Next, update the navigation button for Profile in the shell application to route to the correct path. For, smaller and non-complex applications that involve a few modules/pages and are not complex, the traditional approach is the most viable solution. This approach is only recommended for instances of large and complex applications development where the modules and pages are dependent on each other and it is difficult for different teams of developers to work on the same application simultaneously. If this is achieved Angular should also to be able to support Micro-Frontends. But as applications tend to become complicated over time, demanding on-the-fly scalability and high responsiveness, a micro-frontend architecture using Angular elements serves as the need of the hour in fulfilling these criteria. Reusability: You will be able to use code in multiple places. Since this application is a remote, well update the snippet of code under the comment: The defaults are mostly correct, except we have a module, not a component that we want to expose. Once unpublished, this post will become invisible to the public and only accessible to Anthony Viard . Step 14: Lets hit refresh and open the browser console: What if we need to send data from one web component to another? Before you begin, youll need a free Okta developer account. First of all, we need to create utils for module federation, where we can load remote modules from other apps. Lets see how to proceed using Angular and lets see how to create our first micro frontend. This post is part one in a series where well build an e-commerce site using Angular and micro frontends. There are three ways of how you can do that: Client-side composition; Edge-side . However, as applications get more complex over time, requiring on-the-fly scalability and high responsiveness, a micro-frontend design based on Angular components is becoming increasingly effective in addressing these requirements. Step 1: Install Angular Cli npm install -g @angular/cli Step 2: Create a new project ( {project-name}-wc-feature) ng new phoenix-wc-wiki-ngx When the terminal asks us, "Would you like to add Angular routing?" we choose "No." Step 3: Add the @angular/elements and ngx-build-plus ng add @angular/elements ng add ngx-build-plus The shell application code doesnt know about the Profile module, and TypeScript needs a little help. In this digital time, the form of a web application is getting larger and more sophisticated, so frequently they need to be handled by multiple teams. // './Component': './projects/shell/src/app/app.component.ts', // important external libraries to share, "(isAuthenticated$ | async) === false; else logout", "flex items-center transition ease-in delay-150 duration-300 h-10 px-4 rounded-lg hover:border hover:border-sky-400", ./projects/mfe-profile/src/app/profile/profile.module.ts, // other Angular libraries remain in the config. Prolongacin Amricas 1600, Second Floor, ( also Av. Simple learning: Smaller modules are easier to learn and understand for new developers entering the teams, than a monolithic architecture with a huge code structure. The shell application serves on port 4200, and the mfe-basket application serves on port 4201. The shared library contains code and application state we want to share across the site. Each team is dedicated to and specialized in a specific area of business or purpose. You might be able to further categorize these features into domains, each of which could be a separate micro frontend, also known as a remote. This module we can use is like a lazy-loaded module in our shell app. Step 10: Now we have two web components. As mentioned earlier, this approach to Micro Frontends, works well for the use case or requirements mentioned above in the blog, and for customer facing websites which demand much better user experience without any kind of page loads after the initial page load, you will have to look for other options or come up with your own solution, as so far, there has been no official support by Angular for implementing Micro Frontends. The Need for Angular Micro Frontends Architecture, 3. Micro Frontends is an architecture style used to overcome the limitations of monolithic frontends. Here we go. Each team is autonomous with separate frameworks and codebases, which lead to ambiguous browsers. Hire angular developers from us to create frontend applications that are faster, more scalable, and more user-friendly than ever before. Schema validation failed with the following errors:Data path .budgets[1].type should be equal to one of the allowed values. Open projects/mfe-profile/src/app/profile/profile.component.ts and edit the component to add the two public properties and include the OktaAuthStateService in the constructor: Next, open the corresponding template file and replace the existing code with the following: Try running the mfe-profile app by itself by running ng serve mfe-profile --open in the terminal. Micro-frontend architectures aren't THAT complicated. We have a built a web application called Control Center, it is basically a centralised console used by our internal teams to support operations in our services - Pharmacy Delivery, Tele-Consultation, Insurance, Labs and others. As Iframe has its context and sharing data with a parent or other webpage becomes more difficult and all operation needs to be done using Global context and Objects i.e Window object of the browser and that makes the application more vulnerable. declaration phoenix-wc-wiki-ngx/src/app/app.module.ts. We can update the code to incorporate the profiles micro frontend. Open app-routing.module.ts in the shell project and update the routes array as shown below. This is what we call micro frontends. Open the src/.html file and change the content to use the custom-element instead of the initial value. For the most part, the Control Center app relies on the server state for its state management. Hetzel Cordoba is a software engineer who graduated from