A very common reason is a wrong site baseUrl configuration.\n

Current configured baseUrl = / (default value)\n

We suggest trying baseUrl = \n\n';var e=document.getElementById("__docusaurus-base-url-issue-banner-suggestion-container"),s=window.location.pathname,r="/"===s.substr(-1)?s:s+"/";e.innerHTML=r}}window.__DOCUSAURUS_INSERT_BASEURL_BANNER=!0,document.addEventListener("DOMContentLoaded",maybeInsertBanner)

Socket.IO

Bidirectional and low-latency communication for every platform

Get startedDocumentation

Performant

In most cases, the connection will be established with WebSocket, providing a low-overhead communication channel between the server and the client.

Reliable

Rest assured! In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. And if the connection is lost, the client will automatically try to reconnect.

Scalable

Scale to multiple servers and send events to all connected clients with ease.

Basic example
