

• HTML5 - Popup structure and content
• CSS3 - Styling and layout
• JavaScript - Joke fetching logic and DOM manipulation
• Chrome Extension API - Browser integration and popup management
• icanhazdadjoke API - Source of dad jokes

How It Works

Extension Setup

When installed, Chrome loads the extension based on the manifest.json configuration, which defines the extension's name, version, permissions, icons, and popup HTML file.

User Interaction

When the user clicks the extension icon in the Chrome toolbar, the browser opens the popup window defined in popup.html, which contains the UI for displaying jokes.

Fetching Jokes

The script.js file runs automatically when the popup opens, making a fetch request to the icanhazdadjoke.com API with the proper headers to request JSON format.

Displaying Jokes

Once the API responds, the joke is extracted from the JSON response and displayed in the popup UI using DOM manipulation, with smooth animations for better UX.

Error Handling

If the API request fails due to network issues or API downtime, the extension displays a friendly error message and allows users to try again.
