Debug HTTP printer for pino

[1574071926285] GET http://localhost:20000/api/activity/component 200\n

Usage as Pino Transport

You can use this module as a pino transport like so:

const pino = require('pino')
const transport = pino.transport({
  target: 'pino-http-print',
  level: 'info',
  options: {
    destination: 1, // optional (default stdout)
    all: true,
    colorize: false,
    translateTime: true
    ... // other options
  }
})
pino(transport)

The options object's properties are described below. There is only one extra property:

prettyOptions: this property is forwarded to pino-pretty for non-http logs (when all is true). It must be pino-pretty options object.

Usage as module

Supports

const { httpPrintFactory } = require('pino-http-print')
const printer = httpPrintFactory()
var logger = require('pino-http')(printer)

const { httpPrintFactory } = require('pino-http-print')
const printer = httpPrintFactory()
const logger = require('express-pino-logger')(printer)

Same for koa-pino-logger and restify-pino-logger, just pass in the printer stream.

API

httpPrintFactory(options, pinoPrettyOptions) => ( Function(Stream) => Stream )

Returns a new printer. The common options between this and pino-pretty options are set from the first object itself. pinoPrettyOptions is forwarded to pino-pretty for non-http logs (when all is true).

See the Options section for all possible options.

printer(Stream) => Stream

Returns a stream that will pull off

Options

Options argument for httpPrintFactory with keys corresponding to the options described in CLI Arguments:

{
  colorize: colorette.isColorSupported, // --colorize
  all: false, // --all
  translateTime: false, // --translateTime
  relativeUrl: false, // --relativeUrl
  lax: false  // --lax
}

The colorize default follows colorette.isColorSupported.

Usage as Pino Legacy Transport

Pino supports a legacy transport interface that is still supported by this module.

npm install -g pino-http-print

Spin up server that uses a pino http logger and pipe it to pino-http-print

node server | pino-http-print

CLI Arguments

-all (-a): Causes pino-http-print to also print non-HTTP log messages by passing them through to pino-pretty.
--colorize (-c): Adds terminal color escape sequences to the output.
--translateTime (-t): Translate the epoch time value into a human readable date and time string. This flag also can set the format string to apply when translating the date to human readable format. This is the same as pino-pretty translateTime

--relativeUrl (-r): print only the relative url
