How do I ensure that using `gcloud app deploy` is using my build folder not my dev files?

Question

I am new to google app engine. I have a react app

Before deploying to production I use npm run build which creates / updated the build folder. Then I push my app to app engine using gcloud app deploy.

How do I know that the server is using the files in my build folder?

Is there something I should specify in my app.yaml?

Thank you!

You could create an NPM script to first change into the desired build directory when deploying the App Engine app.

package.json

"scripts": {
  "app.deploy": "cd dist/app/ && gcloud app deploy app.yaml --project api-project-########## --version v2 --no-promote --verbosity debug"
   ...
}

Run the script:

npm run app.deploy
