I'm setting up my dev system to use https, and Chrome is complaining about my websocket not begin secure:
VM4965:161 Mixed Content: The page at 'https://mywebsite.io/' was
loaded over HTTPS, but attempted to connect to the insecure WebSocket
endpoint 'ws://mywebsite.io:4000/subscriptions'. This request has
been blocked; this endpoint must be available over WSS.
Here's my current server-side setup for WS, based on the Apollo docs:
const localHostString = 'mywebsite.io';
const pubsub = new PubSub();
// additional context you use for your resolvers, if any
const context = {connectors: connectors};
//SET UP APOLLO QUERY / MUTATIONS / PUBSUB
//start a graphql server with Express handling a possible Meteor current user
createApolloServer({
schema,
context
});
const METEOR_PORT = 3000;
const GRAPHQL_PORT = 4000;
const server = express();
server.use('*', cors({ origin: `https://${localHostString}:${METEOR_PORT}` }));
server.use('/graphql', bodyParser.json(), graphqlExpress({
schema,
context
}));
server.use('/graphiql', graphiqlExpress({
endpointURL: '/graphql',
subscriptionsEndpoint: `ws://${localHostString}:${GRAPHQL_PORT}/subscriptions`
}));
// Wrap the Express server
const ws = createServer(server);
ws.listen(GRAPHQL_PORT, () => {
console.log(`GraphQL Server is now running on http://${localHostString}:${GRAPHQL_PORT}`);
console.log(`GraphiQL available at http://${localHostString}:${GRAPHQL_PORT}/graphiql`);
// Set up the WebSocket for handling GraphQL subscriptions
new SubscriptionServer({
execute,
subscribe,
schema
}, {
server: ws,
path: '/subscriptions',
});
});
How can I update this so as to use WSS rather than WS websockets?
Thanks in advance to all for any info.
It looks like you're doing
subscriptionsEndpoint: `ws://${localHostString}:${GRAPHQL_PORT}/subscriptions
Maybe instead, change ws to wss. ie:
subscriptionsEndpoint: `wss://${localHostString}:${GRAPHQL_PORT}/subscriptions

I am trying to connect socket.io client which inside react app to the socket.io server but i am getting xhr poll error. I am unable to figure out what is going wrong? client & server code is as follow:
import io from 'socket.io-client';
const socket = io("ws://loacalhost:5000");
socket.on("connect_error", (err) => {
console.log(`connect_error due to ${err.message}`);
});
const express = require('express');
const app = express();
app.use(require('cors')());
const http = require('http');
const server = http.createServer(app);
const io = require("socket.io")(server, {
rejectUnauthorized: false,
cors: {
origin: "http://localhost:3000",
methods: ["GET", "POST"]
}
})
io.on("connection", (socket) => {
console.log(socket.id)
})
server.listen(5000, () => {
console.log('Server is listening on Port 5000');
});
Everything is ok in server file as well as everything is ok in client file except there is syntax mistake in client code i.e.
const socket = io("ws://loacalhost:5000");
replaced with:
const socket = io("ws://localhost:5000");
then it is worked fine, successfully connected to server
Your localhost spelling is incorrect.
const socket = io("ws://loacalhost:5000");
Replaced with
const socket = io("ws://localhost:5000");
I'm creating my product and stuck with this problem. One day I setuped socket.io and everything worked well. On the next day I migrate my server and client from http to https. After the migration client side and server side still connected, but I can't emit from client side to server and from server to client.
Server side
I have my ssl certificate inside ./security/cert.key and ./security/cert.pem they are loading correctly. My server running on https://localhost:5000
import fs from "fs";
import https from "https";
import socketio from "socket.io";
import express from "express";
// HTTPS optiosn
const httpsOptions = {
key: fs.readFileSync("./security/cert.key"),
cert: fs.readFileSync("./security/cert.pem"),
};
// Setup express and https server
const app = express();
const server = https.createServer(httpsOptions, app);
// Setup socket io
const io = socketio.listen(server, {
origins: "https://localhost:3000",
transports: ["websocket"],
});
server.listen(5000, () => {
console.log(`server listening on https://localhost:5000`);
});
io.listen(server);
io.on("connection", (socket) => {
console.log("new socket connected!");
console.log(`data = ${socket.handshake.query.data}`);
socket.emit("some-event");
socket.on("some-event-2", () => console.log("some-event-2 happened!"));
});
Client Side
My example react component. My react app is running on https://localhost:3000. HTTPS is connected and working well.
import React from "react";
import io from "socket.io-client";
const Sandbox: React.FC = () => {
const query = {
"data": 123,
};
const socket = io.connect("https://localhost:5000", {
secure: true,
query,
transports: ["websocket"],
});
socket.on("connect", () => console.log("connect!"));
socket.on("some-event", () => console.log("some event happened"));
socket.emit("some-event-2");
return <React.Fragment />;
};
export default Sandbox;
And now the problem. On client side in console I should see connect! and some event happened
And on server side I should see the messages new socket connected! and data = 123, some-event-2 happened!. But instead my client side console is completely clear
And server side console have only a few logs, but dont contains emit logs
What should I do? Maybe I'm incorrectly using socket.io with https?
I fixed my error.
The problem was that I was firstly create https server and after that only call .listen() on it. listen() - is not a void, it's return another server obj. You need to pass the result of .listen() function inside your io.listen()
// Don't do that❌
var server = https.createServer(options, app);
server.listen(5000);
io.listen(server);
// Do that✅
var server = https.createServer(options, app).listen(5000);
io.listen(server);
I need socket.io instance in several places in my app. To achieve this in express i can do this:
app.set('io', io);
In koa right now i have this:
app.use( async ( ctx, next ) => {
ctx.io = io;
await next();
});
This works, but this middleware executes every time my server recieves request. Is there a better way to do this?
