About This package

This package allows you to transform the props you get from Inertia before getting them in your Vue Component. It's a good replacement for the old Interia transformProps which has been removed.

How to Install?

npm install inertiajs-transform-props

How to implement

Method 1 - Fully transform props while navigating

Using this function will transform all the props, even when navigating between the pages as SPA. All you need to do is to use createInertiaApp from this package instead of the one provided by Inertia.

import { createApp, h } from 'vue';
import { createInertiaApp } from 'inertiajs-transform-props';
//import { createInertiaApp } from '@inertiajs/inertia-vue3'

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

Method 2 - Directly in the access point

You can add this package to the app's entrepoint file ex app.ts or app.js, It will be just a replacement for the default h function provided by the vue core (Please note that the props will be transformed only in the first load of the page, to use it while navigating between pages check the previous method).

import { createApp } from 'vue';
import { h } from 'inertiajs-transform-props';
import { createInertiaApp } from '@inertiajs/inertia-vue3'

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

How to use it

In your page component you can just add the transform properity to your props object.

props: {
      article: {
          type: Object,
          required: true,
          transform: (originalValue) => { 
              originalValue.isPublished = true;
              return originalValue;
          }
      },
      comment: {
          type: String,
          required: true,
          transform: 'Anything'
      }
  }

You can also use it to convert the prop to a typescript model, just by passing the class or construct it inside a function:

props: {
      article: {
          type: Object as PropType<Article>,
          required: true,
          transform: Article
      },
      comment: {
          type: String,
          required: true,
          transform: (comment) => new Comment(comment)
      },
      replies: {
          type: Array as PropType<Reply[]>,
          required: true,
          transform: (replies) => replies.map(reply => new Reply(comment))
      },
  }
