This project provides a Node.js loader that enables support for import maps, allowing developers to customize module resolution by mapping module names to specific file paths or URLs. It's designed for Node.js developers who want to use import maps to manage dependencies in a way similar to how they work in web browsers, providing a centralized way to configure module paths and aliases. The loader works by registering a custom module loader that reads import map configurations from a `node.importmap` file or through runtime updates via a message channel.
