An incredibly simple module for directing logs from eel to a writeable stream, just 6 lines:
module.exports = function (formatter, stream) {
return function (entry) {
var output = formatter(entry)
if (!output) return
stream.write(output + '\n')
}
}Install it like this:
npm install eel-stream
Use it like this:
var fs = require('fs')
var log = require('eel')
var stream = fs.createWriteStream(__dirname+'/myapp.log')
var handler = require('eel-stream')(JSON.stringify, stream)
log.on('entry', handler)
log('test1', {ok: true})
log.error('test2', {ok: false})And get log entries like this in myapp.log:
{"type":"test1","level":"info","timestamp":"2012-06-28T18:48:01.249Z","ok":true}
{"type":"test2","level":"error","timestamp":"2012-06-28T18:48:01.250Z","ok":false}
- formatter: A callback with the signature (entry) -> String|Buffer
- stream: A writable stream