I don't know how you are fully implementing but there are a couple things that you can do is you can either pass an addition argument and upgrade the connection to a websocket that will bypass the rest of the middlewares. Or, what I do personally is just have any websocket connection go to a different end point. This will help with any future scalability issues. for example, if you need to create clusters of your server then you will have more control as well will help you testing your backend easier. That's what I would do atleast. My socket.io back end looks like this:
server.ts
oh yea I'm using typescript in the back end
require('dotenv').config({ path: __dirname + '/.env' });
import Koa from 'koa';
const koa = new Koa();
import cors from '#koa/cors';
const PORT = process.env.CHAT_PORT || 3000;
const ENV = process.env.NODE_ENV || 'development';
const server = require('http').createServer(app, { origins: 'http://server.ip' });
const io = (module.exports.io = require('socket.io')(server));
import SocketManager from './lib/SocketManager';
app.use(
cors({
origin: '*',
optionsSuccessStatus: 200,
}),
);
// server setup
server.listen(PORT, (err: ErrorEvent): void => {
if (err) console.error('❌ Unable to connect the server: ', err);
console.log(`💻 Chat server listening on port ${PORT} - ${ENV} environment`);
});
io.on('connection', SocketManager);
then just create a socket manager that imports the io instance and you can then go ahead and handle all the connections.
I hope this is the answer you were looking for/gave you some better insight.
I'm trying to connect to a local dev environment via an IP address. I'm getting an error because HTTPBatchedNetworkInterface shows:
_uri: "http://10.0.1.10/graphql"
...when it needs to be:
"http://10.0.1.10:3000/graphql"
Here's my server-side setup code:
const localHostString = '10.0.1.10';
const METEOR_PORT = 3000;
const GRAPHQL_PORT = 4000;
const server = express();
server.use('*', cors({ origin: `http://${localHostString}:${METEOR_PORT}` }));
server.use('/graphql', bodyParser.json(), graphqlExpress({
schema,
context
}));
server.use('/graphiql', graphiqlExpress({
endpointURL: '/graphql',
subscriptionsEndpoint: `ws://${localHostString}:${GRAPHQL_PORT}/subscriptions`
}));
// Wrap the Express server
const ws = createServer(server);
ws.listen(GRAPHQL_PORT, () => {
console.log(`GraphQL Server is now running on http://${localHostString}:${GRAPHQL_PORT}`);
console.log(`GraphiQL available at http://${localHostString}:${GRAPHQL_PORT}/graphiql`);
// Set up the WebSocket for handling GraphQL subscriptions
new SubscriptionServer({
execute,
subscribe,
schema
}, {
server: ws,
path: '/subscriptions',
});
});
What is the correct way to get the port number into HTTPBatchedNetworkInterface._uri?
Thanks in advance to all for any info.
Fixed. My framework is Meteor and I had to set ROOT_URL = 10.0.1.10:3000/.
I have the current setup:
Nodejs Proxy (running http-reverse-proxy) running on port 80.
Rails server running on port 3000
Nodejs web server running on port 8888
So any request starting with /nodejs/ will be redirected to nodejs web server on 8888.
Anything else will be redirected to the rails server on port 3000.
Currently Socket.io requires a connection url for io.connect.
Note that /nodejs/socket.io/socket.io.js is valid and returns the required socket.io client js library.
However, I am not able to specify connection_url to /nodejs/ on my server.
I have tried http://myapp.com/nodejs and other variants but I am still getting a 404 error with the following url http://myapp/socket.io/1/?t=1331851089106
Is it possible to tell io.connect to prefix each connection url with /nodejs/ ?
As of Socket.io version 1, resource has been replaced by path. Use :
var socket = io('http://localhost', {path: '/nodejs/socket.io'});
See: http://blog.seafuj.com/migrating-to-socketio-1-0
you can specify resource like this:
var socket = io.connect('http://localhost', {resource: 'nodejs'});
by default resource = "socket.io"
If you are using express with nodejs:
Server side:
var io = require('socket.io')(server, {path: '/octagon/socket.io'});
then
io.on('connection', function(socket) {
console.log('a user connected, id ' + socket.id);
socket.on('disconnect', function() {
console.log('a user disconnected, id ' + socket.id);
})
})
socket.on('publish message ' + clientId, function(msg) {
console.log('got message')
})
Client side:
var socket = io('https://dev.octagon.com:8443', {path: '/octagon/socket.io'})
then
socket.emit('publish message ' + clientId, msg)
I use below approach to achieve this goal:
client side:
var socket = io.connect('http://localhost:8183/?clientId='+clientId,{"force new connection":true});
server side:
var io = require('socket.io').listen(server);
io.sockets.on('connection', function(socket) {
console.log("url"+socket.handshake.url);
clientId=socket.handshake.query.clientId;
console.log("connected clientId:"+clientId);
});

If you are serving your app with express, then maybe you can check this out. Remember express uses http to serve your application.
const express = require('express'),
http = require('http'),
socketIo = require('socket.io'),
app = express()
var server = http.createServer(app);
var io = socketIo(server);
io.on('connection', (socket)=>{
// run your code here
})
server.listen(process.env.PORT, ()=> {
console.log('chat-app inintated succesfully')
})
