Then we saw how to build a Pnpm and Nx monorepo. nx supports passing a npm script name as first argument and the package name as second argument: pnpm nx [script] [project]. Here, we will configure all the different projects that we'll have. https://leveluptutorials.com/tutorials/monorepos-with-pnpm. DEV Community A constructive and inclusive social network for software developers. The docs are at https://pnpm.io . We want to create a new monorepo with the following structure. Now that we have installed Pnpm, we have to configure it so it can know which is the root of the workspace, and where are the packages. echo "::set-output name=test-unit::$(node scripts/print-affected-array.js test:unit --all)" 3. Now we are going to see how to create a continous integration workflow for the Nx and Pnpm monorepo using Github actions. pnpm install is used to install all dependencies for a project. The repository will contain also a package.json file in the root folder. (needs.test-e2e-windows.result == 'success' || needs.test-e2e-windows.result == 'skipped'), # Publish all packages in the workspace which version still does not exist, command for listing the affected projects, Why a monorepo? With you every step of your journey. Not exclusive to pnpm; Yarn, npm, pnpm all have them now. I have omitted them in order to keep the examples as simple as possible, but lets see some of them. As a tip, you can add your own branch name to the list of branches in the workflow for testing it without opening a PR. Note that, depending whether the workflow is triggered by a pull request or not, we will get the information using different Github actions variables. To demonstrate with the basic example, we'll create a subpackage called A and create a dependency to it from the root package. At that moment, a PR would be opened to main, and once it passed the checks and it is merged, a new release would be created by tagging the main branch. ; both packages are inside a folder called node_modules; foo can require bar, because Node.js looks modules up in the directory structure till the root of the disk.And foo can also require foo, because it is in a folder called node_modules (yep, this is what some packages do). Front-end specialist. (needs.test-e2e.result == 'success' || needs.test-e2e.result == 'skipped') && We will name sum-two to our new package, and it will depend on sum-one: Here is the content of the packages/sum-two/package.json file. Modify the targetDependencies property in the nx.json file as in: Now, we are ready to install the dependencies of the new project, reset the nx cache (this is recommended when adding a new project) and run the E2E tests: We can also run the Nx graph command to see how our dependencies graph has changed after adding this new project: You may have noticed that Nx does not recognize the sum-e2e project as of e2e type. But, if you create another branch and modify the packages/sum-one/index.js file, running pnpm test:unit:affected would execute the unit tests of both packages, because modifying sum-one also affects to sum-two. It is calculating the affected projects and it is creating two matrixes of jobs for the affected projects, one for the unit testing and another one for E2E testing. Lets see how Yarn and pnpm work on a simple example: To make this repo work with Yarn, there should be a package.json in the root of the repo with the following content: To install all dependencies of all workspace packages, you should run yarn install. For doing that, we are going to use the Github repository settings. In this post we have seen how to create a monorepo using Pnpm and Nx. Lets make a list with all of the requirements: Note that some of these are specific requirements for projects containing Node.js packages, such as the multi version testing. They can still re-publish the post if they are not suspended. Now we are going to install Nx because it provides the other requirements that we saw in the previous post: Nx can also be installed globally, but I prefer to install it as a project dependency in order to define a specific version, so the same version is always used in all different local and remote environments. Node's resolution algorithm will not find them. Negative or Positive Number to 32 Bit Binary Data in JS. As you can see, pnpm is strict not only when used with a single package.json but also in a multi-package repository. The default base branch to compare with is defined in the nx.json file that we created previously, which in this case is main. I have created a scripts/print-affected-array.js script in the sample repository that gets the needed output, and thats what we are going to call from the pipeline, passing two arguments to it: the task to be executed and the base branch. Even when Nx is able to run tasks in parallel, all of them would be executed in the same step, so it could end in performance issues depending on the heavy that our tasks are. NX is an advanced set of extensible dev tools for monorepos, with a strong emphasis on modern full-stack web technologies. For that, we will use the Pnpm Workspace feature, that allows to reference workspace packages through aliases. Start by creating a new directory, and running npm init. About the pnpm JavaScript package manager. pnpm + changesets works pretty well. echo "::set-output name=test-e2e::$(node scripts/print-affected-array.js test:e2e --all)" **/test/**' packageshttp,utils,web,server Go ahead and run $ pnpm add -D typescript @types/node Next, create a new file called pnpm-workspace.yaml. string 110 Questions This article is focused on Node.js packages, but most of the contents could be valid also for other type of projects with minimal changes. