Sink for records where the final processing and serialization happens.
npm install --save record-sinkThis module is building block for creating message logging system and as such doesn't do much on it's own. By combining it with some stream magic it's possible to create a quick and dirty log method that writes neatly formatted log entries to stderr and to a file.
var Sink = require('record-sink')
, Record = require('log-record')
, through2 = require('through2')
, fs = require('fs')
, logger
logger = through2.obj({objectMode: true}, function (data, enc, cb) {
cb(null, data)
})
logger.pipe(new Sink())
logger.pipe(new Sink(fs.createWriteStream('application.log')))
function log() {
var args = Array.prototype.slice.call(arguments)
, msg = args.shift()
, record = new Record('main', 20, new Date(), msg, args)
logger.write(record)
}
log("hello %s", "world")
