pino-utils

library1.4.0jsnpmunverified

pino-utils v1.4.0 is a zero-dependency, colorized logger utility for Node.js that provides a higher-level API over pino with emoji icons, ISO timestamps, and six log levels (trace, debug, info, warn, error, fatal). It ships TypeScript definitions and supports both ESM and CJS. Similar to pino-pretty but packaged as a standalone logger rather than a transport, it offers immediate usability without additional configuration. The package is actively maintained with a moderate release cadence and is ideal for projects wanting a prettified console logger without pulling in heavy formatters.

Code

Verified usage

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

logger

✓ import { logger } from 'pino-utils'

✗ const logger = require('pino-utils').logger

Default export is not available; logger is a named export. CommonJS require must access .logger property.

pino-utils (using require)

✓ const { logger } = require('pino-utils')

✗ const pinoUtils = require('pino-utils'); pinoUtils.logger.info('test')

Destructure directly in require to avoid extra variable.

TypeScript types

✓ import type { Logger } from 'pino-utils'

Types are included; use import type for type-only imports to avoid bundling runtime code.

Demonstrates basic usage of the logger with all log levels, showing colorized and timestamped output.

import { logger } from 'pino-utils'; logger.info('Application started'); logger.debug('Debug info', { key: 'value' }); logger.warn('Warning!'); logger.error('Error occurred', new Error('Something went wrong')); logger.fatal('Fatal error'); // Output will be colorized with emoji and timestamp.

Debug

Known issues

gotchapino-utils is not a pino transport; it wraps pino internally. You cannot pipe pino streams directly.

fix

Use pino-pretty as a transport if you need to format pino streams. pino-utils is a standalone logger.

affects: >=1.0.0

gotchaThe logger object is a singleton. Importing in multiple modules returns the same instance.

fix

If you need separate loggers with different configurations, consider using pino directly or creating multiple instances via pino-utils API (if available in future versions).

affects: >=1.0.0

deprecatedThe default export is not available. Using `import pinoUtils from 'pino-utils'` returns undefined.

fix

Use named import: import { logger } from 'pino-utils'

affects: >=1.0.0

Errors

Common errors & fixes

SyntaxError: Cannot use import statement outside a module

Trying to use ESM import in a CommonJS Node.js project without proper configuration.

fix

Add "type": "module" to package.json or use require with destructuring: const { logger } = require('pino-utils')

TypeError: logger.info is not a function

Using default import instead of named import: import logger from 'pino-utils' (undefined).

fix

Use named import: import { logger } from 'pino-utils'
