Made with love and Ruby on Rails. Call Nx command to get the list of affected projects for each specific task. We usually want to run just the unit tests of the packages that have been modified, and also the unit tests of the packages that are dependent on them, and the affected integration or E2E tests. In our case, the unit tests of the sum-two package should be enough, because unit tests are not mocking the dependency with sum-one. We will name it sum-one. As you can see. Note: The examples of this post are available at this Github repository. Built on Forem the open source software that powers DEV and other inclusive communities. You can examine packages by using the pnpm view command, same as npm. But there is still something important to do: We should automatically publish the modified packages whenever a release is created. Once unpublished, this post will become invisible to the public and only accessible to Javier Brea. Most upvoted and relevant comments will be first. ecmascript-6 172 Questions Once unpublished, all posts by javierbrea will become hidden and only accessible to themselves. So did I. In this post, you will see how npm Workspaces work, how to get started, and a comparison with other Workspace implementations. jquery 1233 Questions The scripts of each project can be executed independently from each package folder, and we can also define scripts for the workspace. Note also that you must configure your own NPM_TOKEN Github action secret in the repository settings. Turns out there already was an issue related to that. node.js 1112 Questions next.js 107 Questions Here we are going to use npm to install it: Now we can fill the package.json file with some basic info, and we can use Pnpm to install the dependencies. The one in the root folder should contain shared devDependencies across many projects, such as test, build or lint libraries, etc. 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. Both pnpm (as of v2.17) and Yarn (as of v1.12) support fast, concurrent installations in monorepos. So, as we dont know which packages are going to be published, we will build all of them: Then, we can add the build and publish steps to the publish job: The --no-git-checks option is used because otherwise the publish command may produce errors when executed on Github actions due to the checkout method. https://leveluptutorials.com/tutorials/monorepos-with-pnpm. For further actions, you may consider blocking this person and/or reporting abuse. We will use it to get the list of projects in which each specific task should be executed. Requirements for a good workflow, Building a Node.js monorepo using Pnpm and Nx, CI/CD for Pnpm and Nx monorepo using Github actions. Remember that we are creating jobs only for the affected projects. **/test/**' packageshttp,utils,web,server But note that the code of the projects here is not really relevant. To demonstrate with the basic example, we'll create a subpackage called A and create a dependency to it from the root package. Check the Require status checks to pass before merging option and add a new status check for the build-finished job: Now, every time a pull request is created it will require the build-finished job to be finished before allowing to merge it. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise I've also provided a repository on GitHub with some sample code from the examples. tip Create a packages/sum-one/index.spec.js containing: And then add the script for running the test: Now, you can run the package unit tests script from the package folder: But we don't want to be moving from one folder to another to run our development scripts, right? It will contain its own package.json file, and an index.js file exporting a method which sums one to a given number: For the moment, the packages/sum-one/package.json file only has to contain the basic package information: And the packages/sum-one/index.js file exports a very simple method. We will install Jest in the workspace (as mentioned above, it is a devDependency, so we don't have to install it on every single package): The -wD in the example means "Install it in the workspace, as a devDependency". That sure sounds relevant, so let's give it a try! We did a little Q&A with Scott, the author. string 110 Questions Advertisement Answer It is called "filtering" in pnpm docs ( see it here ). In this blog post, we'll explore how to set up a simple monorepo for two npm packages. Let's say I want to install a package in a specific package in my monorepo, how do I do this from root? echo "::set-output name=test-unit::$(node scripts/print-affected-array.js test:unit --all)" Afterwards we will expose some of the Nx commands that we need for our development workflow using our own package.json scripts. vuejs2 183 Questions. It's a tool that I utilize every single day in my code base and have nothing but great things to say about it. Modify the next line in the workflow, adding all currently active Node.js versions: As we can see in the next screenshot, now eight jobs are created, one for each different combination of project and Node.js version: Now we can add another jobs matrix for running the E2E tests. Let's create our first project in the packages folder. In a CI environment, installation fails if a lockfile is present but needs an update. Use pnpm without symlinks. A: pnpm (performant npm) is an alternative to npm for managing JavaScript packages. pnpm install is used to install all dependencies for a project. No packages published . Create a pnpm-workspace.yaml file in the root folder containing: You can read Pnpm workspace docs for further info about how to include/exclude subfolders. Now we can use the jest executable in the packages/sum-one/package.json file, so let's create one basic test in that package. Setup mono repo support with pnpm To support a mono repo we need to setup a workspace in PNPM so it can discover all the package.json files for apps and libs in NX. This will be the root package.json for our PNPM monorepo. Start by creating a new directory, and running npm init. All commands run through root; Use in host, hook up my monorepo to render run commands; Filter and recursive "install:all": "pnpm recursive install", Packages 0. The repository will contain also a package.json file in the root folder. Go ahead and run $ pnpm add -D typescript @types/node Next, create a new file called pnpm-workspace.yaml. 