# Nx Commands Reference

Complete command reference with advanced options and patterns.

## Project Listing

### Basic Listing

```bash
# List all projects
nx show projects

# Output as JSON
nx show projects --json
```

### Filtering by Type

```bash
# List applications
nx show projects --type app

# List libraries
nx show projects --type lib

# List e2e projects
nx show projects --type e2e
```

### Filtering by Pattern

```bash
# Glob pattern matching
nx show projects --projects "apps/*"
nx show projects --projects "shared-*"

# Multiple patterns (comma-separated)
nx show projects --projects "apps/*,libs/shared/*"
```

### Filtering by Target

```bash
# Projects with build target
nx show projects --withTarget build

# Projects with e2e target
nx show projects --withTarget e2e

# Projects with test target
nx show projects --withTarget test
```

### Filtering by Affected

```bash
# Affected since default base
nx show projects --affected

# Affected with explicit base
nx show projects --affected --base=main
nx show projects --affected --base=origin/main

# Affected between two commits
nx show projects --affected --base=abc123 --head=def456

# Affected by uncommitted changes
nx show projects --affected --uncommitted

# Affected by untracked files
nx show projects --affected --untracked
```

### Combining Filters

```bash
# Affected libraries with test target
nx show projects --affected --type lib --withTarget test

# Affected apps, excluding e2e
nx show projects --affected --type app --exclude="*-e2e"

# Libraries in specific scope
nx show projects --type lib --projects "libs/web/*"
```

## Project Configuration

### Get Project Information

```bash
# Full resolved configuration
nx show project my-app --json

# Pretty print with jq

nx show project my-app --json | jq '.targets | keys'
nx show project my-app --json | jq '.targets.build'
nx show project my-app --json | jq '.sourceRoot'
nx show project my-app --json | jq '.tags'
```

### Schema References

```bash
# Read workspace schema
cat node_modules/nx/schemas/nx-schema.json | jq '.properties | keys'

# Read project schema
cat node_modules/nx/schemas/project-schema.json | jq '.properties | keys'
```

## Generator Commands

### Generate Library

```bash
# React library
nx g @nx/react:lib my-lib

# With directory
nx g @nx/react:lib my-lib --directory=libs/shared

# With tags

  --directory=libs/web \
  --tags=type:feature,scope:web

# Dry run
nx g @nx/react:lib my-lib --dry-run
```

### Generate Application

```bash
# React app
nx g @nx/react:app my-app

# Next.js app
nx g @nx/next:app my-app

# With tags and routing
nx g @nx/react:app my-app \
  --tags=type:app,scope:web \
  --routing
```

```

## Workspace Analysis

### Find Dependencies

```bash
# Find what depends on a library
grep -r "from '@myorg/my-lib'" --include="*.ts" --include="*.tsx" apps/ libs/

# Find imports in specific project
grep -r "from '@myorg/" apps/my-app/src --include="*.ts"
```

### Analyze Project Root

```bash
# Find project root
nx show project my-app --json | jq '.root'

# List all project roots
nx show projects --json | jq '.[] | {name, root}'
```

### Check Affected Reason
