process.mainModule is deprecated in nodejs

Question

module.exports = path.dirname(process.mainModule.filename)

process.mainModule.filename is deprecated in nodejs. Is there any alternative method to get a current directory of the file?

The entry point of the current application can be obtained by checking require.main.filename.
__dirname gets you the directory the module is in.
process.cwd() gets the current working directory.

Chances are you want one of these.
