make sure your app is listening on the PORT provided by Railway
I recommend you check this out:

Thank you, I didn't know about this

And wow that was a quick response lol

no problem 🙂

Fixed, thank you :)

Awesome, I'm happy to help! :D

Just noticed it's still giving me this error and restarting over and over, yet on the domain it seems fine?

Can I just ignore this lol

Mind sending me a screenshot of your memory metrics in your service?

How do I do this?

Not sure what memory metrics are haha

in your service you'll see a Metrics tab

you can click on that to see your application's metrics, it shows info about your app's cpu, memory and network usage

dang your app uses next to no memory, what the flip

Is that a good or a bad thing…

typically a good thing but I feel this may not be intended here

I'm wondering if your app may be trying to allocate more than 500mb of memory quickly after starting up, and if that fails your app exits making it show no memory usage even though it wants to use a ton of memory

So I need to increase the 500mb cap or something?

If I'm right then yes that would be the solution, and you can do that by upgrading to hobby plan ( which increases the cap from 500mb to 8gb )

Although, I'm not 100% certain that this is in fact the issue

I have the frontend hosted on Vercel and it seems to be communicating with the backend correctly though lol

This is strange

oh, maybe it's just an operation in your app that's failing to allocate the required memory instead of your entire app then 🤔

oh well, if it works it works 😆

The backend just crashed so I take that back 😅

oh 💀

then this is still my best guess about what's happening

Do most MERN apps need more than 500mb of memory allocated like this or have I just wrote bad code or something lol

wait one last idea, could you try setting a NODE_OPTIONS service variable to --max-old-space-size=8192

Haha well the error changed

Now it just says "Killed"

And restarts over and over

After doing this

it largely depends on your app itself, like how big of a userbase it has and what specifically goes on inside of it, I use a similar stack and my apps use around 100mb to 300mb depending on the scale

okay definitally a step in the wrong direction then 🤣

I'm gonna go ahead and lock in on this then

Feel free to wait for a second opinion though

Maybe someone else has an idea

I also get a CORS error now interestingly

I'll try upgrading to Hobby plan

Sounds good, hopefully that does solve your issue

Nice I get a $5 discount anyway so it's basically free

Yeah… I've been trying to host my website for 2 days now and I can confidently say it's the worst part of webdev 😭

lmao, fr

Railway's mission is to make it the easiest part of web dev 🚀

Damn it

It seemed like it was fixed then it just sent the error again haha

Darn, that's unfortunate

Bit of a bigger error this time, looks mostly similar though

It restarts every minute or so now instead of immediately like last time

so it runs for about a minute before crashing?

Yeah lol

The Railway deployment doesn't crash

It just restarts it every minute

I wouldn't recommend using nodemon in production

nodemon is strictly meant for development

Nice to know, I'll try fixing that now lol

Honestly the first 2 days I tried doing this I didn't even know the frontend and backend were meant to be deployed separately LOL

So just node instead?

exactly

Seems to be working now, API calls do feel noticeably slower now that I'm not using [localhost](localhost), is this normal?

yea, when you're testing locally then your apps are in the same machine and so requests are practically instant as opposed to running in development where the server is usually in a server far away from the client computer

your deployment is running in US-west, so if you're far away from western US then API calls will be significantly slower

Ah okay, thank you for all your help :)

This whole experience was just depressing lol, time to go do fun things with my life again

lmao, enjoy!

of course, any time <:SmileFluent:865334941150871592>
