// Create a basic logger

logger.warn('Warning! Something needs attention');

Output 🎑

Advanced Usage 🔧

Save Logs to File

const logger = logFactory({
    path: './logs/app.log',  // Logs will be saved here
    id: process.pid          // Add process ID to logs
});

logger('This will be saved to the file too!');

Logging Objects

const data = {
    user: 'john',
    age: 25
};

logger('User data:', data);  // Objects are automatically formatted

Disable Console Output

If you want to write logs only to file without console output, use the toStdout option:

const logger = logFactory({
    path: './logs/app.log',
    toStdout: false    // Logs will only be written to file
});

logger('This will only appear in the log file');
logger.info('Silent logging to file');

Output Examples 🎨

When you run your logs, they'll look something like this in the console:

[2024-03-15 10:30:45] - [id:1234] - Hello World
[2024-03-15 10:30:46] - [id:1234] - This is an info message
[2024-03-15 10:30:47] - [id:1234] - Warning! Something needs attention
