Why teams consolidate into a single repository

Monorepos keep multiple projects — often spanning different frameworks — in one unified codebase. Large organizations have relied on this structure for years, and modern tooling has made it practical for smaller teams as well. Consolidating repositories brings four main benefits: easier cross-package updates, simpler collaboration and debugging, smoother local development, and faster builds through shared caching.

Updating shared code without the version treadmill

Consider a component library distributed as an npm package and consumed by 100 separate repositories. Every release means publishing a new version and then updating each consumer independently. Repositories drift apart, and inconsistencies creep in — the button looks different on one page because it's running a different version of the library.

In a monorepo, a package version update happens in one place and propagates to every dependent project. You avoid coordinating commits across multiple repositories, and consistency across products is enforced by the structure itself.

Collaboration and debugging in one place

When critical system components are spread across many repositories, finding the code you need can be a hunt. A single repository makes it easier to search, share, and reuse code across applications and libraries — and to enforce organizational standards in a centralized location.

Working on shared components or services across separately published repositories typically relies on npm link. That approach does not scale; symlinking dozens of repositories together to run a local end-to-end test is impractical.

Monorepos let teams set up testing, linting, formatting, publishing, and other tasks once, in one place, where dependencies can be managed and upgraded together. This setup keeps toolchains for less-active applications from falling behind, making them easy to run when you revisit the codebase later.

Turborepo’s approach

Turborepo is a high-performance build system for JavaScript and TypeScript codebases, designed around the workflows used by large-scale engineering organizations. It abstracts the complex configuration normally required for monorepos and provides fast, incremental builds with zero-configuration remote caching.

Instead of spending time worrying about how you're shipping, Turborepo handles configuration, scripts, and tooling so you can focus on what you're shipping. Each workspace can have its own build, test, and typecheck scripts while Turborepo manages when they execute and caches the results.

Remote caching and shared build state

Turborepo caches the output of any previously executed command — tests, builds, and more — so it can replay results instead of rerunning them. By default, that cache lives on the machine that ran the command.

With remote caching, the cache is shared across your entire team and CI pipeline. Unchanged code is not re-compiled, re-tested, or re-executed, which cuts build times dramatically. Teams using Turborepo with remote caching on Vercel have reported saving hundreds of days of CI time.

"Turborepo has saved us 67 hours of CI since we adopted it. That's for a team of only four full-time developers."

Getting started involves adopting Turborepo and enabling remote caching to see immediate gains in workflow speed and developer experience.
