Default Logger instance & custom logger instances

Crow can be used directly as a logger instance, or create additional loggers. This is useful if we intend to log to multiple applications or Woodpecker instance.

var logger = crow.createLogger();
logger.setUrl("<url of woodpecker>");
logger.setApplication("<application name>");
logger.warn("A message to be logged to woodpecker")

Methods

createLogger(options)

creates a new crow logger instance. You can pass in configurations as parameter.

Usage

var logger = crow.createLogger() var loggerWithConfig = crow.createLogger({url: "http://localhost:4000", application: "FooBar", devMode: true})

configure(options)

configures the logger. options include woodpecker instances' url, and application name.

setUrl(url)

Sets the url for crow. This should match the url for your woodpecker instance.

Parameters

url - The url of the woodpecker instance that is being run.

Usage

crow.setUrl('http://localhost:4000')

setApplication(application)

Sets the application for crow. This will determine what logfile the requests go to.

Parameters

application - The name of the current application.

Usage

crow.setApplication('Foobar')

setDevMode(devMode)

Sets crow into dev mode. When in dev mode crow will not attempt to log to woodpecker, and will instead only log to console. This can be used in development, but should not be used in production.

Parameters

devMode - Boolean - true will set crow to devMode. false will set crow back to normal so that it logs to woodpecker. By default crow is not in devMode.

Usage

crow.setDevMode(true)
