I’m excited to announce ExInertia, a toolkit built on top of Igniter that provides a robust integration between Phoenix and Inertia.js, with first-class support for Routes library and Bun.

Technical Stack:

• Built on Igniter for powerful, composable installer generators
• Full Inertia.js integration with Phoenix using Inertiajs/inertia-phoenix
• Modern asset pipeline using Bun + Vite (replacing esbuild/tailwind)
• Built-in Routes integration for type-safe routing between Phoenix and TypeScript
• Automated manifest handling for Vite assets

Installation:

def deps do
  [
    {:exinertia, "~> 0.5.0"},
  ]
end

The installer, powered by Igniter (thanks @zachdaniel ), handles the complete setup:

mix exinertia.install

What gets installed:

1. Vite manifest reader in your Web namespace
2. Inertia pipeline + configuration in your Router
3. Routes integration for type-safe routing
4. Modified root layout with Vite asset handling
5. Complete Bun + Vite setup replacing esbuild/tailwind
6. TypeScript-ready frontend structure with Routes type definitions
7. Automated mix aliases for asset building

Development Experience:

• Hot Module Replacement (HMR) with Vite
• TypeScript compilation with Bun
• Type-safe routing between Phoenix and TypeScript using Routes
• Seamless server-side rendering support
• Zero-configuration Tailwind integration

Type-safe routing example with Routes:

// Your routes are automatically typed!
const url = Routes.path('user.show', { id: 123 });
// => "/users/123"

// TypeScript error if you miss required params
const url = Routes.path('user.show'); // Error: missing id parameter

The project is built to be modular - you can use the installers independently or compose them with your own Igniter-based installers.

Contributions and feedback are welcome! We’re particularly interested in hearing about different use cases and integration patterns.
