Flowstate Per-Request State Management

Flowstate is a Node.js middleware designed for managing and propagating per-request state across a sequence of HTTP requests within an Express or Connect application. It allows developers to implement 'flows' where state is maintained across multiple redirects and user interactions, culminating in a desired outcome. By default, it integrates with existing session middleware, isolating state for specific request sequences rather than global session state. State propagation relies on `return_to` and `state` query/body parameters, which the middleware automatically handles on redirects and exposes via `res.locals` for manual inclusion in views. The current and only stable version is 0.6.0, published in 2017. The package appears to be abandoned, with no releases or significant activity since that time, making it potentially incompatible with modern Node.js and Express versions.
