loggerHandler function

Future<Response?> Function(Request request, FutureOr<Response?> nextHandler()) loggerHandler()

A middleware that logs incoming HTTP requests in the console with details such as:

• HTTP method
• Request path
• Response status code
• Time taken to process the request

The log is styled using ANSI escape codes for color, italics, and underline, and is printed using the logCustom function.

Example log output:

[REQUEST] → GET /api/chefs [200] (12ms)

• HTTP methods are shown in uppercase.
• Duration is measured in milliseconds.
• The output is color-coded using light cyan (ANSI 96).

Returns a middleware function that can be used with app.wrap() in Sirius.

Example usage:

app.wrap(loggerHandler());

Returns: A middleware function of type Future<Response> Function(Request, Future<Response> Function())

Implementation

Future<Response?> Function(
        Request request, FutureOr<Response?> Function() nextHandler)
    loggerHandler() {
  return (request, nextHandler) async {
    final startTime = DateTime.now();
    final response = await nextHandler();
    final duration = DateTime.now().difference(startTime);

    logCustom(
      'REQUEST',
      '→ ${request.method} ${request.path} '
          '[${response?.statusCode}] (${duration.inMilliseconds}ms)',
      colorCode: 96,
      italic: true,
      underline: true,
    );

    return response;
  };
