Nx Workspace Management

Quick Start

Exploring workspace: nx show projects and nx show project <name> --json Running tasks: nx <target> <project> (e.g., nx build my-app) Affected analysis: nx show projects --affected or nx affected -t <target>

> Note: Prefix commands with npx/pnpx/yarn if nx isn't installed globally.

Core Commands

List and Explore Projects

bash
# List all projects
nx show projects

# Filter by type, pattern, or target
nx show projects --type app
nx show projects --projects "apps/*"
nx show projects --withTarget build

# Find affected projects
nx show projects --affected --base=main

Get Project Information

Critical: Always use nx show project <name> --json for full resolved configuration. Do NOT read project.json directly - it contains only partial configuration.

bash
# Get full configuration
nx show project my-app --json

# Extract targets
nx show project my-app --json | jq '.targets | keys'

Configuration schemas:

• Workspace: node_modules/nx/schemas/nx-schema.json
• Project: node_modules/nx/schemas/project-schema.json

Run Tasks

bash
# Run specific project
nx build web --configuration=production

# Run affected
nx affected -t test --base=main

# View dependency graph
nx graph

Common Workflows

"What's in this workspace?"

bash
nx show projects --type app  # List applications
nx show projects --type lib  # List libraries

"How do I run project X?"

bash
nx show project X --json | jq '.targets | keys'

"What changed?"

bash
nx show projects --affected --base=main

Quick Troubleshooting

• Targets not showing: Use nx show project <name> --json, not project.json
• Affected not working: Ensure git history available (fetch-depth: 0 in CI)
• Cache issues: Run nx reset

For detailed troubleshooting, see reference/best-practices.md.
