@inertiajs/core

What is @inertiajs/core?

@inertiajs/core is a JavaScript library that allows developers to build modern single-page applications (SPAs) using classic server-side routing and controllers. It provides a way to create reactive, dynamic web applications without the need for a full client-side framework.

What are @inertiajs/core's main functionalities?

Page Rendering

This feature allows you to render pages using Inertia. The code sample demonstrates how to set up an Inertia app with Vue.js, resolving pages dynamically and mounting them to the DOM.

import { createInertiaApp } from '@inertiajs/core';

createInertiaApp({
  resolve: name => require(`./Pages/${name}`),
  setup({ el, App, props }) {
    new Vue({
      render: h => h(App, props),
    }).$mount(el);
  },
});

Form Handling

Inertia provides a useForm hook to handle form submissions easily. The code sample shows how to create a form object, bind it to form fields, and submit it to a server endpoint with success handling.

import { useForm } from '@inertiajs/core';

const form = useForm({
  name: '',
  email: '',
});

form.post('/submit', {
  onSuccess: () => alert('Form submitted successfully!'),
});

Navigation

Inertia allows for seamless navigation between pages without full page reloads. The code sample demonstrates how to programmatically navigate to a different page using Inertia's visit method.

import { Inertia } from '@inertiajs/core';

function navigateToProfile() {
  Inertia.visit('/profile');
}

Other packages similar to @inertiajs/core

react-router

React Router is a standard library for routing in React applications. It allows for dynamic routing and navigation within React apps. Unlike @inertiajs/core, which integrates server-side routing with client-side rendering, React Router is purely client-side and requires a React environment.

vue-router

Vue Router is the official router for Vue.js, enabling navigation and routing in Vue applications. It provides similar client-side routing capabilities as React Router but is specific to Vue.js. In contrast, @inertiajs/core is framework-agnostic and can be used with multiple front-end frameworks.

next

Next.js is a React framework that provides server-side rendering and static site generation. It offers a more comprehensive solution for building full-stack applications compared to @inertiajs/core, which focuses on SPA-like behavior with server-side routing.
