Building an AI Chat App with Expo and Gemini API: From First Commit to App Store Approval
An implementation record of shipping an Expo + Gemini API chat app through both store reviews — measured streaming latency, the chunk-boundary JSON bug, image payload limits, cost ceilings, and the pre-release checklist I run.
Why Is My Gemini API Response Slow? A Practical Diagnosis Guide
Slow Gemini API responses and timeout errors can stem from 4 different causes. This guide walks you through diagnosing each one and applying targeted fixes that actually work.
Production Streaming UI with Gemini API + TanStack Query — Cancellation, Retries, and Cache Coherence
TanStack Query is optimized for one-shot REST/JSON requests, so streaming responses don't fit naturally. This guide walks through the gotchas of using Gemini API SSE with TanStack Query and the production-grade design patterns that hold up in real apps.
Cancelling Gemini API Streams the Right Way — AbortController, asyncio, and the User-Initiated Stop Button
Hitting your chat UI's stop button shouldn't just freeze the screen — it should also stop billing. This guide shows how to wire up AbortController, request.is_disconnected, and the buffered-history pattern so cancellation actually does what users expect.
