Laravel 6 Angular JS CRUD Example Tutorial

Laravel 6 Angular JS CRUD Example Tutorial

Laravel 6 angular js crud tutorial. In this tutorial, we would love to share with you how you can create a crud application in laravel 6 using the angular js.

Angular js

AngularJS is a powerful JavaScript client-side Model-View-Controller (MVC) framework. It is especially popular for building single page applications that behavior like AJAX application.

Laravel 6 Angular JS CRUD Tutorial

  • Install Fresh Laravel Setup
  • Setup Database Credentials in .env
  • Create REST API Controller
  • Create a Model
  • Define Route
  • AngularJS application structure
    • AngularJS app.js
    • Create Angular js controller
  • Create blade view
  • Start development server

1). Install Fresh Laravel Setup

First of all, we need to install the laravel fresh application. Use the below command and download fresh new laravel setup :

composer create-project --prefer-dist laravel/laravel lara-angular

2). Setup Database Credentials in .env

In this step, go to your project directory and open .env file and set your database credentials like this:

 DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=databasename
DB_USERNAME=db_username
DB_PASSWORD=db_password

3). Create REST API Controller

In this step, we need to create a new controller name CustomerController. So open your command prompt and go to your project root directory than run the below-given command for creating a new CustomerController.

php artisan make:controller API/CustomerController --api

Now go to app/controller/API/CustomerController.php and update the below methods in your controller file:

<?php

namespace App\Http\Controllers\API;

use App\Customer;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Database\Eloquent\ModelNotFoundException;

class CustomerController extends Controller
{
    public function index()
    {
        return response()->json([
            'error' => false,
            'customers'  => Customer::all(),
        ], 200);
    }

    public function store(Request $request)
    {
        $validation = Validator::make($request->all(),[ 
            'name' => 'required',
            'email' => 'required|email|unique:customers,email',
            'contact_number' => 'required',
            'position' => 'required',
        ]);

        if($validation->fails()){
            return response()->json([
                'error' => true,
                'messages'  => $validation->errors(),
            ], 200);
        }
        else
        {
            $customer = new Customer;
            $customer->name = $request->input('name');
            $customer->email = $request->input('email');
            $customer->contact_number = $request->input('contact_number');
            $customer->save();
    
            return response()->json([
                'error' => false,
                'customer'  => $customer,
            ], 200);
        }
    }

    public function show($id)
    {
        $customer = Customer::find($id);

        if(is_null($customer)){
            return response()->json([
                'error' => true,
                'message'  => "Record with id # $id not found",
            ], 404);
        }

        return response()->json([
            'error' => false,
            'customer'  => $customer,
        ], 200);
    }

    public function update(Request $request, $id)
    {
        $validation = Validator::make($request->all(),[ 
            'name' => 'required',
            'email' => 'required|email',
            'contact_number' => 'required',
        ]);

        if($validation->fails()){
            return response()->json([
                'error' => true,
                'messages'  => $validation->errors(),
            ], 200);
        }
        else
        {
            $customer = Customer::find($id);
            $customer->name = $request->input('name');
            $customer->email = $request->input('email');
            $customer->contact_number = $request->input('contact_number');
            $customer->save();
    
            return response()->json([
                'error' => false,
                'customer'  => $customer,
            ], 200);
        }
    }

    public function destroy($id)
    {
        $customer = Customer::find($id);

        if(is_null($customer)){
            return response()->json([
                'error' => true,
                'message'  => "Record with id # $id not found",
            ], 404);
        }

        $customer->delete();
    
        return response()->json([
            'error' => false,
            'message'  => "Customer record successfully deleted id # $id",
        ], 200);
    }
}

4). Create a Model

Now we will create one eloquent model. So go to your command prompt and run the below command here:

php artisan make:model Customer

Next, go to app/customer.php and update the below code into your file:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Customer extends Model
{
    protected $fillable = [
        'id', 
        'name', 
        'email',
        'contact_number'
    ];
}

5). Define Route

In this step, we will define the route in routes/api.php file. So go to routes/api.php and update the below route into your file:

Route::group(['prefix' => 'v1','namespace' => 'API'], function(){      Route::apiResource('customers', 'CustomerController');  });

6). AngularJS application structure

Our application will have the following structure

laravel angular js application structure

Here :

  • app – contains all AngularJS related JavaScript files
  • app/controllers – contains all AngularJS controllers
  • css – contains all CSS files
  • js – contains all regular JavaScript files for our UI.

