snooplogg

SnoopLogg

Laid back logging.

Installation

npm install snooplogg

Features

• Built-in and custom log levels
• Ability to snoop on other snooplogg instances nested in dependencies
• Pipe messages to one or more streams
• Namespacing
• Filter messages using the DEBUG (or SNOOPLOGG) environment variable
• Includes helper libraries for your convenience
  • chalk
  • figures (exported as symbols)
  • humanize
  • moment
  • pluralize
• Similar API to TJ's debug:
  • const debug = snooplogg('myapp').log;

Examples

import log from 'snooplogg';

log.trace('bow'); // writes to stdout/stderr if DEBUG matches + all pipes

log.info('wow')
   .warn('wow')
   .error('wow');

import snooplogg from 'snooplogg';

const log = snooplogg('myapp');
log.info('bow', 'wow', 'wow'); // writes to stdout/stderr if DEBUG=myapp + all pipes

import snooplogg from 'snooplogg';

const log = snooplogg.stdio('yippy yo');
log.info('bow', 'wow', 'wow'); // writes to stdout/stderr + all pipes

const log = snooplogg.enable('*')('yippy yay');
log.info('bow', 'wow', 'wow'); // writes to stdout/stderr + all pipes

import snooplogg from 'snooplogg';

const log = snooplogg
	.pipe(someWritableStream);

log.info('yippy', 'yo');

# macOS and Linux
$ DEBUG=izzle node loggfather.js

# Windows PowerShell
> $Env:DEBUG="izzle" node loggfather.js

# Windows Command Prompt
> set DEBUG=izzle
> node loggfather.js

Note: You may also use the SNOOPLOGG environment variable to avoid conflicts with other libraries that use debug

Listen for messages from all SnoopLogg instances, even from other dependencies.

import snooplogg, { snoop } from 'snooplogg';

snoop();

const log = snooplogg('bumpin');

log('one');
log
  .trace('two')
  .debug('three')
  .info('and to the four');

log.warn(`It's like this`);
log.error('and like that');
log.fatal('and like this');

import snooplogg, { type } from 'snooplogg';

type('jin', { color: 'cyan' });
type('juice', { color: 'yellow' });

const log = snooplogg();

log.jin('parents ain\'t home');
log.juice('too much drama', true);

API
