This plugin adds a logger to your Gasket application and introduces lifecycles for custom logger implementations. This plugin is included by default in all Gasket applications.
At this time, there is only one plugin which implements a
custom logger: @gasket/plugin-winston.
To implement a custom logger, hook the createLogger lifecycle.
Your hook must be synchronous and return an object with this shape:
type Logger = {
[level: string]: (...args: Array<any>) => void,
child: (metadata: Object) => Logger,
close?: () => Promise<void> // Optional
}The level keys are the log levels that your logger supports. The values are
functions that accept any number of arguments and write them to the log. Your
logger must support, at minimum, the following levels:
debugerrorinfowarn
The child function is used to create a new logger with additional metadata.
The metadata argument is set of properties that will be included in every log
entry. The child function must return a new logger with the same shape as the
parent logger.
The close function, if supplied, is called when the application is shutting
down and should be used to close any open resources.
If you are contributing to this plugin, use the following to run the tests:
