SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and examples (resource) components.

What problem does it solve?

This Skill simplifies the management of complex monorepos by providing a unified system for task orchestration, caching, and toolchain management, significantly speeding up development and CI processes.

Core Features & Use Cases

Task Orchestration: Define and run tasks across multiple projects with intelligent dependency management.
Build Caching: Cache build artifacts to accelerate local and CI builds.
Toolchain Management: Standardize Node.js, Rust, Python, and other toolchain versions across the monorepo.
CI Optimization: Efficiently run only affected tasks in CI environments.
Use Case: Automatically set up a new monorepo, define build and test tasks for different projects, and configure CI to only run necessary checks on code changes.

Quick Start

Configure moon for a new monorepo project.

FAQPage Schema

How do I manage tasks and build caching in a polyglot monorepo?▼

Manage polyglot monorepos by orchestrating tasks and caching build outputs using configuration files like .moon/workspace.yml and moon.yml. This unifies toolchain versions and standardizes build processes across multiple projects to accelerate local development.

How does affected detection optimize CI pipelines for monorepos?▼

Affected detection optimizes CI pipelines by analyzing the project graph to efficiently run only the tasks impacted by recent code changes. This prevents executing unnecessary checks across the entire monorepo, significantly reducing CI runtime.

Can I standardize different toolchain versions across multiple projects in a monorepo?▼

Yes, you can standardize Node.js, Rust, Python, and other toolchain versions across a monorepo. This toolchain management ensures consistent environments for all contributors and eliminates version drift between local development and CI.

What is the best way to visualize project dependencies in a complex monorepo?▼

The best way to visualize project dependencies is by generating a project graph. This maps task dependencies and project relationships, providing a clear overview of the monorepo structure to help orchestrate builds and troubleshoot bottlenecks.

Do I need specific configuration files to set up monorepo task orchestration?▼

Yes, you need a .moon/workspace.yml file for workspace-level settings and moon.yml files for project-specific configurations. These files define task dependencies, build pipelines, and toolchain requirements to properly orchestrate tasks.

Why are my monorepo CI builds slow and running unnecessary tasks?▼

Monorepo CI builds run slowly when every pipeline executes all tasks regardless of changes. Implementing intelligent task orchestration with affected detection and build caching limits CI runs to only modified projects and reuses cached artifacts.
