Strict-Transport-Security Middleware

The `strict-transport-security` package provides Node.js middleware designed to add the Strict-Transport-Security (HSTS) header to HTTP responses. This header enforces secure (HTTPS) connections, preventing downgrade attacks and cookie hijacking in compliant browsers, as specified by RFC6797. It is built to integrate seamlessly with Express.js and Connect-compatible frameworks, allowing developers to define global or path-specific HSTS policies. The package is currently at version 0.3.0, with its latest notable update introducing support for the `preload` option. Its development cadence suggests a mature and stable, yet likely low-maintenance, library focused on a singular security concern. Its primary differentiator is its dedicated functionality for HSTS, offering a lightweight alternative to larger security middleware suites.
