Monorepo Release Script with Build Metadata

Build a Node.js script that performs version releases for a monorepo and attaches build metadata to the released versions.

Overview

Your task is to create a release automation script for a monorepo that can bump package versions and add custom build metadata (such as CI build numbers or git commit SHAs) to the version numbers in a semver-compatible format.

Requirements

The script should:

• Accept a version bump type: patch, minor, or major
• Optionally accept build metadata via a --build-metadata flag
• Perform the version bump for packages in the monorepo
• When build metadata is provided, append it to the version with a + prefix (e.g., 1.2.3+build.456)
• Log the resulting version numbers to the console

Example Usage

# Basic patch release
node release.js patch

# Minor release with build number
node release.js minor --build-metadata build.123

# Major release with git commit SHA
node release.js major --build-metadata sha.abc1234

Test Cases

• Executing a patch bump without build metadata successfully increments the patch version @test
• Executing a minor bump with --build-metadata build.123 produces a version ending in +build.123 @test
• Executing a major bump with --build-metadata ci.456.abc789 produces a version ending in +ci.456.abc789 @test
