Requirements Checker Laravel Package

Product Decisions This Supports

• Infrastructure as Code (IaC) & DevOps Enablement: Automate pre-deployment checks to ensure environments meet Symfony’s requirements (PHP version, extensions, system libraries), reducing manual QA overhead and deployment failures.
• Self-Service Developer Onboarding: Embed checks in CI/CD pipelines or local development tools (e.g., Docker, Vagrant) to surface missing dependencies before developers waste time debugging "works on my machine" issues.
• Multi-Environment Consistency: Enforce parity between dev/staging/prod by validating requirements early, especially critical for teams adopting Symfony for greenfield projects or migrations.
• Cost Optimization: Avoid spinning up cloud instances or containers with misconfigured dependencies by validating requirements upfront (e.g., AWS Lambda, Heroku).
• Compliance & Auditing: Log requirement checks for audits (e.g., "PHP 8.1+ required for Symfony 6.x") to justify technical debt decisions or vendor lock-in tradeoffs.
• Roadmap for "Shift Left" Testing: Integrate with IDE plugins (e.g., PHPStorm) or CLI tools to provide real-time feedback, aligning with DevOps principles of shifting quality left.

When to Consider This Package

• Adopt if:

  • Your stack includes Symfony (or PHP frameworks with similar dependencies like Laravel, Doctrine).
  • You manage multi-tier environments (dev/staging/prod) where configuration drift is a risk.
  • Your team lacks dedicated DevOps/SRE resources to manually validate environments.
  • You’re migrating to Symfony or adopting it for a new project and need to ensure baseline compatibility.
  • Your CI/CD pipeline lacks pre-flight checks for infrastructure dependencies.

• Look elsewhere if:

  • Your application uses non-PHP stacks (Node.js, Go, etc.) or frameworks with unique requirements (e.g., Ruby on Rails).
  • You have custom infrastructure (e.g., bare-metal servers) where manual checks are already rigorous.
  • Your team prioritizes runtime dependency injection (e.g., dynamic PHP extensions) over static checks.
  • You’re using Symfony Flex or Platform.sh, which handle dependency resolution automatically (though checks may still complement these tools).

How to Pitch It (Stakeholders)

For Executives/Business Leaders: "This package is a ‘firewall’ for our Symfony-based applications, ensuring our dev and production environments are always compatible before code even deploys. Think of it like a seatbelt for infrastructure—it prevents costly outages caused by missing PHP extensions or outdated versions. For example, if we deploy to a server missing the pdo_mysql extension, this catches it automatically, saving hours of debugging. It’s a low-effort way to reduce technical debt and improve deployment reliability, especially as we scale Symfony across more projects."

For Engineering/DevOps Teams: *"The symfony/requirements-checker package lets us bake compliance into our pipeline—no more ‘it works on my machine’ wars. We can:

• Automate pre-deployment gates in GitHub Actions, GitLab CI, or Jenkins to block misconfigured environments.
• Integrate with Docker/Vagrant to validate containers before they’re built (e.g., docker-compose build --requirements-check).
• Generate self-service docs for onboarding (e.g., ‘Run symfony check:requirements to debug your setup’). It’s lightweight (~200 stars, MIT-licensed), PHP-native, and plays well with Symfony’s ecosystem. The tradeoff? A few minutes upfront to configure checks vs. days lost to environment-related bugs."*

For Developers: *"This tool will save you time by catching infrastructure issues before you even run composer install. For example:

• Need to deploy to a shared host? It’ll tell you if they’re missing intl or xml extensions.
• Setting up a local dev environment? It’ll flag missing system libraries (e.g., libpq-dev for PostgreSQL). Just run symfony check:requirements in your terminal or embed it in a script. It’s like a php -v on steroids—no more ‘why isn’t my Symfony app working?’ mysteries."*
