pino-tiny

pino-tiny

a tiny little log formatter for pino.

yeah, i know, pino-colada...

...but is does some weird black box stuff, and i did not like some of the formatting, and i was generally not too happy about certain things, so...

i made pino-tiny!

using it

pino-tiny is ran like any other pino output mangler, you run it as a process and pipe to it. first you need to install it. it's really not meant to be a production log formatter, so prolly install it in your project as a dev-dependency.

npm i -D pino-tiny
--or--
yarn add --dev pino-tiny

...run it with your application that is already using pino to log stuff...

$ node index.js | pino-tiny

...or put it in your package.json file...

{
  ...
  "scripts": {
    "dev": "nodemon index.js | pino-tiny",
    ...
  }
}

use it in code!

pino-tiny can be used in code too as a prettifier, if you want. here is how you set it up:

const { PinoTinyPrettifier } = require('pino-pretty')
const Pino = require('pino')

const logger = new Pino({
  prettifier: PinoTinyPrettifier(),
  prettyPrint: true
})

logger.trace('trace message')
logger.debug('debug message')
logger.info('info message')
logger.warn('warn message')
logger.error('error message')
logger.fatal('fatal message')

what does pino-tiny do?

• shows log level, 3 characters (and not a emoji icon), color coded, and ??? for custom log levels.
• timestamps (no dates). you know what day it is but millisecond timestamps give you some performance output
• strips all but the msg for output
• if there is are res and req properties in the log data, it will put dimmed request and response info (method, url, status code).
• non-json string data that get piped in (like nodemon) get treated as info logs and outputted.
• does not swallow error messages
• non-pino JSON will be logged as dimmed stringified JSON
