Express Basic Auth Middleware

express-basic-auth is a lightweight, plug-and-play middleware designed for adding HTTP Basic Authentication to Express applications. Its current stable version is 1.2.1, with the latest release in October 2021. The package has seen sporadic updates, with v1.0.0 (production ready) in 2017 and v1.1.0 (TypeScript support) in 2020. It offers flexibility through static user configurations or custom synchronous/asynchronous authorizer functions. A key differentiator is the inclusion of a `safeCompare` utility, which aids in mitigating timing attacks for secure credential comparison. The middleware also allows customization of unauthorized responses, including JSON, and exposes parsed credentials on `req.auth`.
