withMiddleware

withMiddleware(middleware, child): Route

Wrap every handler in child’s subtree with the given Middleware. The middleware runs before the handler; it can short-circuit (return without calling next()) or transform the response.

Nesting composes outside-in: withMiddleware(a, withMiddleware(b, get(h))) runs a first, then if it calls next(), b runs, and if b calls next(), the handler h runs.

const protectedRoutes = withMiddleware(
  BearerTokenAuth({ tokens: [process.env.MGMT_TOKEN!] }),
  withMiddleware(
    IpAllowlist({ allow: ['10.0.0.0/8'] }),
    path('cluster', concat(
      path('down', post(handleDown)),
      path('leave', post(handleLeave)),
    )),
  ),
);
