Template Parameters Bundle Laravel Package

Product Decisions This Supports

• Dynamic Template Personalization: Enables A/B testing, localized content, or user-specific UI tweaks without hardcoding values in templates (e.g., "Welcome, {user.name}").
• Decoupling Logic from Presentation: Shifts dynamic template variables from Twig/HTML to PHP/Symfony services, improving maintainability and separation of concerns.
• Roadmap for Modular Theming: Foundation for a future "template engine" strategy, where themes/plugins can inject parameters without modifying core templates.
• Build vs. Buy: Avoids reinventing a templating system (e.g., custom Twig extensions) while offering more flexibility than static twig.global variables.
• Use Cases:
  • User dashboards with role-based UI elements.
  • Multi-tenant apps with tenant-specific branding.
  • Marketing campaigns with dynamic CTAs or promotions.

When to Consider This Package

• Adopt if:

  • Your Symfony app uses Twig templates and needs runtime parameter injection (e.g., user data, feature flags).
  • You’re avoiding hardcoded values in templates (e.g., {% if app.debug %}...{% endif %}).
  • You want a lightweight alternative to Twig extensions or custom services for simple parameter passing.
  • Your team prefers Symfony bundles over standalone libraries for consistency.

• Look elsewhere if:

  • You need complex template logic (e.g., nested conditionals, loops)—consider Twig filters/extensions or a dedicated templating engine (e.g., Twig’s {% include %} with dynamic paths).
  • Your app uses non-Symfony/PHP stacks (e.g., React, Vue).
  • You require real-time updates (e.g., WebSockets)—this is for server-rendered templates only.
  • The bundle’s maturity/star count is a concern (low adoption may indicate untested edge cases).

How to Pitch It (Stakeholders)

For Executives: "This bundle lets us dynamically customize templates (e.g., user-specific UI, A/B tests) without bloating our codebase. It’s a lightweight, Symfony-native solution that keeps our frontend logic clean and maintainable—ideal for scaling personalization without technical debt."

For Engineering: *"TemplateParametersBundle replaces manual Twig variable passing with a structured, bundle-based approach. Key benefits:

• Centralized parameters: Define once in PHP (e.g., config/parameters.yml) and reuse across templates.
• Symfony integration: Works with dependency injection, making it easy to extend (e.g., add caching for performance).
• Low risk: MIT-licensed, minimal setup, and avoids reinventing Twig extensions. Tradeoff: Limited to Symfony/Twig, but that’s our stack. Let’s prototype it for [specific use case] in 2 sprints."*

For Developers: *"Imagine replacing:

{% if user.is_premium %}
  <button class="premium">Upgrade</button>
{% endif %}

With:

// config/services.yaml
services:
  App\Service\PremiumFeatures:
    arguments: ['%premium_button_text%']  // Injected via bundle

The bundle handles the Twig injection automatically. Pros: Cleaner templates, easier testing. Cons: Add a layer of abstraction—we’ll need to document the parameter flow."*
