require.main.filename is great for figuring out the entry point for the current application. This can be combined with a module like pkg-conf to, as if by magic, load top-level configuration.

Unfortunately, require.main.filename sometimes fails when an application is executed with an alternative process manager, e.g., iisnode.

require-main-filename is a shim that addresses this problem.


var main = require('require-main-filename')()
// use main as an alternative to require.main.filename.



You can’t perform that action at this time.
