Introduction:

In this blog, you’ll learn how to develop a Laravel 11 AJAX CRUD application through an easy step-by-step tutorial. But before we dive in, let’s start with some introductions:

Laravel is a free and open-source PHP web framework designed for building web applications using the MVC (Model-View-Controller) architectural pattern. It simplifies web development by providing built-in features that speed up and ease the process.

AJAX (Asynchronous JavaScript and XML) is a collection of web development techniques that use various web technologies to enable web applications to operate asynchronously, enhancing user experience.

CRUD stands for Create, Read, Update, and Delete—the four fundamental operations in any programming environment, typically related to database management:

• Create: Generate new records.
• Read: Retrieve or view existing records.
• Update: Modify existing records.
• Delete: Remove or destroy records.

Prerequisite:
Composer
MySQL
PHP >= 8.2

Step 1: Install Laravel 11

First, choose a folder where you want to install Laravel. Then, run the following command in Terminal or CMD to install Laravel 11:

Install via Composer:

composer create-project laravel/laravel ajax-crud

Step 2: Configure Database Settings

Once the installation is complete, open the .env file and configure the database settings as follows:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name (e.g., crud_ajax)
DB_USERNAME=your_database_username (e.g., root)
DB_PASSWORD=your_database_password (e.g., root)

Step 3: Create Model and Database Migration

• Model: A class that represents a database table.
• Migration: Functions like version control for the database, enabling you to modify and share the database schema with your team.

Run the following command in the Terminal or CMD to create both a model and a migration:

php artisan make:model Project --migration

After executing this command, you’ll find a new file in the database/migrations directory. Add the code below to this migration file.

<?php
 
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
 
return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('projects', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->text('description');
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('projects');
    }
};

Execute the migration by running the following Artisan command:

php artisan migrate

Step 4: Create a Resource Controller

A Resource Controller manages all HTTP requests related to a specific resource within your application.

To generate a Resource Controller, run the following command:

php artisan make:controller ProjectController --api

This command will create a new controller file at app/Http/Controllers/ProjectController.php. The file will include methods for each of the standard resource operations. Open this file and add the necessary code as outlined below:

app/Http/Controllers/ProjectController.php

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use App\Models\Project;
 
class ProjectController extends Controller
{
    /**
     * Display a listing of the resource.
     */
    public function index()
    {
        $projects = Project::get();
        return response()->json(['projects' => $projects]);
    }
 
    /**
     * Store a newly created resource in storage.
     */
    public function store(Request $request)
    {
        request()->validate([
            'name' => 'required|max:255',
            'description' => 'required',
        ]);
   
        $project = new Project();
        $project->name = $request->name;
        $project->description = $request->description;
        $project->save();
        return response()->json(['status' => "success"]);
    }
 
    /**
     * Display the specified resource.
     */
    public function show(string $id)
    {
        $project = Project::find($id);
        return response()->json(['project' => $project]);
    }
 
    /**
     * Update the specified resource in storage.
     */
    public function update(Request $request, string $id)
    {
        request()->validate([
            'name' => 'required|max:255',
            'description' => 'required',
        ]);
   
        $project = Project::find($id);
        $project->name = $request->name;
        $project->description = $request->description;
        $project->save();
        return response()->json(['status' => "success"]);
    }
 
    /**
     * Remove the specified resource from storage.
     */
    public function destroy(string $id)
    {
        Project::destroy($id);
        return response()->json(['status' => "success"]);
    }
}

Step 5: Register Routes

Once you have created the resource controller, you need to register both the resourceful route and the view route.

In routes/web.php:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ProjectController;

Route::get('/', function () {
    return view('projects');
});

Route::apiResource('projects', ProjectController::class);

Step 6: Create a Blade File

Blade is Laravel’s simple yet powerful templating engine. Blade view files have the .blade.php extension and are typically stored in the resources/views/ directory.

