Monorepo Dependency Version Updater

Build a tool that automatically updates dependency versions across packages in a monorepo when package versions change. The tool should identify which packages depend on updated packages and synchronize their dependency declarations.

Capabilities

Dependent Package Discovery

• Given a monorepo with package-b depending on package-a, when querying dependents of package-a, the tool returns ["package-b"] @test
• Given a package with no dependents in the monorepo, the tool returns an empty array @test

Cross-Package Version Updates

• Given package-a at version 1.0.0 that is updated to 2.0.0, and package-b that depends on package-a, when synchronizing versions, package-b's dependency is updated to reference ^2.0.0 @test
• Given multiple packages depending on package-a, when package-a's version is updated, all dependent packages' dependencies are updated to the new version @test

Batch Version Management

• Given a monorepo with 5 packages, when performing a "minor" version bump on all packages, each package version is incremented by 0.1.0 @test
• Given changed packages in a monorepo, when requesting version updates only for changed packages, only those packages are versioned @test

/**
 * Finds all packages in the monorepo that depend on the specified package
 * @param {string} packageName - The name of the package to check
 * @returns {Promise<string[]>} Array of dependent package names
 */
async function findDependents(packageName) {
  // IMPLEMENTATION HERE
}

/**
 * Synchronizes dependency version references across packages after a version update
 * @param {string} packageName - The package that was updated
 * @param {string} newVersion - The new version of the package
 * @returns {Promise<void>}
 */
async function syncDependencyVersions(packageName, newVersion) {
  // IMPLEMENTATION HERE
}

/**
 * Performs version bumping on packages in the monorepo
 * @param {Object} options - Version bump options
 * @param {string} options.bump - Version bump type: 'major', 'minor', or 'patch'
 * @param {boolean} options.changedOnly - If true, only version packages with changes since last release
 * @returns {Promise<Map<string, string>>} Map of package names to their new versions
 */

  // IMPLEMENTATION HERE
}
