+# 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
+- no support for the constructor
+  [`options`](https://github.com/websockets/ws/blob/master/doc/ws.md#new-websocketaddress-protocols-options)
+  argument 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:
+
+```js
+const WebSocket = require('isomorphic-ws');
+
+const ws = new WebSocket('wss://echo.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.data} ms`);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now());
+  }, 500);
+};
+```
