Updated on 2021-12-23 for Angular 13.x and Nx 13.4 and upwards We will be overriding the webpack version in package.json and yarn is required to override the web pack version for angular cli. There are six main procedures you'll need to follow. This only matters for local development. localhost/:1 Uncaught TypeError: Failed to resolve module specifier "mfe1@localhost:5000/mfe1remoteEntry.js". Thanks for keeping DEV Community safe. However, I can tell you: Ive seen both working in huge real-world projects. This guide shows how you can adjust to this. To make using it a bit easier, the @angular-architects/module-federation plugin wrap it nicely into some convenience functions. For this, Nx provides linting rules. In the previous article of this series, Ive shown how to use Webpack Module Federation for loading separately compiled Micro Frontends into a shell. I am basing my work on Manfred Steyer's Module Federation Plugin Example repo, which uses Angular CLI. To put it in another way: We trade in some freedom to prevent version conflicts and increased bundle sizes. It should run in default port 4200. so let's run bellow command to create admin module: ng g module admin --routing. This is possible because of the runtime API provided by webpack. If an application (or library) hasnt been changed, its neither retested nor relinted. You can still deploy Micro Frontends separately and thanks to linting rules provided by Nx Micro Frontends can be isolated from each other. To run from a git checkout locally, remove all of the proprietary example directories and then run yarn at the repo root. As it comes with respective schematics, you can easily ng add it to your CLI workspace: In your tsconfig.json in the project's root, adjust the path mapping for auth-lib so that it points to the libs entry point: As most IDEs only read global configuration files like the tsconfig.json once, restart your IDE (Alternatively, your IDE might also provide an option for reloading these settings). Make sure any module dependencies your shared services have are also shared. Each team can concentrate on their Micro Frontend. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. There are no errors or anything -- things just don't work like you expect. Why would a fighter drop fuel into a drone? One is logging-in users and the other one displays the current user. (c) Manfred Steyer, 6 Steps to your Angular-based Microfrontend Shell. With you every step of your journey. On Clicking each link we load a module from the remote application and use it in our shell application. This feature module will be loaded as Microfrontend in the host application in the subsequent sections. It should run in default port 4200. A traditional approach uses a separate repository per Micro Frontend: This is also a quite usual for Micro Services and it provides the following advantages: Micro Frontends and hence the individual business domains are isolated from each other. Why is geothermal heat insignificant to surface temperature? The picture above show two different use cases where Module Federation brings advantages. Please ignore depreaction warnings. After a browser window with the shell opened (http://localhost:5000), click on Flights. The mfefeature module is lazy loaded. Each Micro Frontend can be separately deployed. This is just pleasant to read. We also have some cons but considering the tradeoff, depending on your use-case microfrontends are a powerful tool. To find out about the small differences for lower versions of Angular and for the migration from such a lower version, please have a look to our migration guide. The following image displays the idea described in this article: For all Micro Frontends the shell gets informed about at runtime, it displays a menu item. However, if you feel that the disadvantages weigh heavier, the next sections show an alternative. They are used by both, the shell and mfe1: Also, the auth-lib stores the current users name in a service. However, when dealing with it, several additional questions come in mind: Our free eBook (about 100 pages) covers all these questions and more: By using monorepos for Micro Frontends you trade in some freedom for preventing issues. May-12-2021 Update: Added Dockerfiles for both the projects. see https://github.com/manfredsteyer/mf-angular-13. run successfully command, it will create files as like bellow path: We have to use those aliases, but tell webpack where to find the libraries by using the import option. This is post 3 of 10 in the series Module Federation, Updated on 2021-08-08 to address Angular CLI 12.x Switch into the shell project and open the file projects\shell\webpack.config.js. It supports all Angular Devkit builders and schematics. Also, if we switch out the manifest for a dynamic REST service, we could implement strategies like A/B testing. Instead, the result is taken from the Nx build cache. For this, Ive updated my example to fully work without NgModules: Please find the source code here (branch: standalone-solution). The ScriptedAlchemy example makes it seem like I need to reference my shared library in my shared library array in the webpack.config.ts files. Redeploying all applications that have been changed or affected by a (lib) change is vital, if you share libraries at runtime. This is needed since Angular CLI 13. I contacted a professor for PhD supervision, and he replied that he would retire in two years. How should I respond? We can only make a guess if the future version of Angular will support the micro frontend architecture from out of the