Like dislike system in vue js with laravel 8; In this tutorial, i am going to show you how to create like dislike system with Vue js in laravel 8 app.
You can enable a user to like or dislike a post only once and we can tell which users liked (or disliked) a particular post. We can query and display the list of all users who liked or disliked a particular post.
Laravel 8 Vue JS Like Dislike System Example
- Step 1: Install Laravel 8 App
- Step 2: Connecting App to Database
- Step 3: Run Make auth Command
- Step 4: Create Model And Migration
- Step 5: NPM Configuration
- Step 6: Add Routes
- Step 7: Create Controller By Command
- Step 8: Create Vue Component
- Step 9: Create Blade Views And Initialize Vue Components
- Step 10: Run Development Server
Step 1: Install Laravel 8 App
Execute the following command on terminal to install laravel latest application:
composer create-project --prefer-dist laravel/laravel blog
Step 2: Connecting App to Database
Go to your project root directory and open .env file. Then set up database credential in .env file as follow:
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: Run Make auth Command
Execute the following commands on terminal to make auth in laravel 8 app:
cd blog composer require laravel/ui --dev php artisan ui vue --auth
This laravel laravel/ui package provides a quick way to scaffold all of the routes, controller and views with authentication.
Step 4: Create Model And Migration
In this step, you need to execute the following command on terminal to create model and factory:
php artisan make:model Post -fm
php artisan make:model Post -fm
This command will create one model name post.php and also create one migration file for the posts table.
Now open create_postss_table.php migration file from database>migrations and replace up() function with following code:
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreatePostsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('title');
$table->string('slug');
$table->unsignedBigInteger('user_id');
$table->unsignedBigInteger('like')->default(0);
$table->unsignedBigInteger('dislike')->default(0);
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('posts');
}
}
Next, migrate the table using the below command:
php artisan migrate
Next, Navigate to app/Post.php and update the following code into your Post.php model as follow:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
use HasFactory;
protected $fillable = [
'title', 'description'
];
public function getRouteKeyName()
{
return 'slug';
}
}
Next, Navigate to database/factories and open PostFactory.php. Then update the following code into it as follow:
/** @var \Illuminate\Database\Eloquent\Factory $factory */
use App\Models\Post;
use Faker\Generator as Faker;
$factory->define(Post::class, function (Faker $faker) {
return [
'title' => $faker->sentence,
'slug' => \Str::slug($faker->sentence),
'user_id' => 1
];
});
and then execute the following command on terminal to generate fake data using faker as follow:
php artisan tinker //and then factory(\App\Models\Post::class,20)->create() exit
Step 5: NPM Configuration
Setup Vue and install Vue dependencies using NPM. So execute the following command on command prompt:
php artisan preset vue npm install
Step 6: Add Routes
Go to routes folder and open web.php file and add the following routes into your file:
routes/web.php
use App\Http\Controllers\PostController;
Route::get('post', [PostController::class, 'index']);
Route::get('post/{slug?}', [PostController::class, 'show'])->name('post');
Route::post('like', [PostController::class, 'getlike']);
Route::post('like/{id}', [PostController::class, 'like']);
Route::post('dislike', [PostController::class, 'getDislike']);
Route::post('dislike/{id}', [PostController::class, 'dislike']);
Step 7: Create Controller By Command
Execute the following command on terminal to create a controller by an artisan:
php artisan make:controller PostController
After that, go to app\Http\Controllers and open PostController.php file. Then update the following code into your PostController.php file:
<?php
namespace App\Http\Controllers;
use App\Models\Post;
use Facades\App\Repository\Posts;
use Illuminate\Http\Request;
class PostController extends Controller
{
public function index()
{
$posts = Post::latest()->get();
return view('posts',['posts' => $posts ]);
}
public function show(Post $slug)
{
return view('single-post',['post' => $slug ]);
}
public function getlike(Request $request)
{
$post = Post::find($request->post);
return response()->json([
'post'=>$post,
]);
}
public function like(Request $request)
{
$post = Post::find($request->post);
$value = $post->like;
$post->like = $value+1;
$post->save();
return response()->json([
'message'=>'Thanks',
]);
}
public function getDislike(Request $request)
{
$post = Post::find($request->post);
return response()->json([
'post'=>$post,
]);
}
public function dislike(Request $request)
{
$post = Post::find($request->post);
$value = $post->dislike;
$post->dislike = $value+1;
$post->save();
return response()->json([
'message'=>'Thanks',
]);
}
}
Step 8: Create Vue Component
Visit resources/assets/js/components folder and create a files called LikeComponent.vue and DisLikeComponent.vue.
