Features

Default devel is INFO

import LogUtil from "zhi-log"

const logger = LogUtil.defaultLogFactory().getLogger()
logger.debug("This is debug log")
logger.info("This is info log")
logger.error("This is error log")

// [zhi] [11:26:51] INFO /Users/terwer/Documents/mydocs/zhi-log/test/log.test.ts:33:48 : This is info log
// [zhi] [11:26:51] ERROR /Users/terwer/Documents/mydocs/zhi-log/test/log.test.ts:33:48 : This is error log

You can set a custom log level

import LogUtil from "zhi-log"

const logger = LogUtil.customLogFactory(LogLevelEnum.LOG_LEVEL_DEBUG).getLogger("test")
logger.debug("This is debug log")
logger.info("This is info log")
logger.error("This is error log")

// [zhi] [11:28:15] DEBUG test : This is debug log
// [zhi] [11:28:15] INFO test : This is info log
// [zhi] [11:28:15] ERROR test : This is error log

You can also set a custom prefix sign

import LogUtil from "zhi-log"

const logger = LogUtil.customLogFactory(LogLevelEnum.LOG_LEVEL_DEBUG, "my-log").getLogger("test")
logger.debug("This is debug log")
logger.info("This is info log")
logger.error("This is error log")

// [my-log] [11:29:04] DEBUG test : This is debug log
// [my-log] [11:29:04] INFO test : This is info log
// [my-log] [11:29:04] ERROR test : This is error log

Also, if you config LOG_LEVEL in your project's .env file, it will work

LOG_LEVEL=DEBUG
DEFAUT_LOGGER=zhi