To enhance the appearance of our simple CRUD app, we will use Bootstrap. Bootstrap is a popular, free, open-source CSS framework designed for building responsive and mobile-first web projects.

Create a Blade file named projects.blade.php in the resources/views/ directory. After creating the file, insert the following code:

resources/views/projects.blade.php

What is Typescript?

Typescript is a programming language developed by Microsoft that is a superset of JavaScript. It adds static typing capabilities to JavaScript, allowing developers to catch errors and improve code quality during development. TypeScript ultimately compiles down to plain JavaScript code.

What are the top use cases of Typescript?

TypeScript is a versatile language that can be used for a variety of purposes. Some of the top use cases of TypeScript include:

• Web development: TypeScript is a popular choice for developing web applications, as it can help to improve the maintainability and performance of code.
• Server-side development: TypeScript can also be used for server-side development, such as Node.js applications.
• Mobile development: TypeScript can be used to develop mobile applications for both Android and iOS.
• Desktop development: TypeScript can also be used to develop desktop applications.
• Game development: TypeScript is a popular choice for game development, as it can help to improve the performance and maintainability of code.

What are the features of Typescript?

TypeScript offers a number of features that make it a powerful and versatile language. Some of the key features of TypeScript include:

• Static typing: TypeScript is a statically typed language, which means that the types of variables and expressions are checked at compile time. This helps to prevent errors and make your code more reliable.
• Object-oriented programming: TypeScript supports object-oriented programming, which makes it a good choice for developing large and complex applications.
• Cross-platform: Cross-platform in Typescript refers to the ability of the code written in Typescript to run and work on multiple platforms or environments, such as web browsers, mobile devices (iOS, Android), desktop applications (Windows, macOS), and even server-side environments (Node.js).
• Static type checking: Static type checking in TypeScript is a process that ensures the correctness of types at compile-time. It checks the types of variables, function parameters, and return values based on their type annotations. This helps identify potential errors and avoid type-related bugs during development, enhancing code quality and maintainability.
• Functional programming: TypeScript also supports functional programming, which can be useful for developing code that is more concise and easier to read.
• Asynchronous programming: TypeScript supports asynchronous programming, which is essential for developing efficient and responsive applications.
• Modules: TypeScript supports modules, which makes it easy to organize your code and improve its readability.

What is the workflow of Typescript?

The workflow of TypeScript typically involves the following steps:

1. Install and configure TypeScript: TypeScript can be installed via npm using the command `npm install -g typescript`. A `tsconfig.json` file is commonly used to configure compilation options.

2. Write TypeScript code: Create a `.ts` file and write TypeScript code with type annotations, interfaces, and classes.

3. Compile TypeScript: Run the command `tsc` in the command line to compile TypeScript code into JavaScript.

4. Use the compiled JavaScript: The TypeScript compiler generates a `.js` file that can be used in any JavaScript environment or included in HTML files.

How Typescript Works & Architecture?

Here is how TypeScript works:

1. The TypeScript compiler reads your TypeScript code.
2. The compiler checks your code for errors, including type errors.
3. If there are no errors, the compiler converts your TypeScript code to JavaScript.
4. The JavaScript code is then executed.

The TypeScript compiler is written in TypeScript itself. This makes it easy to extend the compiler with new features.

The TypeScript architecture is divided into three layers:

• Parser: The parser reads your TypeScript code and converts it into an abstract syntax tree (AST).
• Checker: The checker checks the AST for errors, including type errors.
• Generator: The generator converts the AST back into JavaScript code.

How to Install and Configure Typescript?

To install and configure TypeScript, follow these steps:

Step 1: Install Node.js

– TypeScript requires Node.js to be installed on your computer.

– Visit https://nodejs.org and download the appropriate installer for your operating system.

– Run the installer and follow the instructions to complete the installation.

Step 2: Install TypeScript

– Open a terminal or command prompt.

– Use the following command to install TypeScript globally:

npm install -g typescript

Step 3: Verify the Installation

– To verify that TypeScript is installed, enter the following command in the terminal:

tsc --version

– If it shows the version number, TypeScript is installed correctly.

