import path from 'path'; import fs from 'fs'; fs.mkdirSync(path.join(__dirname, 'folderName')); I want to create directories in node, when I require the modules (commonjs) everything works but when I change the type in my package.json to module and use imports the folder doesn't get created, what could I be doing wrong?
There is no __dirname in an ESM module. If it's something you need, you can manufacture it with this:
import path from 'path'; import { fileURLToPath } from 'url'; const __filename = fileURLToPath(import.meta.url); const __dirname = path.dirname(__filename); But, many of the functions in the fs module can take import.meta.url more directly. See this other answer for details on that.
I figured __dirname isn't available on es6 modules so I just replaced that with './'. You could use an npm package for that if you are looking for elegance.
./ will use the current working directory which may or may not be the same as __dirname. In a top level module file in your project, it will be the same thing. In an imported module from the node_modules directory, the current working directory will have no connection at all to what __dirname would have been.
__dirnamein an ESM module. You will have to manufacture it fromimport.meta.url. You can search and find examples for how to do that. For examples, see here.
