SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill standardizes and stabilizes CI for Nx monorepos by orchestrating affected-project detection and per-project build/test/render pipelines, ensuring consistent gating and artifact handling across teams.

Core Features & Use Cases

  • Detects affected projects with Nx to minimize work and accelerate pipelines.
  • Enforces deterministic execution by gating steps on affected outputs and project scopes.
  • Supports renderable artifact workflows (e.g., diagrams, docs) through a structured pipeline.

Quick Start

Clone this repository and run the provided setup to enable Nx-based CI workflows in your monorepo.

FAQPage Schema
How do I set up CI for an Nx monorepo to only build and test affected projects?

To set up CI for an Nx monorepo, this Skill automates affected-project detection and orchestrates per-project build and test pipelines. It minimizes work by gating execution on affected outputs, ensuring deterministic CI workflows.

What is deterministic CI gating for Nx monorepos and how does it work?

Deterministic CI gating for Nx monorepos enforces consistent execution by validating affected outputs and project scopes. This Skill applies a three-layer pipeline covering detection, execution, and aggregation to standardize artifact handling.

Can I handle renderable artifacts like diagrams or docs in a GitHub Actions Nx pipeline?

Yes, you can handle renderable artifacts in a GitHub Actions Nx pipeline. This Skill supports renderable artifact workflows through a structured pipeline, orchestrating per-project execution and artifact aggregation for outputs like diagrams and docs.

Do I need to modify my .github/workflows directory to use automated Nx pipeline detection?

Yes, you need to modify your .github/workflows directory. This Skill applies to workflows that modify .github/workflows files, add new Nx projects, or update CI pipelines to provide deterministic gating and artifact handling.

What is the best way to structure a CI pipeline for Nx monorepos to accelerate builds?

The best way to structure a CI pipeline for Nx monorepos is using a three-layer architecture: detection, execution, and aggregation. This Skill orchestrates affected-project detection to minimize work and accelerate builds.

Why does my Nx monorepo CI run unnecessary tests across unaffected projects?

Your Nx monorepo CI runs unnecessary tests because it lacks affected-project detection. This Skill solves the problem by detecting affected Nx projects and gating steps on affected outputs to minimize pipeline work.
