Support InertiaJS 2.0

This release adds support for InertiaJS version 2.0, which is currently in pre-release: https://v2.inertiajs.com/.
@adonisjs/inertia 2.x will remain in beta while InertiaJS 2.x is in pre-release state.

Upgrade guide

First, update your frontend adapter:

npm install @inertiajs/vue3@next
// or
npm install @inertiajs/react@next
// or 
npm install @inertiajs/svelte@next

Then update the AdonisJS adapter:

npm install @adonisjs/inertia@beta

Breaking changes

• inertia.lazy is now inertia.optional.

No other breaking changes :)

New features

All the features mentioned in the Inertia documentation are also available with the AdonisJS adapter: https://v2.inertiajs.com/upgrade-guide. Specifically:

• Polling
• Prefetching
• Deferred props
• Infinite scrolling
• Lazy loading data on scroll

New prop types

To use some of the features mentioned above, you will need to use specific props. The API is simple and almost identical to Laravel's. We now have inertia.merge, inertia.defer, inertia.always, and inertia.optional:

return inertia.render('MyComponent', {
  mergeProp: inertia.merge(() => [1, 2, 3]),
  deferProp: inertia.defer(() => 'bar'),
  alwaysProp: inertia.always(() => 'always'),
  deferMergeableProp: inertia.defer(() => 'bar').merge()
})

Encryption API

See https://v2.inertiajs.com/history-encryption

The encryption API is an opt-in feature. You need to enable it in your config/inertia.ts file:

import { defineConfig } from '@adonisjs/inertia'

const inertiaConfig = defineConfig({
  // ...
  history: { encrypt: true },
})

Or you can also do it manually by route:

export class MyController {
  index({ inertia }) {
     inertia.clearHistory()
     inertia.encryptHistory(true)
     inertia.encryptHistory(false)
  }
}

@adonisjs/inertia 2.x will remain in beta while InertiaJS is in pre-release.
