winston-error

Error helper for winston.

Add a decorator on winston.error() (by default, customizable) which, when an error is passed as first argument, also adds it in metadata and converts the call to a standard winston (message, metadata, ...). The full error object is not added, only standard fields .name, .message and .stack are copied (by default, customizable).

Install

npm install winston-error

Usage

var winston = require('winston');
var winstonError = require('winston-error');
 
var logger = new winston.Logger();
winstonError(logger);
 
logger.error(new Error('My error')); // will add message, stack and code in meta

Copied fields can be explicitly selected, with a default value :

winstonError(logger, {
  pickedFields: {
    name: undefined,
    message: undefined,
    stack: undefined,
    status: 500
  }
});
 
logger.error(new Error('My error')); // will copy name, message, stack and status in meta

Decorated levels can be explicitly selected :

winstonError(logger, {
  decoratedLevels: [
    'error',
    'warn'
  ]
});
 
logger.error(new Error('My error')); // will copy name, message and stack in meta
logger.warn(new Error('My error')); // will copy name, message and stack in meta
