Crià una CRUD App cù Laravel è Vue.js

In stu tutoriale vedemu inseme cumu scrive u codice di un esempiu CRUD App, cù Laravel è Vue.js.

La Applicazione di una sola pagina ci permetterà di compie un ciculu di operazioni basi nantu à DB: creà, leghje, aghjurnà è sguassà cù Vue.js , Vue Routers è Quadru Laravel .

Oghje, i framework JS più populari sò Angular JS è Vue JS. Angular JS è Vue JS sò frameworks JS assai amichevuli è più populari. Fornisce a gestione di tuttu u prughjettu o l'applicazione senza rinfriscà a pagina è validazione jquery putente.

Vue vene pre-imballate cù Laravel (inseme cù Laravel Mix , un eccellente strumentu d'autore basatu nantu webpack ) è permette à i sviluppatori di cumincià à custruisce applicazioni cumplesse di una sola pagina senza preoccupassi di transpilers, pacchetti di codice, carte di fonte o altri aspetti "sporchi" di u sviluppu di frontend mudernu.

Requisiti di u servitore

PHP 7.4

Laravel 8.x

MySQL

Installa u prughjettu Laravel

Prima, apre u Terminal è eseguite u cumandimu seguitu per creà un novu prughjettu laravel:

composer create-project --prefer-dist laravel/laravel crud-spa

o, se avete installatu Laravel Installer cum'è una dipendenza globale di cumpusitore:

laravel new crud-spa

Configurate i dettagli di a basa di dati:

Dopu à a stallazione Andate à u cartulare di u vostru prughjettu, apre u schedariu .env è stabilisce i dettagli di a basa di dati cum'è seguita:

DB_CONNECTION=mysql 
DB_HOST=127.0.0.1 
DB_PORT=3306 
DB_DATABASE=<DATABASE NAME>
DB_USERNAME=<DATABASE USERNAME>
DB_PASSWORD=<DATABASE PASSWORD>

Installa dipendenze npm

Eseguite u cumandimu seguitu per installà e dipendenze front-end:

npm install

Dopu quì, installate vue ,  vue-router  e vue-axios . Vue-axios serà utilizatu per chjamà l'API di backend Laravel. Eseguite u cumandimu seguitu nantu à u terminal:

npm install vue vue-router vue-axios --save

Crea migrazione, mudellu è controller

Crea un mudellu di categuria, migrazione è controller. Eseguite u cumandimu seguitu per quessa:

php artisan make:model Category -mcr

- mcr  stu tema hà da creà Mudellu, Migrazione è Controller usendu sintesi di cumanda unicu.

Avà, apre u schedariu di migrazione categuria da basa di dati / migrazione è rimpiazzà u codice in a funzione su () :

public function up()
{
    Schema::create('categories', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('title');
        $table->text('description');
        $table->timestamps();
    });
}

Migrate a basa di dati cù u cumandimu seguitu:

php artisan migrate

Avà, apre u mudellu Category.php daapp/Models  è edità u codice in u schedariu model Category.php :

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model {

   use HasFactory;

   protected $fillable = ['title','description'];

}

?>

Dopu quì, apre CategoryController.php è aghjunghje u codice in l'indici, almacenà, aghjurnà è sguassate i metudi cum'è seguente:

<?php

namespace App\Http\Controllers;

use App\Models\Category;
use Illuminate\Http\Request;

class CategoryController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $categories = Category::all(['id','title','description']);
        return response()->json($categories);
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $category = Category::create($request->post());
        return response()->json([
            'message'=>'Category Created Successfully!!',
            'category'=>$category
        ]);
    }

    /**
     * Display the specified resource.
     *
     * @param  \App\Models\Category  $category
     * @return \Illuminate\Http\Response
     */
    public function show(Category $category)
    {
        return response()->json($category);
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Models\Category  $category
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Category $category)
    {
        $category->fill($request->post())->save();
        return response()->json([
            'message'=>'Category Updated Successfully!!',
            'category'=>$category
        ]);
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Models\Category  $category
     * @return \Illuminate\Http\Response
     */
    public function destroy(Category $category)
    {
        $category->delete();
        return response()->json([
            'message'=>'Category Deleted Successfully!!'
        ]);
    }
}

Defifinisce i Routes in web.php

Ora defifiniscili routes in i schedari web.php e api.php . Andà à u cartulare routes è apre u schedariu web.php è api.php è aghjurnà i seguenti routes:

routes/web.php

<?php
 
Route::get('{any}', function () {
    return view('app');
})->where('any', '.*');

routes/api.php

<?php
 
Route::resource('category',App\Http\Controllers\CategoryController::class)->only(['index','store','show','update','destroy']);

Crea una app Vue

In questu passu, andate à u cartulare risorsa / viste, crea u schedariu app.blade.php  è aghjunghje u codice seguente à app.blade.php:

<!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() }}"/>
        <title>Laravel Vue CRUD App</title>

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

Crea un cumpunente per l'app Vue

In questu passu, andate à u cartulare resource/js, crea u cartulare components  è crea i schedari cum'è seguita:

• View app
• Welcome.vue
• Category/List.vue
• Category/Add.vue
• Category/Edit.vue

app. vue  hè u schedariu principale di a nostra app Vue. Defifiniremu vista di u router  in quellu schedariu. Tutti i chjassi appariscenu in u schedariu app. vue  .

Aprite u schedariu Welcome.vue è aghjurnà u codice seguente in quellu schedariu:

<template>
    <div class="container mt-5">
        <div class="col-12 text-center">
            <h1>Laravel Vuejs CRUD</h1>
        </div>
    </div>
</template>

Aprite u schedariu App.vue è aghjurnà u codice cusì:

<template>
    <main>
        <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
            <div class="container-fluid">
                <router-link to="/" class="navbar-brand" href="#">Laravel Vue Crud App</router-link>
                <div class="collapse navbar-collapse">
                    <div class="navbar-nav">
                        <router-link exact-active-class="active" to="/" class="nav-item nav-link">Home</router-link>
                        <router-link exact-active-class="active" to="/category" class="nav-item nav-link">Category</router-link>
                    </div>
                </div>
            </div>
        </nav>
        <div class="container mt-5">
            <router-view></router-view>
        </div>
    </main>
</template>
 
<script>
    export default {}
</script>

Allora, apre resource / js / components / category / List.vue  è aghjunghje u seguente codice in u schedariu:

DefiFinite a strada per l'app CRUD in Vue Router

Avà, duvete defifinisci lu Vue routes, è per fà questu vai à u cartulare  resource / js , crea u schedariu route.js  è aghjurnà u codice seguente in u schedariu:

const Welcome = () => import('./components/Welcome.vue' /* webpackChunkName: "resource/js/components/welcome" */)
