Frontend API Integration Patterns

Overview

This skill provides production-ready patterns for integrating frontend applications with backend APIs.

Most frontend issues are not caused by APIs being difficult to call, but by incorrect handling of asynchronous behavior—leading to race conditions, stale data, duplicated requests, and poor user experience.

This skill focuses on correctness, resilience, and user experience, not just making API calls work.

When to Use This Skill

• Connecting frontend apps (React, React Native, Vue, etc.) to backend APIs
• Integrating ML/AI endpoints (/predict, /recommend)
• Handling asynchronous data in UI
• Fixing stale data, flickering UI, or duplicate requests
• Designing scalable frontend API layers
