- In the root of your node app:
npm i nbrest-logger
Usage:
const logger = require("nbrest-logger");
logger.trace("my message");
logger.debug("my message");
logger.info("my message");
logger.warn("my message");
logger.error("my message");
- Change the log level during runtime:
logger.setLogLevel("ERROR");
logger.setLogLevel("WARN");
logger.setLogLevel("DEBUG");
logger.setLogLevel("trace");
- The default log level is
INFO
, soDEBUG

npm start log=debug // enables debug logs
npm start log=warn // set log level to warn
npm start log=error // set log level to error
