silentConsole

Globally overwrite console methods - silence all, filter individually.

Motivation

Just debugging a legacy project and I had too many logs / warnings printing to the console. I started to remove / comment them, but realized they could be useful later on. This module is just an extension of the code I wrote for that use.

Usage

Install

npm install --save-dev silentconsole

How to Implement

You can use it at the file level, but it is best for importing at top level (usually your main entry ie index.js) and using for global silencing / filtering of console output.

Globally silence console.log and console.warn

import silentConsole from 'silentconsole';
silentConsole('log');
silentConsole('warn');
 
console.log('foo'); // will not print to console
console.warn('foo'); // will not print to console
console.info('foo'); // will print 'foo' to console

Globally filter console.log and console.warn with filter method as second argument to silentConsole

import silentConsole from 'silentconsole';
silentConsole('log', (text) => !text.includes('bar'));
silentConsole('warn', (text) => !text.includes('baz'));
 
console.log('foo'); // will print 'foo' to console
console.log('bar'); // will not print to console
 
console.warn('foo bar'); // will print 'foo bar' to console
console.warn('foo bar baz'); // will not print to console
 

Globally silence console.log, but allow it for single instances

original will be added to the console object storing all of the original methods of console.

import silentConsole from 'silentconsole';
silentConsole('log');
 
console.log('foo'); // will not print to console
console.log('bar'); // will not print to console
 
console.original.log('foo'); // will print 'foo' to console
 

Globally set as false, restore to make further statements work

This is not a great good use.

Either call method again with no 2nd parameter

import silentConsole from 'silentconsole';  
silentConsole('log');
console.log('foo'); // will not print to console
console.log('bar'); // will not print to console
 
silentConsole('log');
console.log('foo'); // will print 'foo' to console
console.log('bar'); // will print 'bar' to console
 
 

Or call method again with 2nd parameter false as in, do not override log.

import silentConsole from 'silentconsole';  
silentConsole('log');
console.log('foo'); // will not print to console
console.log('bar'); // will not print to console
 
silentConsole('log', false);
console.log('foo'); // will print 'foo' to console
console.log('bar'); // will print 'bar' to console
 
 

Prints all arguments passed like a standard console method

Even if you setup the silentConsole, you can still pass in multiple arguments. The printed results will be a bit different depending on what you pass as last argument.

import silentConsole from 'silentconsole';
silentConsole('log', (text) => !text.includes('test'));
 
console.log('foo', 'bar', 'baz'); // will print 'foo bar baz' to console
console.log('foo', 'bar'); // will print 'foo bar' to console
