churchill

A winston express logger called churchill

Installing

npm install churchill

Running the tests

npm test

Usage

var churchill = require('churchill');
app.use(require('churchill')(winston));

Specify a log level

app.use(require('churchill')(winston, 'express'));

Using multiple loggers

var logger = new (winston.Logger).....
app.use(require('churchill').add(logger, 'express').add(logger, 'someOtherLogLevel'));

req.logger The first logger will be automatically added to req.logger This then gives you the facility to use the logger from req like so:

req.logger.log('something in winston');
req.logger.error('Oh noe!');

req.log Churchill will also add a log method to the request object, which will log to all mounted loggers:

req.log('info', 'something in winston');
req.log('error', 'OH NO!');

To disable this set reqLogger to false in the options.

Formatting

var logger = new (winston.Logger).....
app.use(require('churchill').add(logger, 'express').format(function (obj, req, res) {
  obj.somethingInteresting = req.params.moreData;
}));

Suppressing GET params from logs

var churchill = require('churchill')
churchill.options.logGetParams = false

Output

In it's simplest form a console output looks like this:

info:  status=200, method=GET, url=/, response_time=4
info:  status=304, method=GET, url=/, response_time=1
info:  status=304, method=GET, url=/, response_time=0
