## What it is
The Rails adapter for Inertia.js, letting you build single-page React, Vue, or Svelte apps on top of existing Rails controllers, routes, and authentication without a separate API. Controllers pass data as props via `render inertia:`, and client-side navigation is handled through XHR visits.

## Use cases
- build a react spa with rails backend without an api
- add vue or svelte frontend to existing rails app
- replace rails views with modern javascript components
- avoid building a separate rest or graphql api
- server-side render inertia pages in rails
- pass rails controller data as props to frontend

## When to choose
- you have a Rails app and want a modern SPA frontend without maintaining a separate API
- you want to reuse Rails controllers, routing, and authentication for client-side rendering
- you prefer a monolithic stack over a decoupled frontend/backend architecture

## When to avoid
- you need a standalone API consumed by native mobile apps or third parties
- your team prefers a fully decoupled SPA with a dedicated API backend
- you are not using Ruby on Rails
