Stop Making Listeners Wait for the Whole File — Wiring Gemini TTS Streaming into Your Delivery Path
gemini-3.1-flash-tts-preview now streams audio via streamGenerateContent. A delivery path with 1.8s to first sound, covering PCM boundary handling, sentence-level resume, and a fallback for preview shutdown.
Gemini API × TypeScript Type-Safe AI Application Architecture — Integrating Zod Schemas, Structured Output, and Streaming
Type-safe AI applications with the Gemini API and TypeScript: Zod validation, Structured Output, streaming pipelines, and error handling that holds up in production.
Your Gemini API Average Latency Looks Great — But Some Users Still Get Stuck. Defending p95/p99
Your average TTFT is fast, yet a fraction of users keep hitting frozen responses. That is a tail-latency problem (p95/p99). From measurement to model routing, streaming budgets, cache accounting, and retry design — here are the defenses that actually held up in production, with code.
A Lightweight Gemini Backend with Bun and Hono — Reclaiming the Small Tools of Indie Development
Has your Node and Express Gemini backend grown heavy with dependencies and build times? Here is how I moved one to Bun and Hono — folding streaming, rate limiting, cost caps, testing, and self-hosting into a single light runtime — along with the pitfalls I hit in production.
Replaying Gemini API Calls Locally with msw and HTTP Fixtures — How I Cut API Quota Across Six Sites with a Record/Replay Pattern
When you hit the real Gemini API every time you tweak a piece of UI, you end up paying for hundreds of duplicate calls a day. After moving six of my sites to an msw-based record/replay pattern, monthly Gemini billing went unexpectedly quiet. Here's the implementation and operating policy.
Why Gemini API Streaming Drops on iOS After Backgrounding — and How to Fix It
When your iOS app receives a streaming response from Gemini API and the user briefly switches to another app, the stream often goes silent forever. Here's how URLSession actually treats long-lived HTTP, and the smallest change that brings reliability back.
When Gemini API Streaming Cuts Off Mid-Response in Production: The Diagnosis Order I Run
How I diagnose mid-response cutoffs in Gemini API streaming - the order I check network, SDK, and server-side suspects, with real cases from indie production.
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.
When Gemini API Returns Mojibake: 4 Places to Check First
Mojibake in Gemini API responses almost never comes from the API itself — it lives in your client code. Walk through the four layers (HTTP decoding, streaming chunks, output encoding, surrogate pairs) where the corruption hides.
Mastering Gemini API Streaming Responses — Chunk Processing, Error Recovery, and UX Optimization
A production-grade guide to implementing Gemini API streaming responses. Covers chunk parsing internals, automatic recovery from disconnections, and rendering strategies that create a polished user experience.
