I finished an application with JS, Mongo Db Atlas, and node Js(express). It works fine locally on my computer.
I am trying to put it online with vercel. I have linked my vercel account to Github. The front end part of my application works fine but every request to the backend don't work...
This is the error message that i get :
Failed to load resource: net::ERR_CONNECTION_REFUSED.
Is there somethin that i am supposed modify in my code when I put it online ?
My request still look like this :
const fetchCardList = () => {
fetch("http://localhost:5000/api/card/")
.then((reponse) => reponse.json())

I recently started working on a project with Express and since I'm using Node.js as backend I chose MongoDB as my database. It's my first time working with Mongo but I can't authenticate with Express, it works fine from terminal. I followed the guide from MogoDB blog here. I tried using their Atlas service where I had no problem authenticating. I'm using MongoDB driver. Here's how my connection URI looks like:
const uri = `mongodb://${username}:${password}#127.0.0.1/cloud?retryWrites=true&w=majority`;
I tried changing mongodb:// to mongodb+srv:// but that resulted in invalid connection string error.
You need to specify the authentication database, usually admin:
const uri = `mongodb://${username}:${password}#127.0.0.1/cloud?authSource=admin&retryWrites=true&w=majority`;
If you don't specify it then in your case MonogDB defaults the authentication database to cloud - which is most likely wrong.
When you are accessing mongodb on the web you can click on connect and on connect your application. You will show the uri to copy paste starting with
mongodb+srv://USERNAME:PASSWORD#CLUSTER/DATABASE
You forgot to specify the CLUSTER. Currently is your local Database

enter image description hereSuccessfully deployed to Heroku and most of our application is working. However, our socket.io pieces (chat, view online users, game updates) are not functioning. We think this may be due to having an instance of socket initialized in the Board.js component and also in the App.js file but not sure if that is the issue or how to resolve.

It looks like you are missing an io.connect statement in your server.js file. Check out this video (https://www.youtube.com/watch?v=y5tRiFJuNOs) along with the source code in the description.
