When you create your volume, you set a mount path, such as /app/public/uploads <- your application lives inside the /app folder in the container. Then, in your code, anytime you upload a file, or retrieve a file, you would use the environment variable RAILWAY_VOLUME_MOUNT_PATH instead of hardcoding or setting another location. This will point directly to the mount path that you set when creating the volume

so, if I have uploads folder in public/uploads i have to mount my volume in /public/uploads and in the code: in my env files RAILWAY_VOLUME_MOUNT_PATH : (to be set to what?) and use this as folder

You don't have to set RAILWAY_VOLUME_MOUNT_PATH, it is set by default for you. If you are using node, you would use process.env.RAILWAY_VOLUME_MOUNT_PATH in your code and it will point to your public/uploads folder

You don't. You do not need to create that env variable. Railway injects it into your container for you.

so, its like this: file.mv(${process.env.RAILWAY_VOLUME_MOUNT_PATH}/${fileName}) and the env will be taken from the variables, correct? i have read it, but was not getting it, how to proceed ahead

DO NOT ADD THEM IN VARIABLES They are automatically injected to your project on deploy.

mount it to /app/storage and as vin has said three times, do not set them yourself then once you mount to the mount point I gave, I think this code will work

ok i added the changes for mouting, and added the changes in code for that env old: file.mv(./public/uploads/${fileName}) new: file.mv(${process.env.RAILWAY_VOLUME_MOUNT_PATH}/${fileName}) but its not working, now the file itself is not showing when uploaded Sorry to ask such basic questions but I am new to this

Because now they should be uploaded to your volume... upload a bunch of files and see if the storage usage increases. Then you need to update where you read the file to use the same ${process.env.RAILWAY_VOLUME_MOUNT_PATH}/${fileName}

My frontend is hosted in Vercel, wont the env fail?

writing to the volume has to be done by the railway service the volume is attached to what libraries are you using to handle file uploads on the backend
Dheeraj
Dheeraj12mo ago
ok we are not using any library to handle file uploads in backend
