Monorepo Management

Use Turborepo, Nx, and pnpm workspace to master monorepo management, build efficient and scalable multi-package repositories, and achieve optimized build processes and dependency management.

Skill Overview

Help developers set up and manage a single code repository (monorepo), supporting coordinated development of multiple packages and applications within one project. Enable code sharing, a unified toolchain, and atomic commits.

Use Cases

Setting up a new monorepo project

Build a multi-package repository from scratch, choose the right tools (Turborepo/Nx/pnpm workspace), configure the workspace, and set up shared dependencies.

Migrating from multiple repositories to a monorepo

Consolidate existing standalone projects into a single code repository, keep the Git history, and adjust dependency relationships and build workflows.

Optimizing build and test performance

Significantly shorten CI/CD time and improve developer efficiency through incremental builds, smart caching, and parallel execution.

Core Features

Integration with mainstream tools

Supports three major approaches: Turborepo, Nx, and pnpm workspace, providing configuration templates and best practices for each tool.

Dependency and build management

Centralize cross-package dependency management, configure incremental builds and caching mechanisms, and implement an efficient strategy of “only building changed packages.”

Team collaboration support

Offers code-sharing strategies, atomic commit conventions, and CI/CD configuration solutions to support collaborative development in large teams.

Common Questions

What is a monorepo? How is it different from a typical project?

A monorepo (single code repository) is an architectural pattern that manages multiple related packages, applications, or projects within the same Git repository. Compared with a typical project, its main difference is that it can manage multiple independent packages (e.g., frontend apps, backend services, shared component libraries, etc.) within one repository. All packages use the same dependency versions and toolchain, and code can be referenced directly between packages without publishing to npm. This makes cross-package refactoring easier, because all changes can be committed atomically.

Should I choose Turborepo, Nx, or pnpm workspace?

It depends on project scale and requirements:

pnpm workspace: A lightweight choice suitable for small to medium projects; saves disk space via symlinks and is simple and straightforward to configure.

Turborepo: Focused on build performance; uses incremental builds and remote caching, making it suitable for projects with frequent CI/CD.

Nx: The most feature-complete option; provides code generation, visual dependency graphs, automatic affected-project inference, and other advanced capabilities—ideal for large enterprise projects.

Many teams also combine them—for example, use pnpm workspace to manage dependencies and Turborepo to optimize builds.

How do I migrate existing multi-repository projects to a monorepo?

Migration is recommended in phases: 1) create a new monorepo repository and use git subtree or git-filter-repo to preserve original repository history; 2) organize directory structure by feature or layer (e.g., apps/ for applications and packages/ for shared packages); 3) adjust package dependency relationships to switch from npm dependencies to internal workspace references; 4) configure unified build scripts and CI/CD workflows. Throughout the process, it’s recommended to first migrate non-core projects to validate the workflow, then gradually migrate core business applications.
