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"
Example
import { LogFlex } from 'LogFlex';
// Log to a text file
LogFlex('This is a log message');
// Log to a CSV file
LogFlex('This is a log message in CSV', {
filePath: './logs/custom-log',

});
// Log to a custom text file
LogFlex('This is a custom log message', {
