Stripe App Extension

The Challenge

Enterprise clients needed a Stripe-native solution for Italian electronic invoicing. The challenge was managing complex form state across 8 views without Redux, while staying within Stripe's app extension constraints.

The Solution

• 6-level React Context architecture replacing Redux for optimized performance
• 8 primary views with advanced form validation and conditional logic
• 173 memoization instances for render optimization in constrained environment
• Custom error boundary system for Stripe extension sandboxed runtime

Results

Learnings

Building within Stripe's extension sandbox forced creative solutions. No Redux, limited bundle size, restricted APIs. Constraints breed better architecture — the 6-level context system outperformed what Redux would have delivered.
