Exploring Inertia.js: The Modern Monolith for JavaScript Apps

In an ever-evolving landscape of web development, new technologies and frameworks continuously emerge to simplify and optimize the process of building web applications. One such innovation that has caught the attention of developers is Inertia.js, which introduces a fresh approach to crafting classic server-driven web applications. Often referred to as the “modern monolith,” Inertia.js offers a unique blend of simplicity and power, enabling developers to create fully client-side rendered, single-page applications without the complexity associated with modern single-page applications (SPAs).

Understanding Inertia.js

Inertia.js, as described on its official website, is a game-changing approach to building web applications. It bridges the gap between server-driven web applications and client-side rendering, striking a balance that combines the best of both worlds.

The Modern Monolith

The central philosophy of Inertia.js revolves around crafting what it calls the “modern monolith.” In this context, a monolith refers to a traditional server-driven application where the server generates HTML and serves it to the client, a method that has been tried and tested for years. Inertia.js modernizes this approach by enabling fully client-side rendering while retaining the familiarity and simplicity of server-side patterns.

This means that you can build single-page applications with Inertia.js without the need for complex client-side routing or APIs. Instead, you can continue to create controllers and page views, much like you have always done, while benefiting from the advantages of client-side rendering.

Key Features of Inertia.js

Here are some of the key features that set Inertia.js apart:

1. No Client-Side Routing

Traditional SPAs often involve intricate client-side routing systems. Inertia.js simplifies this by eliminating the need for client-side routing altogether. You can navigate through your application without worrying about setting up and managing client-side routes, making development more straightforward.

2. No API Required

Another significant advantage of Inertia.js is that it doesn’t require an API to function. Instead, it leverages existing server-side patterns and communicates with your backend in a seamless manner. This approach reduces the complexity and overhead typically associated with managing API endpoints.

3. Backend Framework Agnostic

Inertia.js is designed to work seamlessly with various backend frameworks. While it is well-suited for Laravel, it’s not limited to it. Whether you are using Laravel, Rails, or any other backend framework, you can integrate Inertia.js into your project without hassle.

4. Adapters for Seamless Integration

Inertia.js isn’t a framework itself; rather, it serves as a bridge between your existing server-side and client-side frameworks. It accomplishes this through adapters. Currently, there are three official client-side adapters (React, Vue, and Svelte) and two server-side adapters (Laravel and Rails). These adapters make it easy to integrate Inertia.js into your tech stack, allowing you to benefit from its features without completely overhauling your existing architecture.

Getting Started with Inertia.js

If you’re intrigued by Inertia.js and want to give it a try, you can start by visiting the official documentation on the Inertia.js website. The documentation provides detailed information on installation, usage, and examples for various frontend frameworks and backend platforms.


Inertia.js presents a compelling approach to building web applications, striking a balance between the familiarity of server-driven web apps and the advantages of client-side rendering. By eliminating the need for client-side routing and APIs, it simplifies development while ensuring that your applications remain efficient and performant. Whether you’re a seasoned developer or just getting started, Inertia.js is definitely worth exploring as a valuable addition to your web development toolkit.
