LogFlex

A flexible logging utility for Node.js with support for TXT, CSV, JSON formats, and more.

Installation

npm install LogFlex

Usage

Basic Usage

By default, the library logs data to a text file (log.txt) in the logs directory:

import { LogFlex } from 'LogFlex';

LogFlex('This is a log message');

Custom File Path

You can specify a custom file path for the log file:

LogFlex('This is a log message in a custom file', {
  filePath: './logs/custom-log'
});

Logging to a CSV File

To log data in CSV format, set the fileType option to 'csv':

LogFlex('This is a log message in CSV', {
  filePath: './logs/custom-log',
  fileType: 'csv'
});

Custom Date Format and Log Level

You can customize the date format and log level:

LogFlex('This is a custom log message', {
  filePath: './logs/custom-log',
  dateFormat: 'yyyy/MM/dd HH:mm',
  logLevel: 'error'
});

Options

• filePath: Path to the log file (default: ./logs/log)
• dateFormat: Format for the timestamp (default: yyyy-MM-dd HH:mm:ss)
• logLevel: Log level (info, warning, error) (default: info)
• fileType: File type (txt or csv) (default: txt)

Log File Formats

TXT Format

When logging to a TXT file, the log entries will be in the following format:

Timestamp    Level    Message
[2024-07-07 12:34:56] [INFO] This is a log message

CSV Format

"Timestamp","Level","Message"
"2024-07-07 12:34:56","INFO","This is a log message"

// Log to a CSV file
LogFlex('This is a log message in CSV', {
  filePath: './logs/custom-log',

});
