Hugo Interview Questions and Answers for experienced

1. What is Hugo, and what are its key features?

   • Answer: Hugo is a fast, open-source static site generator written in Go. Key features include its blazing-fast build speed, support for various themes and layouts, extensive markdown support, built-in shortcodes, and a clean, organized directory structure. It's ideal for blogs, portfolios, and documentation websites.

2. Explain the difference between static site generators (SSGs) and dynamic website platforms like WordPress.

   • Answer: SSGs like Hugo generate entire websites as static HTML files, which are then served directly by a web server. This results in faster loading times and improved security. Dynamic platforms like WordPress generate content on the fly with every request, leading to potential performance bottlenecks and increased security vulnerabilities.

3. How does Hugo handle themes? Describe the process of creating and implementing a custom theme.

   • Answer: Hugo uses a directory structure to organize themes. Custom themes typically involve creating a new directory within the `themes` folder, containing layouts, partials, assets (CSS, JS, images), and a `theme.toml` configuration file. You then select the theme using the `theme` parameter in your site's `config.toml` file.

4. What are Hugo's built-in shortcodes, and how can you create custom shortcodes?

   • Answer: Hugo provides shortcodes for tasks like creating alerts, callouts, and more. Custom shortcodes are created by placing `.html` files within the `layouts/shortcodes` directory. These files define the HTML to be rendered when the shortcode is used in your content.

5. Explain the concept of layouts in Hugo and how they work.

   • Answer: Layouts define the overall structure and design of your website's pages. Hugo uses templates written in Go's template language to render content within a given layout. Layouts are organized hierarchically, allowing for inheritance and reusability.

6. How does Hugo handle content organization? Describe the role of different folder structures.