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise next.js 107 Questions Its amazing! Open up the file and add the following lines to it. Creating the monorepo. mongodb 125 Questions A monorepo is a single repository that is used to manage multiple projects. Base branch on a PR, "main" branch on pushing. else So did I. All we need is already built into npm and TypeScript. This is a step-by-step guide, but you can directly check the repository code while reading for a faster approach. code of conduct because it is harassing, offensive or spammy. pnpm run build pnpm run start. Likewise, there is a symlink to is-positive in the node_modules directory of foo. So, I have omitted that extra configuration in order to keep the examples of this post as simple as possible. (needs.test-unit.result == 'success' || needs.test-unit.result == 'skipped') && This guide will set up a simple monorepo with an Expo project. Let's create our first project in the packages folder. A: Together well take it one step at a time, understand why we need the tools, what they are, and then understand how to create the base project so were able to orchestrate things in our day to day. Turborepo is a high-performance build system for JavaScript and TypeScript codebases. This way we can configure the number of max parallel tasks to be executed also in the workflow configuration, and, depending on the number of projects, and the heavy the tasks are, we can adjust the parameters to get the workflow finished as fast as possible. We will name it sum-one. But remember that we defined as a requirement that the tests should be executed on different platforms also. First, create a project to consume the aloha-world and hello-world packages: mkdir use -lerna -repo cd use -lerna -repo / yarn init Assuming you've used global .npmrc, no further steps are needed to consume the packages with yarn or npm install. Lets add the test-unit job: Here is a screenshot showing how the test-unit matrix contains one different job for each project containing the test:unit script (supposing that both projects are affected): I have not configured in the example any tool to collect the projects unit testing coverage, this is something that I will explain in another post. Related docs: https://pnpm.io/npmrc#node-linker Share Improve this answer Follow answered Oct 7 at 21:15 Zoltan Kochan 3,497 21 33 A: We'll cover foundational knowledge of how monorepos function, and why. We will import this package and use it from the other one afterwards in order to see how we can define dependencies between projects in the monorepo workspace. an iOS client and a web-application) These projects are most likely unrelated, loosely connected or can be connected by other means (e.g via dependency management tools) The repository is large in many ways: - Number of commits - Number of branches and/or . It means that both foo and bar will have access to the dependencies of each other. Today, we are happy to announce the release of Nx 10.4 that includes the introduction of cleaner ESLint configuration, Pnpm compatibility, and more! Its branching model and pipeline stages are oriented to a repository containing NPM packages, but it can be easily adapted to any other type of projects. The configuration could be improved in order to let Nx know the type of each project for adding more features like architecture boundaries using eslint, etc., but this, among other lot of things that obviously can be improved, is out of the scope of this post. Abonnez-vous https://bit.ly/GrafikartSubscribe Dans ce tutoriel je vous propose de dcouvrir les workspace pnpm et leur utilisation dans le cadre d'une structure monorepo.

So, let's add a fake build script to the packages/sum-two/package.json file: You can check that the new script works properly by running: If the command above does not work, try cleaning the nx cache running pnpm nx reset. For further actions, you may consider blocking this person and/or reporting abuse. To create the first Github action, add a file named .github/workflows/build.yml: For the moment we will add to it the configuration defining the events that will trigger it: We will need to know which is the base branch in many steps of our workflow in order to configure Nx properly and to be able to calculate the affected projects, for example. Lerna is a high-level monorepo tool that provides abstractions to simultaneously manage a single or multiple apps/packages. function 101 Questions Its branching model and pipeline stages are oriented to a repository containing NPM packages, but it can be easily adapted to any other type of projects.
