Laravel 8 Vue JS Post Axios Request Tutorial

In this step by step tutorial we will learn to create post request with Vue JS post Axios in laravel. Please follow the instruction given below:

Step 1: Install Laravel 8 App
Step 2: Connecting App to Database

Step 3: Create Migration Files
Step 4: Create Models
Step 5: NPM Configuration

Step 6: Add Routes
Step 7: Create Controller By Command
Step 8: Create Vue Component

Step 9: Initialize Vue Components
Step 10: Run Development Server

Step 1: Install Laravel 8

First of all we need to create a fresh laravel project, download and install Laravel 8 using the below command

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

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

Step 2: Connecting App to Database

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

DB_CONNECTION=mysql 
DB_HOST=127.0.0.1 
DB_PORT=3306 
DB_DATABASE=here your database name here
DB_USERNAME=here database username here
DB_PASSWORD=here database password here

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=here your database name here

DB_USERNAME=here database username here

DB_PASSWORD=here database password here

Step 3: Create Migration Files

Now, in this step we will create migration file. Please run the following command:

php artisan make:migration create_countries_states_table

1	php artisan make:migration create_countries_states_table

Now open create_countries_states_table.php migration file from database>migrations and replace up() function with the following code:

<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateCountriesStatesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('countries', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->timestamps();
        });
        Schema::create('states', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->integer('country_id');
            $table->string('name');
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('countries');
        Schema::dropIfExists('states');
    }
}

<?php

use Illuminate\Support\Facades\Schema;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Database\Migrations\Migration;

class CreateCountriesStatesTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('countries', function (Blueprint $table) {

$table->bigIncrements('id');

$table->string('name');

$table->timestamps();

});

Schema::create('states', function (Blueprint $table) {

$table->bigIncrements('id');

$table->integer('country_id');

$table->string('name');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('countries');

Schema::dropIfExists('states');

}

Now, in this step we will create model and migration file. Please run the following command:

php artisan migrate

1	php artisan migrate

Step 4: Create Models

Now, in this step we will create model file. Please run the following command:

php artisan make:model Country
php artisan make:model State

1 2	php artisan make:model Country php artisan make:model State

Step 5: NPM Configuration

Install all Vue dependencies:

npm install

1	npm install

To calling Laravel API routes. You need to install vue-axios. So use run the following command on command prompt:

npm install vue-axios --save

1	npm install vue-axios --save

After installing all dependencies run this command:

npm run watch

1	npm run watch

Step 6: Add Routes

After this, we need to define routes in “routes/web.php” file. Lets open “routes/web.php” file and add the following routes in it.

routes/web.php

use App\Http\Controllers\CountryStateController;
 
Route::get('get_countries', [CountryStateController::class, 'getCountries']);
Route::post('get_states', [CountryStateController::class, 'getStates']);

use App\Http\Controllers\CountryStateController;

Route::get('get_countries', [CountryStateController::class, 'getCountries']);

Route::post('get_states', [CountryStateController::class, 'getStates']);

Step 7: Create Controller By Command

Now, lets create a controller named CountryStateController using command given below –

php artisan make:controller CountryStateController

1	php artisan make:controller CountryStateController

Now, go to app\Http\Controllers and open CountryStateController.php file. Then put the following code into your CountryStateController.php file:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Country;
use App\Models\State;
class CountryStateController extends Controller
{
    /**
     * Retrieve countries data
     *
     * @return void
     */
    public function getCountries()
    {
        $data = Country::get();
        return response()->json($data);
    }
    /**
     * Retrieve states data
     *
     */
    public function getStates(Request $request)
    {
        $data = State::where('country_id', $request->country_id)->get();
        return response()->json($data);
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Models\Country;

use App\Models\State;

class CountryStateController extends Controller

{

/**

* Retrieve countries data

* @return void

public function getCountries()

{

$data = Country::get();

return response()->json($data);

}

/**

* Retrieve states data

public function getStates(Request $request)

{

$data = State::where('country_id', $request->country_id)->get();

return response()->json($data);

}

Step 8: Create Vue Component

In this step we will create a vue component, go to resources/assets/js/components folder and create a filed called DropdownComponent.vue. And put the following code into your DropdownComponent.vue. components file:

<template>
    <div class="container">
        <div class="text-center" style="margin: 20px 0px 20px 0px;">
            <span class="text-secondary">Laravel 8 vue.js Dependent Dropdown Example</span>
        </div>
        <div class="row justify-content-center" style="margin: 20px 0px 20px 0px;">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-body">
                        <div class="form-group">
                            <label>Select Country:</label>
                            <select class='form-control' v-model='country' @change='getStates()'>
                                <option value='0' >Select Country</option>
                                <option v-for='data in countries' :value='data.id'>{{ data.name }}</option>
                            </select>
                        </div>
                        <div class="form-group">
                            <label>Select State:</label>
                            <select class='form-control' v-model='state'>
                                <option value='0' >Select State</option>
                                <option v-for='data in states' :value='data.id'>{{ data.name }}</option>
                            </select>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>
<script>
    export default {
        data(){
            return {
                country: 0,
                countries: [],
                state: 0,
                states: []
            }
        },
        methods:{
            getCountries: function(){
                axios.get('/get_countries')
                    .then(function (response) {
                        this.countries = response.data;
                    }.bind(this));
            },
            getStates: function() {
                axios.get('/get_states',{
                    params: {
                        country_id: this.country
                    }
                }).then(function(response){
                    this.states = response.data;
                }.bind(this));
            }
        },
        created: function(){
            this.getCountries()
        }
    }
</script>

<span class="text-secondary">Laravel 8 vue.js Dependent Dropdown Example</span>

</div>

<label>Select Country:</label>

<option value='0' >Select Country</option>

</select>

</div>

<label>Select State:</label>

<option value='0' >Select State</option>

</select>

</div>

</template>

export default {

data(){

return {

country: 0,

countries: [],

state: 0,

states: []

}

methods:{

getCountries: function(){

axios.get('/get_countries')

.then(function (response) {

this.countries = response.data;

}.bind(this));

getStates: function() {

axios.get('/get_states',{

params: {

country_id: this.country

}

}).then(function(response){

this.states = response.data;

}.bind(this));

}

created: function(){

this.getCountries()

}

</script>

Now open resources/assets/js/app.js and include the FileUpload.vue component like this:app.js

require('./bootstrap');
window.Vue = require('vue');
Vue.component('dropdown-component', require('./components/DropdownComponent.vue').default);
const app = new Vue({
    el: '#app',
});

require('./bootstrap');

window.Vue = require('vue');

Vue.component('dropdown-component', require('./components/DropdownComponent.vue').default);

const app = new Vue({

el: '#app',

});

Step 9: Initialize Vue Components

In this step, go to resources/views and create one folder named layouts. Inside this folder create one blade view file named app.blade.php file. Next, Navigate to resources/views/layouts and open app.blade.php file. Then update the following code into your app.blade.php file as follow:

<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="csrf-token" value="{{ csrf_token() }}"/>

</head>
<body>
<div id="app">
    <dropdown-component></dropdown-component>
</div>
<script src="{{ mix('js/app.js') }}" type="text/javascript"></script>
</body>
</html>

<!doctype html>

<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

<head>

<title>How to make dependent dropdown with Vue. js and Laravel

</title>

</head>

<body>

<dropdown-component></dropdown-component>

</div>

</body>

</html>
