Assuming you are working from a module, this solution should work, and also gives you __filename support as well

import path from 'path';
import { fileURLToPath } from 'url';

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

The nice thing is that you are also only two lines of code away from supporting require() for CommonJS modules. For that you would add:

import { createRequireFromPath } from 'module';
const require = createRequireFromPath(__filename);
