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">

    <body>
        <div class="container" ng-controller="customersController">

            <div>
                <table class="table">

                            <th><button id="btn-add" class="btn btn-primary

                        </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="confirmDelete(customer.id)">Delete</button>
                            </td>
                        </tr>
                    </tbody>
                </table>
            </div>
            <!-- Modal -->
            <div class="modal fade" id="myModal" tabindex="-1"
