require-main-filename

What is require-main-filename?

The require-main-filename package is a simple utility that helps you determine the main entry point filename of the currently running Node.js application. This can be particularly useful when you are writing a module that needs to know the entry point of the application it is being used in.

What are require-main-filename's main functionalities?

Get main entry point filename

This feature allows you to retrieve the filename of the main module that started the current application. The code sample demonstrates how to use the package to log the main filename to the console.

const requireMainFilename = require('require-main-filename');
console.log(requireMainFilename());

Other packages similar to require-main-filename

find-root

The find-root package is used to find the root directory of a Node.js project by traversing up the current directory until it finds a directory containing a package.json file. It is similar to require-main-filename in that it helps identify a key directory in a Node.js project, but it focuses on the project root rather than the main entry point file.

pkg-dir

pkg-dir is another package that can be used to find the root directory of a Node.js project. It works similarly to find-root but uses a different implementation. It provides a promise-based API and can be used in modern async/await code styles. While it serves a similar purpose in identifying important project directories, it does not provide the filename of the main entry point like require-main-filename does.

app-root-path

app-root-path is designed to allow you to require modules from the root of your application without relying on relative paths. It is somewhat related to require-main-filename in that it deals with project structure and module resolution, but it does not specifically provide the main entry point filename. Instead, it focuses on simplifying the module requiring process from the application's root directory.

README

require-main-filename

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.

Usage

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