log4js-http

An appender for log4js-node which support an http logger middleware.

Note

Use request internally

Installation

``
$ npm i --save log4js-http
`

Usage

Config log4js-http is same as the original log4js-node.

$3

`javascript

const log4js = require('log4js')

log4js.configure({
appenders: {
http: {
type: 'log4js-http',
layout: {type: 'basic'},
protocol: 'optionnal protocol, http by default',
host: 'mandatory, host of your http middleware',
port: optionnal port of your http middleware (80 by default),
path: 'optionnal path (/ by default)',
headers: 'optionnal headers'
}
},
categories: {default: {appenders: ['http'], level: 'info'}}
})

const logger = log4js.getLogger()

logger.info('something to log')

`
NB :

url is mandatory, headers are optionals.

headers need to be a key/value object.

ex: headers: {key1:value1,key2:value2}

$3

If you send objects, the log4js output formatting will be bypassed

`javascript

const log4js = require('log4js')

log4js.configure({
appenders: {
http: {
type: 'log4js-http',
protocol: 'optionnal protocol, http by default',
host: 'mandatory, host of your http middleware',
port: optionnal port of your http middleware (80 by default),
path: 'optionnal path (/ by default)',
headers: 'optionnal headers',
object: true,
addLevel: true
}
},
categories: {default: {appenders: ['http'], level: 'info'}}
})

const logger = log4js.getLogger()

logger.info({'message': 'something to log'})

`

object: true/false, if not present, log is considered to be a string.

addLevel: true/false, auto add level attribute to your object. False if not present.

`javascript
{'message': 'something to log'} -> {'message': 'something to log', level: 'INFO'}
