Connect Pushstate Middleware

connect-pushstate is a Connect middleware designed to facilitate client-side routing in single-page applications (SPAs) by rewriting non-asset requests to the application's root. Released as version 1.1.0, this package appears to be abandoned, with its last update occurring approximately nine years ago. It operates by identifying requests that lack a file extension (presumed to be application routes) and internally redirects them to the root path, while preserving the original URL for the client-side router to process. Requests with file extensions (e.g., for images, stylesheets, JavaScript files) are left untouched. The middleware offers optional `root`, `allow`, and `disallow` regular expression configurations to provide finer control over which paths are affected, making it suitable for scenarios where an API or specific server-rendered pages coexist with an SPA. Its key differentiator lies in its simple, focused approach within the `connect` ecosystem, providing a lightweight solution for pushstate routing without the overhead of full-fledged server-side frameworks.
