Large package when deploying

Firebase creates a 38 MB package when I try to deploy my functions. Usually, my functions have less than 1 mb.

Curiously, node_modules has exactly 38 MB, however it is supposed to be automatically ignored (https://stackoverflow.com/a/51182549/6696558).

Is this normal when using this package? Is there any configuration I can do to exclude unwanted parts?

The culprit appears to be the .dart_tools and packages directories, which aren't necessary at runtime. Here's what I did to fix it:

• Removed the build from predeploy in package.json
• Added the following to firebase.json:

"functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run build",
      "npm --prefix \"$RESOURCE_DIR\" run cleanSymlink"
    ],
    "ignore": ["node_modules", ".dart_tool", "packages"]
  },

• Added the following to package.json

{
  "scripts": {
    "build": "pub run build_runner build --output=build",
    "cleanSymLink": "rimraf ./build/node/packages",
    ...
  },
  ...
  "devDependencies": {
    "rimraf" : "^3.0.0",
    ...
  }
}

Re-run npm install in the functions directory and it should work. Cut mine down from 36MB for the sample Hello World to 97KB while the function still works.

Good finding! I was able to reduce to 100kb. But I wanted to add one more thing - on this page https://console.cloud.google.com/ you can download the files that have been deployed to firebase:

That helped me understand what the ignore is actually doing / what still had to be added to the ignore in my case.
