Steps to reproduce

1. Copy quickstart sample into local dir as quickstart.js:

const {authenticate} = require('@google-cloud/local-auth');

async function quickstart() {
  const localAuth = await authenticate({
    scopes: ['https://www.googleapis.com/auth/blogger'],
    keyfilePath: '/path/to/keys.json',
  });
  console.log('Tokens:', localAuth.credentials);
}
quickstart();

2a. Run it (locally):

$ node quickstart.js
node:internal/modules/cjs/loader:933
  const err = new Error(message);
              ^

Error: Cannot find module '/path/to/keys.json'

    '/Users/wescpy/maestro/backup/google-apis/youtube/quickstart.js'
  ]
}

2b. Run it in the cloud (Cloud Shell)... pretty much the same error:

Obviously that filepath isn't real, but changing it to client_secret.json, which is a real file, still fails w/the same error.

3. Just for the heck of it, I added use of the path module, to provide a full path:

const path = require('path');
const {authenticate} = require('@google-cloud/local-auth');

async function quickstart() {
  const localAuth = await authenticate({
    scopes: ['https://www.googleapis.com/auth/blogger'],
    keyfilePath: path.join(__dirname, 'client_secret.json')
  });
  console.log('Tokens:', localAuth.credentials);
}
quickstart();

It still fails, but with a different error now:

$ node quickstart.js
node:internal/errors:464
    ErrorCaptureStackTrace(err);
    ^

TypeError [ERR_INVALID_URL]: Invalid URL
    at new NodeError (node:internal/errors:371:5)

    at Function.Module._load (node:internal/modules/cjs/loader:822:12) {

  code: 'ERR_INVALID_URL'
}

Any help explaining/solving both of these issues will help... thanks!

path/to/key.json in that sample needs to be replaced with the path to a credential json file (like an exported service account key, or user credentials).

An oauth client_secret.json is probably not a credential file (it's likely an OAuth app client secret file).

You might also want to look at https://github.com/googleapis/google-auth-library-nodejs intead of this repository

Thanks Jeff. So what you're saying is that this library is only for service account public/private keypair credentials JSON files, not OAuth client ID/secret JSON files? I thought that was well and swapped in the former, but this library still crashes because it's looking for redirect_uris which aren't in SA keypair creds files. Is it possible it has to be a web server OAuth client ID? (I was trying it for an installed app rather than for web apps.) Why does this library exist alongside the one you linked to? What's the difference b/w them, e.g., their differing use cases? And should this one be archived?

@wescpy I had to change out the credentials path from

const CREDENTIALS_PATH = path.join(process.cwd(), 'credentials.json');

to

const CREDENTIALS_PATH = path.resolve(__dirname, "credentials.json");

You also might need to do the same thing with TOKEN_PATH. very annoying it doesn't work like the example
