Can i create simple chat app where e.g. client.html is on my localhost server, and server.js is uploaded on nodester.com and running online (using socket.io)?
For example, how can I adapt the simple chat code in this question for working in the way described above (server.js on some server online and client.html on my localhost)?
Absolutely. Have a chat application running on AWS and the chat client running on localhost. Presume it should be possible with the others too.

I'm currently working on a game that connects to a Node.js server for multiplayer data.
The game is developed in Unreal Engine 4 and uses the Socket.io plugin to connect to the Node.js server (cors, express being used).
Everything works locally. So now I'm trying to move on to hosting the server remotely and connecting the unreal client to the remote Node.js server.
I looked into Heroku and set myself up, everything is working fine on its end to my knowledge - I created a tester page with a success message when you load the URL and that comes through.
My first question is - what am I doing wrong when I use unreal to point the socket.io plugin to the server url?
The socket.io plugin asks for a port #, I've tried the following:
http:/{my server/heroku url}:8080/
http:/{my server/heroku url}:3000/
http:/{my server/heroku url}:18279/ (which was given to me by Heroku).
http:/{my server/heroku url}/
So far the game does not connect to the deployed server, the way it does locally.
Any suggestions on what could be going wrong/what am I failing to do next?
A few things after researching:
I do have http-session-affinity enabled
Since the server is working locally, I'm going to make the assumption that the deployed code is not the issue, and that it has to do with the way I'm trying to connect.
is it possible that I have further authorization to config? Such as allowing the unreal game/client to connect to the server/that the client is being blocked some how?
I figured out the issue, it had to do with how my Node.js server code was calling socket.io.
If you come across this issue please send me a message or comment here and I will be happy to send you the code that worked.
I created a small server using socket.io and node js and deployed in heroku earlier. I was easily able to have client connected to server with wss/ws protocol but when I deployed my app too AWS, Clients are not connecting. I debugged the application in client side but Its just not connecting to server. Did I miss something? are there extra steps needs to followed to make it work?
Thanks.
Answering my own question, I had to add .ebextensions folder with a config in my project root directory. You can look at the following tutorial to make it work https://nikhilmopidevi.github.io/2017/10/18/WebSockets-with-AWS-Elastic-Beanstalk/
I try to make a client-server app with socket.io.
Socket.io server seems work but the client cannot connect to it. The error i get is about the '/socket.io/socket.io.js' like what it is unable to load it.
So here are my questions
is it mandatory to have server and client in the same folder as we can see in the official demo ?
can we make a nodejs socket.io server without express ?
Depending on how your project is setup, you need to create 2 server files, 1 for the app, and one for the websockets, and every time a user opens the app it should open(and be told where to try and open the connection) a connection to the websockets server. On my websockets apps I have the app running on localhost:3000, and websockets server on localhost:3001 (and tell the app to look for a server on 3001), so really you don't need to have the server files in the same folder, they can be in 2 opposite ends of your computer, as long as the app points to the server, then your fine, once a connection has been opened, the websocket server will see the client, and it should work! Let me know if that make sense.
No, you can download socket.io front-end lib from another sources, for example cdn. Be sure you installed the right version.
Yes, you can make it without express. Express is just another option for creating an socket.io server.
For example, currently in my project that is written in another back-end node framework i'm using the code below to establish the socket.io server.
const io = require("socket.io")(2337);
io.on("connection", socket =>
// some code
)
I fixed the problem of websocket communication between my server and my client.
After inspected my html client file, i saw on the console this error message 'ReferenceError: io is not defined'.
I google that error and i found this.
Currently I am developing a mobile application with ionic 2. Within the application I got chat functionality. The chat functionality is based on Socket io in a NodeJS API. Unfortunality, it is hard to configure the socket io on Google Cloud App Engine. On my local machine it works fine.
Steps I have undertook:
use port 65080 (and open the firewall port)
2 servers (api calls via 8080 and socket io via 65080
Sample
Does anybody have a solution? Thank you in advance!

Sadly, neither socket.io or Websockets currently work on App Engine. This is something we're actively trying to address:
https://cloud.google.com/appengine/docs/flexible/nodejs/how-requests-are-handled#not_supported
This question is almost identical to this one, and there's some new good news:
GAE support for persistent socket connections arrived in February 2019!
To make this work, you'll need to be using the flex environment and modify your app.yaml to include session_affinity.
I have created a chat application using node.js, socket.io and mongodb and hosted it on a server.
Now I want to use that chat application on different website by taking a link or code and embed it in normal website that is hosted in another server that uses apache.
