NextJs Logging Wrapper

This logging wrapper goal is to standardize the records written by our NextJs services.

How to

To use this package three steps are needed:

• add "nextjs-logging-wrapper": "*", to your dependencies
• based on the needs, you can use one of the two available methods:
  • getServerLogger(), that must be used to log entries on the server side
  • getClientLogger(), used to log entries on the client side

Server example

import { getServerLogger } from "nextjs-logging-wrapper";
.....
"use server"
.....
getServerLogger().debug("Welcome to the server side!");

Client example

"use client"
import { getClientLogger } from "nextjs-logging-wrapper";
.....
getClientLogger().debug("Welcome to the client side!");

Log entries format

Client Side

The entry for the client logger will be something similar to

{"level":30,"level_name":"INFO","timestamp":1719322306071,"request":{"path":"/en/the-page","params":{"locale":"en"},"query_params":{}},"message":"Welcome to the client side"}

Server Side

The entry for the server logger will be something similar to

 {"level":30,"level_name":"INFO","hostname":"SSalvatico-ITMAC24","timestamp":1719323762474,"request_id":"50572f1b-a789-459d-9770-c525b69a221e","request":{"scheme":"http","method":"GET","path":"/en/the-backend-route","hostname":"localhost:3002","language":"en","user_agent":"the user agent"},"message":"Welcome to the server side"}

Minimum Log Level

The minimum log level is decided, in order of priority, by:

• optional minimumLevel parameter passed when the logger instance is created
• LOG_LEVEL env variable
• otherwise debug is set as default value
