Express Report-To Middleware

This package provides Express.js middleware for setting the HTTP `Report-To` response header, crucial for client-side error reporting via browser APIs. Currently at version 1.1.0, it appears to be in a maintenance phase with no major updates since 2021. Its primary function is to configure reporting endpoints for various browser features, such as `Content-Security-Policy` (CSP) violation reports, Network Error Logging (NEL), or Intervention Reports. A key differentiator is its focus solely on configuring the `Report-To` header, rather than implementing the reporting mechanisms themselves. This design choice means it requires integration with other modules (e.g., `network-error-logging` for NEL) to make the reporting functional. The module offers a structured way to define report groups, `max_age`, `include_subdomains`, and multiple prioritized endpoints, adhering to the W3C Reporting API specification.
