CKN Technology Core – Log Extensions

Import

To load and enable the custom Log extensions described on this page, import the core package once at the entry point of your application (or any module that runs during startup).

import "@ckn-technology/core";

Once imported, the Log utilities are available globally for all code that uses the Log class.

Constructor

`constructor(...prefixs)`

Description
Creates a new Log instance with one or more prefixes. These prefixes will be printed before all log messages from this instance, making it easy to trace logs by module, context, or subsystem.

const log = new Log("[APP]", "[USER]");

Methods

`info(...msg)`

Example

const log = new Log("[SERVER]", "[INFO]");
log.info("Server started", "port:", "8080");

`error(...msg)`

Description
Logs an error message using console.error with:

Timestamp from dateTimeDataFormat()
