#Refactoring

Monorepo Refactoring Pipeline

Cross-package refactoring that respects your monorepo boundaries.

The Scenario

Your monorepo has 10+ packages with shared dependencies and patterns. A refactoring that touches a shared library affects every consuming package. Manually updating all consumers is tedious and error-prone. You need coordinated changes across package boundaries.

Who Is This For

Teams working with monorepos (Turborepo, Nx, Lerna) that need to make changes across multiple packages simultaneously. Especially useful for shared library API changes, consistent pattern updates, and cross-package dependency upgrades.

Pipeline Steps

01

Map Package Dependencies

Claude Code

Agent analyzes the monorepo structure, maps inter-package dependencies, and identifies the blast radius of the planned change.

02

Update Shared Library

Claude Code

Agent applies the change to the shared library — new API, updated types, or modified behavior.

03

Update All Consumers

Claude Code

For each consuming package, the agent updates imports, API calls, and types to match the new library interface.

04

Cross-Package Type Check

TypeScript

Full monorepo tsc build to verify type safety across all packages.

05

Run All Test Suites

Test Runner

Every package's test suite runs. Only if all pass does the change proceed to PR.

Expected Results

  • Coordinated changes across 10+ packages in one night
  • Type-safe updates verified across package boundaries
  • All test suites passing before PR creation
  • Single comprehensive PR or per-package PRs — your choice
Estimated Runtime6-10 hours overnight for a 10-20 package monorepo

Frequently Asked Questions

Zowl is tool-agnostic. It works with Turborepo, Nx, Lerna, pnpm workspaces, or any monorepo structure.

Yes. Configure Zowl to update packages in batches — shared library first, then consumers in dependency order over multiple nights.

The dependency mapping step identifies circular dependencies and flags them. Zowl suggests an execution order that minimizes conflicts.
