SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automate the creation, testing, and maintenance of GitHub Actions workflows across an Nx monorepo using standardized patterns and templates.

Core Features & Use Cases

Composite action pattern: centralizes setup for workflows via a reusable action to reduce boilerplate.
Workflow templates and guidance: provides minimal templates for common tasks (lint, test, typecheck, format) and practical usage patterns.
Nx integration & troubleshooting: guides on using nx affected, fetch-depth 0 and best practices for reliable CI.

Quick Start

Create a new workflow by following the provided template and use the composite action to initialize pnpm and Node.js, then run nx affected to target lint and tests.

FAQPage Schema

How do I set up GitHub Actions workflows for an Nx monorepo?▼

Setting up GitHub Actions workflows for an Nx monorepo involves using a composite action to initialize pnpm and Node.js, then running nx affected to execute lint, test, and typecheck tasks across affected projects.

What is the composite action pattern in GitHub Actions?▼

The composite action pattern in GitHub Actions centralizes monorepo setup into a reusable action, reducing boilerplate by standardizing Node.js, pnpm, and Nx SHA configurations across multiple workflow templates.

Why does nx affected fail to detect changes in my GitHub Actions workflow?▼

nx affected fails to detect changes when git history is incomplete. You must configure fetch-depth 0 in your GitHub Actions workflow to ensure full history is available for accurate Nx affected computation.

Can I use standardized workflow templates for lint, test, and typecheck in GitHub Actions?▼

Yes, you can use standardized minimal workflow templates for lint, test, typecheck, and format tasks in GitHub Actions. These templates integrate with a composite setup action to provide consistent CI pipelines across your Nx projects.

How do I manage centralized versions for GitHub Actions in a monorepo?▼

Manage centralized versions for GitHub Actions by consolidating environment setup into a single composite action. This standardizes Node.js, pnpm, and Nx configurations, ensuring consistent versions across all workflow templates.

Do I need pnpm to use composite actions for Nx monorepos?▼

pnpm is required for the Nx monorepo composite action setup pattern. The reusable action specifically initializes pnpm alongside Node.js to manage dependencies and execute standardized workflow tasks.
