ohta

A microservice logging library inspired by Ohta and Fukuisan banter from Iron Chef Japan

Install

npm i ohta

What does it do?

Ohta logs events within Javascript programs, creates individual .log files for info and error logs

Potential Use Cases

• I want to log events within Docker microservice and export log levels into individual files.
• I have an API and I want to track response times.
• I want to track events across my Docker architecture and follow logs in real-time remotely.

Log Specification

fukuisan.askOhtaAbout(LOG_LEVEL, 'SERVICE', 'OPERATION', 'MESSAGE');

• LOG_LEVEL: Log level (info or error)
• SERVICE: The name of your microservice or application
• OPERATION: Name of action happening within the application (i.e. function call, API request, server start, etc.)
• MESSAGE: Message defining what the OPERATION is doing

How does this work?

1. Fukuisan summons Ohta

const fukuisan = require("ohta");

2. Fukuisan asks Ohta to describe what the chefs are cooking in Kitchen Stadium

fukuisan.askOhtaAbout('info', 'API', 'pullMapData', 'REQUEST');

3. Ohta describes what the chefs are cooking in Kitchen Stadium

{
  "level": "info",
  "message": "The chef is whisking thick cream with shallots, purreed mangoes and a lobster prawn sauce",
  "operation": "whiskingCream",
  "requestId": "3de0c9f06cf61470b22bd6eedcb2a6105e64144c",
  "service": "chefBattle",
  "timestamp": "2023-03-27T23:37:25.488Z"
}
