Hello,

You need a start script in your package.json

I am creating an app with a backend and front end. should I set the start at the .json of the front, back or app (that has both of them?)

Is it a isolated monorepo?

sorry, I'm not sure what you mean. I have without a start->
app/package.json

at my app/backend/package.json

"scripts": {   
 "start": "node ./build/server.js",

and at my app/frontend/package.json

 "scripts": {
    "dev": "vite --open",

Please share your repo.

Do the frontend and backend share packages or libraries?

they dont

You need two Railway services, one for the frontend and one for the backend.

Then in each service settings, set the applicable root directory.

And for the frontend, use the Dockerfile and Caddyfile shown here -

https://docs.railway.app/guides/react#use-a-dockerfile

But in the Caddyfile, replace dist with build
