Flow Control Bundle Laravel Package

Product Decisions This Supports

• Multi-step workflows: Enables structured, step-by-step user journeys (e.g., e-commerce checkouts, onboarding, approval processes) without custom middleware or complex routing logic.
• Build vs. Buy: Avoids reinventing workflow engines (e.g., custom Symfony workflows or third-party SaaS) for internal tools or low-complexity flows.
• Roadmap prioritization: Justifies investing in a lightweight, PHP-native solution over heavier frameworks (e.g., Camunda, Temporal) for simple, linear flows.
• Use cases:
  • E-commerce: Checkout flows with validation gates (e.g., "Review cart → Payment → Confirmation").
  • Internal tools: Approval chains (e.g., "Request → Review → Approve") or guided forms.
  • MVP acceleration: Rapid prototyping of workflows without frontend frameworks (e.g., React Flow).

When to Consider This Package

• Adopt if:

  • Your workflows are linear, step-based, and low-complexity (no branching logic like "if-then-else" mid-flow).
  • You’re using Symfony/Laravel and want to avoid JavaScript-heavy solutions (e.g., React Flow, GoJS).
  • Your team lacks DevOps resources to manage external workflow engines (e.g., Camunda, AWS Step Functions).
  • You need server-side validation (e.g., blocking access to /payment unless /cart is completed).

• Look elsewhere if:

  • Your flows require dynamic branching (e.g., "If user is VIP, skip step X").
  • You need real-time collaboration (e.g., shared workflows with UI updates).
  • Your stack is non-PHP (e.g., Node.js, Python).
  • You need scalable orchestration (e.g., microservices coordination) → Consider Temporal or Camunda.
  • Your team prefers visual designers over YAML config → Evaluate tools like Flowable or n8n.

How to Pitch It (Stakeholders)

For Executives:

"This bundle lets us enforce structured user journeys (e.g., checkout flows) with minimal dev effort. Instead of building custom middleware or relying on third-party tools, we can define steps in YAML—like a server-side ‘wizard’—to guide users through critical paths (e.g., onboarding, approvals). It’s lightweight, PHP-native, and avoids vendor lock-in. For example, we could block access to the payment page until the cart is reviewed, reducing cart abandonment. Upfront cost: ~2 dev hours to integrate; long-term savings: no SaaS subscriptions or complex infrastructure."

For Engineering:

*"FlowControlBundle is a thin wrapper around devhelp/flow-control that enforces step-based navigation in Symfony/Laravel controllers. Key benefits:

• No frontend dependencies: Validation happens server-side (e.g., redirect users if they skip steps).
• Config-driven: Define flows in config.yml (e.g., my_checkout_flow: { moves: { cart: [home], payment: [cart] } }).
• Extensible: Hook into events for custom logic (e.g., logging, analytics).
• Low risk: Minimal stars/dependents reflect niche use, but the core concept is battle-tested in e-commerce.

Tradeoffs:

• Not for complex workflows (e.g., parallel paths, timeouts).
• Requires discipline to maintain YAML config as flows evolve.

Proposal: Pilot with a checkout flow or internal approval process. If it meets needs, we can extend it for other linear journeys."*
