HTTP Basic Auth for Node.js

The `basic` package provides a minimalist HTTP Basic Authentication middleware for Node.js applications. It abstracts the process of parsing the `Authorization` header and validating user credentials against a provided callback function. As of its latest stable version, 2.0.3 (published over seven years ago), the package is primarily designed for CommonJS environments and integrates directly with Node.js's native `http` module. It follows a callback-based asynchronous pattern for credential verification. Its primary differentiation lies in its extreme simplicity and lack of external dependencies, making it a lightweight option for adding basic authentication to a server. Due to its age, it receives infrequent updates and may not natively support modern JavaScript features like Promises or ES Modules without additional wrappers.
