__dirname is not defined

Question

I don't understand why my Google Cloud Run instance doesn't know what __dirname is

I have an expressjs server that has this in it:

import path from 'path';

const App = express()
    .get('/*', (_req, res) => {
      res.sendFile(path.join(__dirname, '.', 'index.html'));
    })

I get a compile error __dirname is not defined

__dirname is only available in script files save with .js ext — Ankit, Nov 23 '20 at 06:36
this is a js file, it's expressjs. https://cloud.google.com/functions/docs/concepts/exec — PositiveGuy, Nov 23 '20 at 06:58

Rename to __dirname it should be point to path.join(__dirname, './src'), or you can create using const __dirname = path.resolve(path.dirname(''));

`path.resolve(path.dirname(''))` produces the current working directory, not the directory the file resides in. – portalguy15837 May 05 '22 at 16:49
