I am using ioRedis coupled with express-session in my NodeJS app and I'd like to fire an event when a session expires. I wrote this:
let Redis = require('ioredis');
let clientRedis = new Redis();
let RedisStore = require('connect-redis')(session);
const sessionMiddleware = session({
store: new RedisStore({
client: clientRedis,
}),
secret: SESSIONSECRET,
resave: true,
saveUninitialized: true,
cookie: {
maxAge: 5000,
secure: false,
httpOnly: true,
domain: config.get('app.domainecookie')
}
});
app.use(sessionMiddleware);
I read the doc and I have no clue on how capture the "expire" event... There must be a ioredis function, but I don't see which one.
I read a lot of questions talking about key expiration but this is not a particular key I want to get the notifications of, I want the session of the user to get a notification (I'm handling the messages with a socket which works like a charm, I just don't know how to capture the event).
For the moment I created an express middleware firing timed out functions in a custom "activeSessions" object, but this is using memory of my NodeJS.app, there must be a better way to do this.
Thanks in advance :)

I know this question is redundant, but I have been searching and reading articles all around for hours now. I am using express-session to control user sessions for the express server. It works when I try to console req.session.user from a postman request. When I try to fire the same request from the browser, it returns undefined. Everyone is talking about Chrome security updates and third-party cookies restrictions. I've tried to stick to chrome guidelines on cookie options but didn't help. If I deployed my client or server to a secure domain would it help?
Here are my options
app.use(cors())
app.set('trust proxy', 1) // trust first proxy
app.use(session({
store: new (require('connect-pg-simple')(session))({pool}),
secret: process.env.SESSION_SECRET,
resave: true,
rolling: true,
cookie: {
maxAge: 30 * 60 * 1000, // 30 minutes
secure: false,
sameSite: 'none'
},
saveUninitialized: false,
}));
I'm trying to create a guest account for a portfolio website so that recruiters can play with it without having to register and set things up, but I need the account to be session or IP specific so that users can have their own guest account without interfering with each other.
I thought about achieving that by using the sessionID within ApolloServer's context.req as the account name but I've noticed I get a different sessionID on every request/refresh.
My backend's session setup looks like this:
const app = express();
// Initialize redis sessions server
const redisConfig = app.get('env') === 'production' ? { host: 'redis' } : undefined; // Change host from default to the name of the docker service (redis) when in production
const RedisStore = connectRedis(session);
const redisClient = redis.createClient(redisConfig); // This would take the connection parameters, but we leave the default values: https://redislabs.com/lp/node-js-redis/
// Tell express that we have a proxy in front of our app so that sessions work when using Nginx: http://expressjs.com/en/guide/behind-proxies.html#express-behind-proxies
if (app.get('env') === 'production') app.set("trust proxy", 1);
app.use(
cors({
origin: process.env.CORS_ORIGIN,
credentials: true
})
);
app.use(
session({
name: COOKIE_NAME,
store: new RedisStore({
client: redisClient,
disableTTL: true, // TTL: time to live, how long the session is active, if we want our sessions to be active permanently until manually disabled.
disableTouch: true, // Prevent that the TTL is reset every time a user interacts with the server.
}),
cookie: {
maxAge: 10 * 365 * 24 * 60 * 60 * 1000, // How long in miliseconds until the cookie expires (10 years)
httpOnly: app.get('env') === 'production', // Prevents JS in the frontend from accessing the cookie.
// domain: app.get('env') === 'production' ? 'websitename.com' : undefined,
secure: app.get('env') === 'production', // Cookie only works in https
sameSite: 'lax',
},
saveUninitialized: false, // Prevents that empty sessions are created.
secret: `${process.env.SECRET}`,
resave: false, // False to prevent constant pinging to Redis
})
);
And in my frontend:
const client = new ApolloClient({
cache: new InMemoryCache(),
link: new HttpLink({
uri: process.env.API_URL,
credentials: 'include', // Required for sessions. Sends our cookie back to the server with every request.
})
});
This happens both in my local dev environment and in my deployed https website. I've seen similar issues with suggestions about changing the secure and samesite parameters or the CORS config, but that hasn't worked for me so far.
Any idea of what the issue might be? Is this just not the right approach to do what I'm after?
Sorry if it's something super-obvious, haven't touched my server in months and my backend skills are a bit rusty '^^.
I've looked through quite a few issues on this and have tried every combination of "solutions" for my problem but can't seem to figure this one out.
I currently have a client side react application being hosted on azure. Let's call this https://clientside.net for short.
I also have a server side node js application being hosted on azure we'll call this https://serverside.net.
