At a glance

Inertia.js is a library that bridges backend frameworks (Laravel, Rails, Django) with front-end frameworks (React, Vue, Svelte). You write component logic in JavaScript but architecture remains a traditional monolith (single deploy). Mastery takes 3-4 weeks if you know Laravel/Rails + React/Vue. Senior Inertia developers earn 10-15% premium because Inertia adoption is growing (companies like Ping Pong, Tuple use it). It's uncommon because most teams choose either REST API + SPA or full-stack JavaScript (Next.js).

What is Inertia.js Monolith

Inertia.js is a framework that bridges traditional backend frameworks (Laravel, Rails, Django) with modern front-end frameworks (React, Vue, Svelte). Instead of building an API and a separate single-page app, you return data and a component name from your backend, and Inertia renders the corresponding front-end component. The result is a monolithic architecture (backend and frontend deployed together) with modern front-end UX. You keep the simplicity of traditional web development while leveraging React/Vue reactive components.

❓ FAQ

Why use Inertia.js instead of REST API + separate frontend?

REST API forces you to think in two languages (backend API, frontend). With Inertia, backend is the source of truth: Laravel controller returns data + component name. Frontend renders component with that data. No API spec to maintain. CRUD becomes 'controller sends data, component renders form, submit back to controller.' One mental model instead of two.

How does Inertia differ from Next.js?

Next.js is full-stack JavaScript with file-based routing, API routes, server components. Inertia is backend-driven: you use Laravel/Rails logic, Inertia handles rendering. Next.js is more powerful (streaming, ISR, edge), but Inertia is simpler if you already know Rails/Laravel. Pick Inertia if team knows backend framework; pick Next.js if you prefer JavaScript end-to-end.

Can I use Inertia for mobile apps?

Inertia is web-only. For mobile, use Expo/React Native (if starting fresh) or WebView + Inertia (wrap web app). Inertia's architecture (server-driven rendering) is less ideal for mobile offline support.

How do I handle API endpoints in Inertia?

Inertia is for page navigation and form submissions. If you need mobile endpoints or third-party API access, add JSON endpoints alongside Inertia routes. Example: GET /users (Inertia → component) and GET /api/users (JSON for mobile).

What about state management with Inertia?

Keep state in the backend where possible (database source of truth). Frontend state (form input, UI toggles) lives in React/Vue component state. Inertia's shared data (flash, auth) handled server-side. No Redux/Pinia needed unless you have complex client state.

Can I deploy Inertia to Vercel?

Not directly. Inertia is server-driven (Rails/Laravel host the app). You'd need a Node.js/Ruby/Python hosting (Heroku, Railway, Fly.io). Vercel is for Next.js (edge-friendly). Options: host on traditional server (cheap), or run Node.js API server + Inertia frontend (hybrid).
