Using a monorepo every project in the monorepo can share the same set of dependencies, making sure every project is on the same page. So, basically it should work in most cases. However, in some cases, Just like the scripts above, adding dependency to a workspace is: $ yarn workspace shared add -D typescript $ yarn workspace backend add -D typescript Run yarn install again in root project, yarn will hoist the same dependencies among sub projects to the top level node_modules. In this article, we explore the principles behind Yarn workspaces and learn how to use them. . They allow you to run yarn install to manage and install dependencies across multiple 3. Yarn Workspaces allow for even more efficient hoisting of shared dependencies, improving install times and reducing node_modules size. However, I've not stopped searching for the answer and can share my opinion. json (contains shared dependencies, eg. Is it possible to share config variables / env variables across subfolders of a monorepo that is set up using yarn workspaces? We've got a monorepo for a project, and several of the subfolders are projects that are built using create-react-app. They allow you to run yarn install to manage and install dependencies across multiple Your dependencies can be linked together, which means that your workspaces can depend on one another while always using the most up-to-date code available.

Given the fact that yarn workspaces will share the dependencies if their versions are the same (see https://classic. Allowing Workspaces to hoist shared dependencies to the root means shared dependencies will only exist in the root so we would have to pull them back into each service during bundling or deployment. NPM Workspaces monorepo - share local package's distribution folder as root instead of the entire source files. Let’s say you have React. We can use Yarn workspaces designed with monorepos in mind to handle all that. The setup is as follows: package. Making assumptions about this layout was already I have a yarn workspaces project which looks something like this: If the server has a dependency on the shared lib, you could publish it to npm so it can fetch it too. com/lang/en/docs/workspaces/), all we have to do is to keep the dependency versions in sync to make dependencies sharing, which is exactly what Recently, I wrote and article about setting up yarn workspaces and adding Docker support to it for orchestration. 22) on a monorepo with both an Angular app and library.

A share tsconfig It is using yarn(v1) workspaces. I thought we can extend this setup to include a library as well. By adopting a monorepo pattern, we could share those third-party dependencies among the three projects from just a single source (one node_modules directory). In general, if you run script in the root directory, it should pick its dependencies from the root node_modules only. Yarn Workspaces is used to optimize and link different packages together. json "dependencies": { "external-lib-dep": "^1. Here is what I'll do to add React on both workspaces: yarn workspace admin-app add react yarn workspace user-app add react Currently, this results in both of my packages depending on "react": "^17.

This command takes a list of workspaces, extend the list to include transitive dependencies, and exclude everything else from the install. json". This is also a better mechanism than yarn link since it only affects By adopting a monorepo pattern, we could share those third-party dependencies among the three projects from just a single source (one node_modules directory). So for example I didn't have to have @babel/plugin-syntax-dynamic-import inside packages/my-app , it worked. For example, the following would let you install This article provides a comprehensive guide on setting up a monorepo using Yarn Workspaces, featuring a NextJs frontend, NodeJs backend, and a shared common project. In short, they allow multiple projects to live together in the same repository AND to cross-reference each other - any modification to one's source code being instantly applied to the others. Strict workspace topology (optional) I suggest to be strict about what packages depends on (to have clear boundaries). The package layout will be different between your workspace and what your users will get (the workspace dependencies will be hoisted higher into the filesystem hierarchy). Yarn workspaces let you organize your project codebase using a monolithic repository (monorepo). json files in subfolders of a single root package. Say goodbye to node_modules. 4. To enable Yarn Workspaces in Lerna, add the following to your lerna. However, he found some downsides. In this article, Jorge explains why they’re a great tool and how to create For those use cases, Yarn now supports a new resolution protocol starting from the v2: workspace:. One of the packages contains a set of development dependencies ( packages/example-dev / @example/dev ) that are consumed as a package by applications external to the monorepo. You can also specify the name of the workspace as an argument, e. Both NPM and Yarn Workspaces automatically hoist shared dependencies to the root node_modules folder to avoid duplicating them across packages. I try to keep things pretty high level but I have tried to create a separate package for esLint config and consume it in project-packages(by installing it and extending it), however I ran into two issues: I then do yarn workspace frontend add shared and yarn workspace server add shared and successfully find that the shared package is listed as a workspace dependency for server and frontend in yarn list. While working on his personal website, Jorge Ferreiro had all the code in the same repository: the back end used Node.

Bonus info I created a Github Repository to make it easier to follow the following code description:. json was my-config package, and it would resolve all it's dependencies correctly. js Project, Yarn I want to set up a project with a client part (react-app), a server part (express) and a shared library (utils) in typescript. Seemed like an easy way to ensure the same version of those tools was used across all three workspaces. To go over our setup, we h With Yarn 1, I put the "typescript", "eslint", and "jest" dependencies in the top-level "package. Sharing typescript code between two projects in a monorepo with yarn 2 workspaces. (Source: Project References Documentation) TypeScript Setup. David Callanan. TypeScript Project References make it possible to compile a TypeScript project that consist of multiple smaller TypeScript projects, each project having a tsconfig. This is the default behaviour unless you specify the "legacy" node-modules linker Documented here. When this protocol is used Yarn will refuse to resolve to anything else than a local workspace. js & React Native Application and both using Redux, instead of installing Redux into React Native Project and React. Share. Improve this answer. Dependency Resolution: Yarn classic workspaces use a “pluggable” resolution algorithm, providing more flexibility in how dependencies are resolved. These packages tend to depend on Automatic Dependency Hoisting: NPM Workspaces automatically hoists shared dependencies to the root node_modules folder, making dependency management more efficient. That is what you described in option 2. Workspaces are a new way to set up your package architecture that’s available by default starting from Yarn 1.
