Laravel installation with Composer

Introduction

Laravel is a popular tool to build websites and apps. Composer helps you get Laravel ready quickly and correctly.

You want to start a new Laravel project on your computer.

You need to set up Laravel with all its parts automatically.

You want to make sure Laravel and its tools are the right versions.

You are preparing your computer to build web apps with Laravel.

Syntax

Laravel

composer create-project --prefer-dist laravel/laravel project-name

Replace project-name with your desired folder name for the Laravel app.

This command downloads Laravel and all needed files into that folder.

Examples

This creates a new Laravel project named blog.

Laravel

composer create-project --prefer-dist laravel/laravel blog

This installs Laravel version 10.x in a folder called myapp.

Laravel

composer create-project --prefer-dist laravel/laravel myapp "10.*"

Sample Program

This example shows how to create a Laravel project named mysite, then start a local server to see your app in a browser.

Laravel

# Open your terminal or command prompt
composer create-project --prefer-dist laravel/laravel mysite

# After installation, move into the project folder
cd mysite

# Start the Laravel development server
php artisan serve

Important Notes

Make sure you have PHP and Composer installed before running these commands.

Use php artisan serve to run your app locally after installation.

If you see permission errors, try running the command with proper rights or check your folder permissions.

Summary

Composer helps you install Laravel easily with one command.

Replace the project name to create your own app folder.

After installation, use Laravel's built-in server to start working on your app.

Practice

1. What is the main tool used to install Laravel easily with a single command?

easy

A. Composer

B. NPM

C. Git

D. Docker

Solution

1. Step 1: Understand Laravel installation tools

   Laravel uses Composer, a PHP package manager, to install its files easily.

2. Step 2: Identify the correct tool

   Composer is the official and recommended tool for Laravel installation, unlike NPM, Git, or Docker.

3. Final Answer:

   Composer -> Option A

4. Quick Check:

   Laravel installation tool = Composer [OK]

Hint: Remember Laravel uses Composer for PHP packages [OK]

Common Mistakes:

• Confusing Composer with NPM (JavaScript tool)
• Thinking Git installs Laravel automatically
• Assuming Docker installs Laravel by itself

2. Which of the following is the correct Composer command to create a new Laravel project named myapp?

easy

A. composer install laravel myapp

B. composer create-project laravel/laravel myapp

C. composer new laravel myapp

D. composer laravel create myapp

Solution

1. Step 1: Recall Composer command syntax for Laravel

   The correct command uses create-project followed by the package and project folder name.

2. Step 2: Match the command to options

   composer create-project laravel/laravel myapp matches the correct syntax: composer create-project laravel/laravel myapp.

3. Final Answer:

   composer create-project laravel/laravel myapp -> Option B

4. Quick Check:

   Correct Composer command = create-project [OK]

Hint: Use 'create-project' with package and folder name [OK]

Common Mistakes:

• Using 'install' instead of 'create-project'
• Wrong command order or missing package name
• Using 'new' or 'laravel create' which are invalid

3. After running composer create-project laravel/laravel blog, what folder will contain the Laravel app?

medium

A. laravel

B. public

C. vendor

D. blog

Solution

1. Step 1: Understand the command structure

   The last argument in the command is the folder name where Laravel installs the app.

2. Step 2: Identify the folder name

   Since the command ends with blog, the Laravel app is installed inside the blog folder.

3. Final Answer:

   blog -> Option D

4. Quick Check:

   Project folder = last argument 'blog' [OK]

Hint: Last word in command is your app folder name [OK]

Common Mistakes:

• Assuming 'laravel' is the folder name
• Confusing 'vendor' as the app folder
• Thinking 'public' is the main app folder

4. You ran composer create-project laravel/laravel without specifying a folder name. What will happen?

medium

A. Laravel installs in the current directory

B. Composer throws an error for missing folder name

C. Laravel installs in a folder named 'laravel'

D. Composer installs Laravel globally

Solution

1. Step 1: Check default behavior of create-project

   If no folder name is given, Composer uses the package name as the folder.

2. Step 2: Apply to Laravel package

   Since the package is laravel/laravel, it creates a folder named laravel.

3. Final Answer:

   Laravel installs in a folder named 'laravel' -> Option C

4. Quick Check:

   No folder name defaults to package name folder [OK]

Hint: No folder name? Uses package name as folder [OK]

Common Mistakes:

• Expecting an error for missing folder
• Thinking it installs in current folder
• Assuming global installation happens

5. After installing Laravel with Composer, which command starts the built-in Laravel development server inside your project folder?

hard

A. php artisan serve

B. composer start

C. php start server

D. laravel serve

Solution

1. Step 1: Recall Laravel's built-in server command

   Laravel uses the Artisan CLI tool, and the command to start the server is php artisan serve.

2. Step 2: Verify other options

   Options like composer start, php start server, and laravel serve are invalid commands.

3. Final Answer:

   php artisan serve -> Option A

4. Quick Check:

   Start server command = php artisan serve [OK]

Hint: Use 'php artisan serve' to start Laravel server [OK]

Common Mistakes:

• Trying 'composer start' which doesn't start Laravel server
• Using 'laravel serve' which is not a valid command
• Typing 'php start server' which is incorrect syntax
