It meitsjen fan in CRUD-app mei Laravel en Vue.js

Yn dizze tutorial sjogge wy tegearre hoe't jo de koade skriuwe fan in foarbyld CRUD-app, mei Laravel en Vue.js.

La Single Page Applikaasje sil tastean ús te foltôgjen in syklus fan basis operaasjes op DB: meitsje, lêze, update en wiskje mei Vue.js , Vue Router en Laravel Framework .

Tsjintwurdich binne de populêrste JS-frames Angular JS en Vue JS. Angular JS en Vue JS binne heul brûkerfreonlike en populêrste JS-ramten. It soarget foar behear fan it hiele projekt of applikaasje sûnder de side te ferfarskjen en krêftige jquery-validaasje.

Vue komt pre-ferpakt mei Laravel (tegearre mei Laravel Mix , in poerbêste skriuwersark basearre op webpack ) en lit ûntwikkelders begjinne mei it bouwen fan komplekse applikaasjes op ien side sûnder soargen te meitsjen oer transpilers, koadepakketten, boarnekaarten of oare "smoarge" aspekten fan moderne frontendûntwikkeling.

Tsjinner easken

Php 7.4

Laravel 8.x

MySQL

Ynstallearje it Laravel-projekt

Iepenje earst Terminal en fier it folgjende kommando út om in nij laravel-projekt te meitsjen:

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

of, as jo Laravel Installer ynstallearre hawwe as komponist globale ôfhinklikens:

laravel new crud-spa

Konfigurearje databankdetails:

Nei ynstallaasje Gean nei jo projektrootmap, iepenje it .env-bestân en set de databankdetails as folget yn:

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

Ynstallearje npm-ôfhinklikens

Rin it folgjende kommando út om de ôfhinklikens fan 'e front-end te ynstallearjen:

npm install

Dêrnei, ynstallearje view ,  vue-router  e vue-axios . Vue-axio's sille wurde brûkt om de Laravel-backend API te neamen. Laad it folgjende kommando op 'e terminal:

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

Meitsje migraasje, model en controller

Meitsje in kategorysjabloan, migraasje en kontrôler. Rinne dêrfoar it folgjende kommando út:

php artisan make:model Category -mcr

-mcr  dit ûnderwerp sil meitsje Model, Migraasje en Controller mei help fan ien kommando synteze.

Iepenje no it kategory migraasjebestân fan databases / migraasje en ferfange de koade yn 'e funksje op() :

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

Migrearje de databank mei it folgjende kommando:

php artisan migrate

No, iepenje de Category.php-sjabloan fanapp/Models  en bewurkje de koade yn it bestân 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'];

}

?>

Dêrnei, iepen CategoryController.php en foegje de koade ta yn 'e yndeks, bewarje, aktualisearje en wiskje metoaden as folget:

<?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!!'
        ]);
    }
}

Defifinish de rûtes yn web.php

Ora defiôfmeitsje harren routes yn triemmen web.php e api.php . Gean nei map routes en iepenje it bestân web.php en api.php en aktualisearje de folgjende 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']);

Meitsje in Vue app

Gean yn dizze stap nei de map boarne / views, meitsje de triem app.blade.php  en heakje de folgjende koade ta 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() }}"/>

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

Meitsje komponint foar Vue app

Gean yn dizze stap nei de map resource/js, meitsje de map components  en meitsje de bestannen as folget:

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

app. vue  it is it haadbestân fan ús Vue-app. Defiwy sille finish router-werjefte  yn dat bestân. Alle paden sille ferskine yn it bestân app. vue  .

Iepenje de triem Welcome.vue en bywurkje de folgjende koade yn dat bestân:

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

Iepenje de App.vue-bestân en bywurkje de koade as folget:

<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>

Dan, iepen resource / js / components / category / List.vue  en foegje de folgjende koade ta yn it bestân:

DefiFinish it paad nei de CRUD app yn Vue Router

No, jo moatte defifinish de Vue routes, en om dit te dwaan gean nei de map  resource / js , meitsje de triem route.js  en bywurkje de folgjende koade yn it bestân:

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

export const routes = [
    {
        name: 'home',

Hjir hawwe wy komponinten brûkt trage laden. Sjoch JS beheart it laden fan komponinten op in manier lazy mei paden, dus op 'e DOM kinne jo allinich komponinten lade as se nedich binne troch paden.

Ynklusyf Vue.js-ôfhinklikens yn app.js

No moatte jo alle paden, vue-aksio's en oare ôfhinklikens taheakje.

resource / js / app.js

require('./bootstrap');
import vue from 'vue'
window.Vue = vue;

import App from './components/App.vue';
import VueRouter from 'vue-router';
import VueAxios from 'vue-axios';
import axios from 'axios';
import {routes} from './routes';
 
Vue.use(VueRouter);
Vue.use(VueAxios, axios);
 
const router = new VueRouter({
    mode: 'history',
    routes: routes
});
 
const app = new Vue({
    el: '#app',
    router: router,
    render: h => h(App),
});
