To fully complete this tutorial, you will need to have Yarn installed on your machine. To follow along, you’ll need a working environment with an up-to-date npm install. Now let’s learn from scratch how to set up a new project using Yarn workspaces. So far, we have learned what Yarn is, what a monorepo is, and why Yarn is a great tool to create a monorepo. Creating A Monorepo Project With React And Express Using Yarn Workspaces In Six Steps In the next section we will learn how to create our first monorepo project with Yarn. Also, React uses Yarn workspaces to achieve that purpose. React is a good example of an open-source project that is monorepo. We’ll run through a tutorial together on how to create your first project with it, and we’ll finish with a recap and next steps. In this article, I share an intro to Yarn workspaces. Shared utilities and code without versioning.Īfter some research, I found that Yarn workspaces was a great tool to solve those cons, and it was a helpful tool to create a monorepo project (more to come later!).Since I rely on a global package.json, I didn’t have a mechanism to set specific versions for the back end and front end. However, I found some downsides:īoth apps were using the same package.json, and there was no clear separation on both projects. I adopted this organization for convenience, since having both projects in the same repo made it easy to search for functions and classes, and facilitated refactors. I originally had all the code in the same repository: the back end used Node.js and the front end used ES6 with Pug. I had this same question after a few months working on my personal website. In this article, Jorge explains why they’re a great tool and how to create your first monorepo using Yarn with basic npm scripts, and add the required dependencies for each app.Īny time I start working on a new project, I ask myself, “Should I use separate git repositories for my back-end server and my front-end client(s)? What’s the best way to organize the codebase?” React makes use of the yarn workspace mechanism.Yarn workspaces let you organize your project codebase using a monolithic repository (monorepo). The packages are independent of each other, and can be a complete standalone project even if they are separated from the main repository. Yarn workspace allows a single git repository to contain multiple packages for example, if you have a front-end project and a back-end project, you can manage both packages through yarn workspace. Today, I’m documenting a way I often manage my code - yarn workspace. I’ve often struggled with this before and have looked up a lot of information about it. So wouldn’t this be a straightforward way to manage the project with a different git repository? It’s true, but if different projects are in different git repositories, it’s not particularly convenient when I have to look up some code in another project, so I’d like to have all the relevant packages in one git repository. Whenever you are ready to write a new project, have you ever thought about whether you need to manage the front and back-end code with different git repositories, or whether you need to split some relatively low-level code into a separate git repository, so that when the low-level code is stable, you can directly release it as a separate npm package for the project. ![]()
