inertia-rails-auth

Authentication in an Inertia Rails application is implemented by integrating Devise or has_secure_password for login flows, then wiring session management through inertia_share in ApplicationController to expose current_user state to Vue or React components.

Sharing frontend permissions and current user state with Inertia components requires standardizing inertia_share calls in your Rails controllers to securely pass signed_in status and Pundit or Action Policy authorization data to the frontend.

Pundit and Action Policy both work for authorization in an Inertia Rails app, allowing you to enforce per-user permissions on Rails controllers and apply corresponding role-based access controls and guards within your Vue or React components.

Handling CSRF protection and secure routes with Inertia Rails involves configuring Rails to ensure CSRF tokens are properly shared and validated, while applying protected route restrictions for admin areas and authentication scopes across the stack.

Setting up Devise login and registration scaffolding for an Inertia frontend requires generating authentication controllers in Rails, wiring inertia shares, and implementing ready-made protected pages and password reset flows in your Vue or React components.
