Exploring Import Map, Micro Frontends, and Nx Monorepos

Default Browser Flow

Let’s recall how a web application is executed. The first task is always to fetch the index.html file. The browser loads all the resources specified in this file. During this process, JavaScript, stylesheets, and other resources are loaded, with additional requests made as necessary.

Micro Frontend Architecture

The Micro Frontend architecture is a method of breaking down a frontend application into smaller, more manageable pieces. Each piece is responsible for a specific feature or domain of the application. This allows for the integration of different systems, enabling teams to operate independently while still producing a consistent product.

What is an Import Map?

Import Map is a browser technology that directly supports JavaScript modules in the browser. It allows you to map library names to URLs, improving readability and maintainability. For example, you can easily load moment.js with the following code:

<script type="importmap">
  {
    "imports": {
      "moment": "https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.30.1/moment.min.js"
    }
  }
</script>

This makes it easy to use modules when loading them in the browser.

Implementing Scalable Architecture with Nx

Nx is a powerful toolkit that makes it easy to share code, enhance visibility, performance, and adherence to rules through monorepos. It is particularly efficient in CI/CD processes, as it only executes tasks on affected code.
