Utilize Vus.js 2.0 in conjunction with Laravel 5.4 to pass an object to the application and allow for its global usage

How can I efficiently load the authenticated user and access it across all my Vue components without making unnecessary AJAX requests, as I can directly fetch it from the back-end?

In my Laravel home.blade.php file, I have a reference to a Vue app and attempted to bind the Auth::user() directly to the main Vue instance:

<div id="app" :authuser="{{ Auth::user() ? : '[]' }}"></div>

The content of my app.js file is as follows:

const app = new Vue({
  el: '#app',
  props: ['authuser'],
  data: { authuser: this.authuser }
});

However, it appears that passing props directly to the main Vue object may not work. What would be the most effective approach to achieve this?

Please note: Any suggestions aside from using props are welcome. Ideally, I aim to create a global reference to an authuser object that can be accessed by all Vue components. For instance, could this be achieved through window.authuser?

To achieve the desired outcome, simply include this code snippet in the blade template before calling app.js:

<script>
  let currentUser = {!! Auth::user() ? : '[]' !!};
</script>
<script src="{{asset('js/app.js') }}"></script>

By doing so, you can access the currentUser variable directly and universally across all components. For example:

<template>
  <div class="answer" v-if="currentUserAnswered">
     Edit Answer
  </div>
</template>

<script>
  export default {
    props: ['answer'],
    computed: {
      currentUserAnswered() { return currentUser.id == this.answer.user_id; }
    }
  }
</script>

This approach is more efficient than using this.$root repeatedly.

In the app.js file, it is possible to define global variables.

As an illustration:

// app.js
global.user = 'hello';

// In any other part of the code, you can reference the user variable
console.log(user);

This concept can also be extended to the vue object itself(if desired):

global.vm = new Vue({
    methods: {
        helloWorld(){}
    }
});

As a result, you can access its methods and functionalities from other components as well: vm.helloWorld();.

To bring the user into the app.js file, you may encode it in JSON within script tags. This way, your app.js will have access to it later on. For example:

<script>
    var user="{{$user}}";
</script>
<script src="app.js" type="text/javascript"></script>

Alternatively, utilizing an AJAX request might offer a more effective solution.

To achieve this, one method is to utilize the $root in Vue.js. As mentioned here, you can set it in the app component and access it in various components.

In your app.js:

const app = new Vue({
  el: '#app',
  created () {
    // This will be triggered the first time the router loads,
    // and will not run again until a page refresh
    // You could potentially load data dynamically here
    this.$root.authuser = this.authuser;
  }
});

Then, in your component:

this.$root.authuser

Another approach is to use a central state or implement Vuex, which is widely embraced by the community. You might find a similar solution detailed here. Within the created/mounted block of your app.js, you can commit changes to Vuex mutations and later access them throughout your application using getters.
