Laravel installation with Composer - Performance & Optimization

Performance: Laravel installation with Composer

MEDIUM IMPACT

This affects the initial page load speed by determining how quickly Laravel's core files and dependencies are available for the application to run.

Installing Laravel framework dependencies for a new project

Laravel

composer create-project laravel/laravel myapp

Runs all setup scripts including autoload optimization and config caching, reducing runtime overhead and improving load speed.

📈 Performance Gainreduces initial app load time by up to 30%

Installing Laravel framework dependencies for a new project

Laravel

composer create-project laravel/laravel myapp --no-scripts

Skipping scripts disables essential setup tasks like autoload optimization and config caching, causing slower app startup and more runtime overhead.

📉 Performance Costblocks installation process longer later due to missing optimizations

Performance Comparison

Pattern	Dependency Setup	Autoloader Optimization	Runtime Overhead	Verdict
Skip scripts during create-project	Complete but unoptimized	No	High	[X] Bad
Standard create-project with scripts	Complete and optimized	Yes	Low	[OK] Good
Install without optimize-autoloader	Complete	No	Medium	[!] OK
Install with optimize-autoloader and no-dev	Complete and optimized	Yes	Low	[OK] Good

Rendering Pipeline

Laravel installation with Composer affects the server-side preparation of the application, which impacts how fast the server can respond with fully prepared HTML to the browser.

LCP

This affects the initial page load speed by determining how quickly Laravel's core files and dependencies are available for the application to run.

Optimization Tips

1Always run Composer with scripts enabled to ensure setup optimizations.

2Use --optimize-autoloader to speed up PHP class loading at runtime.

3Exclude development dependencies in production to reduce overhead.

Performance Quiz - 3 Questions

What is the impact of skipping Composer scripts during Laravel installation?

A Faster installation and faster app load

B Slower application startup due to missing optimizations

C No impact on performance

D Reduces bundle size significantly

DevTools: Network and Performance panels

How to check: Use Network panel to measure time to first byte and full HTML load; use Performance panel to record server response and page load timings.

What to look for: Look for reduced server response time and faster Largest Contentful Paint (LCP) indicating optimized backend setup.

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
