What are the advantages and disadvantages of micro frontends?

Advantages of micro frontends:

• Development scalability: different teams can work independently on separate parts of the application.
• Technological flexibility: different frameworks and libraries can be used for different micro frontends.
• Error isolation: a failure in one micro frontend does not cause the entire application to crash.
• Simplified maintenance and updates: parts of the application can be updated without a full release.

Disadvantages of micro frontends:

• Integration complexity: communication and routing between micro frontends need to be configured.
• Increased overhead: loading multiple bundles can increase load time.
• Code duplication: shared dependencies may be duplicated, increasing size.
• State management: maintaining global state across micro frontends is challenging.

Example: a large online store can divide the frontend into micro frontends for catalog, cart, and user profile, allowing different teams to work in parallel and independently.
