Firebase functions saving JSON to local file

Question

I have a firebase functions where I create a JSON:

var tempJSONObject = {
  testing: "why are we testing",
  anothertest:"constanttesting"
}

and I have a temp file:

 const tempFilePath = path.join(os.tmpdir(), data.jokeid);

how do I save my JSON to this temporary file,so I can upload the file to firebase storage? I have to do this since when I pass the JSON directly to bucket.upload(),it asks me for a file path.

You don't need to save it to a file at all. You can simply stringify the object with JSON.stringify() , then upload that string to the bucket with File.createWriteStream() , writing the string value directly to the provided stream.
