How to generate Laravel framework

As the demand for web applications continues to increase, using frameworks to create software has become more and more popular. Laravel framework is a popular web application framework that provides many modern development tools and technologies to help you build complex web applications quickly.

This article will introduce you to the generation process of the Laravel framework. We'll go from installing Laravel to generating the initial application and then covering how to create database migrations and basic controller and view files.

1. Install Laravel

To install Laravel, you need to install PHP and Composer on your computer. After this, Laravel can be installed using Composer.

1. Install Laravel using Composer

Open a terminal (or command prompt) and navigate to the directory where you want to install Laravel. In that directory, type the following command:

composer create-project laravel/laravel my-projec

This will download the Laravel framework and create a directory called my-project. This directory contains all of Laravel's files and directories, as well as containing other dependencies required for building the application.

2. Generate the initial application

After successfully installing Laravel, you can use Laravel's command line tool to generate the initial structure of the Laravel application.

1. Generate initial application

Open a terminal and navigate to the directory where Laravel is installed. Enter the following command at the command line:

php artisan make:auth

This will create the authentication interface and generate the necessary files and directories such as controllers, views, and routes.

2. Run the application

To run the Laravel application, you can use the following command:

php artisan serve

This command will start Develop a web server that can access applications in a browser.

3. Create database migration

In Laravel, you can use migrations to manage the data structure of the database. Database migration is a repeatable method that allows you to easily add, modify, and undo the structure of database tables.

1. Create a new migration

To create a new database migration, enter the following command in the terminal:

php artisan make:migration create_posts_table

This command will create a new file in the migrations directory within the Laravel database migrations directory with a 13-bit naming scheme.

2. Modify migration

Open the migration file and use the Schema class provided by Laravel to define the object to be created. For example, here is an example of creating a table named "posts":

use IlluminateSupportFacadesSchema;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;

class CreatePostsTable extends Migration
{

public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->text('body');
        $table->timestamps();
    });
}

public function down()
{
    Schema::dropIfExists('posts');
}

}

This migration will create a table named "posts" in the database and include the fields "id", "title", "body" and the default timestamp of the database field.

3. Run the migration

To apply this migration and create the corresponding tables, run the following command in the terminal:

php artisan migrate

This will create the specified table.

4. Create basic controllers and views

1. Create controller

Use the following command to create a new controller in the terminal:

php artisan make:controller PostController

This will create a new PostController.php file located in the app/Http/Controllers directory.

2. Controller writing

In the new PostController.php file, add the following content to the beginning of the file:

namespace AppHttpControllers;

use IlluminateHttpRequest;

class PostController extends Controller
{

//

}

This code imports Laravel’s controller class and creates a new one named PostController Controller class.

Add the following method to handle the controller's actions:

public function index()
{

return view('posts.index');

}

This method will return a A view named "index" and controlled by a view file.

3. Create View

Use the following command to create a new view in the terminal:

php artisan make:view posts.index

This will create a view file named "index.blade.php". This file is located in the resources/views/posts directory.

4. View writing

In the newly created "index.blade.php" file, add the following content:

@extends('layouts. app')

@section('content')

<h1>All Posts</h1>

@endsection

This view is based on a layout named "layouts.app" and contains a page titled " All Posts" HTML element.

5. Summary

In this article, we introduced how to install the Laravel framework and generate an initial application, as well as how to use Laravel's database migration and controller/view files to create a web application. basic structure.

Using Laravel can create web applications faster and more conveniently, and provides many modern development tools and technologies, such as object-relational mapping (ORM), template engine, RESTful API, etc. Laravel has become a widely used web application framework, and whether you are a newbie or an experienced developer, it is a framework worth learning and using.
