> interface Logger { > debug(message?: any): void; > info(message?: any): void; > warn(message?: any): void; > error(message?: any): void; > } > ``` This generic interface for loggers supports logging a string at one of four different levels (`debug`, `info`, `warn`, `error`). It's designed to be compatible with Node's `console` as well as commonly used logging packages and is tested against a few of them. Below are the logging libraries we test for compatibility against. ## bunyanconst logger = bunyan.createLogger();
## log4jsconst logger = log4js.getLogger();
## loglevelconst logger = loglevel.getLogger();
## winstonconst logger = winston.createLogger(); ```
