Rhales is a framework for building server-rendered components with client-side data hydration using .rue files called RSFCs (Ruby Single File Components). Similar to Vue.js single file components but for server-side Ruby applications. Features include Handlebars-style templating, JSON data injection, partial support, pluggable authentication adapters, and security-first design.
