Log Levels

mime-logger has three log levels, each with its own color and intended severity.

Methods

const logger = new Logger("app");

logger.info("Server ready");
logger.warn("High memory usage");
logger.error("Disk write failed");

Field	Type	Required	Description
info(message, ...args)	void	optional	Informational messages. Label rendered in green.
warn(message, ...args)	void	optional	Non-fatal warnings. Label rendered in yellow.
error(message, ...args)	void	optional	Errors and failures. Label rendered in red.

Message colors also follow the level: info → cyan, warn → yellow, error → red.

LogLevel enum

The LogLevel enum is exported for use with the low-level log() method and custom format functions.

import { LogLevel } from "mime-logger";

LogLevel.INFO   // "info"
LogLevel.WARN   // "warn"
LogLevel.ERROR  // "error"

Low-level log()

log() is the method all three convenience methods delegate to. Use it when the level is determined at runtime.

logger.log(LogLevel.WARN, "Threshold exceeded: %s%%", 95);

log(level: LogLevel, message: string, args: any[]): void

Field	Type	Required	Description
level	LogLevel	required	Log level to use.
message	string	required	Message string. Use %s as a placeholder for args.
args	any[]	required	Values to interpolate into %s placeholders.

Note

log() takes args as an array, not rest parameters. Pass an empty array [] if you have no arguments.
