Express Request Timeout Middleware

This package, `timeout-middleware` (current version 0.6.1), provides an Express.js middleware designed to gracefully handle slow requests by enforcing a response timeout. It intercepts `res.status`, `res.sendStatus`, and `res.send` methods, checking a `res.timedout` flag before allowing further modifications to the response. Upon timeout, if headers have not yet been sent, it automatically sets the response status to 503 (Service Unavailable) and sends a 'Request Timeout' message. This approach differs from alternatives like `connect-timeout` which require manual `haltOnTimedout` checks after every middleware in the chain. The library aims for a more 'DRY' (Don't Repeat Yourself) implementation by wrapping the core response methods, preventing accidental operations on a timed-out request. As a pre-1.0 version, future API changes are possible, and its release cadence is not explicitly defined in the provided information.
