KnowDev Log 🔊

📋 Usage

Installation

npm install --save @knowdev/log

Environment Variables

LOG_LEVEL=all|trace|*debug*|info|warn|error|fatal|silent

Log by Levels

const log = require("@knowdev/log");

log.trace();
log.debug();
log.info();
log.warn();
log.error();
log.fatal();

Logger Class

const { Logger, LOG_LEVEL } = require("@knowdev/log");

const log = new Logger({
  level: LOG_LEVEL.TRACE
})

Conveniences

Log Function, Stand-alone (debug)

const { log } = require("@knowdev/log");

log(message);

Module Logger

Uses silent by default. if process.env.MODULE_LOG_LEVEL is true, follows process.env.LOG_LEVEL. If process.env.MODULE_LOG_LEVEL is also set, uses that log level.

const { moduleLogger } = require("@knowdev/log");

moduleLogger.trace();

Silent Log

Useful to support logging in code but only if an instantiated log object is passed in.

const { silent } = require("@knowdev/log");

silent.fatal(); // Doesn't log

🚀 Deployment

npm publish --access=public
