How to build modern web apps laravel 12 inertiajs reactjs 2026

People in the modern world need fast, innovative solutions for many things. When it comes to web application development, some apps are developed as SPAs (Single-Page Applications) while others are MPAs (Multi-Page Applications). SPAs are typically built with client-side programming languages like React, Vue, and Svelte, while MPAs are developed with server-side languages like PHP and Java.

What if someone needs to combine these approaches to build an app quickly? This might seem overwhelming. However, with the new features of Laravel 12 framework and InertiaJS, it's now very easy to integrate with React, Vue, and most other client-side languages.
