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.
