🏄‍♀️ Usage

Example of defining a package manager for the current project

import { defineManager } from 'pubun';

async function demoFunction() {
  const packageManager = await defineManager('/path/to/project');

  console.log(packageManager); // npm | yarn | pnpm | bun
}

demoFunction();

Example of detecting all globally installed package managers

import { defineGlobalManagers } from 'pubun';

async function demoFunction() {
  const globalManagers = await defineGlobalManagers();

  console.log(globalManagers);
  // [
  //   {
  //     manager: 'pnpm';
  //     version: '8.11.0';
  //   },
  //   {
  //     manager: 'bun';
  //     version: '1.0.14';
  //   },
  //   ...
  // ]
}

demoFunction();

Clearing Pubun cache

Since all Pubun operations are cached in order to optimize speed, sometimes you may need to clear the cache manually.

import { clearCache } from 'pubun';

clearCache();

📜 API

defineManager()

Defines the package manager used in a given directory.
Checks for the presence of characteristic files (e.g., package-lock.json for npm) for each known package manager.

Supported package managers: npm, yarn, pnpm, bun

type PackageManager = 'npm' | 'yarn' | 'pnpm' | 'bun';

defineManager: (path?: string) => Promise<PackageManager | null>;

Argument	Type	Default value	Description
path	string	process.cwd()	The path to the directory to check. If not provided, defaults to the current working directory.

Return: A promise that resolves to the type of package manager used or null if no package manager can be defined.

defineGlobalManagers()

interface GlobalManagerData {
  manager: PackageManager;
  version: string;
}

defineGlobalManagers: () => Promise<GlobalManagerData[] | null>;

Return: A promise that resolves to an array of global manager data, including the name and version of each installed package manager, or null if none is installed.

clearCache()

Clears the entire cache.
This function removes all cached data related to package manager checks. Useful for resetting the state to ensure fresh data is fetched.

clearCache: () => void
