nbrest-logger:

Basic logging framework to format logs to the console in a node app.

Install or Update:

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, so DEBUG and TRACE entries are hidden by default. To change the log level at application startup, pass the log or LOG argument to your node app:

npm start LOG=TRACE // enables both trace and debug logs
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

Output:

> sample-express-server@1.0.0 start
> npm run devserver LOG=trace


> sample-express-server@1.0.0 devserver
> node ./server/node/server.js LOG=trace
