Inertia.js
Inertia.js is a framework that allows developers to build single-page applications (SPAs) using server-side routing and controllers, without writing client-side API endpoints. It works by sending server-rendered pages as JSON responses to the client, where they are rendered using client-side frameworks like React, Vue, or Svelte. This approach combines the simplicity of traditional server-driven applications with the interactivity of modern SPAs.
Developers should use Inertia.js when they want to build SPAs with a server-side backend (e.g., Laravel, Rails, Django) without the complexity of managing separate API endpoints and client-side routing. It's ideal for projects where you prefer server-side logic and data handling but still need a responsive, dynamic frontend, such as admin panels, dashboards, or internal tools. It reduces boilerplate code and simplifies state management by leveraging server-side sessions and controllers.
