The logging package provides convenience APIs for logging information while your app is running. The
Logger protocol declares a common interface for logging information. A default
PrintLogger is available, but you can implement custom loggers to suit your specific needs.
First, you will want to use a
Container to create an instance of
Logger. Then you can use the convenience methods to log information.
let logger = try req.make(Logger.self) logger.info("Logger created!")
Logger in the API docs for a list of all available methods.
Check out Service → Services for more information on how to register a custom logger.
