create-require

What is create-require?

The create-require npm package is designed to dynamically create a `require` function at a given path. This is particularly useful in scenarios where you need to resolve modules or require files relative to a specific directory, rather than the current working directory of the process. It can be used to simulate the behavior of Node.js's `require` in different contexts or to dynamically load modules from various locations in a filesystem.

What are create-require's main functionalities?

Creating a custom require function for a specific directory

This feature allows you to create a new `require` function that resolves modules as if it was called from the specified directory. This is useful for loading modules from a directory different from the current script's directory.

const createRequire = require('create-require');
const myRequire = createRequire('/path/to/my/directory');
const myModule = myRequire('./myModule');

Other packages similar to create-require

import-fresh

Similar to create-require, import-fresh allows you to require a module afresh, ensuring that it is re-evaluated. It's useful for testing and situations where you need to bypass Node's require cache. However, it doesn't allow specifying a directory for module resolution like create-require does.

proxyquire

Proxyquire is designed for overriding dependencies during testing. It allows you to create a custom `require` function that can return mock modules instead of the real ones. While it serves a different primary purpose (mocking for tests), it shares the concept of creating a custom require function with create-require.