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. nx supports passing a npm script name as first argument and the package name as second argument: pnpm nx [script] [project]. Not exclusive to pnpm; Yarn, npm, pnpm all have them now. There are many methods for installing it, you can check them all in the Pnpm installation docs. mongodb 125 Questions For example, suppose that the sum-two package has a build script that must be executed before running the unit tests. 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. pnpm has a "workspaces" facility that we can use to create dependencies between packages in our monorepo. We currently have first-class support for yarn workspaces. Terms of Use With you every step of your journey. most cases, pnpm is still a choice, it has so called "workspaces" concept and you can specify each of your projects as a pnpm workspace. So, I have omitted that extra configuration in order to keep the examples of this post as simple as possible. packages components website. As a quick recap, in the previous post we finished with a monorepo containing two Node.js packages and one E2E testing project. We will use the sum-two and sum-one packages to execute the test, so we define the dependencies, and note that we have also added a script named test:e2e. About the pnpm JavaScript package manager. Thats why we are going to use Github matrixes and jobs to distribute the tasks. Note the usage of workspace:* for creating a local reference from one package to another, that will be replaced by the real version of the other package (1.0.0-alpha.1) when this one is published. As we are already creating our unit testing jobs from a dynamic matrix, so now it is easy to add more Node.js versions to it. From now, every time a formal release is declared in Github, the workflow will be triggered: And the packages will be built and published automatically: In this post we have seen how to build a continuous integration workflow for a Pnpm and Nx monorepo using Github actions. It is very similar to the one running the unit tests, but now we are going to execute it using only the two latest Node.js versions: At this point, the workflow is almost ready. Lets say I want to install a package in a specific package in my monorepo, how do I do this from root? It provides lots of options for filtering projects, enabling/disabling parallel executions, etc. regex 176 Questions But the problem is that we dont know which status checks will be executed on each different pull request, because not every job will be executed always. 1 I wanted to bring awareness that this stuff is really accessible. Posted on Apr 26 In the previous chapter of this series of posts, we analyzed the reasons for using a monorepo to maintain many Node.js dependent packages, and the requirements to have a good development and continuous integration workflow. Sep 12, 2022 Author KAITLIN BLOOM This month we released a fresh course covering Monorepos with pnpm made by Scott Tolinski! This is useful to differentiate the type of test that we want to execute, so we can run affected E2E tests and unit tests in a different stage of the pipeline, for example. (As we will see later, in reality, this script shouldn't be used very usual, because we should run only the unit tests of the affected packages, but it is added only to illustrate how to add custom scripts for making our workflow easier). Upon completing this course, youll feel that you have the ability/control to do everything you already do in npm daily in pnpm with confidence and ease. Different syntax ```jsx packages: "packages/**" 12:48 - How it works in practice. But remember that we defined as a requirement that the tests should be executed on different platforms also. echo "::set-output name=test-e2e::$(node scripts/print-affected-array.js test:e2e --all)" We want to create a new monorepo with the following structure. Here we are going to use npm to install it: npm install -g pnpm@next-7 PNPM is a Fast, disk space efficient package manager. fi, # Export the branch names as output to be able to use it in other jobs, # Configure Nx to be able to detect changes between branches when we are in a PR, # When not in a PR and the current branch is main, pass --all flag. code of conduct because it is harassing, offensive or spammy. For example, let's add one script for running all unit tests of all packages in the workspace. In this course he'll mentor us through building confidence with monorepo workflows and new tools, and build faster and more efficient workflows. Once unsuspended, javierbrea will be able to comment and publish posts again. 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. The goal of using pnpm is to s ave disk space and boost installation speed When using npm or Yarn, if you have 100 projects using a dependency, you will have 100 copies of that dependency saved on disk. So, let's add one unit test to our recently created package in order to see an example. Both packages have unit tests and they share the jest dependency, but we can run them only from each different package folder. For example, we can run the unit tests of sum-one: Note that we use pnpm nx to run any nx command through our workspace nx installed dependency instead of having it installed globally. As we can see in the schema, there are two different pipelines that we should create for our workflow. 