the University De Los Andes in Bogot, Colombia. In the last step, it is the same main container in.html which we saw in the first step. Run the below Command with Options at the root of the repository level: Here we are creating a wrapper application that will represent/wrap all different domain applications under a single Base URL, here we have used the single-spa root config option as the project already exists and we need to create only a wrapper. As early adopters of this topic, we bring in our experience collected in numerous consulting projects during the last years. Manfred Steyer is a Google Developer Expert (GDE) for Angular and Tursted Collaborator in the Angular team. Step 1: Create Root / Wrapper Application, Step 3: Add Existing Apps in Angular Micro Frontends Architecture. in pure microfrontends, one frontend could be in Vue, and another in Angular, and you'd have some build process to export them as a Web Component The framework you use shouldn't impact how your microfrontends are designed as the whole point is there's a separation of concerns between the services so should be framework agnostic. angular, Address:8001 Arista Pl, Ste 600, Broomfield, CO 80021, Address: Sabana Business Center 10th Floor, Bv. Ready to embrace the power of Angular Micro frontends? We need to finish configuring that. A minimal, self-contained version of the Angular framework will be injected as a service to support the component's change-detection and data-binding functionality.". You will see output like the following when its finished: NOTE: You can also use the Okta Admin Console to create your app. The good thing is, this does not apply with the micro-frontends as code sharing is not required for every component. The index.ejs file loads this config file. window.addEventListener('phoenix-wc-wiki-ngx-ce-data-sent-test', this.customEventListenerFunction, true); implements OnInit, OnChanges, OnDestroy {, ngOnDestroy():void{window.removeEventListener('changeNameToCustomEvent', this.customEventListenerFunction, true);}, After we generate the builds and hit refresh to. Install the Okta CLI and run okta register to sign up for a new account. As its a shared code, regression testing is needed to make sure other departments functionality is not impacted and this makes the release process too slow. All the code is available at the repository: https://github.com/avdev4j/ng-social-card, Find more micro frontends videos on our YouTube channel: https://www.youtube.com/c/EntandoVideos, Join us on Discord to share and learn about Composable apps: https://discord.gg/SdMCvyzzHm. Well use a starter code to make sure we focus on the code thats specific to the micro frontend. Prolongacin Amricas 1612, Sixth Floor ), Col.

The main goal of micro frontends is to break the complete website into different web components that dont affect the user experience, allowing the user to start interacting with the individual components as they load on the page. Basically, Web Components need 4 specifications: Modern Javascript frameworks offer some solutions to easily create a web component, using a custom element, leveraging all the framework features, and creating small business-oriented apps. Step 4: Comment the bootstrap property in the @NgModule declaration`, add the AppComponent to entryComponents, and add the custom element in phoenix-wc-wiki-ngx/src/app/app.module.ts. Open projects/shell/src/decl.d.ts and add the following line of code. Open projects/mfe-profile/src/app/app-routing.module.ts and add a new route for HomeComponent. The same approach as for the Register page, but with personal webpack configs: Main app that loads all separated micro frontend modules into one app. As the Config file is a text file only, its easy to add/update and remove the mapping of route and landing page details. Install Static-Server to test the component, Run the command in the folder dist/phoenix-wc-wiki-ngx, Repeat the same process to create another web component called phoenix-wc-wiki-ngx-lt. Now we have two web components. They're both powerful, well-supported, and actively developed by their respective communities. If youre still over the fence about the need to adopt the micro-frontend architecture, lets take a closer look at what micro-frontend development can mean for your web apps: Each app integrates and deploys separately, making the CI/CD process a lot easier. (Currently, there are 12 MFEs). Currently the routerLink configuration is routerLink="/", but it should now be. You can reach us directly at developers@okta.com or you can also ask us on the At Entando, we believe the future is composable and so using micro frontends will help to share business components across teams, companies, and communities to use them and build applications. Smaller, more cohesive and maintainable codebases, 3. Step 8: Run the command in the folder dist/phoenix-wc-wiki-ngx. Join the DZone community and get the full member experience. We will keep you posted on the developments in this regard. Lets start with shell. With this we will get into the perils of shared memory communication and used as a lost resort. When building large apps, most enterprises tend to share code across features but may lead to scaling issues later when bugs and interdependency over the app grow bigger. Replace it with the following: Open projects/mfe-profile/src/app/home/home.component.html and replace all the code in the file with: Finally, we can update the code for the profile. ie were not maintaining any state in local storage. Since version 14, Nx provides out-of-the-box Module Federation support to both React and Angular. The front-end is divided into its multiple functions or parts. How the Angular Micro frontend Architecture is different from Traditional architecture, 4. The Okta CLI will create an OIDC Single-Page App in your Okta Org. Angular Shared Services Mechanism . Nx has great tooling and built-in support for building micro frontends with Webpack and Module Federation.
