Usage

Basic Setup

First, import the logger and start logging:

import { clientLogger, serverLogger } from 'logify-fa';

// Example of client-side logging
clientLogger.info("This is an info message from the client");

// Example of server-side logging
serverLogger.warn("This is a warning message from the server");

Log Levels

logify-fa supports four log levels, each with its own color for easy identification:

• debug: Blue
• info: Green
• warn: Yellow
• error: Red

You can control the minimum log level output by setting the level in the logger's constructor:

import { clientLogger } from 'logify-fa';
// Only logs 'warn' and 'error' messages
const logger = new clientLogger("warn");
logger.debug("This debug message will not be logged");
logger.error("This error message will be logged");

Logging with Metadata

You can attach metadata to your log messages for more detailed logging:

clientLogger.debug("Debugging info", { userId: 123, operation: "update" });
serverLogger.error("Error occurred", { errorCode: 500, errorMessage: "Internal Server Error" });

Persian Date in Logs

All log messages automatically include the current date in the Persian calendar:

clientLogger.info("This is an info message");
// Output: [1402-12-11] [INFO]: This is an info message

Configuration

logify-fa can be configured to match your specific logging requirements:

• Log Level: Set the minimum log level to display (default is info).
• Metadata: Include additional data with each log entry.
• Persian Date: Automatically adds Persian date formatting to each log entry.
