pino-prettier is a colorful, zero-dependency logging utility for Node.js and the browser, built on top of pino. Version 1.1.1 is the latest stable release; the package is actively maintained. It provides a pretty-printed, emoji-enhanced log output with six log levels (trace, debug, info, warn, error, fatal) and ISO timestamps. Unlike alternatives like pino-pretty, pino-prettier has no external dependencies and ships with TypeScript definitions. It is designed for developers who want a simple, visually distinct logger that works out of the box.

Install & Compatibility

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

logger

✓ import { logger } from 'pino-prettier'

✗ import logger from 'pino-prettier'

The package exports a named export 'logger', not a default export.

pino

✓ import pino from 'pino'

✗ const pino = require('pino'); import { pino } from 'pino';

pino uses ESM exports; default import is correct for common usage.

LoggerOptions

✓ import type { LoggerOptions } from 'pino'

✗ import { LoggerOptions } from 'pino'

If using as a type, use 'import type' to avoid runtime import errors in TypeScript.

Demonstrates two ways to use pino-prettier: as a pino transport and as a standalone logger.

import { logger } from 'pino-prettier'; import pino from 'pino'; // Create a pino instance with pretty-printing const log = pino({ transport: { target: 'pino-prettier', options: { colorize: true } } }); // Or use the direct logger logger.info('Hello, world!'); logger.warn('This is a warning'); logger.error('An error occurred', new Error('test'));

Debug

Known issues

gotchapino-prettier requires pino as a peer dependency. Not installing pino will cause runtime errors.

fix

Run 'npm install pino' alongside pino-prettier.

affects: >=1.0

gotchaThe exported logger is a named export, not a default export. Using default import will result in undefined.

fix

Use 'import { logger } from 'pino-prettier'' instead of 'import logger from ...'

affects: >=1.0

deprecatedIn pino v7+, using 'transport' target for pino-prettier requires proper configuration. Older patterns may not work.

fix

Ensure pino version is compatible; if using transport, specify target as 'pino-prettier'.

affects: >=1.0

gotchapino-prettier may have limited performance compared to native JSON output due to colorization.

fix

In production, consider disabling colorization or using a faster transport.

affects: >=1.0
