This explorer reads the filesystem of the server it runs on, so /workspace/user isn't present here. Browsing and the terminal still work against this server's own disk from /.

# isomorphic-ws Isomorphic implementation of WebSocket. It uses:- [ws](https://github.com/websockets/ws) on Node- [global.WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) in browsers ## Limitations Before using this module you should know that[`ws`](https://github.com/websockets/ws/blob/master/doc/ws.md#class-websocket)is not perfectly API compatible with[WebSocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket),you should always test your code against both Node and browsers. Some major differences: - no `Server` implementation in browsers ## Usage You need to install both this package and [ws](https://github.com/websockets/ws): ```> npm i isomorphic-ws ws``` Then just require this package: ```jsconst WebSocket = require('isomorphic-ws') const ws = new WebSocket('wss://echo.websocket.org/', {  origin: 'https://websocket.org'}); ws.onopen = function open() {  console.log('connected');  ws.send(Date.now());}); ws.onclose = function close() {  console.log('disconnected');}); ws.onmessage = function incoming(data) {  console.log(`Roundtrip time: ${Date.now() - data} ms`);   setTimeout(function timeout() {    ws.send(Date.now());  }, 500);});``` ## License [MIT](LICENSE)
