Composer is a tool that is widely used by PHP developers to manage their PHP dependencies. It is a popular tool that helps developers in developing their applications by installing and managing third-party libraries, frameworks, and applications. One of the famous PHP frameworks that is gaining a lot of attention in recent times is Laravel. Laravel is an open-source PHP web application framework that provides a wide range of tools and libraries to build web applications easily.
In this article, we aim to help developers with creating a Laravel 7 project using the Composer tool. We will provide an overview of what Composer is and how it works, and then guide you through the necessary steps to create a new Laravel 7 project. We will also provide some code examples to help you get started with your project.
What is Composer?
Composer is a dependency manager for PHP that allows developers to declare and manage the dependencies their project requires. It is widely used in the PHP community, and many popular PHP frameworks and CMS are using Composer to manage their dependencies. Composer works by reading a composer.json file and installing all the required packages defined in it. This file contains all the information about your project’s dependencies, including the name of the packages, the version, and other information.
Creating Laravel 7 project using Composer
Creating a new Laravel 7 project using Composer is pretty simple and straightforward. Follow the steps below to create a new Laravel 7 project:
Step 1: Install Composer
Before we can create a new Laravel 7 project with Composer, we must install Composer on our system. If you have already installed Composer on your system, you can skip this step. If not, you can follow the instructions on the official Composer website to install it.
Step 2: Create a new Laravel 7 project
Once you have installed Composer on your system, you can start creating a new Laravel 7 project. Open up a terminal or command prompt and navigate to the desired directory where you want to create your project. Once in that directory, run the following command to create a new Laravel 7 project:
composer create-project --prefer-dist laravel/laravel myproject "7.*"
This command will create a new Laravel 7 project in a new directory named "myproject". The "7.*" specifies that we want to create a project with Laravel version 7.x.
Step 3: Start Development Server
Once the project is created, we can start the development server. Navigate to the project directory using the terminal and run the following command:
php artisan serve
This command will start the Laravel development server, and you can access your project via the web browser by visiting http://localhost:8000.
Congratulations! You have successfully created a new Laravel 7 project using Composer.
Code Examples
Now that we have created a new Laravel 7 project, let's dive into some code examples to help you get started with your project.
Creating a new Controller
Controllers are an essential part of any Laravel project. They handle requests, perform logic, and return responses. To create a new controller in your Laravel project, run the following Artisan command:
php artisan make:controller MyController
This command will create a new controller file named "MyController.php" in the "app/Http/Controllers" directory. You can then open this file and start adding your controller logic.
Creating a new Route
Routes are used to map URLs to a specific controller action. To create a new route, open the "web.php" file located in the "routes" directory and define your route using the following syntax:
Route::get('/my-route', function () {
return 'Hello, World!';
});
This code will define a new route that will return "Hello, World!" when accessed via the URL "/my-route". You can replace the closure with a controller method to handle more complex logic.
Conclusion
In this article, we have walked you through the necessary steps to create a new Laravel 7 project using Composer. We also provided some code examples to help you get started with your project. Composer is a powerful tool that can help you manage your dependencies and streamline your development workflow. We hope this article has been helpful, and you are now ready to start building your Laravel 7 application. Happy coding!
let's dive deeper into some of the topics covered in the previous article.
Composer
Composer is a dependency manager for PHP that allows developers to easily declare and manage their project's dependencies. Developers can define the dependencies they need for their project using a composer.json file, which lists the required packages and their version.
When a developer runs the "composer install" command, Composer reads the composer.json file and installs all the required packages and their dependencies. This makes it easy for developers to manage dependencies and ensures that all the required packages are installed correctly.
Laravel
Laravel is an open-source PHP web application framework. It was created by Taylor Otwell in 2011, and it has quickly become one of the most popular PHP frameworks. Laravel provides a wide range of tools and libraries to help developers build web applications quickly and easily.
One of the reasons why Laravel has become so popular is that it follows the Model-View-Controller (MVC) architectural pattern. This pattern separates the application's data, user interface, and control logic into different components, making it easier for developers to build, test, and maintain their applications.
Laravel also provides many features to make web development easier, such as a built-in authentication system, routing system, and templating engine. It also comes with many pre-built packages that can be easily installed using Composer.
Creating a Controller
In Laravel, a controller is an essential component that handles the application's requests and returns a response. Controllers are the glue that connects the user interface (the views) and the data (the models) and performs any necessary logic between them.
To create a new controller in Laravel, developers can use the "php artisan make:controller" command. This command will create a new controller file in the "app/Http/Controllers" directory.
In the controller file, developers can define methods that handle the requests and perform any necessary logic. For example, a "show" method might retrieve data from a model and return it to the view.
Creating a Route
In Laravel, a route maps a URL to a specific controller action. This allows developers to access different parts of their application using a web browser.
To create a new route in Laravel, developers can add a new route definition to the "routes/web.php" file. A basic route definition looks like this:
Route::get('/', function () {
return view('welcome');
});
The code above defines a route that maps the URL "/" to a closure function that returns a view named "welcome". Developers can also map routes to controller actions using the following syntax:
Route::get('/users', 'UserController@index');
This code maps the URL "/users" to the "index" method of the "UserController" controller.
Conclusion
In summary, Composer and Laravel are two essential tools for PHP developers. Composer allows developers to manage dependencies easily, while Laravel provides a robust framework for building web applications. With Laravel's built-in tools for routing and controllers, developers can focus on building their applications' business logic without having to worry about the underlying infrastructure.
