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.

Core Web Vital Affected

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.
