Static website generators (SSGs) are programs that create HTML pages of a website from text-based template files or already prepared HTML sources. A SSG represent an alternative to a database-based system (CMS) such as WordPress. In content management systems, the content of a website is not managed in simple text files but stored in (relational) databases such as MySQL.

A typical CMS-driven website works by building each and every page dynamically. That means fetching the content from a database to pass them over to a template system (engine) to load the page content, adding the required structure information (e.g., CSS styles) and Javascript components if needed. This means every page is assembled on demand.

A Static Site Generator takes a different approach and generates all the pages of the website upfront. That does not necessarily mean that a static website is always built from scratch. Modern generators support a so-called incremental build, as does. When there are changes detected to the content, only selected pages will rebuild.

In the case of blogs, documentation sites, or company websites, CMS and website builders are used for this, but static site generators have distinct advantages over a typically much more complex content management solution:

Jekyll is a popular Static Site Generator (SSG). As the name SSG implies, the generator component creates websites, but Jekyll is not a content management system (CMS) like WordPress. A static site generator is a perfect toolset to create and manage personal, project, or documentation sites because they do not rapidly change their content.

The generator concept dispenses with the convenience of a website editing system using centralized stored content in databases, in favor of editing simple files with the help of text editors. SSGs like Jekyll read the code of a content page from simple text files that contain rendering information already.

The makers of Jekyll describe it this way:

An SSG creates websites based on static content sources and generates web pages that a web server can directly deliver. A CMS creates dynamic content pages that require a web server and a rendering system to present web pages to the users. The outcome of an SSG like Jekyll and a CMS like WordPress may be quite the same, but the required software and infrastructure are very different in terms of complexity.

To install and run Jekyll, the dynamic programming language Ruby is required. Jekyll is a Ruby Gem that is supported on all current Windows, Linux and MacOS systems.

Run the command gem below in a terminal to install Jekyll:

The Ruby Gem of Jekyll contains a commandline interface (CLI) and a library system to extentend and customize the builder engine.

To use Jekyll, it is needed to learn the basics of the static websites development. The builder engine is a commandline interface (CLI) and no Graphical User Interface (GUI) or Web Interface (UI) managed by a web browser is provided.

The latest version of Jekyll v4.3.1 is issued in October 2022 and version v4.4.0 is being prepared for 2023. The next version of Jeykyll V5 is under construction and a tentative roadmap is discussed at Github: Jekyll v5 Roadmap

Jekyll is a static site generator (SSG), not a content management system (CMS) in the traditional sense.

A CMS is a software application that allows users to create, manage, and publish digital content on the web, often providing features such as content creation, editing, media management, user management, and more. Examples of popular CMS platforms include WordPress, Drupal, and Joomla.

On the other hand, Jekyll is a static site generator that takes plain text files written in markup languages like Markdown or HTML and generates static HTML files that a web server can serve. Jekyll allows you to create websites or blogs with a predefined structure and layout. It does not require a database or server-side processing, as it generates static files that can be hosted on any web server or content delivery network (CDN).

While Jekyll provides powerful features for building static websites and blogs, it does not have the dynamic content management capabilities typically associated with CMS platforms, such as user authentication, content editing interfaces, and database-driven content management. However, Jekyll can be combined with other tools or services to add dynamic functionality to static websites, such as client-side JavaScript, APIs, or third-party services.

Jekyll and WordPress are different tools with different use cases, and their performance can vary depending on various factors. Jekyll is generally known for generating static HTML files, which can offer faster page load times than dynamic CMS platforms like WordPress, which dynamically generate HTML pages on the fly.

Jekyll generates static HTML files during the build process, and these files are served as-is to visitors when they request a page. Static content results in faster page load times because no server-side processing is required to generate the HTML on the fly. Additionally, web servers or content delivery networks (CDNs) can easily cache static HTML files, improving performance.

