# Turborepo Caching Production patterns for Turborepo build optimization. ## When to Use This Skill - Setting up new Turborepo projects - Configuring build pipelines - Implementing remote caching - Optimizing CI/CD performance - Migrating from other monorepo tools - Debugging cache misses ## Core Concepts ### 1. Turborepo Architecture ``` Workspace Root/ ├── apps/ │ ├── web/ │ │ └── package.json │ └── docs/ │ └── package.json ├── packages/ │ ├── ui/ │ │ └── package.json │ └── config/ │ └── package.json ├── turbo.json └── package.json ``` ### 2. Pipeline Concepts | Concept | Description | | -------------- | -------------------------------- | | **dependsOn** | Tasks that must complete first | | **cache** | Whether to cache outputs | | **outputs** | Files to cache | | **inputs** | Files that affect cache key | | **persistent** | Long-running tasks (dev servers) | ## Templates ### Template 1: turbo.json Configuration ```json { "$schema": "https://turbo.build/schema.json", "globalDependencies": [".env", ".env.local"], "globalEnv": ["NODE_ENV", "VERCEL_URL"], "pipeline": { "build": { "dependsOn": ["^build"], "outputs": ["dist/**", ".next/**", "!.next/cache/**"], "env": ["API_URL", "NEXT_PUBLIC_*"] }, "test": { "dependsOn": ["build"], "outputs": ["coverage/**"], "inputs": ["src/**/*.tsx", "src/**/*.ts", "test/**/*.ts...