I can't seem to to get the session variables to save upon authenticating users. This works perfectly fine on localhost btw.
e.g. On the client side we are making requests using axios like so:
const headers = {
withCredentials: true,
headers: { auth: process.env.REACT_APP_SECRET },
};
axios.get(`${process.env.REACT_APP_SERVER}/get/auth`, headers).then((response) => console.log("blah blah blah"));
On the server side this is how express session is setup...
app.use(
cors({
origin: ["https://clientside.net"],
methods: ["GET", "POST"],
credentials: true,
})
);
app.set("trust proxy", 1);
app.use(
session({
name: "sid",
saveUninitialized: false,
resave: false,
secret: "shhh",
cookie: {
domain: ".clientside.net",
maxAge: 1000 * 60 * 60 * 8,
secure: true,
httpOnly: false,
},
})
);
Within our authentication route on server side we are saving session like so ...
req.session.username = req.body.username;
req.session.password = req.body.password;
req.session.save(() =>
res
.status(202)
.json({
authenticated: true, username: req.session.username})
);
Upon refreshing or attempting to hit any other routes, the req.session.username & req.session.password are nowhere to be found. Is there something wrong with my session config? Or am I perhaps missing something? I appreciate any and all help on this! Thanks y'all
I've figure out the issue.
Deploying an application using azure app services, means you will be using a reverse proxy.
In my case nodeiis web service proxy.
The client side makes requests to the iis service which then routes the request to the node server.
I made many changes but the one that got me up and running was switching the cors origin and session domain to be the server side domain/ip like so...
app.use(
cors({
origin: ["https://serverside.net"],
methods: ["GET", "POST"],
credentials: true,
})
);
app.set("trust proxy", 1);
app.use(
session({
name: "sid",
saveUninitialized: false,
resave: false,
secret: "shhh",
cookie: {
domain: ".serverside.net",
maxAge: 1000 * 60 * 60 * 8,
secure: true,
httpOnly: false,
},
})
);
Now session variables are able to be successfully saved upon login.
I have a simple requirement to store an access token/refresh token in Express (without using localStorage or anything). I'd like to store them in a persistent httpOnly cookie so any time a user visits the page who has previously visited the page can see if the access token is already there, and if so, make API calls and log in and so on.
I've spend some time looking at express-session and cookie-session and simply can't figure out the proper way to do it. express-session requires a store for production, and I don't want to set up a store to simply store an access token. So something like this works in devleopment:
app.use(
session({
secret: 'conduit',
cookie: {
path: '/',
maxAge: 60 * 60 * 1000,
httpOnly: true,
secure: isProduction,
},
resave: false,
saveUninitialized: false,
})
)
Using this to set it on request:
request.session.accessToken = accessToken
request.session.save()
But if it's not going to work in a production environment, it's not helpful. I haven't been able to get it working with cookie-session, or I don't know how to set/retrieve the cookies, and the documentation isn't very helpful.
So I'm asking: how can I store a few strings on an Express server/httpOnly cookie in a persistent way, without using a Store/Redis/MemCache/etc?
I had to use cookieParser.
const cookieParser = require('cookie-parser')
app.use(cookieParser())
// set a cookie
response.cookie('nameOfCookie', 'cookieValue', {
maxAge: 60 * 60 * 1000, // 1 hour
httpOnly: true,
secure: isProduction,
})
// get a cookie
request.cookies.nameOfCookie
// destroy cookie
response.clearCookie('nameOfCookie')
In Expressjs, i have some code to use cookie session, which is a middleware that is like express-session, but it keeps the session even after the server restarts. I was looking at other questions, but they all said that you should add a maxAge attr to the cookie. I did this, and the session still expires after the browser closes. Here:
const express = require('express');
const app = express();
const session = require('cookie-session');
app.use(session({
name: 'session',
secret: `secret`,
httpOnly: true,
expires: new Date(Date.now() + 999999999999999999999999999999999999999999999999999999999999999999999999999*9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999*999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999),
maxAge: 999999999999999999999999999999999999999999999999999999999999999999999999999*9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999*999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999,
signed: true
}));
This is was shown in other questions, (besides the expires and maxAge being very long). So, what is my problem? Again, i would like to make the session last even after the window closes, right now it lasts after the tab closes but not the entire window. This only needs to work in Chrome. Thanks!
You can try:
app.use(session({
secret: "session",
resave: true,
resave: false,
saveUninitialized: true,
key: 'express.sid'
}));
Otherwise, I would save the cookie to database, and always compare user's cookie with cookies in db.
P.S.
Note If both expires and maxAge are set in the options, then the last one defined in the object is what is used.
