turborepo

Monorepo build pipelines orchestrate tasks across multiple packages with caching to avoid redundant work. Configure turbo.json to define task dependencies, outputs, and inputs, then run filtered tasks like `turbo run build --filter=./apps/web` to execute only affected packages and leverage cached results.

Proper outputs and inputs configuration enables Turborepo's caching mechanism. Define outputs as build artifacts (dist, build folders) and inputs as source files that trigger cache invalidation. This ensures tasks run only when dependencies change, speeding up CI and local workflows.

Remote caching extends Turborepo's caching across machines and CI runs. Configure remote caching in turbo.json to store and retrieve task outputs from a central location, allowing teams to reuse builds across pipelines, reducing CI time and bandwidth.

CI optimization uses filtering and dependency graphs to run only affected tasks. Turborepo analyzes package dependencies and task graphs to execute targeted builds for changed workspaces, reducing unnecessary work and accelerating feedback loops in continuous integration.

Per-package tasks are essential for monorepo scalability and caching effectiveness. Each package defines its own tasks in package.json, allowing Turborepo to understand dependencies, parallelize execution, and cache results independently, rather than running root-wide commands that bypass optimization.

Turborepo's dependency graph awareness ensures tasks execute in the correct order. Define task dependencies in turbo.json using the `dependsOn` field to specify which tasks must complete before others run, enabling efficient parallelization while respecting package relationships.