Step 4: Create a TypeScript Configuration File (optional)

– Create a new folder for your TypeScript project.

– Open a terminal or command prompt and navigate to the project folder.

– Run the following command to initialize a TypeScript project and create a tsconfig.json file:

tsc --init

– This command creates a default tsconfig.json file in the project folder.

Step 5: Configure the tsconfig.json File (optional)

– Open the tsconfig.json file in a text editor.

– Update the compiler options based on your needs. For example, you can change the “target” option to specify the version of ECMAScript you are compiling to, or the “outDir” option to specify the output folder for the compiled JavaScript files.

– For more information, refer to the TypeScript documentation on compiler options: https://www.typescriptlang.org/tsconfig

Step 6: Write TypeScript code

– Create a new .ts file in your project folder.

– Write TypeScript code in the file.

– For example, you can create a file named `app.ts`:

let message: string = "Hello, TypeScript!";
console.log(message);

Step 7: Compile TypeScript to JavaScript

– Open a terminal or command prompt and navigate to the project folder.

– Run the following command to compile the TypeScript code to JavaScript:

tsc app.ts

– This command generates a corresponding JavaScript file (`app.js` in this example) in the same folder.

That’s it! You have successfully installed and configured TypeScript.

Step by Step Tutorials for Typescript for the hello world program

Here is a step-by-step tutorial on how to write a “hello world” program in TypeScript:

1. Create a new file called hello.ts.
2. Write the following code in the file:

console.log("hello world");

3. Save the file.
4. Compile the code by running the following command:

tsc hello.ts

5. This will create a file called hello.js.
6. Run the JavaScript file by running the following command:

node hello.js

This will print the message “hello world” to the console.

Here is a breakdown of the code:

• The console.log() function is used to print a message to the console.
• The string literal “hello world” is the message that will be printed to the console.

The tsc command is used to compile TypeScript code to JavaScript. The hello.ts file is the TypeScript file that we want to compile.

The node command is used to run JavaScript code. The hello.js file is the JavaScript file that we want to run.

What are feature of angular ?

Features of Angular:

• MVC (Model-View-Controller) architecture: Angular follows the MVC architecture, which separates the application’s data, presentation, and behavior. This makes the application easier to understand, test, and maintain.
• Two-way Data Binding: Angular allows for seamless synchronization between the model and the view, ensuring that any changes made in the model are immediately reflected in the view and vice versa.
• Dependency Injection: Angular makes use of dependency injection to manage the application’s components and their dependencies. This promotes code reusability and simplifies the development process.
• Directives: Angular’s directives enable developers to extend HTML with new attributes and tags, making it easier to create dynamic and interactive web applications.

What is the workflow of angular ?

The workflow of an Angular application typically involves the following steps:

1. Create an Angular project using the Angular CLI (Command Line Interface).

2. Define components, services, and modules to structure your application.

3. Write HTML templates and CSS styles for the user interface.

4. Implement data binding and handle user interactions within components.

5. Configure routing for navigating between different views.

6. Test your application using automated unit tests and end-to-end tests.

7. Build and deploy your application for production.

How angular Works & Architecture?

How Does Angular Work:

Angular works by combining HTML templates, CSS styles, and JavaScript code. When a user interacts with the application, Angular handles the events and updates the view accordingly. It uses a concept called two-way data binding, which means that changes in the model are automatically reflected in the view, and vice versa. 

Architecture of Angular: Angular follows a modular and scalable architecture, which makes it easy to maintain and extend the application. It consists of several key components:

1. Modules: Angular applications are divided into modules, which are self-contained units of functionality. Each module can have its own components, services, and other resources.
2. Components: Components are the building blocks of Angular applications. They encapsulate the user interface and handle user interactions. Each component consists of a template, styles, and code.
3. Services: Services provide functionality that can be shared across multiple components. They are used to manage data, perform HTTP requests, and handle other tasks.
4. Directives: Directives are used to extend the functionality of HTML elements. They allow you to add custom behavior to existing elements or create new elements.
5. Templates: Templates define the structure and layout of the user interface. They are written in HTML and can include Angular-specific syntax.
6. Dependency Injection: Angular uses dependency injection to manage the dependencies between different components and services. This allows for loose coupling and easier testing.

