Are you committing your node_modules folder to GitHub?

Yes, my node_modules folder is on Github

The node_modules folder should never be in your repo, remove it and then make sure to add it to your .gitignore

Ok it seems to be running now. Im trying to deploy this server for a website deployed on Vercel, it was made with Vite. The code of this server fetches information from our MongoDB database but when I have running this service and I open the website with the Vercel URL the data is still not shown

What do you see if you visit the domain for your Railway service in your browser?

Where can I find the domain?

In the service settings.

I get a white page with Cannot GET /

I also tried deploying the FrontEnd part of my website and th deploy logs it says that is running on localhost:/5173 but if I enter the Domain of that service i get application failed to respond

That's completely normal for an API.

That's because you are trying to deploy a development server onto Railway, you would need additional configurations in order to properly deploy front ends to Railway.

You need to have your frontend call the backend domain that Railway has provided for your API.

And can I use Vercel for the FrontEnd and Railway for the backend?

Yes, lots of people do that.

Do you mind giving a look to my repositories to see what can I do to connect the frontEnd with the backend? I'm pretty new to deploying stuff so idk which should be the changes that I need to do

That particular question wouldn't really have anything to do with deployments, Your frontend code simply needs to make the fetch requests to the domain Railway has provided you for your API.

I think I sort it out. Thank you so much!

Happy to help!
