Turborepo is a high-performance build system optimized for JavaScript and TypeScript codebases that dramatically speeds up development and continuous integration by optimizing workflows with parallel task execution, intelligent scheduling, incremental builds, and remote caching so you never do the same work twice. It works with any package manager (npm, yarn, pnpm) and integrates with any CI provider, letting you start a new repository or incrementally migrate an existing one with minimal setup using a single turbo.json configuration that builds on your existing package.json scripts. Turborepo understands the relationships between tasks and packages, runs only affected tasks, and can share cached results across machines and team members, reducing build times significantly. Its core concepts include remote caching, efficient task and package graphs, and support for multiple package types in a monorepo, while guides show how to integrate with favorite frameworks and tooling.
