Levels

Levels are prioritized entities to separate log messages by semantic. You can cover yout code with logging different depth and if you want to run your app on production mode you will not see debug log level. These are default log levels of LogX:

• silly: chalk.white
• debug: chalk.green
• info: chalk.magenta
• warning: chalk.yellow
• error: chalk.red
• special: chalk.cyan.underline
• critical: chalk.red.underline.bold

json

Every level logging function has .json property.

logger.warning.json('API', 'Payments', 'v3.2', 'Health check failed', {"reward":128.23,"instances":2,"availableApis":[{"host":"127.0.0.1","port":8888},{"host":"127.0.0.1","port":8889}],"healthCheck":false})

Will produce:
