debug-logger.ts in Flyde codebase.

In this article, we will review debug-logger.ts in Flyde codebase. We will look at:

1. debugLogger function
2. debug package

debugLogger function

You will find the following code at flyde/core/src/common/debug-logger.ts

import debug from "debug";

const BASE_NS = `flyde`;

const base = debug(BASE_NS);

import type { Debugger as _Debugger } from "debug";

export type DebugLogger = _Debugger;

export const debugLogger = (subNs: string): DebugLogger => {
  return base.extend(subNs);
};

debug is imported and is assigned to base . In the debugLogger function, base is extended with the parameter passed.
