Question

How to get filename of script being executed in NodeJS application?

Answer 1

You can use variable __filename

http://nodejs.org/docs/latest/api/globals.html#globals_filename

Answer 2

Use the basename method of the path module:

var path = require('path'); var filename = path.basename(__filename); console.log(filename); 

Here is the documentation the above example is taken from.

As Dan pointed out, Node is working on ECMAScript modules with the "--experimental-modules" flag. Node 12 still supports __dirname and __filename as above.

If you are using the --experimental-modules flag, there is an alternative approach.

The alternative is to get the path to the current ES module:

const __filename = new URL(import.meta.url).pathname; 

And for the directory containing the current module:

import path from 'path';  const __dirname = path.dirname(new URL(import.meta.url).pathname);
