Next.js

Next.js is a React framework for building full-stack web applications with features like server-side rendering (SSR), static site generation (SSG), API routes, and edge functions. It provides file-based routing, automatic code splitting, and built-in optimization for images and fonts. In the AI agent ecosystem, Next.js is commonly used as the frontend framework for building chat interfaces, dashboards, and admin panels that connect to Python/FastAPI AI backends. It handles real-time streaming UI updates via Server-Sent Events or WebSockets.

FastAPI

Frameworks & Tools

FastAPI is a modern, high-performance Python web framework for building APIs, built on top of Starlette (for async HTTP) and Pydantic (for data validation).

Server-Sent Events

Infrastructure

Server-Sent Events (SSE) is a standard HTTP-based protocol for server-to-client streaming, where the server pushes events over a long-lived HTTP connection.

WebSocket Streaming

Infrastructure

WebSocket streaming uses the WebSocket protocol to establish a persistent, full-duplex communication channel between the client and server, enabling real-time bidirectional data flow.
