Maps the major Pino / Bunyan logging methods to custom methods
0BSD License
Types and mapper for Pino / Bunyan logging methods.
Support Pino / Bunyan compatible loggers with fallback console.log()
.
BunyanLite
– simplified Pino / Bunyan type subsetsApart from the actual adapter, this module also ships with some useful generic TypeScript types, where BunyanLite
is the most usable of them.
The BunyanLite
type can be used wherever one wants to reference a basic Pino / Bunyan subset. That type can then be fulfilled by Pino, Bunyan, a logger created by this module or by another module implementing the same subset.
BunyanLite
– specifies the lite subset of the Bunyan interface that this module supportsBunyanLogMethod
– specifies the very simple syntax for the individual log methodsBunyanChildMethod
– specified the syntax of the child()
methodBunyanLite
.fatal()
.error()
.warn()
.info()
.debug()
.trace()
.child(data)
createLogger()
– map any logger to BunyanLite
subsetSimple CommonJS example:
const logger = require('bunyan-adaptor')({
log: console.log.bind(console),
error: console.error.bind(console),
});
logger.error('Warning'); // Uses console.error()
logger.info('Informational'); // Uses console.log()
Simple ESM example:
import createLogger from 'bunyan-adaptor';
const logger = createLogger({
log: console.log.bind(console),
error: console.error.bind(console),
});
logger.error('Warning'); // Uses console.error()
logger.info('Informational'); // Uses console.log()
Also available as a non-default export:
const { createLogger } = require('bunyan-adaptor');
import { createLogger } from 'bunyan-adaptor';
Maps options
methods to all seven Bunyan log levels.
.fatal()
– maps to options.fatal
and fallbacks to options.error
and options.log
in that order.error()
– maps to options.error
and fallbacks to options.log
in that order.warn()
– maps to options.warn
and fallbacks to options.log
.info()
– maps to options.info
and fallbacks to options.log
.debug()
– maps to options.debug
and fallbacks to options.verbose
and options.log
in that order.trace()
– maps to options.trace
and fallbacks to options.verbose
and options.log
in that orderoptions.log
itself fallbacks to console.log()
In addition to the above there's also support for:
.child(data)
– used to create a child logger. Defaults to built in method, can be overriden using options.child
