What is Turborepo?

Turborepo is a high-performance build system designed for JavaScript and TypeScript monorepos. It intelligently caches build outputs and runs tasks in parallel, dramatically speeding up CI/CD pipelines and local development. Frontend Accelerator can be configured to work with Turborepo for multi-package projects.

Turborepo features:

• Smart caching: Never rebuild the same code twice with remote and local caching
• Parallel execution: Runs tasks across multiple packages simultaneously
• Task pipelines: Define dependencies between tasks for optimal build order
• Remote caching: Share build cache across team members and CI environments
• Incremental builds: Only rebuild what changed since last build

Turborepo configuration example:

// turbo.json
{
  "pipeline": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": [".next/**", "!.next/cache/**"]
    },
    "test": {
      "dependsOn": ["build"],
      "cache": false
    },
    "lint": {
      "cache": false
    }
  }
}

Monorepo structure example:

/apps/web (Frontend Accelerator app)
/apps/mobile
/packages/ui (shared components)
/packages/config (shared config)

Key benefits:

• 10x faster builds: Smart caching and parallelization dramatically reduce build times
• Team collaboration: Remote caching shares build artifacts across developers
• Scalability: Handles monorepos with dozens of packages efficiently
• Simple setup: Works with existing tooling without major configuration

AI-friendly: Turborepo's declarative pipeline configuration is easy for AI to understand and generate. AI can optimize task dependencies, suggest caching strategies, and help configure remote caching for maximum performance gains.
