`express-spa-router` is a Node.js middleware that simplifies routing for single-page applications by internally redirecting non-AJAX requests to the client-side app router. It's designed for developers building modern SPAs with client-side URL routing (like Backbone) who want to avoid repetitive conditional logic in their Express routes. The middleware ensures external links and manual URL entries load the same client-side app while preserving the requested URL for client-side routing.
