express-logging

express-logging

Express middleware to log, using a configurable logger, each request and response.

Installation

npm install express-logging

Basic usage

var express = require('express'),
    expressLogging = require('express-logging'),
    logger = require('logops');

var app = express();
app.use(expressLogging(logger));

app.listen(3000);

Logs

The request is logged with:

logger.info('Request from %s: %s %s', clientIpAddress, requestMethod, requestUrl);

A response without Location header is logged with:

logger.info('Response with status %d in %d ms.', responseStatusCode, duration);

A response with Location header is logged with:

logger.info('Response with status %d in %d ms. Location: %s', responseStatusCode, duration, locationHeader);

Both response log entries include the duration of the whole transaction (between receiving the request until replying with the response).
