Slim
A fast, lightweight Ruby template language that reduces HTML syntax to essential parts using indentation.
What is Slim?
Slim is a Ruby template language that simplifies HTML generation by using indentation-based syntax instead of closing tags. It reduces boilerplate code while ensuring well-formed HTML, with features like automatic escaping, embedded engines (e.g., Markdown), and high performance. Slim solves the problem of verbose and error-prone HTML templating by providing a clean, minimal syntax.
Ruby developers building web applications with Rails, Sinatra, or Rack who want cleaner, more maintainable HTML templates. It’s ideal for teams prioritizing readability, safety, and performance in their view layer.
Developers choose Slim for its elegant, minimal syntax that reduces typing and errors, its strong safety defaults with automatic HTML escaping, and its flexibility through plugins and embedded engines. It’s a drop-in replacement for ERB/HAML with comparable speed and broad framework support.
Overview
