logboom

logboom —

clearcut simple node logging

• install logboom locally — npm install logboom

• import and instantiate a logger

  import {FileLogger} from "logboom"
  
  const logger = new FileLogger({logfile: "example.log", level: "silly"})
  

• do some logging

  logger.error(new Error("an error occurred"))
  logger.warn("heed my warning!")
  logger.info("something informative")
  logger.verbose("explaining what's happening verbosely")
  logger.debug("information to help diagnose bugs")
  logger.silly("obscenely fine-grained details")
  

• voila! color-coded console output

  

• you also get a color-free example.log text file

notes

• the ConsoleLogger class writes to stdout and stderr

• the FileLogger is really double-logger
  it extends the console logger and writes to the console — but also writes to a text file (with the colors stripped out)

• alternatively, you can just use the ConsoleLogger, and then redirect the stdout/stderr output with unix stuff:
  node myapp 2>&1 | tee -a example.log
  if that's not your jam, just use the file logger
