Install vuejs-datatable:




npm install vuejs-datatable

Step 5: Update Components

Here, we will write code on components, So let's update file and put bellow code:

resources/assets/js/components/ExampleComponent.vue




<template>

    <div class="container">

        <div class="row justify-content-center">

            <div class="col-md-8">

                <div class="card">

                    <div class="card-header">Laravel Vue Datatables Component Example - ItSolutionStuff.com</div>

  

                    <div class="card-body">

            </div>

        </div>

    </div>

</template>

  

<script>

  

    import DatatableFactory from 'vuejs-datatable';

  

    export default {

        components: { DatatableFactory },

        mounted() {

            console.log('Component mounted.')

        },

        data(){

            return {

                columns: [

                        {label: 'id', field: 'id'}, 

                        {label: 'Name', field: 'name'},

                        {label: 'Email', field: 'email'}

                    ],

                axios.get('/users').then(function(response){

                    this.rows = response.data;

                }.bind(this));

            }

        },

        created: function(){

            this.getUsers()

        }

    }

</script>

Step 6: Update welcome.blade.php

At last step, we will update our welcome.blade.php file. in this file we will use app.js file and use it, so let's update.

resources/views/welcome.blade.php




<!DOCTYPE html>

<html>

    <head>

        <meta charset="utf-8">

        <meta name="csrf-token" content="{{ csrf_token() }}">

        <meta http-equiv="X-UA-Compatible" content="IE=edge">

        <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Laravel Vue Datatables Component Example - ItSolutionStuff.com</title>

        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

        <link href="{{asset('css/app.css')}}" rel="stylesheet" type="text/css">

    </head>

    <body>

        <div id="app">

            <example-component></example-component>

        </div>

        <script src="{{asset('js/app.js')}}" ></script>

    </body>

</html>

Now you have to run below command for update app.js file:




npm run dev

Now you can check our example and also check demo and download free code.

We used vuejs-datatable npm package, you can get more information from here: vuejs-datatable.

vue : Laravel Vue JS File Upload Example

oday, we will learn file upload with laravel and vue js. we will create example of laravel vue axios file upload. we can easily fire post request using axios and pass file object as parameter, so we can store file to server using laravel 5.8.

If you are a developer, then you know about in today's web application. File upload is a primary task for every web app. The client always wants to file upload in his web application like a profile picture, product xls etc. But if you are working with vue.js then you think how it can be possible. But no issue, We will do it from scratch like install laravel, npm, vue, axios etc.

In this example, we will create a post route with a controller. In the controller method, we will write code of file upload. Then we will install npm, vue and axios. After that, we will write a code of the component. In a component file, we will write code of file upload using vue js. After finish all the step, you will get a layout like as below screenshot and you can also download code and check the demo.

Preview:

Step 1 : Install Laravel 5.8 Project

first of all, we will install Laravel 5.8 application using bellow command, So open your terminal OR command prompt and run bellow command:




composer create-project --prefer-dist laravel/laravel blog

Step 2: Create Route

In second step, we will create one post route and write file upload code. So, let's add new route on that file.

routes/web.php




Route::post('formSubmit','FileController@formSubmit');

Step 3: Create FileController

in this step, now we have create FileController with formSubmit methods, in this method we will write code of store file on server. So let's create controller:

app/Http/Controllers/FileController.php




<?php

   

namespace App\Http\Controllers;

   

use Illuminate\Http\Request;

   

class FileController extends Controller

{

    /**

     * success response method.

     *

     * @return \Illuminate\Http\Response

     */

    public function formSubmit(Request $request)

    {

        $fileName = time().'.'.$request->file->getClientOriginalExtension();

        $request->file->move(public_path('upload'), $fileName);

              

        return response()->json(['success'=>'You have successfully upload file.']);

    }

}

Step 4: NPM Configuration

Here, we have to first add setup of vue js and then install npm, so let's run bellow command in your project.

Install vue:




php artisan preset vue

Install npm:




npm install

Step 5: Write on app.js and Components

In this step, we will write code on app.js and then we will create vue js components, So let's create both file and put bellow code:

resources/assets/js/app.js




 

require('./bootstrap');

 

window.Vue = require('vue');

 

Vue.component('example-component', require('./components/ExampleComponent.vue'));

 

const app = new Vue({

    el: '#app'

});

resources/assets/js/components/ExampleComponent.vue




<template>

    <div class="container">

        <div class="row justify-content-center">

            <div class="col-md-8">

                <div class="card">

                    <div class="card-header">Laravel Vue JS File Upload Example - ItSolutionStuff.com</div>

    

                    <div class="card-body">

                        <div v-if="success != ''" class="alert alert-success" role="alert">

                          {{success}}

                        </div>

                        <form @submit="formSubmit" enctype="multipart/form-data">

                        <strong>Name:</strong>

                        <input type="text" class="form-control" v-model="name">

                        <strong>File:</strong>

                        <input type="file" class="form-control" v-on:change="onFileChange">

    

                        <button class="btn btn-success">Submit</button>

                        </form>

                    </div>

                </div>

            </div>

        </div>

    </div>

</template>

   

<script>

    export default {

        mounted() {

            console.log('Component mounted.')

        },

        data() {

            return {

              name: '',

              file: '',

              success: ''

            };

        },

        methods: {

            onFileChange(e){

                console.log(e.target.files[0]);

                this.file = e.target.files[0];

            },

            formSubmit(e) {

                e.preventDefault();

                let currentObj = this;

   

                const config = {

                    headers: { 'content-type': 'multipart/form-data' }

                }

    

                let formData = new FormData();

                formData.append('file', this.file);

   

                axios.post('/formSubmit', formData, config)

                .then(function (response) {

                    currentObj.success = response.data.success;

                })

                .catch(function (error) {

                    currentObj.output = error;

                });

            }

        }

    }

</script>

Step 6: Update welcome.blade.php

At last step, we will update our welcome.blade.php file. in this file we will use app.js file and use it, so let's update.

resources/views/welcome.blade.php




<!DOCTYPE html>

<html>

    <head>

        <meta charset="utf-8">

        <meta name="csrf-token" content="{{ csrf_token() }}">

        <meta http-equiv="X-UA-Compatible" content="IE=edge">

        <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Laravel Vue JS File Upload Example - ItSolutionStuff.com</title>

        <link href="{{asset('css/app.css')}}" rel="stylesheet" type="text/css">

    </head>

    <body>

        <div id="app">

            <example-component></example-component>

        </div>

        <script src="{{asset('js/app.js')}}" ></script>

    </body>

</html>

Now you have to run below command for update app.js file:




npm run dev

Make sure you created "upload" folder on your public directory.
