Installation

You can install the package using npm:

npm install @avocajs/logger

Usage

Importing the Logger

First, import the Logger class from the package:

import { Logger } from "@avocajs/logger";

Creating a Logger Instance

Create an instance of the Logger class by providing the path to the log file:

const logger = new Logger("./path/to/logfile.log");

Logging Messages

Use the log method to log messages to the specified log file. The log method returns a promise that resolves when the message is successfully logged:

logger
  .log("This is a log message")
  .then(() => console.log("Message logged successfully"))
  .catch((error) => console.error("Error logging message:", error));

Setting the Log File Path

You can change the log file path using the setPath method:

logger.setPath("./new/path/to/logfile.log");

Getting the Log File Path

You can retrieve the current log file path using the getPath method:

const logFilePath = logger.getPath();
console.log("Current log file path:", logFilePath);
