What is Turborepo?

Turborepo is a smart build system for monorepo projects. It significantly reduces build times through caching and parallel execution. It is developed by Vercel.

With AI-optimized pipelines and dependency graph analysis, it only rebuilds packages that have changed.

Core Concepts

In Turborepo, workspaces, pipeline, and cache are the core concepts. You define the build, test, and lint order of your packages with pipeline definitions.

Each pipeline task is cached based on the hash of its inputs and outputs and can be reused.

Caching Strategies

Turborepo's most powerful feature is its remote caching system. By storing build outputs in the cloud, you can use cached results even in CI environments. This reduces your team's build times from minutes to seconds.

Configuration

Turborepo is configured with a turbo.json file. This file contains pipeline definitions, cache settings, and dependency relationships. The outputs and dependsOn fields are critical configuration options.

Monorepo Best Practices

For a successful monorepo, logically separate your packages, establish clear dependency rules, and encourage code sharing. Turborepo automates these processes and increases team productivity.
