pino-prettier
A terminal pino json-stream beautifier, based on pino-pretty
usage
Given that your svr.js
uses pino
and emits json-stream
to stdout, then:
node svr.js | pino-prettier
installation
global
npm i -g 'pino-prettier'
After which, your machine has learnt a new command, pino-prettier
to which you may pipe the stdoutput of your pino logger program.
local to project
npm i 'pino-prettier'
After which you may use it in your package.json
scripts.
e.g.:
"scripts": {
...
"run": "node svr.js",
"run:pretty": "node svr.js | pino-prettier",
...
},
what's the difference from pino-pretty
?
- meta objects are formatted using
util.inspect
which uses colors instead of the noisyjson.stringify
- timestamp is "humanized" as just
HH:MM:ss.l
- the log channel is part of the formatted main line, and colorized with a unique color per channel.
- level field appears first, to make its color distinctive against the indent black, and less confusing with the colorized channels.
- fields are optimized for developer machine (filter out
host
,pid
,version
, etc)
Customization
This first version is customizable as far as CLI arguments supported by pino-pretty
: it works by hacking the --config
parameter, and injecting it's own config file, and does some hacky stuff on the way.
However, every customization that is supported by CLI arguments are stronger than the baked-in config file shipped with this package.
Have fun :)