Some of its implications, such as data science, are an essential part of almost every industry now, including web development.

Data Science In Web Development

It is almost impossible to imagine our lives without apps that use the internet, also known as web apps. They are a huge part of boosting the daily efficiency of our lives and giving us conveniences that we have come to take for granted, such as enjoying online entertainment.

Initially, the way web apps worked was based on hundreds of surveys done on focus groups, which helped give an idea of what people wanted. Combined with a few educated guesses, we got the classic apps that launched the industry. However, things are different today. Focus groups have largely been phased out, and there is almost no need for any guesswork because there is so much data available on almost every subject under the sun.

Our connected world generated billions of gigabytes of data every day. Everyone chips in, and this data is collected and analyzed every second. The end result is a market and industry insights that companies then act upon, making them seem like mind readers or future predictors and time travelers of some sort because it gives them the power to anticipate your wants and needs even before you know what you want or need. Having in mind the importance of a great website, making use of these data and constantly upgrading your website, means that you will stay ahead of the competition and fulfill the needs of your customers.

In web development, the application of data science can also transform and improve the entire industry. Some ways that data science can help include

1. Automatic Updates and Upgrades

Through data science, it is possible for machines to analyze the generated data and introduce newer versions of software and apps that are tailored towards that data. The users will be the dictators of what they like and what they don’t, and the software conforms to their needs in every update and upgrade.

2. Production of Software

Instead of developers adding features to the software based on what they feel the users want, through data science, it is possible to analyze other similar products and see what users like or don’t like, then implement these lessons in your new software.

3. PersonalizationData science allows web apps to understand users better. With the integration of AI, the apps can learn from you and customize themselves to suit you better. The data you generate using the web app ends up improving your own user experience.4
4.  PredictionsThrough data science, it is possible to predict trends and future user needs. This helps developers anticipate market surges and tailor-make products to take advantage of these future scenarios. Data science can massively transform the web design industry if the well-taken advantage of.

For instance, we all know the rise of Stories on social media platforms and how interactive they are getting with the users. Many businesses have seen the importance of content visualization and how important it is to use it. Even Google has launched “stories for web” platform, where websites can share their content in a story format, which makes it more readable to their audience.

So What Potential Do Data-Driven Apps Have?

Any organization that takes advantage of data science in its day to day business has a clear competitive edge over its competition. Within the next few years, this will become a requirement for one to thrive in such a business environment, much like cell phones are to us today.

Data science has a real impact in many areas. It promises improved efficiency, unmatched productivity, and personalization.

1. Productivity and Efficiency

Through Data Science, a website can boost the productivity of its user. For example, if you have a website that remembers the users’ preferences from their last visit, you save the user a lot of time and energy that could have otherwise been spent logging in details afresh. Similarly, AI can learn users spending habits and general lifestyle. It can use this information to offer personalized suggestions, advice and generally make life online so much more efficient. This is why we have AI-virtual assistants.

2. Personalization

It is not uncommon for you to receive recommendations on your phone based on your location or previous spending habits or online activities and in the real world. This is already a reality today. More and more web apps are coming up with recommendation engines to tailor make and customize every user’s experience.

In web design, you can similarly take advantage of this fact and do the same thing. This is the current direction that mobile app development is taking.

The future is here, and its name is data science. If you are not taking advantage of it in your business, you have already been left behind. If you are a company that understands the importance of a great website, consider outsourcing to Europe. According to Tactical a New Jersey Company, there are many competing companies that understand the interrelationship between data science and good web development, which will push your business to the next level.
