Go to the Settings tab of the repository. Otherwise, they will be missing when the packages are published. There are many methods for installing it, you can check them all in the Pnpm installation docs. It means that both foo and bar will have access to the dependencies of each other. discord.js 177 Questions 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. This is a step-by-step tutorial, but if you want to have all the code available, all of the examples are in this Github repository. Note that here we are configuring Nx using the output from the previous job, so we have to declare the dependency using the needs property: Nx provides a command for listing the affected projects. echo "::set-output name=test-unit::$(node scripts/print-affected-array.js test:unit --all)" . Adding Nx is a low impact operation that does not require any particular change to your repository like how your packages and scripts are organized. I have omitted them in order to keep the examples as simple as possible, but lets see some of them. Turns out there already was an issue related to that. There are many methods for installing it, you can check them all in the Pnpm installation docs. To make pnpm install dependencies in this repo, youll need to create a pnpm-workspace.yaml in the root of the repo (it can be empty) and a .npmrc file with the following content: To install all dependencies of all workspace packages with pnpm, you should run pnpm multi install (or just pnpm m i). It is probably also handy to initialize a new Git repository such that we can commit and backup things as we progress in the setup: next.js 107 Questions 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. We currently have first-class support for yarn workspaces. Creating the monorepo. At this point, we have a workflow that is able to detect which tasks should we execute depending on the affected projects. Remember that we are creating jobs only for the affected projects. there is a small monorepo with two packages. monorepolerna,yarnpnpm,pnpmyarnpnpmmonorepo pnpm-workspace.yaml / packages : # packages/ package - 'packages/**' # test package - '! So when you have a tool like this that gets it out of the way and makes it that easy with just a little config. 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. 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. In order to have a full example before going to the next chapter, in which we will create a continuous integration pipeline using a Github action, we are going to add also a project containing E2E tests. Made with love and Ruby on Rails. Expected behavior: pnpm view eslint-config-berkekaragoz@0.1.8: Actual behavior: pnpm view eslint-config-berkekaragoz@0.1.7: I joined pnpm's Discord server: r.pnpm.io/chat. Requirements for a good workflow, Building a Node.js monorepo using Pnpm and Nx, CI/CD for Pnpm and Nx monorepo using Github actions. The two dashes ( --) after the main command allow upcoming arguments to be passed to command being executed rather than to Lerna. Here we are going to use npm to install it: npm install -g pnpm@next-7 Once unpublished, this post will become invisible to the public and only accessible to Javier Brea. It will contain some Nx basic configuration: As we have not installed Nx globally, we need to define a script in our workspace package.json file to allow running its commands. It's a tool that I utilize every single day in my code base and have nothing but great things to say about it. Then select Branches -> Add rule. To speed up your tasks by leveraging Nx's powerful scheduling and caching capabilities. (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? Support Monorepo. css 879 Questions Monorepo example with pnpm. Let's dig into it! Note: The examples of this post are available at this Github repository. When packages are published, it automatically changes the references to the real versions or semver ranges, so we don't have to care about that. Dig in! # pnpm-workspace.yaml packages: - "admin" - "client" - "shared" It may have no sense in a real project, but it is useful for this example: Let's add also a new task dependency, so before running E2E tests it will also run the build script of all dependent projects. Requirements for a good workflow, Building a Node.js monorepo with Pnpm and Nx, CI/CD for Pnpm and Nx monorepo using Github actions, # all packages in subdirs of packages/ and test/, Testing localStorage exceptions with Cypress. A: When you get into managing all this stuff, man its not easy. We are going to create a repository containing two simple projects that theoretically would be published to NPM, and a project containing E2E tests of both packages integrated. Note that the dependencies of all packages in the repository are installed when pnpm i is executed in the root folder. 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. In this course he'll mentor us through building confidence with monorepo workflows and new tools, and build faster and more efficient workflows. It can help speed up development for larger projects, makes it easier to share code, and act as a single source of truth. This is a step-by-step guide, but you can directly check the repository code while reading for a faster approach. Today, we are happy to announce the release of Nx 10.4 that includes the introduction of cleaner ESLint configuration, Pnpm compatibility, and more! You could store your packages depending of their type in different folders, for example. How to parse multiple div with same class name in a div in cheerio? However, it will be broken for consumers that pull it from a registry, since the dependency list is now incomplete so they have no way to download the new dependency. 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. It will build and test only the affected projects whenever a PR is opened or the code is pushed to release or main branches. 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. Web developer since 2002, working as a front-end specialist since 2009, and as a front-end architect since 2014. string 110 Questions 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. 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. It is called filtering in pnpm docs (see it here). Thanks for keeping DEV Community safe. 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. So, we will add a first job, getting the information and exporting it as a Github Action output. For that, we will use the Pnpm Workspace feature, that allows to reference workspace packages through aliases. My use case for a monorepo: static site generation A workspace must have a pnpm-workspace.yaml file in its root. Negative or Positive Number to 32 Bit Binary Data in JS. Both of them are executed using multiple Node.js versions. All we need is already built into npm and TypeScript. 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. Advertisement Answer It is called "filtering" in pnpm docs ( see it here ). tip 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. If we have twenty packages in the workspace, some of them containing a build command, and some others not, then should we create a build:affected script and execute it always before running the unit tests? It will ignore the skipped matrixes, because sometimes no unit-test matrix will be created, or no test-e2e will be executed, etc. Short story: you can use Nx easily together with your current Lerna/Yarn/PNPM/NPM monorepo setup. For allowing Nx to recognize it, we should add a project.json file to the project defining its type as "application", but this produces Nx not detecting the dependencies automatically in our simple example if we don't add more configuration such as TypeScript aliases. 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. Lets make a short recap in order to check if all of them have been met: There are still some points that could be improved. 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. 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. I wanted to bring awareness that this stuff is really accessible. Open up the file and add the following lines to it. npm pnpm Conclusion Okay so attempt #1 didn't quite work, but all the package managers have a feature called Workspaces, which npm describes like this: [Workspaces] provides support to managing multiple packages from your local files system from within a singular top-level, root package. Why a Pnpm and Nx monorepo? This special type of repository is known as a monorepo. If you used local npmrc in your Lerna repo, copy it to the use-lerna-repo root folder. We can add branch protection rules in order to require status checks to pass before merging. The code would remain in the release branch until the main project maintainer considers that it is ready for declaring a formal release (ideally often too). Both pnpm (as of v2.17) and Yarn (as of v1.12) support fast, concurrent installations in monorepos. All commands run through root; Use in host, hook up my monorepo to render run commands; Filter and recursive "install:all": "pnpm recursive install", If javierbrea is not suspended, they can still re-publish their posts from their dashboard. To bundle our code in every package, we can use lerna exec: lerna exec -- bili --config ../../.bilirc.js. Let's add one script to the root package.json file in order to provide an easy alias for doing it: Note that this script has to be executed in a Git repository to be able to compare changes. Unflagging javierbrea will restore default visibility to their posts.
