jengo/inertia
jengo/inertia is the official CodeIgniter 4 adapter for Inertia.js.
Inertia allows you to create fully client-side rendered, single-page apps (SPAs) without much of the complexity that comes with modern SPAs. It does this by leveraging existing server-side routing and controllers.

Core Concept
Instead of returning a CodeIgniter View (view('welcome')), you return an Inertia response. Inertia intercepts this on the client side and dynamically swaps the page component without reloading the browser.