Now, update the following code into your LikeComponent.vue components file:
<template>
<div class="container">
<p id="success"></p>
<a href="http://"><i @click.prevent="likePost" class="fa fa-thumbs-up" aria-hidden="true"></i>({{ totallike }})</a>
</div>
</template>
<script>
export default {
props:['post'],
data(){
return {
totallike:'',
}
},
methods:{
likePost(){
axios.post('/like/'+this.post,{post:this.post})
.then(response =>{
this.getlike()
$('#success').html(response.data.message)
})
.catch()
},
getlike(){
axios.post('/like',{post:this.post})
.then(response =>{
console.log(response.data.post.like)
this.totallike = response.data.post.like
})
}
},
mounted() {
this.getlike()
}
}
</script>
Next, update the following code into DisLikeComponent.vue file as follow:
<template>
<div class="container">
<p id="success"></p>
<a href="http://"><i @click.prevent="disLikePost" class="fa fa-thumbs-down" aria-hidden="true"></i>({{ totalDislike }})</a>
</div>
</template>
<script>
export default {
props:['post'],
data(){
return {
totalDislike:'',
}
},
methods:{
disLikePost(){
axios.post('/dislike/'+this.post,{post:this.post})
.then(response =>{
this.getDislike()
$('#success').html(response.data.message)
})
.catch()
},
getDislike(){
axios.post('/dislike',{post:this.post})
.then(response =>{
console.log(response.data.post.dislike)
this.totalDislike = response.data.post.dislike
})
}
},
mounted() {
this.getDislike()
}
}
</script>
Now open resources/assets/js/app.js and include the LikeComponent.vue and DisLikeComponent.vue component as follow:
require('./bootstrap');
window.Vue = require('vue');
Vue.component('like-component', require('./components/LikeComponent.vue').default);
Vue.component('dis-like-component', require('./components/DisLikeComponent.vue'));
const app = new Vue({
el: '#app',
});
Step 9: Create Blade Views And Initialize Vue Components
Go to resources/views and create one folder named layouts. Inside this folder create one blade view file named app.blade.php file.
Next, Navigate to resources/views/layouts and open app.blade.php file. Then update the following code into your app.blade.php file as follow:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="csrf-token" content="{{ csrf_token() }}">
<title>Laravel 8 Vue JS Like Dislike Example - Laratutorials.com</title>
<script src="{{ asset('js/app.js') }}" defer></script>
<link href="{{ asset('css/app.css') }}" rel="stylesheet">
@stack('fontawesome')
</head>
<body>
<div id="app">
<main class="py-4">
@yield('content')
</main>
</div>
</body>
</html>
Next, Navigate to resources/views/ and create one file name posts.blade.php. Then update the following code into your posts.blade.php file as follow:
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Post Lists</div>
<div class="card-body">
<ul>
@foreach ($posts as $item)
<a href="{{ route('post',$item->slug) }}"><li>{{ $item->title }}</li></a>
@endforeach
</ul>
</div>
</div>
</div>
</div>
</div>
@endsection
Again, Navigate to resources/views/ and create one file name single-post.blade.php. Then update the following code into your single-post.blade.php file as follow:
@extends('layouts.app')
@push('fontawesome')
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
@endpush
@section('content')
<div class="container">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header">Post Detail</div>
<div class="card-body">
<ul>
<li>{{ $post->title }}</li>
<like-component :post="{{ $post->id }}"></like-component>
<dis-like-component :post="{{ $post->id }}"></dis-like-component>
</ul>
</div>
</div>
</div>
</div>
</div>
@endsection
Step 10: Run Development Server
Now, execute the following command on terminal to start the development server:
npm run dev or npm run watch
