There is an error in client-ios.js, but I don't know where to fix it.
It seems to be an error with the symbol <, but I don't use it anywhere, so it's refreshing.
If you are familiar with javascript, please let me know

I created it by referring to the site, but I don't know how to solve it
Source code for the project created using the above URL
client.js
$(function(){
var socket = newio.Socket(null, {port:8080});
socket.connect();
function iosHandleOrientation(event){
variableData=event.accelerationIncludingGravity;
socket.send(orientData.x+"+orientData.y+"+orientData.z);
}
window.addEventListener("devicemotion",iosHandleOrientation, true);
socket.on('message', function(obj){
data=obj.split("";
$('#data') .append("<tr><td>"+parseFloat(data[0]).toFixed(3)+"</td><td>"+parseFloat(data[1]).toFixed(3)+"<td>td>2Float;"
});
});
server.js
varfs=require('fs');
var http=require('http'),
io= require ('socket.io'),
server = http.createServer(function(req,res){
fs.readFile('./socket.html', 'utf-8', doRead);
function doReard(err,data){
res.writeHead(200, {'Content-Type':'text/html'});
res.write(data);
res.end();
}
});
server.listen (8080);
var socket =io.listen(server);
socket.on('connection', function(client){
client.on('message', function(message){
client.broadcast(message);
console.log(message);
});
client.on('disconnect', function(){
console.log('Connection closed.');
});
});

As you pointed out, I rewritten the server.js and socket.html codes, but I got the following error
TypeError: server.use is not a function
server.js
var express=require('express');
var http=require('http');
io=require('socket.io');
var server = express();
server = http.createServer(function(req,res){
server.use(express.static(__dirname+'/public'));
//fs.readFile('./socket.html', 'utf-8', doRead);
function doReard(err,data){
res.writeHead(200, {'Content-Type':'text/html'});
res.write(data);
res.end();
}
});
server.listen (8080);
var socket =io.listen(server);
socket.on('connection', function(client){
client.on('message', function(message){
client.broadcast(message);
console.log(message);
});
client.on('disconnect', function(){
console.log('Connection closed.');
});
});

I'm sorry to keep bothering you, but if you know anything about it, please take care of me
javascript html node.js iphone socket.io
(This answer was originally posted on Duplicate destination question, but I also posted it here because it was closed as a duplicate.)
This may be because server.js returns socket.html regardless of the path of the request.
The browser looks at the tag <script src="client.js">/script> and requests to the server, but I think the error occurred because it was returned by html.
Use Express for ease of routing.

Does it not match this?
You don't need the tags when in an external.js file.Use these tags to embedded a script inside HTML only.
The answer is
in Japanese.
"External JS files do not require tags.Tags are only required when embedding scripts in HTML."
That's right.
