📦 Monorepo Architecture with pnpm Workspace, Turborepo & Changesets

When you're developing a project with multiple packages, managing each one in its own repo can quickly turn into a nightmare. In this article, we'll set up a monorepo architecture from scratch using pnpm workspace, speed up build processes with Turborepo, and build an automated NPM publish pipeline with Changesets. 🏗️ What Is a Monorepo? Let's say you're building a design system. You have a core package, a theme package, and a utils package. Now imagine keeping all of these in separate repositories. When you fix a bug in the core package, what happens? You switch to the theme repo and update the dependency. Then you switch to the utils repo. You open separate PRs for each, wait for separate CI/CD pipelines, and publish separately. Even with just three packages, this process is exhausting — with ten, it's a total nightmare. This is exactly where the monorepo comes in. A monorepo is an architectural approach that houses multiple projects under a single repository. All your packages live
