Implementing Micro Frontends in Angular: Step-By-Step Guide

Published: 2024-07-11

Micro frontends are architectural styles in which independently deliverable frontend applications form a unified whole. This method enables teams to work independently on different parts of an application for scalability and easier maintenance. This guide will demonstrate how to implement micro frontends in Angular applications, the benefits and challenges, and the steps with code samples. Benefits of Micro Frontends Scalability: Teams can develop, test, and deploy features independently, scaling the development process. Autonomous teams: Different teams can work on separate micro frontends, using their preferred tools and frameworks. Maintainability: Smaller codebases are easier to maintain, understand, and refactor. Incremental upgrades: Micro frontends can be updated incrementally without affecting the entire application. Challenges of Micro Frontends Complexity: Increased complexity in managing multiple repositories and coordinating deployments. Performance: Potential performance overhead due to multiple independent bundles. Shared state management: Managing shared state across micro frontends can be challenging. Consistency: Ensuring a consistent look and feel across different micro frontends requires careful planning. When more than one team works on various areas of an application, differences in design and user experience usually creep in. To mitigate this, a solid design system and common component library should be established across all teams. This includes defining a set of UI components, styles, and guidelines that are uniform across the application. It also requires regular communication and collaboration between teams to align on design decisions and consistency.
