What is Micro Frontend Architecture: Benefits & Best Practices

Published on November 2nd, 2023

Micro frontend architecture is a cutting-edge software development approach that has gained significant popularity in recent years. It revolves around the concept of breaking down a large front-end application into smaller, more manageable units called micro frontends. These micro frontends are designed to be modular and independent, each responsible for a specific feature or functionality of the application.

By adopting a micro frontend architecture, development teams can benefit from improved maintainability, scalability, and flexibility in their projects. The modular nature of micro frontends allows teams to work on different parts of the application independently, facilitating parallel development and faster iteration cycles. It also enables easier testing, as each micro frontend can be tested in isolation, ensuring higher code quality and reducing the risk of introducing bugs.

Another advantage of the micro frontend approach is the ability to deploy each micro frontend independently. This means that teams can release updates and new features without affecting the entire application, resulting in faster and more frequent deployments. Additionally, the independent deployment of micro frontends allows for better fault isolation, as issues in one micro frontend won’t impact the overall application’s functionality.

Overall, the micro frontend architecture empowers development teams to build complex front-end applications with greater efficiency and agility. It promotes collaboration, modularization, and faster development cycles, enabling teams to deliver high-quality software that meets the evolving needs of users and businesses.

What is a Micro Frontend Architecture?

A Micro Frontend Architecture is an innovative and cutting-edge approach to building front-end applications. It revolves around breaking down the application into smaller, self-contained units known as micro frontends, which act as the fundamental building blocks. Each micro frontend is responsible for a specific feature or functionality of the application, ensuring modularity and reusability.

With this architectural style, teams can develop, deploy, and maintain micro frontends independently, providing scalability and flexibility to the overall system. This enables developers to work on different parts of the application simultaneously, promoting faster development and easier maintenance.

Furthermore, the adaptability and evolution of each micro frontend individually ensure that the application remains robust and up-to-date, even as new features are introduced. This allows for seamless integration of new functionalities without disrupting the existing system.

How do you handle Routing in a Micro Frontend Architecture?

In a micro frontend architecture, routing can be handled in multiple ways. Some popular methods include:

• Client-side routing: With this approach, the routing logic is handled by the client-side code itself. Each micro frontend module has its own router and is responsible for handling its own routes.
• Server-side routing: In this approach, the server handles all routing requests and serves the appropriate micro frontend based on the requested route. This allows for easier management of routes but can lead to slower performance.
• Hybrid routing: As the name suggests, this method combines both client-side and server-side routing. The server handles initial requests and then passes control over to the client-side router for further navigation within that particular micro frontend.

It is important to carefully consider which approach is best suited for your specific micro frontend architecture and project requirements. Additionally, it is important to ensure that the chosen routing method works well with other components and modules in your architecture.

Benefits of using a Micro Frontend Architecture

There are several benefits to using a micro frontend architecture:
