  • Establish communication protocols: As mentioned, effective communication between teams and modules is crucial in a micro frontend architecture. It is important to establish protocols and standards for communication early on to avoid any issues later on.
  • Implement version control: Version control allows for better collaboration and management of code changes across multiple teams working on different modules. Git is a popular choice for version control in micro frontend architectures.
  • Use a shared component library: A shared component library can help ensure consistency and reduce duplication of code across multiple micro frontends. This also allows for easier maintenance and updates.
  • Embrace CI/CD practices: Continuous integration (CI) and continuous delivery (CD) practices are essential in a micro frontend architecture, as they allow for frequent updates, quicker deployment times, and better collaboration between teams.

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:
