lws-spa

lws-spa is a middleware plugin for lws (local-web-server) that adds Single Page Application support. As of version 4.1.1 (stable, active maintenance), it allows you to serve a SPA by providing a fallback file (e.g., app.html) that is returned for non-asset requests, with configurable asset detection using regular expressions or filesystem checks. It integrates seamlessly into lws's plugin architecture and is updated occasionally; the package is part of the lws ecosystem and targets Node.js >=12.17. Compared to generic static file servers, lws-spa provides SPA-specific options like asset testing via regex or filesystem, making it a focused solution for SPA development.
