Week 19: Full-Stack AI Chatbot Web Architecture & Generative UI

1. Executive Overview

An AI Engineer who only understands the Python backend is blind to the user experience. In production, your model output must be consumed by web browsers, desktop apps, and internal SRE control planes. Week 19 covers the complete Full-Stack AI UI Architecture:

  1. Frontend Streaming Consumption: Consuming ReadableStream / EventSource in the browser, parsing SSE chunks in real time, and auto-scrolling to user focus.
  2. Generative UI & Agentic Component Cards: Beyond plain text, rendering interactive widgets: live "Thinking..." accordions, tool execution badges, interactive runbook citation drawers, and Human-in-the-Loop (HITL) Approve / Reject buttons.
  3. Multimodal Payloads: Uploading architecture PNG diagrams and raw server log dumps, validating MIME types, and compiling base64/URL vision inputs for multimodal LLMs.
  4. Admin & Observability Dashboards: Real-time token spend gauges, cache hit ratio bar charts, and p50/p95 latency sparklines.
  5. E2E Contract Testing: Validating frontend/backend contracts to guarantee zero UI rendering crashes when streaming novel token shapes.
