Add firebase cloud function in existing project

Question

I have a project which contains Firebase and already runs. Today I need to add cloud functions inside. But I don't know how to add it in a running project. I didn't find proper documents for my case.

What would happened if I tried init firebase and checked cloud functions only in my current project. Will it delete my previous setup (i have installed Firestore, storage,etc)?

Answer 1

As explained in the Firebase CLI doc, "you can always run firebase init later to set up more Firebase products" after the initial initialization.

So, running it again will not delete your previous setup.

Take care to only select the additional services: as noted in the doc, "If you run firebase init again for any Firebase service, the command will overwrite the corresponding section of the firebase.json file back to the default configuration for that service."
