Vite-plugin-debug-js NPM

vite-plugin-debug-js

This is a small plugin for Vite to import the debug package.

It provides a virtual module that sets up the namespace based on the path and file name. Because being lazy is its own reward.

Getting Started

Installation

pnpm add -D vite-plugin-debug-js debug

Then add to your vite.config.ts:

import vitePluginDebug from 'vite-plugin-debug-js';

export default defineConfig({
  plugins: [
    vitePluginDebug(),
  ],
});

Usage

Import and call:

import { debug } from 'virtual:debug-js';

debug("Hello, world!");

// Depending on your environment, you should see something similar to:
//    2023-05-16 13:43:11.1030 vite-app:lib:hello.ts Hello, world!

Types

Add to vite-env.d.ts or anywhere else in the project:

declare module "virtual:debug-js" {
  import { Debugger } from "debug";
  const debug: Debugger;
}

Configuration

The following options can be passed to the plugin:

{
  /** The absolute path to the root of the projecct. This will be used to generate
   *  Ids for Debug, among other things.
   */
  rootDir: string;

  /** The namespace to use for Debug.  */
  debugNamespace: string;

  /** Enable debugging for this namespace to be active. It is also possible to set
   *  this to 'false' and use the standard Debug methods of enabling/disabling.
   */
  debugEnabled: boolean;

  /** Names of path components not to include in the namespace (e.g. 'src')
   */
  stripComponents: string[];
}

The plugin will attempt to choose a sensible default for rootDir, but it is easily confused by things like symlinks.
