How could I inflate data ,I use Pako.js,php gzdeflate ,client server websocket connect

      websocket.onmessage = function (e) { 
        // var c = new Uint8Array(e.data.arrayBuffer())



    var blob = e.data;
    var reader = new FileReader();
    reader.readAsBinaryString(blob);
    reader.onload = function (evt) {
        console.log(evt.target.result)
      var data = pako.inflate(evt.target.result, { to: `string` })
      
      console.log(JSON.parse(data))
    };

        $data = gzdeflate('asdfsadf11');
        foreach($server->connections as $conn) {
            $server->push($conn, $data,WEBSOCKET_OPCODE_BINARY);
        }
