Angular Micro Frontends Proof of concept with pure angular toolchain. Each frontend can be implemented with different technology. That means the prototype assumes some shared concerns between the micro-frontends, which may seem contrary to more pure implementations of micro-frontends. Sometimes we have to extend the old architecture but we might not have the developers to implement or extend the architecture. For this example I’m going to set some basic inputs and outputs for the loaded web component. Using the previews item you can set a baseUrl here which might be helpful not only in production but also in local environments where developers need to run the WrapperApp and probably one of the WidgetComponents that they are working on.

Mann ( @kito99 ), Principal Consultant at virtua.tech . Communication with web components is possible via inputs and outputs, but complex logic could be an issue because of the async loading of the web components. Modern web apps are becoming more and more complex and most of the code lives on the client-side. But I found these 6 ways to implement. Have you ever wonder are there any frameworks or libraries to implement these and makes our job easier. 2. We get new innovative technologies on a regular basis. URLs: this is very important for production environments and for local environments. In the past years I've helped numerous companies building Micro Frontend architectures using Web Components. Since all the apps are divided and developed separately these are independent of each other. This doesn’t apply with the Micro-frontends as we do not share the code unless it is a dumb component. We need to install some dependencies and consider how to load the web components. But, this is not the case all the time. This is great for creating a component library. Summary. Micro-frontends with Web Components Using web components as a wrapper for both Angular and React components, I am going to show them working alongside each other in a single application. @angular/elements: this angular library contains the methods for converting the component into a web component, ngx-build-plus: Extends the Angular CLI's default build behavior.

Since we are loading all the apps on page load, we are not defining any specific context paths. There are two frameworks currently which implement this architecture: You don’t need frameworks to implement but, using one of these makes your transition from monolith to micro frontends easier. Wiredjs is really cool, but is also an example of a (mostly) framework agnostic ui-component library, as it is based on web components.

You can access the whole application on http://localhost:4200/. Persoonlijk zie ik heel veel voordeel in het volgen van het SRP en je code loosely coupled te schrijven in combinatie met de micro frontend architectuur. For example, Some teams have the flexibility and time to introduce and test newer versions of the same stack. Micro-frontends are small applications mostly divided by subdomain or functionality working together to deliver a larger application. When it comes to micro frontends each app has few unit tests and executes its own unit tests and can be run independently. What is Micro Frontend?
