How to deploy functions from other directory than '/functions'?

问题

David in his repo:

https://github.com/davideast/react-ssr-firebase-hosting

has the file with firebase functions index.js in the main root, not in the /functions directory.

However, if I do the same and drop my index.js file to main root, if I do firebase deploy --only functions it says in the console:

i  deploying functions

Error: functions\index.js does not exist, can't deploy Firebase Functions

Q: How is it possible that he made it work? How can I do the same and deploy successfully functions from other dir than /functions?

Thanks

firebase.json

{
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "**",
        "function": "ssrapp"
      }
    ]
  },
  "functions": {
     "source": "/"
  }
}

回答1:

The project workspace that you create with the Firebase CLI contains a file called firebase.json that has a stanza for Cloud Functions that looks like this:

"functions": {
  "predeploy": [
    "npm --prefix $RESOURCE_DIR run lint"
  ],
  "source": "functions"
}

That "source" property defines the name of the folder that contains the code that will run on Cloud Functions. You can change that to whatever you want.

If you want to use your root directory as your functions folder just change your source key to . in your firebase.json.

  "functions": {
    "source": ".",
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint",
      "npm --prefix \"$RESOURCE_DIR\" run build"
    ]
  }

This will look for your index.js file in the root directory (remember to move all the other files to your root directory too).