On the other hand, WordPress is a dynamic CMS that uses a server-side scripting language (such as PHP) and a database to generate HTML pages on the fly when a visitor requests a page. CMS introduces additional server-side processing overhead, database queries, and potentially slower page load times, especially for complex websites with large amounts of dynamic content.

However, it’s important to note that performance is affected by various factors, including server configuration, caching, content optimization, and more. Both Jekyll and WordPress can be optimized for performance, and the actual performance of a website built with either tool will depend on how it is implemented, hosted, and configured.

In general, if performance is a top priority and you have a relatively simple website with static content, Jekyll may offer faster page load times than WordPress. However, if you require complex dynamic functionality, frequent content updates, or extensive user management, WordPress or another CMS with dynamic capabilities may be more suitable. Ultimately, the choice between Jekyll and WordPress should be based on your specific needs, technical expertise, and performance requirements.

No, Jekyll is not a framework but a static site generator (SSG).

A framework is a pre-prepared library or set of tools that provides a structure or set of conventions for building web applications or websites. Frameworks typically include predefined libraries, modules, or templates that developers can use to build applications or websites more efficiently, often following specific patterns or best practices.

On the other hand, Jekyll is a static site generator that takes plain text files written in markup languages like Markdown or HTML and generates static HTML files that a web server can serve. Jekyll allows you to create websites or blogs with a predefined structure and layout, but it does not provide dynamic functionality or server-side processing like a framework. Jekyll is primarily used for creating static websites or blogs that do not require server-side processing or databases. It generates static files that can be hosted on any web server or content delivery network (CDN).

While Jekyll provides a structure and a set of conventions for building static websites or blogs, it is not a framework in the traditional sense, as it does not provide dynamic functionality, server-side processing, or libraries for building web applications. However, Jekyll can be combined with other tools or services, such as JavaScript, APIs, or third-party services, to add dynamic functionality to static websites.

No, Jekyll is not a programming language. Jekyll is a static site generator (SSG) built using the Ruby programming language. However, Jekyll itself is not a programming language.

Jekyll uses markup languages like Markdown or HTML and a template language called Liquid to generate static HTML files that a web server can serve. Markup languages like Markdown or HTML are used to define web pages' content and structure. At the same time, Liquid is a template language that allows you to add dynamic content, conditional logic, and other features to your Jekyll templates.

On the other hand, Ruby is a general-purpose, object-oriented programming language used to build applications and tools, including Jekyll. Jekyll is a Ruby application that leverages the power of Ruby to generate static websites from plain text files written in markup languages.

While Jekyll involves scripting using Liquid for defining templates, it is not a standalone programming language. Jekyll is a tool that uses Ruby and other markup languages to generate static websites but does not have a programming language.

Yes. Jekyll is a static site generator built using the Ruby programming language. Ruby is a general-purpose, object-oriented programming language known for its simplicity and flexibility. Jekyll is a Ruby-based tool that allows users to create static websites or blogs by processing plain text files written in markup languages like Markdown or HTML and generating static HTML files that a web server can serve.

Jekyll uses Ruby to power its templating system, allowing users to define their website’s structure, layout, and behavior using templates. Jekyll also leverages Ruby’s powerful features, such as its file handling capabilities, to process input files, apply templates, and generate output files during the build process.

While Jekyll is built on Ruby, it is important to note that users need to be more proficient in Ruby to use Jekyll. Jekyll provides a higher-level abstraction through its Liquid template language, which allows users to define templates using a simple syntax separate from Ruby. However, users with Ruby knowledge can use Jekyll’s extensibility features to create custom plugins or modify their behavior using Ruby code.

Yes, Jekyll is a Ruby gem. Ruby gems are packages or libraries written in the Ruby programming language that can be easily installed and used in Ruby applications or projects. Jekyll is a gem that provides a static site generator (SSG) for creating static websites or blogs.

