turbo

Turborepo is a high-performance build system for JavaScript and TypeScript monorepos that provides intelligent caching, parallel execution, and incremental builds. Turbo analyzes the dependency graph between packages in your monorepo and runs tasks (build, test, lint) in the optimal order with maximum parallelism, skipping work that has already been done through content-aware hashing of inputs. Local caching stores previous build outputs keyed by the hash of source files, dependencies, and environment variables, allowing subsequent builds to be completed in milliseconds by restoring cached artifacts. Remote caching through Vercel enables sharing build caches across team members and CI environments, so a build completed by one developer benefits the entire team. Turbo's pipeline configuration defines task dependencies (e.g., build depends on ^build of dependencies) and which outputs to cache. The tool integrates with any package manager (npm, yarn, pnpm) and works alongside existing build tools — it orchestrates when tasks run, not how they run. Turborepo is particularly impactful in large monorepos where full rebuilds take minutes but incremental cached builds complete in seconds.
