How I migrated my Stacks Exchange AMM from a monolithic structure to clean separation with automated contract synchronization How I migrated my Stacks Exchange AMM from a monolithic structure to clean separation with automated contract synchronization Introduction Building decentralized applications often starts with everything bundled together. As projects grow and integrate into larger ecosystems, you need clean separation of concerns. This guide covers how I separated my Stacks Exchange AMM frontend from its backend, integrated it into the Pasifika Web3 Tech Hub ecosystem, and created automated contract address synchronization. Note: This project was originally forked from LearnWeb3DAO/stacks-amm to be extended for Pacific Island communities.

} Contract Address Synchronization The Key Innovation: Automated script to sync contract addresses from backend deployments to frontend. The Key Innovation How It Works Reads Clarinet deployment YAML files

Generates TypeScript definitions for frontend

# Test frontend integration
npm run dev Results and Benefits What I Achieved Clean Separation: Frontend and backend are now properly separated
Automated Sync: Contract addresses update automatically
Theme Integration: Seamless Pasifika branding
Type Safety: Full TypeScript support for contract addresses
Production Ready: Zero ESLint warnings, optimized performance
Scalable Architecture: Easy to add new contracts and features Clean Separation: Frontend and backend are now properly separated Clean Separation Automated Sync: Contract addresses update automatically Automated Sync Theme Integration: Seamless Pasifika branding Theme Integration Type Safety: Full TypeScript support for contract addresses Type Safety Production Ready: Zero ESLint warnings, optimized performance Production Ready Scalable Architecture: Easy to add new contracts and features Scalable Architecture Conclusion Separating your DApp frontend from the backend is crucial for scalability, maintainability, and team collaboration. By implementing automated contract address synchronization, you ensure that your frontend always stays in sync with your latest contract deployments. The approach I've outlined here provides: Clean architecture with proper separation of concerns
Automated tooling to reduce manual work and errors
Type safety for better developer experience
Scalable patterns that grow with your project Clean architecture with proper separation of concerns Clean architecture Automated tooling to reduce manual work and errors Automated tooling Type safety for better developer experience Type safety Scalable patterns that grow with your project Scalable patterns Resources Live Demo: Pasifika Stacks Exchange AMM
