serverless-websocket

Low-level library to generate WebSocket URLs for serverless applications using AWS IoT and Cognito identity pools. Current stable version is 1.0.1 (last release). Release cadence is unknown; repository appears inactive with no recent commits. Key differentiators: provides a lightweight, minimal way to obtain a WebSocket URL suitable for MQTT over WebSockets, targeting browser and Node.js. Unlike full-service alternatives like Pusher or Ably, it focuses only on AWS IoT connectivity, leaving the MQTT client choice to the user.
