Description

I was looking to access the child object, I want to make so that it prepends the message object.

Here I log what inputArgs contains inside hooks.logMethod

after having called logger.child({"featureName":"MY FEATURE"}

{ inputArgs: [ 'special' ] }
{"level":30,"time":1597765635449,"featureName":"MY FEATURE","message":"special"}

I am trying to make a function that will prepend that name to message, so it becomes

{"level":30,"time":1597765635449,"featureName":"MY FEATURE","message":"MY FEATURE: special"}

Research direction
Examine hooks.logMethod in pino's source code. Determine how to access the child logger's custom properties (like featureName) inside the hook. Look at how child loggers are created and how they merge properties. Consider passing the child's custom properties to the logMethod hook. Review issue comments for any suggested approaches. The final implementation should prepend the child's featureName to the message string.