box. As in the previous article, we are using the @angular-architects/module-federation plugin to enable Module Federation for the shell and mfe1. As the Url mfe1/Module does not exist at compile time, ease the TypeScript compiler by adding the following line to the file projects\shell\src\decl.d.ts: Hint: You might use two terminals for this. I have created a shell and remote in Angular 15, using @angular/cli as multi-repo app. Is there such a thing as "too much detail" in worldbuilding? This configuration is copied during the creation of the docker image. please refer the image and help me to solve this issue. Whats New in our Module Federation Plugin 14.3? There are multiple tools to glue them together, like Module Federation and NX monorepos. Hence, lets comment out the remote section there: Also, in the shells router config, we need to switch out the dynamic imports used before by calls to loadRemoteModule: The loadRemoteModule function takes all the key data, Module Federation needs for loading the remote. If we wanted to switch to Dynamic Federation, we would again use loadRemoteModule instead of the dynamic import: So far, weve seen how to decompose a huge client into several Micro Frontends that can even use different frameworks. Nearly all of the disadvantages outlined above can be prevented by putting all Micro Frontends into one sole monorepo: Now, sharing libraries is easy and there is only one version of everything, hence we dont end up with version conflicts in the browser. Do the same for the microfrontend. Hence, we can expose and lazy load such router configurations. // remoteEntry: 'http://localhost:3000/remoteEntry.js', // Authentication for **honest** users TM. As EcmaScript modules can be directly imported, there is no remoteName anymore. Basically if you want to create an application to book tickets for travel, movies, events etc. Changes to one part of code in one application will not cause bugs in another application. Generally speaking, we're using this to point to code that is bundled into our app by Webpack. This will set up Webpack's Module Federation Plugin for the application and configure it as a host application, ready to consume remote applications. The next sections discuss how to do the same with libraries of a monorepo. How can we avoid pitfalls when working with Module Federation. I have got the solutions to this at: Interesting article. I hereby agree that software architect can process my email address for the purpose of sending the newsletter. For this, you might want to extend the manifest: Besides remoteEntry, all other properties are custom. However, we are monitoring this situation and providing a solution as soon as these issues are fixed. Ive repeated this for mfe1 (scope:mfe1) and the auth-lib (scope:auth-lib). Images, CSS, JSON, WASM, and anything else can be federated.

After adding Nx to your workspace, running ng will run the wrapped Angular CLI that goes through Nx. This wouldn't have been more clearer for beginners. Could a society develop without any time telling device? The Microfrontend Revolution: Module Federation with Angular; Dynamic Module Federation with Angular; 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 Here to get the module we use a helper method from the package we added earlier called loadRemoteModule where we pass the proper remoteName, remoteEntry & exposedModule which we used in the webpack.config.js file of remote applications. I tried to run the custom builder but it is not install properly. Here, remove the registered remotes: Open the file app.routes.ts and use the function loadRemoteModule instead of the dynamic import statement: Restart both, the shell and the micro frontend (mfe1). Besides checking against linting rules in your IDE, one can also call the linter on the command line: The good message: If it works on the command line, it can be automated. So, if you run into this issue take a look at your dependencies and make sure you're sharing everything you need. Module federation will work with any type of file that youre able to import, that Webpack understands how to process. They are a temporal issue in the current CLI beta when using webpack 5. Credit: This post is based on this article written by Manfred Steyer. You've implemented your first Module Federation project with Angular! I am basing my work on Manfred Steyer's Module Federation Plugin Example repo, which uses Angular CLI. For this, you can adjust the project.json in the apps or libs folder. Great, thanks a lot for pushing it! Use the hyperlink flights in the shell to load mfe1. How can we make sure, the solution is maintainable for years or even decades? [webpack-dev-server] Live Reloading enabled. or higher, Advanced: Dynamic Federation with Script-based Remotes, Advanced: Static Federation with Script-based Remotes, Advanced: Opting-out of Using EcmaScript Modules, https://github.com/manfredsteyer/mf-angular-13. (Underground Edition), 4 Easy steps to train your AI model and create personal Avatar generator , Create Microfrontend Application with feature module, each remote could have nested routes defined in app-routing.module.ts respectively which could load modules defined in the remote, the host should only load the remotes' app.module.ts lazily. However, because of a bug in Angular Universal 13, SSR is currently not supported for Angular 13. Dynamic Federation means, we dont want to define our remote upfront in the shells webpack.config.js. This route will later be used for loading the separately compiled microfrontend. Its used in the