A web app with micro-frontend approach is a web application that is divided into smaller, independent parts (known as micro frontends) that can be developed and deployed independently. Each micro frontend represents a self-contained, modular part of the application with its own codebase, framework, and UI. The overall user interface is then composed of these smaller parts, which can be loaded independently and asynchronously.

Here's an example of how you could create and define a web app with micro-frontend approach:

Identify the micro frontends: The first step is to identify the different parts of the application that can be broken down into micro frontends. For example, a shopping website could have micro frontends for the homepage, product catalog, shopping cart, checkout process, and user account management.

Choose a framework: For each micro frontend, choose a framework that fits the specific requirements and development team. Popular choices include React, Angular, Vue.js, and Web Components.

Define the communication protocol: The micro frontends must be able to communicate with each other to create a cohesive user experience. This can be done through a well-defined API or by using a message broker such as RabbitMQ.

Create a common styling system: Since the micro frontends are developed independently, it is important to have a common styling system to ensure consistency across the entire app. This can be done through a shared CSS file or by using a CSS-in-JS library.

Implement a deployment strategy: Each micro frontend can be deployed independently, but it is important to have a deployment strategy in place to ensure that changes are released in a coordinated and controlled way.

Set up a gateway: Finally, the micro frontends need to be composed into a single user interface. This can be done by setting up a gateway that serves as the entry point to the application and handles the routing and loading of the individual micro frontends.
