Logger Levels

Logger Level Heirarchy

• Setting a higher level will hide the lower level logs

DEBUG < INFO < WARN < ERROR < SILENT

Setting a Logger Level

import { createLogger, LogLevel } from "spartan-logger";

const logger = createLogger();
logger.setLevel(LogLevel.WARN);
logger.setLevel(LogLevel.DEBUG);

The default logger level is INFO

logger.debug("This is a DEBUG message");
logger.info("Hello, World!");
logger.error("This is an error message");
