Rabl Rails

Overview

rabl-rails is a ruby templating system for rendering objects in different formats such as JSON, XML, and PLIST. It aims to be fast and have a small memory footprint while providing an intuitive DSL for building complex responses. This gem is designed for Rails 4.2/5/6 applications and has been tested with both MRI and jRuby.

Features

• Flexible Response Building: rabl-rails allows you to build responses using views, similar to how you would use HTML/erb/haml.
• Template Compilation: The gem separates template compilation (transforming a RABL-rails template into a Ruby hash) from the actual rendering of the object or collection. This allows for compiling the template only once (when template caching is enabled), resulting in improved performance.
• Access to Instance Variables: While compiling the template outside of any rendering context restricts access to instance variables, you can use symbols to represent variables, which the gem will retrieve when needed.
• Dynamic Code: The gem allows for the use of dynamic code within node or condition blocks, which is evaluated at each rendering.
• Supports Multiple Formats: rabl-rails supports formats such as JSON, XML, and PLIST, providing flexibility in the output format.
• Custom Configuration: The gem works out of the box with default options and the fastest engine available. However, you can configure global options and customize the output to match your needs.

Summary

rabl-rails is a powerful ruby templating system for rendering objects in various formats. It provides features such as flexible response building, template compilation, access to instance variables, support for dynamic code, and customizable configuration. With its intuitive DSL and support for popular formats like JSON and XML, rabl-rails offers developers a convenient way to build complex responses in Rails applications.
