turborepo

Monorepo task pipelines execute in the correct dependency order by defining task graphs in turbo.json. This orchestrates cross-package builds using dependsOn syntax, ensuring upstream packages finish before downstream tasks start. You define per-package configurations to manage this sequence.

Speed up CI builds in a large monorepo by applying incremental builds and efficient caching strategies. Using --affected filtering and parallel task execution limits work to changed packages, while remote cache patterns avoid redundant processing across continuous integration runs.

Caching for monorepo build tasks works by matching declared inputs and environment variables to stored outputs. When inputs remain unchanged, the pipeline restores cached outputs directly instead of re-executing the build, significantly reducing local and CI computation time.

Yes, you can define per-package task configurations separately from the root monorepo configuration. This enforces root vs package configuration boundaries, allowing individual apps and packages to declare their own inputs, outputs, and env handling within the task graph.

You need dependsOn syntax in a monorepo build pipeline when a specific task requires another task in a different package to finish first. It enforces correct dependency order within the task graph, preventing downstream execution before upstream builds and tasks complete.
