keyFilename from JSON string instead of file

[nodesocket]

Is it possible to pass a JSON string value for keyFilename instead of a local file path? Example usage is if keyFilename is stored in a database as a string and don't want to write to disk.

The contents of the key file are what you have to work with? You can provide a credentials object with the contents of a JSON key file:

new Storage({
  credentials: require('service-account-key-file.json') // (or just a raw JS object)
})

:( What path did you take for docs? We definitely want to make sure we communicate this stuff properly.

Mostly only points to setting the environment variable to the path of the JSON file. I wanted to pass the JSON data via the environment variable instead. So I looked around how to just pass the data instead of letting the SDK search for the environment variable itself.

I googled for a bit and found the client.authClient.fromJSON(). Though after instantiating Storage() and then setting it fromJSON(), it still didn't work. I don't think I found anywhere but here mentioning I can pass it via credentials. Also, my bad because even though I checked the source it slipped my mind to check the parent of StorageOptions :(

Was there another pathway I missed? Please let me know! Thanks for the response!

Just for reference, I was having some trouble with actually getting the credentials in, so here are some things to note:

1. Make sure that the credentials line has the PARSED version of the JSON: credentials: JSON.parse(process.env.GOOGLE_KEY)
2. In the .env file, make sure that the JSON is on 1 line but does NOT have a starting and ending quotation mark: GOOGLE_KEY={"start": "json", "key":"here"....} (example what NOT to do: GOOGLE_KEY="{"start":"json", "key":"here"...}"

Thanks @dannydenenberg #2847 (comment), the credentials piece was the trick for me. Most examples were showing only the keyFile, but switching to credentials worked perfectly when using the googleapis package.

Example .env

YOUR_GOOGLE_JSON_KEY={"type":"service_account","project_id":"XXXXX",....}

Example using Google Analytics API:

import { google } from "googleapis";

const analytics = google.analytics({
  version: "v3",
  auth: new google.auth.GoogleAuth({
    // Your Google service account JSON key as a string. 
    credentials: JSON.parse(process.env.YOUR_GOOGLE_JSON_KEY), // make sure to replace with whatever you call your `.env` variable,
    scopes: ["https://www.googleapis.com/auth/analytics.readonly"]
  })
});

Thanks, the docs say nothing about this. Crazy.
