📖 Usage

import { createLogger } from 'feature-logger';

export const logger = createLogger();

logger.trace("I'm a trace message!");
logger.log("I'm a log message!");
logger.info("I'm a info message!");
logger.warn("I'm a warn message!");
logger.error("I'm a error message!");

📙 Features

withPrefix()

Adds a static prefix to all log messages, allowing for consistent and easily identifiable log entries.

import { createLogger, withPrefix } from 'feature-logger';

const logger = withPrefix(createLogger(), 'PREFIX');

logger.log('This is a log message.');
// Output: "PREFIX This is a log message."

withTimestamp()

Adds a timestamp to all log messages, enabling you to track when each log entry was created.

import { createLogger, withTimestamp } from 'feature-logger';

const logger = withTimestamp(createLogger());

logger.log('This is a log message.');
// Output: "[MM/DD/YYYY, HH:MM:SS AM/PM] This is a log message."

withMethodPrefix()

Adds the log method name as a prefix to all log messages, allowing you to easily identify the log level or method used.

import { createLogger, withMethodPrefix } from 'feature-logger';

const logger = withMethodPrefix(createLogger());

logger.log('This is a log message.');
// Output: "Log: This is a log message."

logger.error('This is an error message.');
// Output: "Error: This is an error message."
