Upgrade guide for v2.0 ​

What's new ​

Inertia.js v2.0 is a huge step forward for Inertia! The core library has been completely rewritten to architecturally support asynchronous requests, enabling a whole set of new features, including:

Additionally, for security sensitive projects, Inertia now offers a history encryption API, allowing you to clear page data from history state when logging out of an application.

Upgrade dependencies ​

To upgrade to the Inertia.js v2.0 beta, first use npm to install the client-side adapter of your choice:

vue
npm install @inertiajs/vue3@^2.0

Next, use at least the 3.6 version of inertia-rails.

ruby
gem 'inertia_rails', '~> 3.6'

Breaking changes ​

While a significant release, Inertia.js v2.0 doesn't introduce many breaking changes. Here's a list of all the breaking changes:

Dropped Vue 2 support ​

The Vue 2 adapter has been removed. Vue 2 reached End of Life on December 3, 2023, so this felt like it was time.

Svelte adapter ​

  • Dropped support for Svelte 3 as it reached End of Life on June 20, 2023.
  • The remember helper has been renamed to useRemember to be consistent with other helpers.
  • Updated setup callback in inertia.js. You need to pass props when initializing the App component. See the updated guide
  • The setup callback is now required in ssr.js. See the updated guide

Partial reloads are now async ​

Previously partial reloads in Inertia were synchronous, just like all Inertia requests. In v2.0, partial reloads are now asynchronous. Generally this is desirable, but if you were relying on these requests being synchronous, you may need to adjust your code.
