Nx Workspace Patterns

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
