Workspace Dependency Manager

A utility library that provides package manager detection and dependency management functionality for monorepo workspaces. The library should automatically detect which package manager is being used in a workspace and provide methods to manage dependencies appropriately.

Capabilities

Package Manager Detection

  • It detects the package manager being used in the current workspace @test
  • It returns the correct package manager when a lock file exists @test

Dependency Addition

  • It adds dependencies to package.json with correct formatting @test
  • It preserves existing dependencies when adding new ones @test

Installation Task Generation

  • It generates an installation task for the detected package manager @test

Implementation

@generates

API

import { Tree } from '@nx/devkit';

/**
 * Detects the package manager used in the workspace.
 *
 * @param workspaceRoot - The root directory of the workspace
 * @returns The detected package manager ('npm', 'yarn', 'pnpm', or 'bun')
 */
export function detectWorkspacePackageManager(workspaceRoot: string): string;

/**
 * Adds dependencies to the workspace's package.json.
 *
 * @param tree - The file system tree
 * @param dependencies - Object mapping package names to version strings
 * @param devDependencies - Object mapping dev package names to version strings
 * @returns A callback function to install the added packages

export function addDependencies(
  tree: Tree,
  dependencies: Record<string, string>,
  devDependencies?: Record<string, string>
