 In this article we're going to have a deep dive into setting up a new monorepo using [PNPM workspaces](https://pnpm.io/workspaces) that hosts a Remix application as well as a React-based library. We will learn how to run commands with PNPM, how to run them in parallel and finally we're going to add Nx for a more sophisticated task scheduling, including command caching and more.
