epd/winston-request-logger

Winston based http request logger for express.

winston-request-logger

Winston http request logger for express which is loosely based on express-request-logger.

Getting Started

In an existing express project you can add the following configuration fragment to enable request logging to console, with colors while in development or test.

    app.configure('development', 'test', function(){
        // Request Logging
        var logger = new (winston.Logger)({ transports: [ new (winston.transports.Console)({colorize:true}) ] });
        app.use(require('winston-request-logger').create(logger));
    });

Custom formats

You can optionally specify a second argument to create(logger, [format]) to customize the object sent to Winston:

	app.use(require('winston-request-logger').create(logger, {
		'responseTime': ':responseTime ms',		// outputs '5 ms'
		'url': ':url[pathname]'					// outputs '/some/path'
	}));

Format tokens:

• :date - Timestamp of the request.
• :statusCode - HTTP status code of the request.
• :method - HTTP method (GET, POST, etc.)
• :url[segment] - Segment of the URL requested (Refer to the url module for options).
• :responseTime - Time it took for the response (in milliseconds).
• :ip - The client's IP address (looks to X-forwarded-for header first).

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
