What is the most efficient way to transfer data from PHP Laravel to Vue.js and automatically update a Vue.js component whenever the data is modified?

New to Vue.js and feeling a bit lost about how reactivity works with it. I want to send data from PHP Laravel to a Vue.js component and have the component update automatically when the data changes.

I've come across suggestions on Stack Overflow recommending the use of props to pass data from a Laravel Blade template to a Vue.js component. An example can be found here.

While I got this initial setup working, I'm stuck on how to make the component update dynamically when the data changes post page-load.

My specific scenario involves a report table on a web page where user interactions trigger an Ajax call to a Laravel controller action that fetches new data for the report from the database.

The updated data, available as a PHP array or JSON, is successfully passed to the client-side JS. However, I am unsure how to notify the Vue.js component responsible for rendering the report to re-render based on the new data received. Is there a method to "update props" so Vue.js recognizes the change and automates the re-rendering process?

This is where my research has hit a dead end. Any guidance would be much appreciated. Thank you.

Answer №1

Are you utilizing Ajax outside of the Vue component or within it as a method?

I have an instance of how I dynamically refresh the Vue data from inside the component itself. Although I am unsure about allowing external JS to directly update the Vue component, exploring this option could be beneficial. In my case, I use axios instead of traditional Ajax (Axios is automatically included in most Laravel installations post version 5.5).

<template>
    <div>
        <div id="reports">
            <!-- Displaying data -->
            {{ reports }}
        </div>
        <button @click="refreshReports">Refresh</button>
    </div>
</template>

<script>
    export default {
        data() {
            return {
                endpoint: '/api/MY_ROUTE/'
            };
        },

        props: {
            reports: Object
        },

        methods: {
            // Making Axios call to API endpoint
            refreshReports() {
                // GET request
                axios.get(this.endpoint)
                    .then(({data}) => {
                        this.reports = data.data;
                    });

                // POST request
                axios.post(this.endpoint, {
                    KEY: 'VALUE',
                }).then(({data}) => {
                    this.reports = data.data;
                });
                
                /*
                    `data.data` assumes the returned response is a JSON Resource

                    If incorrect data is being returned, add a `console.log(data)` to analyze the output!
                 */
            }
        }
    };
</script>

In your routes/api.php file, ensure there is a route similar to:

// GET request
Route::get('MY_ROUTE', 'ReportController@getReports');

// POST request
Route::post('MY_ROUTE', 'ReportController@getReports');

Your Controller should contain a method like:

// app/Http/Controllers/ReportController
public function getReports(Request $request) {
    return Reports::all();
}

Does that clarify things?

Update:

I'm uncertain about having an external JS script directly update the Vue component

You can import external JS scripts and utilize their functions within methods, although I have not personally implemented this before.

Something along the lines of:

<script>
import { myFunction } from '../external.js'

export default {
    methods: {
        refreshReports() {
            // Unsure if this approach is correct, merely a suggestion!
            this.reports = myFunction();
        }
    }
};
</script>