1 watching Forks. It can help speed up development for larger projects, makes it easier to share code, and act as a single source of truth. Short story: you can use Nx easily together with your current Lerna/Yarn/PNPM/NPM monorepo setup. Like Yarn, pnpm creates a node_modules in the root of the repo. . 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. Simply run: This will open automatically a browser tab with the Nx dependencies graph: In a previous step, we added a script to run all unit tests of all packages in the workspace just to show how to add useful alias scripts to our workspace. # pnpm-workspace.yaml packages: - "admin" - "client" - "shared" Use of this site constitutes acceptance of our The example is valid if you are going to publish to the NPM registry, otherwise, you should also set up your own registry url in the Pnpm configuration before publishing. The default base branch to compare with is defined in the nx.json file that we created previously, which in this case is main. So, supposing that you have a repository and you have all previous changes promoted to the main branch, if you modify the packages/sum-two/index.js file, running the next command would execute only the unit tests of the sum-two package, because no other package depends on it. If you are preparing your next release and you decided to use a new dependency but forgot to declare it in the package.json file, your tests might still pass locally if another package already downloaded that dependency into the workspace root. The name of the folders is something that can be changed at your convenience. Monorepo example with pnpm. So foo is able to resolve only is-positive and bar is only able to resolve is-negative . Unflagging javierbrea will restore default visibility to their posts. My use case for a monorepo: static site generation You could store your packages depending of their type in different folders, for example. Now we can run the unit tests of the affected packages with a single command, but, what about if the unit:test script in any package needs any other script to be executed before? Monorepos, or "monolithic repositories", are single repositories containing multiple apps or packages. Head of front-end development at Telefnica Tech, Designing and developing software since 2002. About. With pnpm, the dependency will be stored in a content-addressable store, so: NOTE: If you are using a Pnpm version lower than 7.0, you should add an extra -- to the Pnpm commands before the Nx arguments: pnpm nx affected -- --target=test:unit. echo "::set-output name=branch::main" forms 107 Questions vue.js 610 Questions I have omitted them in order to keep the examples as simple as possible, but lets see some of them. Templates let you quickly answer FAQs or store snippets for re-use. If you used local npmrc in your Lerna repo, copy it to the use-lerna-repo root folder. 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. In the next chapter, we will use this example to create a continuous integration workflow for the monorepo using a Github action. mkdir monorepo-nextjs cd monorepo-nextjs npm init It will ignore the skipped matrixes, because sometimes no unit-test matrix will be created, or no test-e2e will be executed, etc. Install as devDependencies the required nx packages and typescript, which is a peer dependency: Nx has a lot of configuration options, but for the moment we are going to see only the basic configuration that allows to execute any package script from the root workspace folder, see the dependencies graph, etc. Inside a workspace, pnpm install installs all dependencies in all the projects. Its amazing! For simplicity of the examples, here we will show only the scripts property of the package.json file: Now we can use nx to run any script of any project in the workspace from the root folder. pnpm run build pnpm run start. 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 . Go to the Settings tab of the repository. Why a Pnpm and Nx monorepo? 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. Here, we will configure all the different projects that we'll have. but note that the dependencies of each package (those required to work once they are published) must remain on their own package.json files. You can learn more about the nx interface in its API reference page. This can be achieved using a bash script in the workflow itself, or using any other type of script at your convenience, so for brevity I will omit the code in this post. echo "::set-output name=test-e2e::$(node scripts/print-affected-array.js test:e2e origin/${{needs.branch-info.outputs.base-branch-name}})" This is the job that we are going to use to require the status check in order to let all of the other jobs finishing before allowing to merge the pull request. Empty NX monorepo. For that, we will use the Pnpm Workspace feature, that allows to reference workspace packages through aliases. in npm, you can do this with something like this: 2 1 npm install react --workspace=a 2 I searched the docs and I can't find a way to do this in pnpm. This is something that we wouldnt need when talking about front-end projects, for example. 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. # Get base branch name to compare with. Otherwise, they will be missing when the packages are published. Q: What is pnpm? However, there is a big difference between how they store dependencies in monorepos. NX aims to provide a holistic dev experience via CLI (with editor plugins), and capabilities for controlled code sharing, and consistent code generation. Adding more tasks, such as linting the code, running integration test, etc., could be also added easily, but we will create only these ones for keeping the examples as simple as possible.
