![]() Navigate to the newly created project directory root and create your package.json.ģ. Create your main project directory with a command like this:Ģ. Setting up a Yarn Workspace is as easy as running a few commands and making some edits to a few simple pages. How Do You Set Up A Yarn Workspace? And What Does It Looks Like? Let’s now take a look at what it actually looks like and how we can go about setting it up within a project. So now that we have a clearer overall picture of what a Yarn Workspace is in general. – Yarn gets to make a single lock file rather than multiple, giving you fewer conflicts and making code review easier. – All your dependencies installed together at one time, leading to better ability for Yarn to optimize them. Leading to more up to date code in general. ![]() – Better code-quality and optimization due to packages being linked together. Whose benefits alongside the obvious bloat reduction mentioned above, include: One of the most prominent (within the NPM ecosystem) of which is the Yarn Workspace. That solution as we have stated above is the monorepo. Infact, its been around for a long time.įortunately, there are now solutions to this problem. These issues are what are commonly referred to as ‘ dependency hell’.Īnd it’s not a new issue. Not to mention the issues that would arise from dealing with out-of-date code and the potential conflicts in the overall codebase. With a separate /client and /server folder structure, each with their own package.json and subsequent package dependencies.Įach of these projects would have to be loading in their own dependencies, and sometimes, as shown in the drawing above, having the same duplicate dependencies loaded in for each folder, causing massive unnecessary bloat. Imagine now, with these large individual file sizes on each project, that we had a multi-project setup with each project that needed to have its own dependencies, such as what you might find in a standard MERN or MEVN stack. I’m sure we’re all familiar with the infamous Godzilla 500+ MB /node_modules folder. When working on more complex projects, with dependencies from a variety of frameworks, this size can swell even more. The average node js project, specifically the dependencies located within it, have a total estimated size of 76MB.įor a single, web based project for example, this is huge. While the emergence of open source packages within the NPM ecosystem has lead to tremendous benefits and time-saved on project code, the fact that so many node modules are now needed for even the simplest of projects has led to a lot of bloat in overall project size. The Multi-Megabyte Problem that a Yarn Workspace solves To get an even better understanding of what a Yarn Workspace is, it’s best to take a look at the broader picture of the problem it solves and why that problem exists in the first place. This is commonly referred to as a ‘ monorepo ’. We can briefly state that a Yarn Workspace is a method of combining multiple project NPM dependencies into a single workspace, so that all projects share the same dependencies. This is what we will first do with Yarn Workspaces before we dive into the way we can use them for our projects. This means getting the definition of what it is to be as crystal clear as possible for me, in all areas that compose the technology. Then once I start introducing the code, the autoreload partially compiles and only causes CSR to run, allowing the page to fully load since it is now only being included on the CSR step and not both steps.Before I start to use a new technology, I first try to make sure that I really understand what it is. It probably does a SSR build without the module import. This actually probably supports the post above that causes the rendering to work if I slowly introduce the code. var DineroJs = require("dinero.js").default ![]() It will crash before rendering that initial render completely. default on the require() statement in the generated bs.js file. default from the require() statement I will see the initial page render for a second or two, then when client does rendering it crashes. It almost seems like this is an issue when doing SSR vs. Why would this be different in the two different places? The webpack build process? I am completely out of ideas. This package is working in multiple places with zero issues.Īs soon as its used via the wonka package within the nextjs app it breaks. This issue is 100% caused by the nextjs template. Let me explain.įirst the File looks as so: make = (~amount: Money.t) => Īnd the nextjs app that uses this file as a dependency will not error and be displayed properly! This is beyond weird. If I slowly introduce the code (I know this is super odd) - it will work. Okay this is probably the strangest thing ever.
