Logging Configuration Guide

Overview

TimeSafari now supports configurable logging levels via the VITE_LOG_LEVEL environment variable. This allows developers to control the verbosity of console output without modifying code.

Available Log Levels

Level	Value	Description	Console Output
`error`	0	Errors only	Critical errors only
`warn`	1	Warnings and errors	Warnings and errors
`info`	2	Info, warnings, and errors	General information, warnings, and errors
`debug`	3	All log levels	Verbose debugging information

Environment Variable

Set the VITE_LOG_LEVEL environment variable to control logging:

# Show only errors
VITE_LOG_LEVEL=error

# Show warnings and errors (default for production web)
VITE_LOG_LEVEL=warn

# Show info, warnings, and errors (default for development/capacitor)
VITE_LOG_LEVEL=info

# Show all log levels including debug
VITE_LOG_LEVEL=debug

Default Behavior by Platform

The logger automatically selects appropriate default log levels based on your platform and environment:

Production Web: warn (warnings and errors only)
Electron: error (errors only - very quiet)
Development/Capacitor: info (info and above)

Usage Examples

Setting Log Level in Development

# In your terminal before running the app
export VITE_LOG_LEVEL=debug
npm run dev

# Or inline
VITE_LOG_LEVEL=debug npm run dev

Setting Log Level in Production

# For verbose production logging
VITE_LOG_LEVEL=info npm run build:web

# For minimal production logging
VITE_LOG_LEVEL=warn npm run build:web

Programmatic Access

The logger provides methods to check current configuration:

import { logger } from '@/utils/logger';

// Get current log level
const currentLevel = logger.getCurrentLevel(); // 'info'

// Check if a level is enabled
const debugEnabled = logger.isLevelEnabled('debug'); // false if level < debug

// Get available levels
const levels = logger.getAvailableLevels(); // ['error', 'warn', 'info', 'debug']

Database Logging

Database logging continues to work regardless of console log level settings. All log messages are still stored in the database for debugging and audit purposes.

Migration Notes

Existing code: No changes required - logging behavior remains the same
New feature: Use VITE_LOG_LEVEL to override default behavior
Backward compatible: All existing logging calls work as before

Best Practices

Development: Use VITE_LOG_LEVEL=debug for maximum visibility
Testing: Use VITE_LOG_LEVEL=info for balanced output
Production: Use VITE_LOG_LEVEL=warn for minimal noise
Debugging: Temporarily set VITE_LOG_LEVEL=debug to troubleshoot issues

Troubleshooting

No Logs Appearing

Check your VITE_LOG_LEVEL setting:

echo $VITE_LOG_LEVEL

Too Many Logs

Reduce verbosity by setting a lower log level:

VITE_LOG_LEVEL=warn

Platform-Specific Issues

Remember that Electron is very quiet by default. Use VITE_LOG_LEVEL=info to see more output in Electron builds.
