Sim SDK Web

Sim SDK Web is a JavaScript/TypeScript SDK for integrating real-time instant messaging into web applications. It supports both SSE and WebSocket protocols, allowing developers to build chat features with flexible transport options. Current stable version is 1.2.30, released as needed. Key differentiators: dual protocol support (SSE and WebSocket) and TypeScript type definitions included. Compared to alternatives like Socket.IO, it is lighter and more focused on IM scenarios.
