inventory angular with laravel

Introduction

Inventory management is an essential feature in many e-commerce applications, and Angular is a popular front-end framework used to build complex web applications. In this tutorial, we will explore how to use the Inventory Angular library with Laravel to manage products and their quantities. We will cover the installation, configuration, and usage of the Inventory Angular library in a Laravel project.

Prerequisites

Before starting this tutorial, make sure you have the following:

• Node.js installed on your machine
• Angular CLI installed (you can install it by running npm install -g @angular/cli)
• Laravel installed on your machine (version 8 or higher)
• A basic understanding of HTML, CSS, and JavaScript
• A Laravel project set up with a database

Step 1: Install the Inventory Angular Library

To install the Inventory Angular library, run the following command in your terminal:

npm install @inventory-ng/inventory

This will install the library and its dependencies.

Step 2: Create an Angular Component

Create a new Angular component by running the following command:

ng generate component ProductInventory

This will create a new directory product-inventory with the following files:

• product-inventory.component.ts
• product-inventory.component.html
• product-inventory.component.css

Step 3: Configure the Inventory Angular Library

In the product-inventory.component.ts file, add the following code to configure the Inventory Angular library:

import { Component } from '@angular/core';
import { InventoryService } from '@inventory-ng/inventory';

@Component({
  selector: 'app-product-inventory',
  templateUrl: './product-inventory.component.html',
  styleUrls: ['./product-inventory.component.css']
})
export class ProductInventoryComponent {

  products = [];

  constructor(private inventoryService: InventoryService) { }

  ngAfterViewInit() {
    this.inventoryService.getProducts().subscribe(products => {
      this.products = products;
    });
  }

}

In this code, we inject the InventoryService from the @inventory-ng/inventory library and use it to retrieve a list of products.

Step 4: Create a Template for the Component

In the product-inventory.component.html file, add the following code to create a template for the component:

<div>
  <h1>Product Inventory</h1>
  <table>
    <thead>
      <tr>
        <th>Product Name</th>
        <th>Quantity</th>
        <th>Action</th>
      </tr>
    </thead>
    <tbody>
      <tr *ngFor="let product of products">
        <td>{{ product.name }}</td>
        <td>{{ product.quantity }}</td>
        <td>
          <button (click)="incrementQuantity(product)">+</button>
          <button (click)="decrementQuantity(product)">-</button>
        </td>
      </tr>
    </tbody>
  </table>
</div>

In this code, we use the *ngFor directive to loop through the list of products and display their name, quantity, and action buttons.

Step 5: Implement the Logic for Incrementing and Decrementing Quantities

In the product-inventory.component.ts file, add the following code to implement the logic for incrementing and decrementing quantities:

incrementQuantity(product: any) {
  this.inventoryService.incrementQuantity(product).subscribe(() => {
    this.ngAfterViewInit();
  });
}

decrementQuantity(product: any) {
  this.inventoryService.decrementQuantity(product).subscribe(() => {
    this.ngAfterViewInit();
  });
}

In this code, we call the incrementQuantity and decrementQuantity methods of the InventoryService to update the quantity of the product. We then use the ngAfterViewInit method to retrieve the updated list of products.

Step 6: Configure the Laravel API

To use the Inventory Angular library with Laravel, we need to create an API endpoint that returns the list of products and their quantities. In the routes/api.php file of your Laravel project, add the following code:

Route::get('/products', 'ProductController@index');

In the app/Http/Controllers/ProductController.php file, add the following code:

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppModelsProduct;

class ProductController extends Controller
{
    public function index()
    {
        $products = Product::all();
        return response()->json($products);
    }
}

In this code, we define an API endpoint /products that returns a list of products.

Step 7: Consume the Laravel API

In the product-inventory.component.ts file, update the ngAfterViewInit method to consume the Laravel API:

ngAfterViewInit() {
  this.inventoryService.getProducts().subscribe(products => {
    this.products = products;
  });
}

getProducts() {
  return this.http.get('/api/products');
}

In this code, we use the HttpClient to retrieve the list of products from the Laravel API and pass it to the InventoryService.

That's it! You have now successfully integrated the Inventory Angular library with Laravel to manage products and their quantities.
