Motivation

We are lazy! Let make it as easy as possible to config.

Installation

npm install --save enhance-console-log

Setup

Just import and call on your entry point

const enhanceConsoleLog = require('enhance-console-log')
enhanceConsoleLog()

Configurationn

// Default configuration
enhanceConsoleLog({
    dateFormat: 'YYYY-MM-DD HH:mm:ss.SSS',
    separator: '\t---',
    levelColor: {
        'debug': '#a0a0a0', 
        'log': '#dbdbdb', 
        'info': '#55a6e8', 
        'warn': '#f7b737',
        'error': '#b21111', 
    },
    // disabled some log level
    disabledLevel: {
        warn: true,
        log: process.env.NODE_ENV === 'production'
    }
})

Simple Usage

Just call following console log function, debug, log, info, warn and error

console.debug('This is console.debug()')
console.log('This is console.log()')
console.info('This is console.info()')
console.warn('This is console.warn()')
console.error('This is console.error()')

You will get following log with color if your terminal support

2019-03-09 00:57:48.741 DEBUG   --- This is console.debug()
2019-03-09 00:57:48.741 LOG     --- This is console.log()
2019-03-09 00:57:48.741 INFO    --- This is console.info()
2019-03-09 00:57:48.741 WARN    --- This is console.warn()
2019-03-09 00:57:48.741 ERROR   --- This is console.error()

Helper Logging Function

We provide some logging helper patch directly to console object

console.debugWithPrefix(prefix: string)
console.logWithPrefix(prefix: string)
console.infoWithPrefix(prefix: string)
console.warnWithPrefix(prefix: string)
console.errorWithPrefix(prefix: string)

Example

const orderInfoLog = console.infoWithPrefix('order:111111')
const orderLog = console.logWithPrefix('order:111111')

orderInfoLog('created')
orderLog('trying to update')
orderInfoLog('updated')

You will get following log

2019-03-09 00:57:48.742 INFO    --- [order:111111] created
2019-03-09 00:57:48.742 LOG     --- [order:111111] trying to update
2019-03-09 00:57:48.742 INFO    --- [order:111111] updated
