Custom React Components Via Components V2 Api With Bidirectional Communication

Turn Python scripts into web apps — declarative API, data viz, chat components, free hosting.

Unique: BidiComponent pattern with Protocol Buffer serialization enabling real-time bidirectional communication between Python and React, allowing custom components to send and receive data without page reloads. Components v2 provides a TypeScript SDK that abstracts Protocol Buffer complexity.

vs others: More flexible than Components v1 because bidirectional communication enables interactive components; more powerful than st.* functions because developers have full React control; better than Dash custom components because WebSocket communication is built-in.

via “react-component-based-chat-interface”

OpenAI Assistants API quickstart with Next.js.

Unique: Provides a single Chat component that handles all conversation logic (message state, streaming, function calls, rendering) and is reused across all example pages, demonstrating component composition and reducing code duplication

vs others: More maintainable than duplicating chat logic across pages because changes to conversation behavior only need to be made once, and more flexible than a monolithic application because the component can be imported into different contexts
