esm-file-dir
esm-file-dir is a Node.js package that allows you to easily get __dirname and __filename values in an ES Modules environment, without the need for imports.
Usage
Import package to your root file (e.g., index.js):
// In ".mjs" script or a script under "type": "module" package
import "esm-file-dir";Retrieve the results:
console.log(__dirname(import.meta));
console.log(__filename(import.meta));or use __dirname and __filename like under commonjs module:
let __dirname = __dirname(import.meta);
let __filename = __filename(import.meta);
console.log(__dirname, __filename);Difference from others libraries
There are numerous similar libraries available in the ecosystem, but they typically require importing dirname or filename functions to use. esm-file-dir differentiates itself by directly injecting these functions into the global context, which not only streamlines your code but also enhances usability.
// not doing like this
import { __dirname, __filename } from 'others-libraries';
// instead
import "esm-file-dir";It's so easy to use!
