turborepo

Monorepo build optimization is achieved by configuring Turborepo to cache task outputs and filter execution using --affected or --filter flags. This ensures your CI pipeline only builds and tests packages impacted by a code change, significantly reducing build times.

Task orchestration in a monorepo works by defining task pipelines in turbo.json using the dependsOn field. This optimizes execution order based on package dependencies, ensuring build, test, and lint tasks run sequentially or in parallel as needed.

To configure a new build task in Turborepo, you define the task within turbo.json and specify its output locations using the outputs field. The build system then caches these outputs automatically, skipping re-execution if inputs remain unchanged.

Remote caching can be used to speed up CI pipelines by sharing cached task outputs across different environments. Turborepo manages this remote caching alongside local caching to avoid redundant task execution and optimize continuous integration workflows.

The turbo.json file serves as the central configuration for a Turborepo monorepo build system. It defines task pipelines, manages dependency chains via dependsOn, configures output caching via outputs, and sets up task execution rules.
