# `@libsql/isomorphic-ws` This package provides `WebSocket` on Node (using `ws`) and in Deno and Cloudflare Workers (using the native `WebSocket`). Supports both CommonJS and ES modules. ```javascript import { WebSocket } from "@libsql/isomorphic-ws"; const ws = new WebSocket("ws://localhost:8080"); ws.onopen = (event) => { ws.send("Hello"); }; ws.onmessage = (event) => { console.log(event.data); ws.close(); }; ```
