How to uninstall Firebase functions emulator after installing it with "firebase init"

Question

I installed the Firebase Functions and Firestore emulators in my project with firebase init > emulators but now realize I don't need the Functions emulator any more so I'm trying to delete it.

How can I uninstall an emulator so that the firebase emulators:start command doesn't try to start it by default?

I tried the following but firebase init > emulators continues to show that the functions emulator is still enabled (green dot) and firebase emulators:start continues to start the functions emulator by default if I don't include the --only firestore flag.

I reran firebase init > emulators and deselected functions
- This didn't do anything

I manually removed the entry from firebase.json

"emulators": {
  "functions": { // <-- I removed this block
    "port": 5001
  },
  "firestore": {
    "port": 8080
  },
  "ui": {
    "enabled": true
  }
}

I cleared the emulator cache from ~/.cache/firebase/emulators

I removed the functions block from firebase.json just to see if that was triggering it.

{
  "functions": { // <-- I removed this block
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run clean",
      "npm --prefix \"$RESOURCE_DIR\" run lint",
      "npm --prefix \"$RESOURCE_DIR\" run build"
    ],
    "source": "functions"
  },
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "emulators": {
    "firestore": {
      "port": 8080
    },
    "ui": {
      "enabled": true
    }
  }
}

After doing all of the above, firebase emulators:start still tries to start functions. I wondered if it might be because the firestore emulator depends on the functions emulator but if that were the case I don't know why it would let me run the firestore emulator alone with --only firestore

In my case, I deleted the Function directory from node_modules and I removed the functions block from firebase.json too.

I fixed it just running npm install firebase again.

Removing a service from `firebase.json` did the trick for me. – Pavel Schoffer Oct 28 '22 at 12:58
Reinstalling firebase cli was not necessary for me. Removing from firebase.json and deleting the functions folder was enough. – cybergen Jan 26 '23 at 11:15

If you don't want to use Cloud Functions in your project, you should remove the "functions" folder from your project directory as well.

Also, suggest that you file a bug for this on the firebase-tools GitHub. The fact that the functions emulator runs without configuration in firebase.json feels like a bug, and it didn't used to work that way.

Thanks I filed a bug. I do want to use functions, just don't need to run the functions emulator – geg Dec 17 '20 at 23:24