AngularJS app.js

In this step, we will create a new file name app.js. So go to /public/app, create a new file name app.js and update the below code into your app.js file:

This file will be used to define our application

var app = angular.module('customerRecords', [])
        .constant('API_URL', 'http://localhost:8000/api/v1/');

Here,

  • var app = angular.module('customerRecords', []) creates an AngularJS module and assigns the object to the variable app. All AngularJS files will be reference the variable app
  • .constant('API_URL', 'http://localhost:8000/api/v1/'); defines a constant variable with the API URL.

Create AngularJS controllers

Now /public/app/controllers and create a controller name customers.js controller. And update the below code into your customers.js file:

app.controller('customersController', function ($scope, $http, API_URL) {
    
    //fetch customers listing from 

    $http({
        method: 'GET',
        url: API_URL + "customers"
    }).then(function (response) {
        $scope.customers = response.data.customers;
        console.log(response);
    }, function (error) {
        console.log(error);
        alert('This is embarassing. An error has occurred. Please check the log for details');
    });

    //show modal form

    $scope.toggle = function (modalstate, id) {
        $scope.modalstate = modalstate;
        $scope.customer = null;

        switch (modalstate) {
            case 'add':
                $scope.form_title = "Add New Customer";
                break;
            case 'edit':
                $scope.form_title = "Customer Detail";
                $scope.id = id;
                $http.get(API_URL + 'customers/' + id)
                    .then(function (response) {
                        console.log(response);
                        $scope.customer = response.data.customer;
                    });
                break;
            default:
                break;
        }
        
        console.log(id);
        $('#myModal').modal('show');
    }

    //save new record and update existing record
    $scope.save = function (modalstate, id) {
        var url = API_URL + "customers";
        var method = "POST";

        //append customer id to the URL if the form is in edit mode
        if (modalstate === 'edit') {
            url += "/" + id;

            method = "PUT";
        }

        $http({
            method: method,
            url: url,
            data: $.param($scope.customer),
            headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
        }).then(function (response) {
            console.log(response);
            location.reload();
        }), (function (error) {
            console.log(error);
            alert('This is embarassing. An error has occurred. Please check the log for details');
        });
    }

    //delete record
    $scope.confirmDelete = function (id) {
        var isConfirmDelete = confirm('Are you sure you want this record?');
        if (isConfirmDelete) {

            $http({
                method: 'DELETE',
                url: API_URL + 'customers/' + id
            }).then(function (response) {
                console.log(response);
                location.reload();
            }, function (error) {
                console.log(error);
                alert('Unable to delete');
            });
        } else {
            return false;
        }
    }
});

HERE,

  • app.controller('customersController', function($scope, $http, API_URL) {...} defines a controller employeesController in the app variable that we created in /app/app.js. We have injected $scope$http, and a constant API_URL as dependencies
  • assigns response.employees to $scope.customersvariable. The $scope.customersvariable will be available in our view.
  • $scope.toggle = function(modalstate, id) {...} displays the modal form
  • $scope.save = function(modalstate, id){...} saves a new record or updates an existing record depending on whether the variable id has a value or not.
  • $scope.confirmDelete = function(id){...} deletes an existing record

7). Create a blade view

Now go to /resources/views and create a new file name index.blade.php and update the below code into your file:

<!doctype html>
<html lang="en" ng-app="customerRecords">
    <head>
        <!-- Required meta tags -->
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1,
            shrink-to-fit=no">

        <!-- Bootstrap CSS -->
        <link rel="stylesheet"
            href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"
            integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm"
            crossorigin="anonymous">

                        </tr>
                    </thead>
                    <tbody>
                        <tr ng-repeat="customer in customers">
                            <td>{{ customer.id }}</td>
                            <td>{{ customer.name }}</td>
                            <td>{{ customer.email }}</td>
                            <td>{{ customer.contact_number }}</td>
                            <td>

                                    ng-click="toggle('edit', customer.id)">Edit</button>
                                <button class="btn btn-danger btn-xs btn-delete"
                                    ng-click="confirmDelete(customer.id)">Delete</button>
                            </td>
                        </tr>
                    </tbody>
                </table>
            </div>
            <!-- Modal -->
            <div class="modal fade" id="myModal" tabindex="-1"
