axum-extra - v0.6.0

  // before
  Router::new().merge(SpaRouter::new("/assets", "dist"));
  // with ServeDir
  Router::new().nest_service("/assets", ServeDir::new("dist"));
  // before with index_file
  Router::new().merge(SpaRouter::new("/assets", "dist").index_file("index.html"));
  // with ServeDir + ServeFile
  Router::new().nest_service(
  "/assets",
  ServeDir::new("dist").not_found_service(ServeFile::new("dist/index.html")),
  );
