saylo

Saylo (turn on/off console.log)

Installation

To install this npm package do

npm i -P saylo

Usage

Then from your javascript files import either logger or log directly with:

//var logger = require('saylo');
import logger from 'saylo';
import { log } from 'saylo';

Then you can replace your console.log with either log() or logger.log():

import logger from 'saylo';

const a = 'Hey there how are you?';
const b = function() { 'any type goes' };
logger.log('my log output is: ', a, b); // 'my log output is: ', 'Hey there how are you?' , function () {'any type goes'}

logger.turnOff();
logger.log('my log output is: ', a, b); // no output

logger.turnOn();
logger.log('my log output is: ', a, b); // 'my log output is: ', 'Hey there how are you?' , function () {'any type goes'}

Control through env vars

Before you load the logger module, you can set the environement variable SAYLO_LOGGING like:

process.env.SAYLO_LOGGING=1
// or
process.env.SAYLO_LOGGING=0

and it will turn the logger on or off. You can also store these in a .env file. In which case the import 'dotenv/config'; statement will load them for you. (You need to npm i -P dotenv for this to work.

Roadmap

Next step:

• Create logging sets and subsets, which you can turn on or off for finer control

  logger('level1').log('my string to log');
  logger('level2').log('my string to log');
  // or
  logger1.log('my string to log');
  logger2.log('my string to log');
