Monorepos have gained popularity for managing complex projects by consolidating all related components into a single repository, offering better visibility, shared code, and synchronized releases. Turborepo is a tool designed for enhancing the performance of JavaScript and TypeScript monorepos through fast builds, remote caching, and flexible task configurations, integrating well with existing package managers like npm and Yarn. It improves build times significantly by using techniques such as content-based hashing and task multitasking, though it lacks integration with certain frameworks and tools and is limited to JavaScript and TypeScript, which may restrict its use in more diverse projects. Despite these limitations, Turborepo provides substantial performance improvements for monorepos, allowing developers to define and execute tasks efficiently. The article also offers a practical guide on setting up a monorepo with Turborepo, demonstrating the process with a hypothetical blogging service, and explores the benefits of using Earthly alongside Turborepo for enhanced build performance.
