# Nx Workspace Patterns

Production patterns for Nx monorepo management.

## Do not use this skill when

- The task is unrelated to nx workspace patterns
- You need a different domain or tool outside this scope

## Instructions

- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
- If detailed examples are required, open `resources/implementation-playbook.md`.

## Use this skill when

- Setting up new Nx workspaces
- Configuring project boundaries
- Optimizing CI with affected commands
- Implementing remote caching
- Managing dependencies between projects
- Migrating to Nx

## Core Concepts

### 1. Nx Architecture

```
workspace/
├── apps/              # Deployable applications
│   ├── web/
│   └── api/
├── libs/              # Shared libraries
│   ├── shared/
│   │   ├── ui/
│   │   └── utils/
│   └── feature/
│       ├── auth/
│       └── dashboard/
├── tools/             # Custom executors/generators
├── nx.json            # Nx configuration
└── workspace.json     # Project configuration
```

### 2. Library Types

| Type | Purpose | Example |
|------|---------|---------|
| **feature** | Smart components, business logic | `feature-auth` |
| **ui** | Presentational components | `ui-buttons` |
| **data-access** | API calls, state management | `data-access-users` |
| **util** | Pure functions, helpers | `util-formatting` |
| **shell** | App bootstrapping | `shell-web` |

## Templates

### Template 1: nx.json Configuration

```json
{
  "$schema": "./node_modules/nx/schemas/nx-schema.json",
  "npmScope": "myorg",
  "affected": {
    "defaultBase": "main"

      }
    }
  },
