That post covered one specific piece: pulling the <code>response</code> field out of a half-received JSON object so users see text immediately.</p> <p>But that parser lives inside a larger system. There&rsquo;s a server emitting tokens over SSE, a chunk protocol that handles tool execution mid-response, a transport layer that works on React Native (barely), and a rendering pipeline that switches from plain text to rich content when the stream completes. The parser was the fun bit to write about. The pipeline around it is where the real engineering decisions live.</p>
