A standalone build of socket.io-client is exposed automatically by the
socket.io server as /socket.io/socket.io.js. Alternatively you can
serve the file socket.io.js found in the dist folder or include it via CDN.
<scriptsrc="/socket.io/socket.io.js"></script><script>varsocket=io('http://localhost');socket.on('connect',function(){});socket.on('event',function(data){});socket.on('disconnect',function(){});</script>// with ES6 importimportiofrom'socket.io-client';constsocket=io('http://localhost');A slim build (without JSON3, a JSON polyfill for IE6/IE7, and debug) is also available: socket.io.slim.js.
Socket.IO is compatible with browserify and webpack (see example there).
Add socket.io-client to your package.json and then:
varsocket=require('socket.io-client')('http://localhost');socket.on('connect',function(){});socket.on('event',function(data){});socket.on('disconnect',function(){});See API