To use Jekyll, you typically need to install Ruby and RubyGems (the Ruby package manager) on your system. Once you have Ruby and RubyGems installed, you can install Jekyll as a gem using the following command:

This command will install Jekyll as a gem on your system, making it available for use in your Ruby applications or projects. After installation, you can use Jekyll to create, configure, and build static websites or blogs from plain text files written in markup languages like Markdown or HTML. Jekyll provides a set of conventions and templates for building static websites, and it can be customized using its configuration files and plugin system.

No, Jekyll is not built on or dependent on Ruby on Rails (often just referred to as Rails), a web application framework written in the Ruby programming language. Jekyll is a separate tool not directly related to Ruby on Rails.

While both Jekyll and Ruby on Rails are written in Ruby and used for building websites, they serve different purposes and use cases. Jekyll is a static site generator (SSG) that generates static HTML files from plain text files written in markup languages like Markdown or HTML. It is typically used for creating static websites or blogs without dynamic server-side processing or databases. Jekyll generates static files that can be hosted on any web server or content delivery network (CDN).

On the other hand, Ruby on Rails is a full-stack web application framework that follows the model-view-controller (MVC) architectural pattern. Rails provides a set of conventions and tools for building dynamic, database-driven web applications with server-side processing. Rails includes features like an ORM (Object-Relational Mapping) for database interactions, a templating system for rendering views, and a routing system for handling HTTP requests.

While both Jekyll and Ruby on Rails are written in Ruby, they serve different purposes and are used in different contexts. Jekyll is typically used for static websites or blogs, while Ruby on Rails is used for dynamic web applications with server-side processing. They are not directly related to each other and do not have dependencies on each other.

While Jekyll is built using Ruby, and some advanced customization or plugin development in Jekyll may require Ruby knowledge, it is unnecessary to have a deep understanding of Ruby to use Jekyll effectively. Jekyll provides a higher-level abstraction through its template language, Liquid, which allows users to define templates using a simple and separate syntax that does not require extensive Ruby knowledge.

Jekyll primarily aims to generate static websites or blogs from plain text files written in markup languages like Markdown or HTML. Users can create, configure, and build static websites with Jekyll by following its conventions and using its built-in features without needing to write Ruby code.

However, having a basic understanding of Ruby can be helpful for customizing Jekyll templates, creating custom plugins, or making advanced configurations. For example, if you want to create a custom layout or modify the behavior of a Jekyll theme, you may need to use some Ruby code. But even in such cases, you can typically find examples or documentation that provide the necessary Ruby code snippets or configurations without becoming a Ruby expert.

In summary, while knowledge of Ruby can be beneficial for advanced customization or plugin development in Jekyll, it is optional for basic usage of Jekyll to create static websites or blogs. Jekyll provides a higher-level abstraction through its template language, Liquid, which allows users to define templates without extensive Ruby knowledge.

Yes, Jekyll uses Markdown as one of the markup languages to create content for static websites or blogs. Markdown is a lightweight markup language widely used for creating formatted text documents that are easy to read and write. Jekyll supports Markdown as one of its primary markup languages, along with HTML, to create content for web pages.

With Jekyll, users can write content in Markdown files, which are plain text files with a specific syntax that allows easy text formatting and simple markup. Jekyll then processes these Markdown files during the build process and converts them into static HTML files that a web server can serve.

Markdown is a popular choice for content creation in Jekyll because of its simplicity, readability, and compatibility with other tools and platforms. Markdown allows users to write content in a simple, human-readable format converted into HTML by Jekyll during the build process. Mardown makes it easy for users to create formatted content for their Jekyll-powered websites or blogs without needing to write raw HTML code.

Yes, Jekyll supports AsciiDoc as one of the markup languages for creating content. AsciiDoc is a lightweight markup language designed for creating technical documentation, providing more advanced formatting options than Markdown.

With Jekyll, users can write content in AsciiDoc, plain text files with a specific syntax that allows easy text formatting with markup. Jekyll then processes these AsciiDoc files during the build process and converts them into static HTML files that a web server can serve.

