README

Symfony Performance Analyzer is a smart CLI tool that automatically scans your codebase to instantly detect performance bottlenecks like N+1 queries and risky debug configurations. By providing a clear performance score and actionable insights, it helps developers ship faster, production-ready applications with absolute confidence.

📸 Analyzer in Action

✨ Features

🔍 N+1 Query Risk Detection: Uses advanced Abstract Syntax Tree (AST) parsing via nikic/php-parser to catch Doctrine entities fetching relations inside loops (The silent performance killer).
🐢 Slow Query Scanner: Analyzes the Symfony Profiler tokens to identify database queries exceeding 50ms without executing them.
⚙️ Production Config Check: Ensures APP_DEBUG is not accidentally left enabled, preventing massive memory leaks in production environments.
📊 Gamified Scoring System: Get a clear performance score (out of 100) to measure your app's health at a glance.
🤖 CI/CD & SaaS Ready: Export results in JSON format to seamlessly integrate with GitHub Actions, GitLab CI, or your custom SaaS dashboards.

📦 Installation

You can install the package via composer. It is highly recommended to install it as a development dependency:

composer require --dev aghar/symfony-perf-analyzer

🚀 Usage

Run the analyzer directly from your terminal at the root of your Symfony project:

php vendor/bin/perf-analyzer analyze

(By default, it will scan the current directory and display a beautiful console output with your performance score).

🔌 Custom Project Path

You can specify a different Symfony project path as an argument:

php vendor/bin/perf-analyzer analyze /path/to/your/symfony/project

⚙️ JSON Output (For CI/CD Pipelines)

If you want to parse the output in an automated CI pipeline or send it to an external SaaS dashboard, use the JSON format:

php vendor/bin/perf-analyzer analyze --format=json

🏗️ Extensible Architecture

The analyzer is built with a clean, decoupled architecture making it easy to add new rules:

src/Analyzer/Rules/: Contains the specific detection logic (AST traversing, regex, file scanning).
src/Formatter/: Handles the output rendering (Console UI or strict JSON).
src/Model/: Data structures representing violations and comprehensive reports.
