snlog v0.1.1

snlog

A Simple Logger for Node.js

Installation

npm i snlog --save

Features

• shows name of printing module
• shows line number
• may use coloring
• can be controlled by an error level

Example:

const log = require( 'snlog' );

// default errorlevel of clog is 3!
const dbgLog = log.clog( log.colors.FgYellow );

// errLog has error level 0; it will print output 
// if currentErrorLevel is >= 1
const errLog = log.clog( log.colors.FgRed, log.colors.BgWhite, 0 );

errLog( "Current Error Level", log.getErrorLevel() );

let o = {
	name: "snlog",
	arr: [ 1, 2, 3, 4 ],
	f: function test() {}
};

dbgLog( o ); // prints the object
log.setErrorLevel( 1 ); // downgrade current error level
dbgLog( o ); // no output, because of low error level
errLog( "End-of-Example" ); // will print red on white

Result - if the example is named "logger.js":

[logger#10] Current Error Level 5
[logger#18] [name]=snlog; [arr]=1,2,3,4; [f]=function;
[logger#21] End-of-Example
