Posted on Dec 1, 2022

This gives you a good developer experience: the whole app is available, but only the part you are working on is Are you sure you want to hide this comment? . It allows the user to specify which remote applications should be served with the host. This example loads a microfrontend into a shell: Please have a look into the example's readme. . It helps to achieve the use case of "Build once, deploy everywhere". One possible usage for improving the startup times is to set eager to true just for the host. When to claim check dated in one year but received the next. Again, if you don't use Nx Cloud's Distributed Tasks Execution using Module Federation will be slower than building everything in a single process. This way the same route referring to entry component will be correctly rendered just once both for Shell setup than for independent remote serving. Having a suite per remote allows us to distribute e2e tests across machines to make them faster and to only run the suites that could be affected by a PR. We wont address this in this article, but it is highly recommended to use this along with Module Federation to allow for the cache of your remote applications to be shared amongst teammates and CI, further improving your build times. We just need to run. By passing --devRemotes, you configure what parts of it you will be changing. The dynamic import makes Module Federation to load the shared libs. To do this, first we modify app.routes, removing its entry.routes lazy load, and adding our remote children routes to its array. That is because they are specified in the module-federation.config.js file. We want to change this so that the Dashboard application can make a network request at runtime to find out the deployed locations of the Remote applications. Suggestions cannot be applied while the pull request is closed. Select "Integrated Monorepo" then "Angular". You can also split it horizontally by making some libraries buildable. So your serve command now can take a minute instead of 10 minutes and only require 4GB of RAM instead of 16. Why the issue doesn't occur with old NgModule-based remotes setup instead of standalone components?

This works best, if the host always has the highest compatible versions of the shared dependencies. in the repo, but they could have hundreds of libs), one working on cart, and one working on shop. served and watched. Once at the start, then anytime a shared dep between it and a remote application changes. Here is what you can do to flag this-is-angular: this-is-angular consistently posts content that violates DEV Community's This function is an abstraction on top of webpack's ModuleFederationPlugin with some Nx-specific behavior. Try to use tailwind in federated modules or its child libraries. Changes to the bootstrap of application to fetch the Micro Frontend Manifest, set the Remote Definitions and load the Login application correctly. We can see that, despite being a single application, there are already some clearly defined domains (or slices) within our application. For both applications, the generator did the following: The key differences reside within the configuration of the Module Federation Plugin within each application's module-federation.config.js. Distributed task execution, which simplifies your CI/CD setup, and speeds up your builds. hey @sdedieu. The result of each build process can be cached independently. This graph should be explanatory enough: As the purple highlighted labels emphasize, the path to rendering of the entry component for independent remote serving encounters two different locations asking for it. You signed in with another tab or window. Please have a look at this article series about Module Federation. config has been created module. Micro-Frontends with Module Federation using Angular and Nx Nx - Smart, Fast, Extensible 9.24K subscribers Subscribe 128 Share 11K views 1 year ago Building on top of the work down by Manfred. At this point, we usually look to split the monolithic application into smaller subsections. Because the Host application is using Dynamic Federation, the new Remote will be added to the Hosts module-federation.manifest.json. and Angular examples. In order to make module federation work, we need to bootstrap the app asynchronously. Building A Plugin-based Workflow Designer With Angular and Module Federation Getting Out of Version-Mismatch-Hell with Module Federation Using Module Federation with (Nx) Monorepos and Angular Pitfalls with Module Federation and Angular Multi-Framework and -Version Micro Frontends with Module Federation: Your 4 Steps Guide The new withModuleFederationPlugin helper that has been introduced with this plugin's version 14 does this by default. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. You can find out more about that here. I'll let it sit for some time while we assess the situation but if no good solution comes for this, I'll close the issue. In the next section, we will see how Nxs generators can be used to automate a lot of this process for us! This tells the generator that this remote application will be consumed by the Dashboard application. This repo demonstrates the latter. Dynamic Module Federation is a technique that allows an application to determine the location of its remote applications at runtime. Lets say we have a single Angular application in an Nx Workspace with the following architecture: If you are not already using Nx, and want to take advantage of this, consider migrating to Nx first. It's a known error output, but it doesn't actually cause any breakages from as far as our testing has shown. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I added another remote component. What does a client mean when they request 300 ppi pictures? That entry component is actually both declared both routed. You can then run nx deploy host to see the application running on http://localhost:3000. Software Engineer @nrwl . Create three remote applications for each feature listed, Wire up the remote applications to the host application. The flow Nx relies on starts with the usual serving of an index.html built upon a template like this: In place of Angular-cli generated selector assigned to AppComponent, body has been populated with our custom remote entry component's selector. . There are some costs to slicing an application through Module Federation: Nx provides the best experience for teams that want faster builds, but want to also minimize the downsides that come with Module Federation. The maintainer of the plugin commented on this same issue in a discussion on the webpack repo here: module-federation/module-federation-examples#714 (reply in thread). Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. I'll add the blocked with third party tag to this issue. Hence, you don't need to do a thing. The host application references the three remotes by their names. Powered by Coffee. This is different from having different versions of the app for every team. To show how, we split the application into 3 remotes: about, cart, and shop, and the host project. It points you to the important aspects of using Module Federation. Now that we have our applications generated, let's move on to building out some functionality for each. This file is the main configuration for the host, and you'll see module-federation.config.js for the generated remotes as well. Angular Universal will switch to CSR after the initial page load, which means if we were to click on the login link, it would use CSR to render that page. It's worth stressing that there's been no actual errors or breakages noted from our tests. Then, when loading the remote Module, you set to mention the remoteEntry property anyway, as it also acts as an internal identifier for the remote: Let's assume, you have an Angular CLI Monorepo or an Nx Monorepo using path mappings in tsconfig.json for providing libraries: You can now share such a library across all your micro frontends (apps) in your mono repo. The agreed solution is that every domain in the application will become its own application owned by a feature team, and theyll all be composed in the host application. Youll note that this will generate the same output as the Login Remote application in the previous guide. The module-federation-dev-server executor is reserved exclusively for use with host Module Federation applications. Once unpublished, this post will become invisible to the public and only accessible to Gianpiero Errigo. 1 - Create Blog; 2 - Create CLI; 3 - Share Assets; 4 . We can do this easily with: You'll be prompted for a preset. Running dep-graph in the project where modules are imported via module federation, federated modules are not marked as a dependency. The issue is around exposed components using any form of global stylesheet. Nx Devtools Component-First Architecture with Standalone Components and Nx Colum Ferry in Nx Devtools Using NgRx Standalone APIs with Nx Colum Ferry in Nx Devtools Generating Standalone Component-based Angular Applications and Libraries with Nx Colum Ferry in Nx Devtools Setting up Module Federation with Server-Side Rendering for Angular Help Or the parallel start of all apps: nx run-many --parallel --target=serve --projects=host,cart,blog,shop --maxParallel=100. Webpack 5 introduced the Module Federation Plugin which has rapidly become the go-to solution for splitting large monolithic applications into smaller composable pieces. nx.json package-lock.json package.json tsconfig.base.json README.md Speeding Up Angular Builds Using Module Federation WebPack module federation can be used for developing independently deployable microfrontends and for speeding up the build commands. Our login application is complete. To keep entry.routes inside our compilation unit we move its import outside of routes definition, so it will be still compiled and exposed by our federation configuration, but ignored by our router during independent serving: Now we can edit entry.routes, enriching its only route with an array of children, simply importing the one defined in app.routes. Beginning with version 14, we use a more steamlined configuration, when using the above mentioned --type switch with one of the following options: remote, host, dynamic-host. For further actions, you may consider blocking this person and/or reporting abuse. Angular Universal (Server Side Rendering) Since Version 12.4.0 of this plugin, we support the new jsdom -based Angular Universal API for Server Side Rendering (SSR). We'll touch on this later in this guide. This does behave slightly differently from our usual Angular serve. Unfortunately, there isn't much we can recommend beyond trying to stick to component-level styles, shared component libraries and being vigilant of this gotcha. to your account. You can see what the CI does by viewing the sample pull requests in each repo. WebPack module federation can be used for developing independently deployable microfrontends and for speeding up the What it illustrates is a system built by 3 teams: one working on about (we have a single lib Both of them are Micro-Frontends, meaning they are capable of running on their own, even the remote one. code of conduct because it is harassing, offensive or spammy. }, At this time, we'll also want to remove them from ourapp. For this to work, the state within UserService must be shared across both applications. I guess I found a way to workaround this situation without using apply in each component. However, developers in your organization are complaining that they are waiting an ever-increasing length of time for their builds and serves to complete. Updated on Jan 23. With Nx Cloud enabled, a large set of builds can be skipped entirely when running the application locally (and in CI/CD). You should see a success message like this in the terminal: Lets open a new tab in our browser, and open Network tab in the DevTools. This is great for running e2e tests in CI Note, for this to work well in practice, you should get cache hits for other remotes most of the time (rebuilding every remote separately is slower than building everything together), which means that you should have some distributed caching set up. After using these Schematics, we have to enable asynchronous bootstrapping again: As now we have both, Module Federation and Angular Universal, in place, we can integrate them with each other: Adjust the used port in the generated server.ts file: Now, you can compile and run your application: Please find an example here in the branch ssr.

