BloomMiddleware class abstract

Composable middleware interface for Bloom API routes, full-stack SSR servers, and gateways.

Middleware can inspect or modify incoming BloomRequest instances, short-circuit execution early (e.g., for authentication failures or CORS preflight), and inspect or modify outgoing BloomResponse instances after invoking next.

Example

class TimingMiddleware implements BloomMiddleware {
  @override
  Future<BloomResponse?> handle(BloomRequest request, BloomNextFunction next) async {
    final stopwatch = Stopwatch()..start();
    final response = await next();
    stopwatch.stop();
    response.headers['X-Response-Time'] = '${stopwatch.elapsedMilliseconds}ms';
    return response;
  }
}

router.use(TimingMiddleware());