AsciiDoc provides a richer feature set than Markdown, including support for tables, diagrams, footnotes, cross-references, and more. It also allows for more fine-grained control over the output formatting, making it suitable for more complex documentation requirements. Jekyll supports AsciiDoc as an alternative to Markdown, allowing users to choose the markup language that best fits their content creation needs.

Yes, you can use HTML with Jekyll. Jekyll supports HTML as one of its primary markup languages for creating content. While Jekyll is known for its support of Markdown and AsciiDoc, it also allows you to include raw HTML code directly in your Jekyll templates or content files.

Using HTML means writing HTML code directly in your Jekyll templates, layouts, or includes, just like in a regular HTML file. Jekyll will process this HTML code during the build process and generate static HTML files that a web server can serve.

Using HTML directly in your Jekyll templates or content files can be useful in scenarios where you need more fine-grained control over the output HTML or when you want to include custom HTML elements, JavaScript, or other HTML-related functionality in your Jekyll-powered website or blog.

It’s worth noting that while Jekyll allows you to use HTML, it also provides higher-level abstraction through its built-in template language, Liquid, which makes it easier to create dynamic content and layouts without needing to write raw HTML code. However, if you are familiar with HTML and prefer to use it directly in your Jekyll templates or content files, you have the flexibility to do so.

Yes, you can use CSS with Jekyll. Jekyll is a static site generator that generates static HTML files, which can be styled using CSS like any other HTML web page.

When building a Jekyll-powered website or blog, you can create custom CSS files to define the styles for your site. Using the standard HTML <link> element in your Jekyll templates or layouts, you can include CSS files in your Jekyll project. For example, you can create a CSS file called style.css and include it in your Jekyll template like so:

In this example, the style.css file is assumed to be located in the /assets/css/ directory relative to the root of your Jekyll project. You can also use CSS frameworks or libraries in combination with Jekyll to enhance the styling of your site. Include the CSS files of the desired framework or library in your Jekyll templates or layouts, just like any other CSS file.

Jekyll does not have built-in CSS generation or processing capabilities as it does with Markdown or AsciiDoc for content. CSS files in Jekyll are static files that are copied as-is to the output directory during the build process, and their content is not processed or transformed by Jekyll. Therefore, you have full control over your CSS and can use any CSS code or techniques compatible with static HTML web pages.

Yes, you can use JavaScript with Jekyll. Jekyll is a static site generator that generates static HTML files. You can include JavaScript in you Jekyll-powered website or blog to add interactivity and dynamic functionality to your site.

There are several ways you can use JavaScript with Jekyll:

In this example, the script.js file is assumed to be located in the folder /assets/js/ relative to the root of your Jekyll project. You can also use JavaScript frameworks or libraries in combination with Jekyll to add more complex functionality to your site. Include the JavaScript files of the desired framework or library in your Jekyll templates or layouts, just like you would with any other JavaScript file.

Jekyll does not have built-in JavaScript generation or processing capabilities like it does with Markdown or AsciiDoc for content. JavaScript files in Jekyll are static files that are copied as-is to the output directory during the build process, and their content is not processed or transformed by Jekyll. Therefore, you have full control over your JavaScript code and can use any JavaScript techniques or libraries compatible with static HTML web pages.

Yes, you can use Bootstrap with Jekyll. Bootstrap is a popular CSS framework that provides pre-designed UI components and styles for building responsive web pages. Jekyll is a static site generator that generates static HTML files. You can use Bootstrap’s CSS and JavaScript files in your Jekyll-powered website or blog to enhance the styling and functionality of your site.

Here’s how you can use Bootstrap with Jekyll:

By using Bootstrap with Jekyll, you can easily leverage Bootstrap’s responsive design and pre-designed UI components to create modern and visually appealing websites or blogs with Jekyll.
