express-logging
Advanced tools
Express middleware to log, using a configurable logger, each request and response.
npm install express-logging
var express = require('express'),
expressLogging = require('express-logging'),
logger = require('logops');
var app = express();
app.use(expressLogging(logger));
app.listen(3000);
An optional argument options
can customize enhanced aspects for the logging. This argument is an object with the following elements:
blacklist
is available to prevent some resources from being logged (for example, static resources). This argument is an array of strings. If the URL path starts with any of the elements of the blacklist array, then the logging of this request/response is ignored.policy
is a string to customize how the info is logged. It supports two values: message
or params
. The former serializes all the log entry into a single string message. The latter passes to the logger an object with the log entry parameters and a second argument with the message; this policy is useful in order to process these parameters by systems like logstash. The default value is message
.The following example would ignore any resource available at either /images
or /html
. It also activates the logging policy params
.
var blacklist = ['/images', '/html'];
app.use(expressLogging(logger, {blacklist: blacklist, policy: 'params'}));
### Logging with default policy message
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).
### Logging with policy params
The request is logged with:
var params = {requestClientIp: requestClientIp, requestMethod: requestMethod, requestUrl: requestUrl};
logger.info(params, 'Request from %s: %s', requestMethod, requestUrl);
A response without Location
header is logged with:
var params = {responseStatusCode: responseStatusCode, responseDuration: duration};
logger.info(params, 'Response with status %d', responseStatusCode);
A response with Location
header is logged with:
var params = {responseStatusCode: responseStatusCode, responseDuration: duration, responseLocation: locationHeader};
logger.info(params, 'Response with status %d', responseStatusCode);
Both response log entries include the duration
of the whole transaction (between receiving the request until replying with the response).
