Turborepo

Turborepo is a high-performance build system designed for JavaScript and TypeScript monorepos, using intelligent caching and task orchestration to make builds and other tasks dramatically faster. Monorepos — single repositories containing multiple packages or apps — bring real benefits for code sharing and coordination, but they can suffer from slow builds and tests as they grow. Turborepo addresses this by caching the results of tasks and only re-running work that's actually needed, which can turn long build times into near-instant ones for unchanged code.

The tool's core innovations are its smart caching and task scheduling. Turborepo remembers the outputs of tasks (like builds, tests and linting) and skips redoing work whose inputs haven't changed, even across different machines and CI runs when remote caching is enabled. It also understands the dependencies between packages and parallelizes tasks efficiently, running them in the right order and at maximum concurrency. The result is significantly faster builds and pipelines, which improves developer productivity and reduces CI costs and waiting — a meaningful win for teams working in large monorepos.

Turborepo, now part of the Vercel ecosystem, is used by development teams that manage JavaScript/TypeScript monorepos and want to keep their builds and tasks fast as their codebase scales. By eliminating redundant work through caching and orchestrating tasks intelligently, it helps teams maintain speed and a good developer experience even in large, complex repositories. Its adoption has grown alongside the popularity of monorepos in the JavaScript ecosystem. As more teams adopt monorepos for their advantages and seek to avoid the slowdowns that can come with them, high-performance build systems are increasingly important. For development teams working in JavaScript or TypeScript monorepos that want faster builds and tasks through smart caching and orchestration, Turborepo offers a powerful, modern and widely-adopted solution.
