Streaming Ollama Responses in Next.js: The SSE Pattern That Actually Works

Streaming Ollama Responses in Next.js: The SSE Pattern That Actually Works Most Next.js + Ollama tutorials show a single await fetch and call it a day. The user types a question, waits eight seconds, and a wall of text appears. That's a bad UX. Real LLM apps stream tokens as they're generated. The user sees a response materialise word by word, just like ChatGPT. This post shows how to build that on Next.js 15 App Router with Ollama as the backend, using Server-Sent Events. Production-ready in under a hundred lines.
