Monorepo Task Runner

Build a command-line tool that runs tasks across multiple packages in a monorepo with filtering and output aggregation capabilities.

Requirements

Your tool should:

1. Execute a specified npm script across all packages in a monorepo
2. Support filtering packages by name pattern (scope)
3. Support excluding specific packages from execution (ignore)
4. Return results indicating which packages succeeded or failed

The tool accepts:

• A script name to execute (e.g., "build", "test", "lint")
• Optional scope patterns to include specific packages
• Optional ignore patterns to exclude specific packages
• Optional working directory path

The tool returns:

• Overall success status
• Results array with per-package execution outcomes

Test Cases

• Running a script across all packages without filters succeeds and executes in all packages @test
• Running a script with scope filter only executes in matching packages @test
• Running a script with ignore filter excludes specified packages @test
• Running a script that fails in one package reports the failure correctly @test

API

/**
 * Executes an npm script across multiple packages in a monorepo
 *
 * @param {string} scriptName - The npm script to run (e.g., "build", "test")
 * @param {Object} options - Configuration options
 * @param {string[]} [options.scope] - Package name patterns to include
 * @param {string[]} [options.ignore] - Package name patterns to exclude
 * @param {string} [options.cwd] - Working directory containing the monorepo
 * @returns {Promise<{success: boolean, results: Array<{package: string, success: boolean, error?: string}>}>}