template to dynamically create the menu items: Now, lets try out this "dynamic dynamic" solution by starting the shell and the Micro Frontends (e. g. with npm run run:all). There are multiple things we can do here like giving shared modules so that we dont have duplicates and version mismatch etc. Thanks. Dies ist Beitrag 9 von 10 der Serie Module Federation, Dies ist Beitrag 9 von 10 der Serie Module Federation, Updated on 2022-06-09 to address Angular CLI 14.x. Also, the values of the key/value pairs in the manifest, are put into the remotes field. It comes in handy if you load the data from somewhere else. It should look like this: There are lots of good articles available online in case you want to deep dive into the topic. Unflagging manfredsteyer will restore default visibility to their posts. Generate single-spa-props.ts in src/single-spa/. The demo project used contains a shell and two Micro Frontends called mfe1 and mfe2. However, in some situation you might not even know about the number of Micro Frontends upfront. Beginning with version 13, the Angular CLI compiles emits EcmaScript modules. I checked the bundles with the webpack bundle analyser and saw that the Shared modules are duplicate in main and polyfills. In this training, you will learn from well-known insiders and experts from the very beginning, using many examples, how to successfully develop modern applications with. I think Zack Jackson, one of the authors of Webpack Module Federation said it best: A scalable solution to sharing code between independent applications has never been convenient, and near impossible at scale. At the end, you find a property tag, Ive set to scope:shell: The value for the tags are just strings. Please note that the name of the dockerfile is "HostDockerfile". Instead, you can also go with the switch --projects to just start a subset of them: --project takes a comma-separated list of project names. This also effects how entry points for Module Federation are generated. After creating successfully app, we need to create module using angular cli command. This must be because the shared services had 'unshared' dependencies. Hence, Module Federation gets all the required metadata for fetching the Micro Frontends on demand. Inside this folder create a file "default.conf" and copy the below commands. For Visual Studio Code, this can be installed via an extension. Start Micro Frontend (remote): ng serve mfe1 -o. To fix the error, we will create decl.d.ts under host and declare the module, Step 3: Add route for mfe in Appcomponent, In app.component.html, make the following changes, you will able to navigate to the mfe1 which is actually running in localhost:5000, Option 2: Dockerize the apps and run in containers, *Step 1: * Create nginx default configuration file. In this case, only the manifest is loaded: setManifest(): This function allows to directly set the manifest. According to the underlying CFP, this function will be called configureRouter. I'm encountering the same issue, works locally, but when deployed to different server I'm getting CORS issues. Most tutorials on Module Federation and Angular expose Micro Frontends in the form of NgModules. Step 6: Create containers for host and mfe1, Run the below commands to create and run the containers. However, with the introduction of Standalone Components we will have lightweight Angular solutions not leveraging NgModules anymore. Each team has the maximum amount of freedom in their repository. However, we can improve this solution a bit. Hi. DEV Community 2016 - 2023. Happy Learning. The name of the docker image is host. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. If you find out that the advantages of this approach outweigh the disadvantages, you find a solution for mixing and matching different frameworks and versions here. both app.component.ts files are identical. However, you can use these commands with the switches --base and --head. The main difference to the result in the previous article is that now the shell informs itself about the Micro Frontends at runtime. It either compiles and runs and creates two instances, or it fails to compile citing a missing module depending on how i mess up my configuration I'm sure. We will be using Webpack 5 Module Federation with Angular 11. Have you ever considered using multiple frameworks or framework versions for one application? As usual in Nx and Angular monorepos, libraries are referenced with path mappings defined in tsconfig.base.json (Nx) or tsconfig.json (Angular CLI): The shell and mfe1 (as well as further Micro Frontends we might add in the future) need to be deployable in separation and loaded at runtime. This hands-on example is a continuation to the following two articles where I explained how Micro Frontends work with Webpack5 and Module Federation. Adjust it as follows: Is there documented evidence that George Kennan opposed the establishment of NATO? Asking for help, clarification, or responding to other answers. Once in place, they give us errors when we directly reference code belonging to another Micro Frontend and hence another business domain. This is the foundation of Micro-Frontend Architecture and the Module Federation Plugin makes implementing such an architecture much . Hence, teams can separately evolve their Micro Frontend. In this post, we will implement Micro-Frontends in Angular using Webpack 5 Module Federation. Beyond the covers, it handles Module Federation in a very similar way as the plugin used here. Archiving this with an npm package is not that difficult.
