ws (Postman Fork)

Postman's fork of the ws WebSocket library for Node.js. Version 7.4.5-postman.1 provides a simple to use, blazing fast, and thoroughly tested WebSocket client and server implementation. It passes the Autobahn test suite and supports HyBi drafts 07-17, permessage-deflate compression, and binary data. Notable differences from the original ws: maintained by Postman for internal use, includes potential patches or compatibility fixes. Release cadence follows upstream ws development. Key differentiator: same API as ws but with Postman-specific modifications. Requires Node.js >=8.3.0, optional dependencies bufferutil and utf-8-validate for performance.
