@roarr/middleware-serialize-error

Serializes error objects in the Roarr message context.

Behaviour

The current implementation maps only the direct context properties.

Raise an issue if you have a use case that requires deep property mapping.

Usage

import log from 'roarr';
import createSerializeErrorMiddleware from '@roarr/middleware-serialize-error';

const childLog = log
  .child({name: 'foo'})
  .child(createSerializeErrorMiddleware());

const error = new Error('foo');

log.debug({error}, 'bar');
childLog.debug({error}, 'bar');

// {"context":{"logLevel":20,"error":{}},"message":"bar","sequence":0,"time":1531918373676,"version":"1.0.0"}
// {"context":{"logLevel":20,"error":{"name":"Error","message":"foo","stack":"[REDACTED]"}},"message":"bar","sequence":1,"time":1531918373678,"version":"1.0.0"}
