This module provides Twig filters to easily transform strings into various common casing formats like camelCase, kebab-case, and snake_case. It's useful for theme development and frontend coding, helping you quickly format strings for class names and other conventions directly within your Twig templates.
Have you ever been in Twig and thought: "I just want a filter to make my string camelCase, kebab-case, MACRO_CASE, PascalCase, snake_case, or Train-Case?"
This module allows you to pass any string with spaces, dashes, underscores, or even messy input with special characters, and it will normalise and case your string correctly.
This module is designed for Drupal 10+ and is ideal for theme developers, frontend engineers, and anyone needing quick case transformations in their templates.