We don't recommend making all libraries in your workspace buildable--it will make some things faster but many other things slower. blocked: third-party scope: angular Issues related to Angular support in Nx type: question / discussion. Big thanks to Michael Egger-Zikes, who came up with these solutions. If you do not have an existing application that youre splitting out into multiple slices, but rather you have a new application and you wish to take advantage of the Module Federation architecture, Nx can help you quickly scaffold out the host application as well as all the remotes you need with one command: Running this command will do the following: Now you can run nx serve shell and it'll build and serve the full architecture! The remotes loaded later can reuse these eager dependencies alothough they've been shipped via the host's bundle (e. g. its main.js). Find centralized, trusted content and collaborate around the technologies you use most. To make thing barely functional, our host app consists of a single dumb component with two lines template: Just an anchor linking to the remote, and a router-outlet under which the child will be rendered. How to work with and setup Module Federation with Nx. After this, navigate to http://localhost:4200. I created tailwind.config.js in root level of monorepo like that, then I removed of my shell and remote apps all styles using, and I also removed their own tailwind.config.js, So I created a lib called ui/common with globalTailwind.css that uses tailwind config. Publishing Storybook: One main Storybook instance for all projects; Publishing Storybook: One Storybook instance per scope; By default, it takes the package.json that is closest to the caller (normally the webpack.config.js). Hence, we also get Module Federation out of the box. In the article Using Module Federation with (Nx) Monorepos and Angular by Manfred Steyer, from the module . As a result, the worst case scenario build time is: buildOf(shared-components) + buildOf(slowest remote) + buildOf(host) which in practice ends up being significantly faster than building the whole system (often 3-4 times faster). Inside our remote's module-federation.config.js there's the mapping for arguments passed to that call: So: the host's Router will look inside remote's entry.route.ts to know which child routes it could render. `, ` To learn more, see our tips on writing great answers. You can see this behavior locally if you serve the host twice. In a large enough system (with say 10-20 remotes), you will often only work on 1 of them, but you still need the rest of : [CommonModule, FormsModule, RouterModule.forChild(remoteRoutes)],
