As you can see in the project graph above, there are four e2e test projects in the repo: one for each remote and one for the host. This does behave slightly differently from our usual Angular serve. That is, changes to host will update its bundle, but changes to remotes will not update. Connect and share knowledge within a single location that is structured and easy to search.

It's worth stressing that there's been no actual errors or breakages noted from our tests. Also, make sure you dont miss anything by. Please see the next section for this. This slowness It can be used in tandem with CD solutions that involve spinning up environments for different stages of the release process without having to rebuild the application at all. Angular based mfe's. Just create a module federation demo with nx and add tailwind to your host 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. And, if you have Nx Cloud turned on, you may never have to build domains you are not working in, because someone else in your team, or the CI machine itself, will have already built those remote applications, and youll get to take advantage of the distributed cache!! "styles": ["libs/ui/common/styles/globalTailwind.css"], I dont know if it is a elegant method to solve this problem but now my remotes apps and shell are using tailwind utilities classes in their html files. One possible usage for improving the startup times is to set eager to true just for the host.

Explain Like I'm 5 How Oath Spells Work (D&D 5e). This is our modified remote. It declares a separate root component (AppComponent) hosting a and imports RouterModule inside root module (AppModule). This is required for the Module Federation Plugin to expose the Module correctly. We can see if we navigate a browser to http://localhost:4201 that we see the login form rendered. 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. To do this, first we modify app.routes, removing its entry.routes lazy load, and adding our remote children routes to its array. Yes, because Angular will bundle the CSS for that component in the JS bundle, which is fetched correctly. You signed in with another tab or window. Module Federation provides a solution to the scaling problem by allowing a Single Page Application (SPA) to be sliced into multiple smaller I found a couple oddities in its implementation I'll spend some words about in a future article, maybe. Now, let's generate the Login application as a remote application. In the article Using Module Federation with (Nx) Monorepos and Angular by Manfred Steyer, from the module . Join Nx Core team members Colum Ferry and Juri Strumpflohner as they talk about Module Federation and how Angular Standalone Components fit into that.

Let's start with generating the Micro Frontend app structure and create Nx workspace;. 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. After running that command you'll see the following artifacts in dist folder. The required name property is the magic to link the host and remotes together. Well occasionally send you account related emails. 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. https://github.com/dale-waterworth/micro-front-end-react - localhost:3001, https://github.com/dale-waterworth/micro-front-end-angular - localhost:4201 (ng serve mdmf-profile), https://github.com/dale-waterworth/micro-front-end-container - localhost:3002. but for the purposes of this tutorial, we'll keep it simple. The CD pipeline only ever needs to replace a JSON file on that environment with one that contains the correct values for the deployed locations of the remote applications. We can see that, despite being a single application, there are already some clearly defined domains (or slices) within our application. 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. Note: Both commands serve the whole system. Try to use tailwind in federated modules or its child libraries. All the remotes in the case are loaded and are build. How to design a schematic and PCB for an ADC using separated grounds.

If nothing happens, download GitHub Desktop and try again. loadChildren: () => If a component in a remote application uses classes from a global stylesheet, then that global stylesheet only exists on the remote application's location, unless the same classes/stylesheet are used in the host application. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Nx is open source, check the code on GitHub, Prepare applications for deployment via CI, Setup Module Federation with SSR for Angular and React, Advanced Micro Frontends with Angular using Dynamic Federation, Publishing Storybook: One main Storybook instance for all projects, Publishing Storybook: One Storybook instance per scope, Publishing Storybook: One main Storybook instance using Storybook Composition, Disable Graph Links Created from Analyzing Source Files, Setup incremental builds for Angular applications, Find the Last Successful Commit in Azure Pipelines, Include All package.json Files as Projects. This allows Module Federation to take the remote's metadata in consideration when negotiating the versions of the shared libraries. 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. It does a great job though, raising the coder from writing a lot of boilerplate and, considering I'm not exactly an expert in this field, there's the chance some of the things looking like "flaws" to me, were real solutions for cornercases or common use scenarios I didn't think of. You can learn more about this concept here. The Angular Module that is resolved and rendered still lives on the remote server, but Module Federation will still resolve this correctly! It prompts: "What to create in the new workspace" select empty and Enter; "Use Nx Cloud?"

If you use Module Federation to speed up your CI and improve your local development, and not to deploy different remotes independently, you need to create implicit dependencies from the host to all the remotes. When using Nx, you rarely have to build all of them because most of the time you work on one remote, other remotes will be retrieved from cache. Publishing Storybook: One main Storybook instance for all projects; Publishing Storybook: One Storybook instance per scope; As shown in the last example, we also added another property: pinned.

There . This works best, if the host always has the highest compatible versions of the shared dependencies. Now, let's continue by creating an empty Nx workspace. In module federation with webpack 5, it is possible to share dependencies between the Microfrontends. Married with 2 amazing kids. npx nx g @nrwl/angular:setup-mf ourapp --mfType=host, npx nx g @nrwl/angular:remote featureA --host=ourapp, npx nx serve ourapp --devRemotes=featureB, npx nx g @nrwl/angular:host shell --remotes=featureA,featureB,featureC. The above command serves host in development mode, whereas the remotes are built and served statically. Whether Module Federation makes sense for your team depends on the size of your application. If we browse to the standalone remote served app, by default reachable at host_port+1, thus on http://localhost:4201 for a classic setup, we'll see our remote content, the blue square, immediately rendered and no host's anchor element, as expected. It points you to the important aspects of using Module Federation. Co-Founder of GrammarGuru. I will take for granted the creation of a Module Federated Angular app under Nx. If, say, someone is working on shop, they will get the cart and about builds from the cache. This is great for running e2e tests in CI and shared-components. As always, if you are looking for enterprise consulting, training and support, you can find out more about how we work with our clients here. This means we sometimes spend more time waiting on the application to build than actually writing code. Implementing Module Federation with Angular 12 To use module federation we need to run below command in all the related applications. Note: We discourage users from overriding the shared configuration. However, with any UI library (TailwindCSS) or CSS setup that uses the Purge PostCSS plugin, then this becomes a more involved issue, as the generated CSS bundle for the host application will only look at direct dependents. You can see this behavior locally if you serve the host twice. Big thanks to the following people who helped to make this possible: Module Federation allows loading separately compiled and deployed code (like micro frontends or plugins) into an application. Powered by Coffee. In the end we can appreciate the result of our efforts, looking at our blue square rendered a single time for any serving methodology: I think Nx support for Angular standalone components federation is still a bit "unripe". As our Angular applications grow, building the application takes longer and longer. Version-Mismatch-Hell where different applications are deployed with different versions of shared libraries can lead to unexpected errors. Here we got merely a square div coloured in blue. It helps to achieve the use case of "Build once, deploy everywhere". You can now continue developing as normal, but everything will just be a lot faster, and youll have Module Federation set up in your Workspace, which puts you in a good position to then take it further and truly go down the Micro Frontend route if that is your desire.
