Logger

A single pre-configured Pino logger: pretty-printed and colourised in development, plain JSON at info level in production. It is an opinionated default so applications stop rewriting the same transport wiring, and JSON in production is what log aggregators want to ingest. pino-pretty is an optional dependency and the logger probes for it, falling back to JSON rather than throwing; if you need custom levels, redaction or child loggers, construct your own Pino instance — this export is intentionally not configurable.

Example​

import { logger } from '@rtorcato/js-common/logger'

logger.info({ userId, plan }, 'subscription started')
logger.error({ err }, 'checkout failed')

Pretty-printed and colourised when NODE_ENV is not production; single-line JSON at info level when it is, which is the shape log aggregators want. Need redaction, custom levels or child loggers? Construct your own Pino instance — this export is deliberately not configurable.

Import​

import { logger } from '@rtorcato/js-common/logger'
