Transforming props

Sometimes it can be useful to transform the props client-side before they are passed to the page component. For example, you may have a collection of errors that you want to convert into a custom Error object. You can do this using the transformProps callback.

new Vue({
  render: h =>
    h(Inertia, {
      props: {
        initialPage: JSON.parse(,
        resolveComponent: name => require(`./Pages/${name}`).default,
        transformProps: props => {
          return {
            errors: new Errors(props.errors),
