### [Building a Monorepo with Yarn 2](https://yomu.fyi/post/building-a-monorepo-with-yarn-2.md)

The post presents Yarn 2 workspaces as a way to manage dependencies for a JavaScript or Node.js monorepo containing separate server and UI applications. It configures the root package.json with workspace directories, imports the workspace-tools plugin, pins the project to a checked-in Yarn binary with yarn set version berry, and enables the dependency cache through .yarn/cache and Plug’n’Play. The walkthrough adds Express, TypeScript, and @types/express to a server workspace, creates a Next.js UI workspace, and uses workspace scripts to build both applications, while yarn dlx initializes TypeScript without a global install. It also shows the Git files to retain, generated JavaScript to ignore, and a Heroku start script that launches the server workspace; the stated benefit is faster installs through a committed cache and zero-install deployment.
