pino-abstract-transport

What is pino-abstract-transport?

The pino-abstract-transport package provides a way to create custom transports for Pino, a fast JSON logger for Node.js. These transports can be used to process or forward log messages to different destinations or services in a structured and efficient manner. The package simplifies the development of these transports by abstracting common tasks and providing a standard interface for implementation.

What are pino-abstract-transport's main functionalities?

Creating a custom transport

This feature allows developers to create a custom transport for Pino logs. The code sample demonstrates how to use the `build` function from `pino-abstract-transport` to create a simple transport that prints log messages to the console.

"use strict";\nconst { build } = require('pino-abstract-transport');\nasync function myTransport(opts) {\n  return async function (source) {\n    for await (const obj of source) {\n      console.log(obj);\n    }\n  };\n}\nmodule.exports = build(myTransport);"

Other packages similar to pino-abstract-transport

pino-pretty

Pino-pretty is a module that can be used to format Pino log messages in a more human-readable way. Unlike pino-abstract-transport, which is focused on creating custom transports, pino-pretty is specifically designed for pretty-printing log messages in development environments.

pino-elasticsearch

Pino-elasticsearch is a transport for Pino that forwards log messages to Elasticsearch. It provides a more specialized functionality compared to pino-abstract-transport, which offers a generic interface for building various types of transports.

Install

npm i pino-abstract-transport

Usage

import build from 'pino-abstract-stream'

exports default async function (opts) {
  return build(async function (source) {
    for await (let obj of source) {
      console.log(obj)
    }
  })
}

or in CommonJS and streams:

'use strict'

const build = require('pino-abstract-stream')

module.exports = function (opts) {
  return build(function (source) {
    source.on('data', function (obj) {
      console.log(obj)
    })
  })
}

API

build(fn, opts) => Stream

Create a split2 instance and returns it. This same instance is also passed to the given function, which is called synchronously.

Events emitted

In addition to all events emitted by a Readable stream, it emits the following events:

• unknown where an unparsaeble line is found, both the line and optional error is emitted.
